The present study was carried out to identify traditional konwledges on Korean Campanulaceae plants and conduct a comprehensive review of them through analyzing phytochemistry and pharmacology of Korean Campanulaceae plants. According to the literature study, the ethnobotanical plants of Korean Campanulacae consisted of a total 18 taxa. Of them, 12 taxa including Platycodon grandiflorus, Adenophora triphylla var. japonica, Codonopsis lanceolata and others have been used as ethnomedicinal plants. These plants have been used for the treatment of 49 diseases such as cold, asthma and postnatal care. Phytochemical studies have identified the constituents present from Korean Campanulaceae (Adenophora, Codonopsis, Platycodon, Campanula and Asyneuma). A wide range of chemical compounds comprised 109 triterpenes, 8 sterols, 4 polyacetylenes, 21 alkaloids, 14 flavonoids, 14 phenolic acids, 11 phenolic glycosides, 8 phenylpropanoids and 22 other compounds. Pharmacological studies of these compounds have demonstrated immuno-stimulating, anti-inflammatory, anti-asthmatic, apophlegmatic and anti-allergic effects. They have also shown antioxidant, estrogenic, anti-diabetic, hepatoprotective, neuroprotective, antinociception and anti-tumor activities, as well as anti-obesity and cardiovascular effects. In light of traditional knowledge and phytochemical and pharmacological studies summarized, uses of Korean Campanulaceae based on traditional knowledge (for the treatment diseases and conditions of respiratory, pregnancy, childbirth, puerperium, genitourinary, circulatory, musculoskeletal and other systems) have been supported by phytochemical and pharmacological studies.

Background: Ma-huang (Ephedra sinica) has been widely used to treat respiratory disease in oriental medicine for over a hundred years. Ma-huang preparations contain approximately 1.25% ephedrine alkaloids. Recently, the ephedra alkaloids have received much press lately due to adverse effects in those using whole extracts as 'dietary supplements' for weight loss or athletic performance enhancement, and these reports are troubling given the increasing use of Ma-huang by the general public. The purpose of this report is to determine the proper dosage to minimize adverse effects and maximize the potential curative value. Objectives : The object of this study was to find an effective yet low risk dosage of Ma-huang. Methods : The study was designed as a double-blind randomized placebo-controlled trial. The subjects of this study were 26 adults between 20 to 40 of age who agreed to participate in this study. They were allocated through randomization into three groups. Each group took three opaque capsules three times a day. A group (N=9) took one Ma-huang capsule and two placebo capsules, B group (N=8) took two Ma-huang capsules and one placebo capsule, C group (N=9) took three Ma-huang capsules. The total trial periods was two days. To compare the adverse effects of Ma-huang according to dosage, blood pressure and pulse were checked, and other adverse effects were assessed using a morning questionnaire, patient's global assessment scale and Wong-Baker faces pain rating. Results : The following result were obtained: 1. After taking 18 g of Ma-huang per day, pulse rate had a significant increase. 2. After taking more than 6 g of Ma-huang per day, palpitation would be increased significantly. 3. After taking more than 18 g of Ma-huang per day, tiredness would be increased significantly. Conclusion: According to the results, 12 g of Ma-huang per day will minimize adverse effects and maximize the potential curative value.

The effect of Eruca sativa seed extract (SE) on nuclear factor kappa B (NF-${\kappa}B$), cyclooxygenase-2 (COX-2) and B-cell lymphoma-2 (Bcl-2) gene expression levels was investigated in rat mammary gland carcinogenesis induced by 7,12 dimethylbenz(${\alpha}$)anthracene (DMBA). DMBA increased NF-${\kappa}B$, COX-2 and Bcl-2 gene expression levels and lipid peroxidation (LP), while, decreased glutathione-S-transferase (GST) and superoxide dismutase (SOD) activities and total antioxidant concentration (TAC) compared to the control group. After DMBA administration, SE treatment reduced NF-${\kappa}B$, COX-2 and Bcl-2 gene expression levels and LP. Hence, SE treatment reduced inflammation and cell proliferation, while increasing apoptosis, GST and SOD activities and TAC. Analysis revealed that SE has high concentrations of total flavonoids, triterpenoids, alkaloids and polyphenolic compounds such as gallic, chlorogenic, caffeic, 3,4-dicaffeoyl quinic, 3,5-dicaffeoyl quinic, tannic, cinnamic acids, catechin and phloridzin. These findings indicate that SE may be considered a promising natural product from cruciferous vegetables against breast cancer, especially given its high antioxidant properties.

The present study was conducted to compare the relative efficiency of four different breeding methods in tobacco varietal development. A single Fl hybrid plant from cross of two flue-cured cultivars of Nicotiana tabacum L Bright Yellow 4(BY4) and NC95, was selfed. F2population above cross was screened for resistance against bacterial wilt caused by Pseudommonas solanacearum E.F.Smith under the naturally infested field conditions, and the 30 lines were developed from F2 individual plant by anther culture (ADH), maternal method utilizing Nicotiana afpicana (MDH), single- seed descent(SSD) and Bulk breeding method, respectively. All characters except content of total alkaloids of ADH and MDH which wore bred by haploid methods reduced more than that of lines bred by conventional methods(SSD & Bulk) : however, the yields were 8% lower than other lines. The total alkaloid content of ADH was higher than that of MDH, and yield was reduced about 4n even though the number of leaf was identical with the MDH. All other characters of ADH were also reduced significantly. In the lines bred by conventional methods, population developed by SSD showed significantly wider leaf width, shorter plant height, later days to flower, and lower in percent reducing sugar than those by Bulk. The populations derived from haploid method showed greater phenotypic variance and wider range of variation than conventionally developed ones. The results obtained indicate that selection will provide a significantly greater genetic gain for leaf number and leaf length in the ADU and MDH populations, and for plant height and days to flower in the SSD and Bulk populations.

The whole herbs of solanum nigrum L were extracted in boiling water (SNL-W), and the extracts were separated with butyl alcohol fraction (SNL-W/B) and aqueous fraction (SNL-W/W) by the solvent extraction method. The total alkaloid and total saponin content mensuration were used to identify the alkaloid composition of methanol fraction extracted from the aqueous fraction. The venom of honey bee was used to induce the rat peritoneal mast cell to secreting the histamine. The results show that the water soluble alkaloid composition of solanum nigrum L (SNL-W/W/M) has a significant inhibitory effect on the histamine release.

Hexane, ethyl acetate and methanol extracts of whole plant of Boerhavia diffusa were screened for phytochemical and biological activities. Qualitative phytochemical screening via colorimetric method and the quantitative estimation of phenolic and flavonoid content were performed. Antioxidant assay using DPPH scavenging method was studied. Antimicrobial screening of plant extracts was done by cup diffusion technique. Cytotoxic activity of B. diffusa was studied by brine shrimp bioassay and anthelminthic activity was evaluated in vitro in Pheretima posthuma. This study revealed B. diffusa as a source of various phyto-constituents such as alkaloids, glycosides, saponins, tannins, carbohydrates, cardiac glycosides, flavonoids and terpenoids. Quantitative estimation of total phenol was found to be maximum in BEE i.e. $29.73{\pm}0.88$, BME $19.8{\pm}2.02$ and in BHE $9.15{\pm}0.304mgGAE/g$. Similarly, the total flavonoid content was found to be $17.44{\pm}0.75$ in BEE, $14.43{\pm}0.23$ in BHE and 3.678 mg QE/g in BME. Ethyl acetate extract showed its antibacterial activity against all tested pathogens except Escherichia coli whereas Staphylococcus aureus and Salmonella Typhi were resistant to methanol and hexane extract. The zone of inhibition (ZOI) of ethyl acetate extract against S. Typhi and B. cereus was found to be 18 mm and 14 mm respectively. The MIC value of BEE in S. Typhi was $3.125{\mu}g/ml$ and in B. cereus was $12.5{\mu}g/ml$. The preliminary screening of anticancer property of B. diffusa i.e. BSLT in methanol was found to be $165.19{\mu}g/ml$. B. diffusa was also found to contain anthelmintic property. The study helped in further exploration of medicinal properties of B. diffusa by phytochemical screening and biological activities paving the path for study and investigation in this plant.

All the parts of lotus, including the seed, rhizome, leaf, stalk, petal, anther, pericarp, and fruit receptacle, have been used in traditional medicine system as a health beneficial supplement. However the most usually used from lotus plant is only the root. Therefore in this study, it will be discussed more the utilization of other parts of the lotus, namely the flower of lotus. The petals and stamens of lotus actually are also rich in bioactive components such as flavonoids and alkaloids, are used in the treatment of tissue inflammation, cancer, skin disease, and also for us as antidotes. One of the biotechnological process that can be used to improve the nutritional content, sensory, and also antioxidant activities is fermentation process. The final product desired from the fermentation process in this study is vinegar. The microbial strain powder used is Uinkin fermented powder with three variations of fermentation. The variations given in this study were initial sugar 32%, 24%, and 14% with the same fermentation temperature, $35^{\circ}C$ for 3 months. The results obtained showed that the pH value and sugar content of products during the fermentation process were decreasing during the fermentation process, with total polyphenol content of $283.7{\pm}97.6mg/100g\;QAE$, and total flavonoid content of $3.3{\pm}0.0mg/100g\;QAE$. For the DPPH radical scavenging ability of the fermentation product also increased in a concentration dependent manner, with ORAC activity of the product showed a high activity of $20.7{\pm}0.41{\mu}M$ TE. Therefore, fermentation process can be the one of method for improving the product. The efficiency of lotus flower vinegar fermentation can be reached with an initial sugar condition of 25% (sample B).

The process of the forced aging of flue-cured tobacco leaves were studied extensively from various scientific points of view. The Flue-cured tobacco leaves were inoculated and fermented with nicotine resistant Hansenula yeast, or the leaves were subjected under simple forced aging. The above two processes of forced aging were studied from the summarized points of microbiology, physics, chemistry, and biochemistry, and the resulted products ware compared in their physical, chemical and biochemical quality determining factors with that of raw material tobacco leaves (dried-tobacco leaves) and 2 years aged high quality tobacco leaves. The summary results were as follows. 1) The Korean flue-cured tobacco leaves, were forcedly aged under the basic optimum aging condition, temperature $40^{\circ}C$, moisture contents 18%, relative humidity 74%. It was found that this aging condition was the best in bringing the quality of forcedly aged tobacco leaves to the utmost state. 2) Under this optimum temperature and moisture condition of forced aging in about 20 days the forcedly aged tobacco leaves both with yeast inoculation and without yeast inoculation showed the equivalent tobacco qualities comparable with that of more than 2 years aged tobacco leaves. 3) The forcedly aged tobacco leaves both with and without yeast inoculation under $40^{\circ}C$ temperature and $74^{\circ}C$ relative humidity achieved the necessary quality determining physical and chemical changes in about 20 days. 4) The microbial changes during the forced aging were as follows. The population of yeasts and bacteria increased until to 15 days of aging, then decreased thereafter. Whereas the molds grew continously until the end of fermentation. 5) The tobacco quality determing physico-chemico-properties of yeast inoculated aged and simple forcedly aged tobacco leaves, progressed as the follows in time. As the forced aging progresses, swelling and combustibility properties were improved. The pH, total reducing materials, total sugars, alkaloids contents decreased. The contents of organic and ether extractable materials increased. The total nitrogen, protein, crude fiber, ash contents showed no changes. The color properties, excitation purity, luminance, main wave length, showed equivalent changes comparable with that of 2 years aged tobacco leaves. 6) The changes in chemical components in yeast treated and simple forcedly aged tobacco leaves during $15{\sim}20{\;}days$ of forced aging were as follows. The following chemical components decreased as the aging. Sugars-sucrose. rhamnose, glucose. Pigments-chlorophyll, carotenes, xanthophyll and violax anthine. Polyphenols-rutin, chlorogenic and, coffeic acid. Organic acids-iso-butylic, crotonic, caprylic, galacturonic, tartaric, succinic, citric acid. Alkaloids-nicotine, nornicotine. The following components increased as the forced aging progressed. Sugars-frutose, maltose, raffinose. Amino acids-proline, cystine. Organic acids-formic, acetic, propionic, n-butyric, iso-valeric, n-valeric, malic, oxalic, malonic, ${\alpha}-ketoglutaric$, fumaric, glutaric acid. 7) During the forced aging of tobacco Leaves the oxygen-uptake decreased gradually. The enzyme activities of polyphenol oxidase, ${\beta}-amylase$ ${\alpha}-amylase$ decreased gradually. The activities of the enzymes, catalase, and invertase increased once then decreased at the later stage.

Cigarette smoking is known to suppress both 1-methy14-phenyl-155,Ltetrahydropy-ridine (MPTP)-induced parkinsonism and idiopathic Parkinson's disease (PD). However, the precise mechanism underlying its protective action against PD is not clearly elucidated yet. In order to find possible clue on the mechanism of protective action of smoking, we investigated the inhibitory effect of cigarette smoke components on rat brain mitochondria1 monoamine oxidase B (MAO-B), responsible enzyme for the activation of MPTP to its toxic metabolitesr and identified the components having an inhibitory potency on this enzyme from cigarette smoke. Total 31 eligible constituents including nicotine were selected from cigarette smoke condensates via solvents partitioning and silica gel chromatographic separation, and inhibitory potencies of 19 components on MAO-B were determined. Hydroquinone and methylcatechol, the phenolic components, showed the strongest inhibitory potencies on MAO-B activity in the components tested. 3,4-Dihydroxybenzylamino, myosmine and indole in basic fracton, eugenol in phenolic fraction, and farnesol in neutral fraction also inhibited the enzyme activity dose-dependently. Among tobacco alkaloids tested only myosmine was effective for the inhibition of this enzyme. These results suggest that the decrease in MAO-B activity by such components derived from cigarette smoke seems to be related to the suppression of MPTP-induced neurotoxicity and to the less incidence of Parkinson's disease in smokers than in nonsmokers.

Objectives : Ma-huang is a traditional Chinese medicinal herb, derived from Ephedra sinica Stapf and other Ephedra species, used to treat asthma, nose and lung congestion, and fever with anhidrosis. It contains 0.5-2.5% by weight of total alkaloids, of which ephedrine accounts for 30 to 90%. Recently, Ma-huang has been used as a source of ephedrine in many dietary supplements formulated for the treatment of obesity, since ephedrine has been found to be effective in inducing weight loss in the obese. In this study the effects of the methanol extract of Ma-huang on the adipocyte of epididymal and brown fat pads in rats fed a high fat diet for six weeks were studied. Methods : Male Sprague Dawley rats weighing an average 94g (4 weeks old) were fed either a regular diet (RE) or a high fat diet (HF), and the HF group was subdivided into a Ma-huang methanol extract (30mg/100g body weight) group (HF+MH). The weight of epididymal fat pad and brown adipose tissue were measured. The cell size and cell number per unit area of epididymal fat pad were investigated. Results : The yield weight of methanol extract of Ma-huang was 3.63mg per l00g of Ma-huang. The body weight gain of the HF group was similar with that of the HF+ MH but higher than that of the RE. The weights of the epididymal fat pads and brown adipose tissue of the RE group were lower than those of HF and HF+MH groups. The cell sizes and numbers per unit area of epididymal fat pads of the RE and HF+MH groups were larger than those of HF group. The cell numbers per unit area size of epididymal fat pads were the smallest in the RE group. Conclusions : It could be concluded that the Ma-huang extract has no effect on the epididymal fat pads in rats fed a high fat diet and the clinical application of Ma-huang for the treatment of obesity should be re-considered.
