  • The experiment was carried out to find aromatic constituent composition of Codonopsis lanceolata species grown in the native(Mt. lrwol, Youngyang, Kyungpuk Province) and the cultivated(Andong, Kyungpuk Province) areas from 1994 to 1995. The results were as follows : Air temperature and soil temperature at the native area were lower to $2{\sim}3^{\circ}C$, and to $2^{\circ}C$ than the cultivated area. Organic matter contents of plant grown at the native area higher than that of plants at the cultivated area by 4.8%. Crude protein content was higher in plant grown at native area than the plant grown in wild area but in case of crude saponin, plants grown at wild area was higher than that of native area. For inorganic element contents. K content is much higher than in the domesticated area as compared with wild area above ten over. And other elements such as Cu, Mn, Na and Mg were not remarkably different in contents. In the free amino acid compositions, argine was highest compared with other free amino acids, and Arginine content was higher in dometicated area. Recovery yield of essential oil of wild species grown at the cultivated showed 0.005%, but domesticated species was 0.004%. But both species at the native area were the same by 0.004%. Although composition of aromatic constituents in the two areas and species varied, total aromatic constituent was 21 kinds. Most aromatic constituents were aliphatic alcohols such as 1-hexanol, eis-3-hexanol, and trans-2-hexanol occupied by approximately 90% over. But three constituets as amylalcohol, furfuryl acetate, and 2-methoxy-4-vinyl phenol(MVP) were detected only in domesticated species.

  • Cheongkukjang was prepared by addition of medicinal herb powder (from Lentinus edodes, Codonopsis lanceolata BENTH et HOOK, or Houttuynia cordata THUNB) to improve Cheongkukjang quality and functional properties. Redness and yellowness (measured using Hunter’s color values) increased with increasing amounts of medicinal herb powder, whereas lightness (the third Hunter's color value) and pH decreased. Crude protein and lipid levels of Cheongkukjang decreased with increasing amounts of added medicinal herb powder, whereas powder addition did not affect either the moisture or crude ash content of Cheongkukjang. The major organic acids of Cheongkukjang were lactic acid, acetic acid, succinic acid, and citric acid, and acid levels increased as the proportion of medicinal herb powder in the Cheongkukjang preparation increased. The major amino acids of Cheongkukjang were glutamic acid, aspartic acid, leucine, arginine, and lysine and the principal fatty acids were linoleic acid, oleic acid, palmitic acid, and linolenic acid. Addition of medicinal herb powder to Cheongkukjang increased both crude saponin and quercetin contents. Sensory scores of Cheongkukjang containing 2% (w/v) medicinal herb powder were optimal in terms of both quality characteristics and sensory evaluation.

  • The aim of the present study was to evaluate of turmeric (Curcuma longa L.) on the physiological activities and oxidation inhibitory action. The effects of various solvents (distilled water DW, 70% ethanol and n-butanol) on the total phenolics content (TPC) of turmeric and their corresponding biological activity were studied. Bioactive compound of total saponin $7.506{\pm}0.349mg\;SE/g$ dry weight. Turmeric extracts yield were DW (17.11%), 70% ethanol (15.26%) and n-butanol (4.12%), respectively. Oxidation inhibitory action of the samples exhibited a dose-dependent increase. However, in the current study, none of the samples evaluated showed activity as strong as the BHA, ascorbic acid and EDTA. Results showed that extraction solvent had significant effects on TPC and oxidation inhibitory action (DPPH radical scavenging activity, ABTS radical scavenging activity, reducing power and ferric reducing antioxidant power) of n-butanol. Turmeric exhibited the antioxidant properties, which suggests that the plant material could be used for further studies as a potential source for bioactive and natural antioxidant.

  • The possibility of utilizing greet amount of by-product of ginseng (Panax ginseng C.A. meyer) plant-that is, production of ter from ginseng leaf, was studied and the results are summarized as follows: 1. Ginseng leaf contains more soluble matter than tea leaf (Thea sinensis) and the soluble matter is easily extracted by hot water. 2. Ginseng leaf has less tannin (2.2%) than yea leaf (7.89%). Therefore, it has less astringency than tea. 3. Vitamin C content of ginseng leaf is not compared with that of tea leaf. In fact, ginseng leaf contains Vitamin C $50{\sim}110$ times of tea leaf. 4. Ginseng leaf contains $5.7{\sim}8.5%$ glycoside (dammaranes) and the ratio of panaxadiol to panaxatriol is $0.54{\sim}0.75$ that is, panaxatriol contents is high. 5. For the acceptability of the product related with the soluble matter contents and color the method of extracting 2g of ginseng leaf product in 200ml of water for 3 minutes is recommended. 6. As a result of evaluating the flavor characteristics and effective components of the products, product D which is produced by the process of steaming, drying and roasting is considered to have the best quality.

  • Large-scale cultures of plant cell, tissue, and organ have been achieved by using BTBB. When different sized BTBBs (5 L, 20 L, 100 L, 300 L, and 500 L) were tested for the culture of yew cells (Taxus cuspidata Sieb. et Zucc.), cell growth increment reached to 94.5% in SCV after 24 days of culture with 30% of inoculation cell density. However, there were some variations in the production of taxol and its derivatives among the BTBBs of different size. Approximate 4 ㎎/l of taxol and 84 ㎎/l of total taxanes were obtained by using a 500L BTBB after 6 weeks of culture. With a 20L BTBB, about 20,000 cuttings of virus-free potatoes (cv. Dejima) could be obtained by inoculating 128 explants and maintaining 8 weeks under 16 hr light illumination. The frequency of ex vitro rooting of the cuttings revealed as more than 99% under 30% shade. By incorporating two-stage culture process consisting of multiple bulblet formation in solid medium and bulblet development in liquid medium, mass propagation of lily through bioreactor seemed to be possible. In the case of 'Marcopolo', the growth of mini-bulblets in BTBB was nearly 10 folds faster than that of the solid medium. Time course study revealed that maximum MAR yield of ginseng (Panax ginseng C. A. Meyer) in a 5 L and 20 L BTBB after 8 weeks of culture was 500 g and 2.2 ㎏, respectively. By cutting the MAR once and/or twice during the culture, the yield of root biomass could be increased more than 50% in fresh weight at the time of harvest. With initial inoculum of 500 g of sliced MAR in a 500 L BTBB, 74.8 ㎏ of adventitious root mass was obtained after 8 weeks of culture. The average content of total ginseng saponin obtained from small-scale and/or pilotscale BTBBs was approximately 1% per gram dry weight. Based on our results, we suggest that large-scale cultures of plant cell, tissue, and organ using BTBB system should be quite a feasible approach when compared with conventional method of tissue culture.

  • This study was compared the quality of red ginseng and characteristic changes of physicochemical properties according to the storage period (non storage, two days, six days, eight days, ten days) and store temperature $20^{\circ}C, \;34^{\circ}C,\;-10^{\circ}C)$. The water content of the fresh ginseng has a tendency to decrease as storage time increases. When we store the fresh ginseng for 10 days, the ideal storage temperature is considered to be $34^{\circ}C$ degrees. The amount of total nitrogen has a tendency to increase more than that of no storage as storage period approaches to 10 days. In the storage temperature, the amount of total nitrogen has a tendency to increase in the order of 1) room temperature, 2) freezing storage, 3) cold storage more than no storage. Cold storage has larger contents of total phenolic compounds than room temperature and freezing storage according to storage temperature. When we analyze the changes of a relative density of eight elements, ginsenoside $Rb_1,Rb_2,Rc,Rd,Re,Rg_3,Rg_1\;and\;Rg_2$ in red ginseng's saponin Rf according to storage condition, the relative density of $Rb_1\;and\;Rg_1$ against Rf diminishes in each storage condition as storage time increases. And it is also thought that density change of ginsenoside appears because of the materials, and change tendency according to storage condition is not clear. From functional nature on the evaluation of the quality, taste and fragrance of red ginseng according to storage district, it is evaluated that it is most recommendable for red ginseng to be transported and stored in $3{\sim}4$ degrees to keep its best condition.

  • This study was carried out to know the effect of seed position on the size, contents of ginsenosides, free sugars, and fatty acids in ginseng seeds. Seed positions were classified by the three portions as center, middle and border in a seed cluster. Seed weight at center was light remarkably in comparison with those of seeds of at border and middle. The weight of embryo plus endosperm was in same tendency as seed weight. Percentage of single-seeded berry was smaller than that of the double-seeded, and the triple-seeded was rare. The percentage of the single-seeded increased from the border to the center. Size of the single -seeded seed was smaller than that of the double- seeded. Rate of dehiscence did not differ among different seed positions. The major ginsenosides in seed were Re, Rb$_1$, and Rb$_2$. The contents of Rb$_2$ and total saponin were highest in border, least in center, but reversed in Re and Rd. Major free sugars in seed were sucrose and glucose. The sucrose content was gradually decreased according to the seed position from border to center. Major fatty acids in the seed were oleic and linoleic acid. Contents of palmitic and linolenic acid were different according to the seed position.

  • To increase the quality of Korean traditional yakju, we prepared seed cultures by fermentation at $20^{\circ}C$ for 2 days after addition of 140% water, 3% nuruk and 1.5% yeast into cooked rice. After the 200% cooked rice, 120% water and 0.08% commercial saccharifying enzyme were added to seed cultures and fermented for 2 days at $20^{\circ}C$, wild ginseng was added and then further fermented for 5 days. Physicochemical properties of traditional yakju were investigated. Ethanol was produced (18.5%) by the addition of 1.2% wild ginseng. However, ethanol content was not increased by addition of microwave treated-wild ginseng and rice (either cooked rice or raw). The traditional yakju obtained by fermentation at $20^{\circ}C$ for 5 days, after 90 sec of microwave treated-wild ginseng was added into main fermentation broth, showed good total acceptability and also contained 791 ppm saponin.

  • This study was carried out to investigate the effect of the active ingredients from ginseng on paraquat(PQ) toxicity. Oxidative stress was induced by intraperitreatneal injection of PQ at a single dose of 25 mg/kg. Saponin treated groups were given protopanaxadiol saponins(PPD) or protopanaxatriol saponins(PPT)(5 mg/kg, orally) per day for 1, 3, & 7 days. We also investigated the relationship between lipid peroxidation and ginseng saponins by measuring the levels of superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase (GPx), reduced glutathione(GSH), malondialdehyde (MDA), and hydrogen peroxide(H$_2$O$_2$) in liver tissue. The activities of SOD, CAT, and GPx were generally high in the PPD group; the SOD activity on each day was the highest in the PPD group. The H$_2$O$_2$ content was the lowest in the PPD group. The GSH levels were significantly increased in the PPD. The levels of MDA(the end product of lipid peroxidation) were significantly lower in the red ginseng component groups than in the PQ group; the levels were especially low in the PPD groups. These results led us to conclude that the antioxidant effects of extracts from red ginseng prevent oxidative damage by direct antioxidant effects involving SOD, CAT, & GPx, and increasing the ability of the body to synthesize endogenous antioxidants.

  • Anemarrhena asphodeloides BUNGE is one of important medicinal crops, which has been collected or/and cultivated for its rhizomes. The main medicinal ingredient of the A. asphodeloides Bunge rhizomes is a saponin, which is known to have medical values for diaphoresis, sedatives and biuresis. However, studies on cultural methods and breeding works on this plant have not been made in detail. To increase productivity and to improve quality of crops, it is important to collect cultivated and wild lines, to classify them based on morphological and genetic characteristics, and to select superior pure lines at first. Therefore, total 20 A. asphodeloides lines collected were cultivated at the fieldof Chungnam Provincial Administration of Rural Development in 1995 to study the agronomic characteristics and to classify them based on morphological characteristics. Characteristics related with reproductive organ such as the number of spikes per plant and peduncle length showed greater variations than vegetative organrelated characteristics such as leaf length and rhizome length based on the coefficient of variation. Vigorous shoot growth resulted in better development of reproductive organs such as peduncle length and number of spikes per plant. However, the development of spikes was negatively correlated with chlorophyll content. Characteristics of underground parts were more significantly correlated with spike characteristics than aerial part characteristics. A. asphodeloides tested in this study were classified into 2 groups (group A and group B) based on centroid linkage cluster analysis. Group A showed more vigorous shoot growth with more leaves and spikes per plant, longer peduncle length, thicker peduncle diameter and higher shoot dry weight than group B. Group A could be further classified into 2 sub-groups based on leaf size, spike length and peduncle diameter, while group B also could be classified based on number of leaves, number of spikes and shoot dry weight.
