Objectives : This study was to analyze definitions of herbal medicinal preparations, crude drug preparations, and new drugs from natural products in the relevant laws and regulations, understand the related problems, and propose directions for improvement. Methods : I analyzed the legal definitions in respect of herbal medicinal preparations, crude drug preparations, and new drugs from natural products in relevant laws and regulations since 1945, explained the problems, and suggested the solution-considering the academic stance of Traditional Korean Medicine and the dualistic medical and pharmaceutical system. Results : Regarding the current laws and regulations that are relevant to herbal medicinal preparations, we should 1) clarify the boundaries between the duty of physicians and that of pharmacists, 2) limit the principles of Korean Medicine as well as the contents of the related textbooks, 3) find a way to protect the intellectual property rights for herbal medicinal preparations, and 4) establish a separate standard for drug classification regarding herbal medicinal preparations. In case of crude drug preparations, we should 1) clarify the meaning and limitations of the phrase, "the point of view of Western medicine," and 2) establish a classification standard for drugs that are used in Korean Medicine and clarify the boundaries between herbal drug preparations and crude drug preparations. Furthermore, laws and regulations apropos of new drugs from natural products do not actually fit the concept of "new drug," and due to subordinate laws, a supplement to a new drug submission is contradictorily misclassified as a new drug from natural products. Conclusions : The problems of legal definitions of herbal medicinal preparations, crude drug preparations, and new drugs from natural products have emerged in the process of giving approval to drugs that are made of herbs and natural products under the dualistic medical and pharmaceutical System. Laws and regulations that differentiate the process of approving herbs that are used in Korean Medicine and the others should be established.

To fine out the anti-inflammatory activities of the C. fragile. and its mechanism were investigated in macrophages induced by Peptidoglycan (PGN). Treatments of macrophages with 100 ug/ml of ethanol extract of Codium fragile (EECF) inhibited PGN-induced IL-6, NO and PGE2 production in a dose-dependent manner as well as expression of iNOS and COX-2. EECF inhibited PGN-induced extracellular signal-regulated kinase (ERK) 1/2, JNK 1/2 and p38 MAPK phosphorylation, which suggests that EECF inhibits IL-6 and NO secretion by blocking MAPKs phosphorylation. These findings may help elucidate the mechanism by which EECF modulates RAW 264.7 cell activation under inflammatory conditions.

This study was carried out for establishment of toxicological monitoring system in oriental medicinal plants. Hence on our research, we used Banha(Pinellia ternata) and Kangbanha, Bubbanha, Jaebanha, Geokbanha by distinguished processing methods. These are frequently used in Bangyakhabpeon, which is one of the most well-known clinical book in oriental medicine. As we reviewed the reported documents, we judge homogentisic acid(HA) and 3,4-dihydroxybenzaldehyde(3,4-DBA) as poisonous substance and to verify its existence, we established analysis condition of HPLC by gaining sequential fraction extracts and studied the degree of its virulence to provide basic information on the guidelines of using this medicine. Optimum condition of HPLC was H₂O : MeOH : CH₃COOH (57:35:8) in HA and 3,4-DBA analysis. HA content of raw Banha was 11.03mg/100g and HA contents of its processed product were decreased. Exceptionally, Jaebanha was increased in 175.97% than raw Banha. 3,4-DBA content of raw Banha was 2.93mg/100g and 3,4-DBA contents of its processed product were decreased. These results will be applies in intake guideline establishment, quality control and stability evaluation of oriental medicinal plants.

The quality inspections items such as loss on drying, total ash, and acid-insoluble ash contents in herbal medicines, have a correlation with external sources of pollution, but are not themselves hazardous factors. Z-scores for standard normal distribution were used to investigate herbal medicines requiring quality control, which exceeds the regulatory limits of quality inspection. In total, 7,773 samples were analyzed based on plant parts. For the loss on drying, the numbers of items of herbal medicines requiring quality control are like these; 15 items for above-ground parts and 5 items for underground parts. For the total ash, 21 items for above-ground parts and 4 items for underground parts. For the acid-insoluble ash, 8 items for above-ground parts and 1 item for underground parts.

A rat chemokine, cytokine-induced neutrophil chemoattractant-1 (CINC-1) has chemotactic and activating properties to neutrophils. Rat kidney epithelioid NRK-52E cells contained 4 ng/ml of ClNC-1 as a basal level and their CINC-1 production was significantly increased by stimulation with lipopolysaccharide (LPS) of E. coli. Maximal induction of ClNC-1 was 58 ng/ml when 3 ${\mu}g/ml$ of LPS was treated to the NRK-52E cells. Inhibitory effects on CINC-1 induction in LPS-stimulated NRK-52E cells by extracts prepared from herbal medicines and wild plants in Korea were analyzed. At the final concentration of 100 ${\mu}g/ml$ , 9 species out of 304 species of herbal extracts exhibited more than 50% of inhibition on the CINC-1 induction. The active extracts prepared from Artemisia argyi, Lythrum salicaria, Machilus thunbergii, Magnolia sieboldii, Nelumbo nucifera, Prunus persica, Rubus coreanus, Sanguisorba officinalis, and Tripterygium regelii have been sequentially fractionated to obtain methylene chloride, ethyl acetate, butanol, and aqueous layers. Among solvent fractions of the active herbal extracts, methylene chloride fractions of Artemisia argyi and Magnolia sieboldii exhibited the highest inhibitory effects on CINC-1 induction in LPS-stimulated NRK-52E cells.

We investigated the antithrombotic effect of Acorus gramineus Soland (A. gramineus) from Korea and Acorus tatarinowii Schott (A. tatarinowii) from China in a rat model of arterial thrombosis induced by ferric chloride ($FeCl_3$). Thirty minutes prior to a 35% $FeCl_3$ application, Sprague Dawley rats were intraperitoneally injected with saline, A. gramineus and A. tatarinowii (100 mg/kg), respectively. Occlusion time of rats injected with A. gramineus was delayed significantly compared to that of the vehicle and A. tatarinowii. Thrombus weight was meaningfully decreased in rats injected with A. gramineus compared to the vehicle. Additionally, A. gramineus inhibited collagen fiber damage in vessel compared to the vehicle, but A. tatarinowii did not show a significant effect. Our results show that A. gramineus and A. tatarinowii from the same genus have different antithrombotic effects, and especially A. gramineus has a better antithrombotic effect than A. tatarinowii.

The activities of s-amylase, ${\alpha}-amylase$ and protease of three combination products containing digestive enzymes, antacids and herbal drugs on the Korean market were estimated. The effects of antacids and herbal drugs on the activities of digestive enzymes were investigated. Starch-saccarifying activity of s-amylase, starch-dextrinizing activity of ${\alpha}-amylase$ and protein-peptic activity of protease were estimated by Somogy, Mc'Credy, and Casein-Folin method, respectivley. The optimal pH of s-amylase, ${\alpha}-amylase$ and protease were pH 5.0, 4.8 and 7.0, rcspectively. The digestive activities at optimal pH continued about eight hours. The digestive activities of individual enzymes were reduced to 40-90% by antacids and were affected somewhat positively or negatively by herbal drugs. Enzyme activities of the combination products were also affected by pH and reaction time.

Simultaneous quantification of multiple marker compounds in herbal medicine by high performance liquid chromatography (HPLC) analysis is still a challenge due to the complexity in various parameters to be considered and co-existing multi-components. As a case study, a reliable HPLC method for simultaneous quantification of paeoniflorin from Paeoniae Radix and decursin from Angelicae Gigantis Radix in various commercial herbal medicine was developed based on analytical quality by design (AQbD) strategy. As a first step, risk assessment was performed to select the critical method parameters (CMPs) which were decided as organic mobile phase ratio and column oven temperature. In order to evaluate the effect of the CMPs on critical method attributes (CMAs) of peak resolution and tailing, central composite design (CCD) was employed. The final chromatographic conditions were optimized as follows: column- C₁₈, 4.6 × 250 mm, 5 ㎛ particle size; mobile phase- A: acetonitrile, B: 0.1% acetic acid water; detection wavelength- 235 nm for paeoniflorin, 325 nm for decursin; column oven temperature- 25℃; flow rate- 1.0 mL/min; gradient mobile phase system as Time (min) : % A, 0:14, 25:14, 30:50, 60:50, 61:100, 65:100, 66:14, 75:14. The method was successfully validated according to the International Conference on Harmonization (ICH) guidelines and piloted for ten commercial herbal medicines.

Objective : Lonicera japonica THUNB. a traditional herbal medicine, has been commonly used anti-inflammatory disease. It has been very complicated with respect to its sources on the market. The significant selection of medicine depends on its origin. However, it is difficult to discrimination criteria for confirming L. japonica authenticity using the senses. This study was performed to determine the discriminant analysis of L. japonica and L. confusa. Methods : The identification of L. japonica and L. confusa were performed by the classification and identification committee of the national center for standardization of herbal medicines. And we examined its differences using HPLC and genetic marker analysis. Results : The analytical pattern of High Performance Liquid Chromatography was determined from the corresponding peak curves ((E)-aldosecologanin, chlorogenic acid, luteolin 7-O-glucoside, sweroside). For L. japonica, additional unknown peaks were detected at 13.8 min, 20.6 min, and 36.9 min. And, we developed genetic marker using the the tRNA-Leu gene, trnL-trnF intergenic spacer and tRNA-Phe region of chloroplast DNA. By the method, 164 bp PCR product amplified from L. confusa was distinguished into L. japonica and L. confusa efficiently. Conclusion : Base on these results, two techniques provide effective approaches to distinguish L. japonica from L. confusa.
