This study was performed to confirm the physicochemical properties and physiological activities according to cultivar and parts of Ulsan sweet persimmons. The proximate composition of the sweet persimmons was moisture $77.68{\sim}84.65%$, crude ash $0.3{\sim}0.6$, crude fat $0.29{\sim}0.39$ and crude protein $0.52{\sim}0.61%$. Confirmed organic acids and free sugars in sweet persimmons were malic, citric, succinic, and fumaric acids, along with fructose, glucose and sucrose. The major fatty acids were linolenic, vaccenic and palmitic acids. Also, K is the highest mineral in sweet persimmons that accounts for the majority of mineral, more than 60% as $84.9{\sim}103.7mg%$. Contents of vitamin C, total phenolic compounds and flavonoids were the highest in Fuyu peel as 139.91, 169.36 and 60.79mg%, respectively, Electron donating ability and xanthine oxidase inhibition were the highest in Fuyu peel as $30.6{\sim}91.2$ and $26.3{\sim}91.9mg%$, respectively. Nitrite scavenging activity was higher in peel than flesh as $51.0{\sim}76.4mg%$ with slight difference depending on cultivar.

In this study, we have investigated the HPLC analysis methods and quantitative analysis of standard compounds for quality standardization of a medicinal crude drug GCSB-5, a herbal formulation consisting of 6 medicinal plants (Acanthopanacis Cortex, Achyranthis Radix, Ledebouriellae Radix, Cibotii Rhizoma, Glycine Semen, Eucommiae Cortex) which are used in traditional medicine to treat various bone disorders. HPLC analysis methods of acanthoside D(Acanthopanacis Cortex), 20-hydroxyecdysone(Achyranthis Radix) which were known standard compounds among 6 medicinal plants were developed on crude material and product. And validation of HPLC analysis methods were conformed for verification of HPLC methods by check to specificity, linearity, intra-day precision, inter-day precision and accuracy following ICH guideline. Content of acanthoside D and 20-hydroxyecdysone on raw material of GCSB-5 were decided at 0.577-0.578 mg/g and 0.311-0.312 mg/g. And we confirmed that content of acanthoside D and 20-hydroxyecdysone on GCSB-5 preparation were 0.302-0.303 mg/capsule and 0.113-0.115 mg/capsule.

In order to investigate the chemical and pharmacological characterization of crude drug processing, the triterpenoidal constituents of Glycyrrhizae Radix(GR) were examined. Processed GR has been often used to reinforce and change the efficacy of GR. Glycyrrhizin(GL) is one of the main constituents of GR. Following procedure described in the oriental medicinal reference, GR and GL were heated at $140^{\circ}C{\sim}240^{\circ}C$ in GC oven. And then, the content of GL in the processed GR and GL was analyzed by HPLC. GL was transformed to $18-{\beta}-glycyrrhetic\;acid\;mono-{\beta}-D-glucuronide(GM)$ and glycyrrhetic acid(GA) by processing at $170^{\circ}C$. Determination of the content of GL increasing the heating temperature showed that GL was decomposed by heat above $150^{\circ}C$. It was also found that the content of GL in GR processed by heat above $170^{\circ}C$ remakeably decreased.

Chinese medicine is a precious treasure inherited from ancient ancestors. It is accredited for the prosperous growth of the Chinese nations. However, the descriptions of the herbs in the ancient herbal are not in detail and the great numbers of herbs used which grows in wide geographic areas together with various local folk names, new substitutes and new folk medicines had increased, many Chinese herbs are composed of herbs that are labeled with identical names but actually are of different origins and different grades. Similar situation had occurred in China, japan and Korea In Taiwan, misused Chinese crude drugs are also very common in the past. This phenomenon had caused a lot of confusion and had great influence the clinical efficacy of the treatment. In the past, Professor Hong Yen Hsu, Na Chi, Woei Song Kan and Kung Yin Yen had studied the origins of Chinese crude drugs in Taiwan based on the morphological identification and found that the origins of Ma-Tou-Ling, Pu-Kung-Yin, Tu-Chung, Wang-Pu-Liu-Hsing, Pan-lan-Ken, Niu-Chi, Fang-Chi, Huang-Chi, PienHsiu and Sha Wan-Tzi are different from that of the species used in mainland China. In order to assure the quality and clinical efficacy of the crude drugs, besides the traditional morphological methods, we bad recently combined modem chemical and pharma-cological methods to assess drug quality. Drugs that have been evaluated without effects should be abandoned. The species of those commonly misued crude drugs used in compound formula preparations are also identified Based on the pharmacological results, a suitable species is recommended so as to improve the clinical efficacy of those preparations. In this paper, we like to report our recent studies on Niu Chi(Achyranthis Bidentatae Radix, Cyathulae Radix and Strobilanthis Radix). Fang-Chi(Arstolochiae Fangchi Radix, Stephaniae Tetrandrae Radix and Cocculus Radix) and Huang-Chi(Astragali Radix and Hedysari Radix) using comparative pharmacognosy methods.

Aconites distribute widely in northern hemispere of the earth reaching to arctic zone from warm and temperate one. Chinese crude drug 'Cho O'(草烏) has been used as a remedy for apoplexy, dyspepsia, neuralgia, chronic rheumatis etc. Though the botanical origin of the crude drug has been considered to be Aconitum species of Ranunculaceae, there has been no confirmation on it. To clarify the botanical origin of Cho O, the morphological and anatomical characteristics of the roots of Aconitum species growing in Korea, i.e. A. chiisanense, A. ciliare, A. jaluense, A. napiforme, A. proliferum, A. pseudoproliferum and A. triphyllum were studied. As the result, Cho O was proved to be the roots of Aconitum triphyllum, A. jaluense, A. chiisanense and A. napiforme.

Chinese crude drug 'Dang Gui' has been used mainly as a tonifying the blood, promoting blood circulation, relieving pain and moistening the bowels. To clarify the botanical origin of 'Dang Gui' from Korea, the anatomical characteristics of Angelica gigas, Angelica sinensis and Angelica acutiloba were studied. As a result, it was clarified that 'Dang Gui' from Korea was the root of Angelica gigas.

The Korean crude drug 'Suk Wi' has been used as the folk remedy for diuretic and gonorrhea. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of Suk Wi, studied on the morphological and anatomical characteristics of Pyrrosia species growing wild in Korea i.e., P. linearifolia, P. lingua, P. petiolosa, P. tricuspis and Suk Wi from Korea on Korean market. As a result, it was made clear that Suk Wi from Korea was derived from Pyrrosia lingua and P. petiolosa.
