A method using coloric and spectrophotometric detection have been developed for the identification of the tertiary or quaternary alkaloids contained in Corydalis tuber and its preparations. The principle is based on the formation or decomposition of complex compounds. The complex compound of the tertiary and quaternary alkaloids have been formed by adding tetrathiocyanatocobaltate [II] ion to the test soln. Diverse crude drugs were screened using this method and the results indicated that isoquinoline, aconitine-type alkaloids in crude drugs can be readily detected. The method is simple, convenient, reproducible and applicable to the verification of the crude drug Corydalis tuber and its preparations.

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.

The effect of Capricornidis Cornu (C.C) on the amount of total cholesterol, triglycerides, and phospholipid in serum from rabbit were observed. The preparations were extracted by methanol, and extracted samples were oraly adminstrated to the rabbits fasted for three days. After three days starvation, the amounts of total cholesterol and triglycerides in serum of the rabbit were markedly increased, while phospholipid was slightly decreased. The amount of total cholesterol and triglycerides were gradually decreased by adminstration of the extracted samples and were returned to the control leveles after 15 days. However, the amount of phospholipid was increased to higher than the control levels by adminstraion of the drug. According to the above results, it would be concluded that the extract of C.C. and crude drug preparation containing C.C. influences for the recovery of the increased amounts of total cholesterol and triglycerides by abnormal metabolism to the normal on rabbit.

대부분의 한방제제는 유종의 생략을 배합하여, 전제오하여 복용하든지, 물등의 용제로 추출하여 제제화하여 사용하는 경우가 보통이다. 그런데 생약은 그 자체에도 성분의 함량에 차이가 있고, 특히 추출이나, 제제화하는 과정에서 타생약이나, 성분의 영향을 받는 경우가 많아 제품을 일정하게 제조관리하기는 매우 어려운 실정이다. 그러나 근래에는 한방의 과학화에 많은 노력이 경주되고 있는 추세이므로 생약성분간의 상호작용을 검토하여, 생약제품의 규격화및 품질관리에 기여코자, 한방제제에서 가장 많이 사용되는 생약중의 하나인 감초와 감초를 함유한 제제에 있어서 감초주성분인 glycyrrhizin의 정량과 감초와 지생약과의 배합시의 영향에대하여 검토하고, 방향을 지시하고자 한다.

Hyangsayangwee-Tang, a combined preparation of crude drugs, which has been used for stomach and intestinal disorder, was examined for anti-spasmodic, anti-ulcerative and anti-emetive effects. Spontaneous motility of isolated ileum was strongly suppressed and inhibitory effects against contraction of isolated ileum induced by acetylcholine and barium chloride were shown in mice. And, contraction of isolated guinea-pig ileum by histamine was inhibited. In rats fundus preparations, Hyangsayangwee-Tang elicited strong relaxation and had antagonist effects against the spasm induced by acetylcholine and barium chloride. A significant inhibitory effect on the intestinal propulsion of barium sulfate in mice was shown. In pylorus-ligated rats, Hyangsangwee-Tang inhibited gastric secretion and showed a strong anti-peptic activity. Protective effects against gastric ulceration induced by pyloric ligation, water-immersion stress, histamine and aspirin were significantly recognized in mice and rats. Hyangsayangwee-Tang decreased cupric sulfate-induced vomitting in frogs.

Gami-Samhwang-San, a herbal prescription for obesity treatment, is composed of seven crude herbs such as Rehmanniae Radix Preparata, Ephedrae Herba, Scutellariae Radix, Acori Gramineri Rhizoma, Polygalae Radix, Typhae Pollen, Armeniacae Semen, Menthae Herba. In this study, marker substances in n-butanol fraction (SH-21-B) from Gami-Samhwang-San were analyzed by high performance liquid chromatography (HPLC) and acute toxicity of standardized SH-21-B was evaluated by good laboratory practices (GLP) guideline of Korea Food and Drug Administration. Therefore we confirmed that there were baicalin of 15.92%, amygdalin of 6.57% and ephedrine of 2.49% in SH-21-B. SH-21-B was administered in rats at dose of 0 mg/kg, 2,000 mg/kg, and 5,000mg/kg. Clinical signs of both sexes of rats were observed daily for 14 days after single oral administration. Two female rats one administered at 2,000 mg/kg and the other administered at 5,000 mg/kg, died, but no dead animal was observed among male rats. Therefore $LD_{50}$ in the female rat is observed to be 8,710 mg/kg, and MLD (Minimun Lethal Dose) of the male rat is observed to be more than 5,000 mg/kg.

One of the characteristics features of Chinese Medicine is recognized as the practical use of combinations of crude drugs in the forms of various prescriptions according to the symptoms of illness. Such crude drugs are mostly dried plant roots, rhizomes, leaves, fruits and seeds, sometimes dried animla organ preparations even fossils or minerals. In the oldest book of Chinese Medicine, Sang Han Ron, 113 prescriptions were described in which about 80 crude drugs were included, and in other old literature, Shin Nong Bon Tcho Keun, 363 crude drugs were recorded. Such drugs, in particular, those included in Sang Han Ron are generally low toxic, and the prescriptions are acting mild with less side effects, but obviously not so easy task to determine the effect of the indivisual drug from the total effects of various prescriptions which are generally consisted of many kinds of crude drugs. About 200 years ago, in the middle of Edo era, a Japanese medical doctor, Yoshimasu Todo wrote a series of books named "Yakucho", in which he described the essential various prescriptions in which the certain drugs plays the main role. This book is very suggestive to evaluate the effects of some Chinese drugs. The actual effects of Chinese medicine and drugs have widely been recognized by the East Asian peoples during their long age experiences, but still it has not been studied sufficiently by modern scientific methods to give generally acceptable evidences. During past some years, my collaborators and I have been engaged to study some well-known Chinese drugs chemically to find out the active principles in determining their chemical structures under the collaboration of pharmacologists, Prof. K. Takagi and his coworkers. In the present lecture, I would like to present two topics from our recent investigations: The studies on the principles of Paeony and Ginseng roots.
