Evaluation method of crude drug preparations was studied in Saengmaek-san. Zig-zag TLC scanning profiles and high performance liquid chromatograms were obtained from Saengmaek-san and its each crude drug. A method using TLC densitometry and high performance liquid chromatography was established for the precise determination of ginsenoside $Rb_1$ in Saengmaek-san containing Ginseng Radix. Consequently, ginsenosicle $Rb_1$ content was 0.45-0.48 mg per g of Saengmaek-san. This method was found to be useful for the quality evaluation of oriental medicinal preparations.

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.
