난과식물의 생약학적 연구 = Pharmacognostical Studies on Orchidaceae Plants

다국어 초록 (Multilingual Abstract)

In order to estimate accurate originality of the important crude drugs, Gastrodia, Dendrobiurn, Bletilla and Cremastra spp. were investigated comparing their morphological, anatomical and physicochemical characteristics and antibacterial,
antifungal activities.
The results of the studies as follows:
1. In morphological and anatomical studies, Korean Gastrodia contained more mucilage duct and symbiotic fungi than imported Gastrodia. Korean Dendrobium contained starch grains but without starch grains in the imported Dendrobium from
China enclosed with thicken silicified wall. The corm of Cremasta appendicutata contained raphides of bundles with mucilage while the bulbs of Tulipa edulis containedseveral various starch grains form.
2. In physiological and TLC analysis, crude drugs in Orchidaceae contained common constituents with fluorescence and much mucilage.
3. The EtOH extracts of Gastrodia, Dendrobium, Bletilla, Cremastra showed
antibacterial activities againt B. subtilis and E. coli (Dendrobium>Gastrodia>Bletilla>Cremastra). But, no antifungal activities against C. albicans, A. niger were observed.
