The Pharmacognostical Studies of Angelica Plants in Korea (II) A Classification Method of the Roots of some Anegelica Genus Plants by Thin Layer Chromatography

한국산 anglica 속식물의 생약학적연구 (II) 수종 Angelica 속식물근의 Thin Layer Chromatography를 이용한 감별법에 대하여

The internal structures of "Chunho", "Kangwhal" and "Dangui" and their original plants had been compared with each other in the prior report. Coumarin derivatives, khellactone from the roots of Angelica purpuraefolia $C_{HUNG}$ and decursin and decursinol from A. gigas $N_{AKAI}$ were also isolated. In this report, we made a simple and convenient identification method for the powdered drugs of several Angelica genus by using a thin layer chromatogrophic technique. The ehter extract of the powdered drugs were applied to a silica gel plate, and was developed with n-hexane and ethyl acetate (1:1) mixture. The characteristic U.V. absorption patterns of each drug were shown.
