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

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 CHUNG and decursin and decursin and decursinol from A. gigas NAKAI 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 ether extracts 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.
