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.

We have examined the relaxational response to the water extract of Angelica gigas $N_{AKAI}$ (AG), Gingko biloba $L_{INNE}$ (GB), Acanthopanax senticosus $H_{ARMS}.$ (AP) and Augumented-Four-Substance Decoction (AG-FSD, GB-FSD, AP-FSD) in isolated thoracic aorta from sprague dawley(SD) rat. Rat thoracic aorta was investigated in vessel segments suspended for isometric tension recording by polygraph. Responses to AG, GB, AP and AG-FSD, GB-FSD, AP-FSD were investigated in vessels precontracted with 5-hydroxytryptamine(5-HT) were compared in vasodilation effect. We found that the thoracic aorta segments responded to AG, GB, AP and AG-FSD, GB-FSD, AP-FSD with a dose-dependent vasodilation. The 5-hydroxytryptamine induced contraction at $10^{-4}M$ were inhibited by 26.3%, 75.8%, 87.5% and 6.9%, 22.6%, 30.8% after addition of the 0.1 g/mL water extract of AG, GB, AP and AG-FSD, GB-FSD, AP-FSD. In conclusion, AG, GB, AP and AG-FSD, GB-FSD, AP-FSD induced relaxation in the isolated rat thoracic aorta were composed of dose-dependent relaxation. AP-FSD has very potent vasodilation.
