한국산산형식물의 성분연구 VI 참당귀근의 Coumarin 및 당성분

The ether extract of Dang-Gui, the dried root of Angelica gigas N$_{AKAI}$, was placed into a column with aluminium oxide gel. The elution of it with a mixture of n-hexane and ethyl acetate afforded Nodakenetin (I) and the elution with a mixture of n-hexane, ethyl acetate, acetone and methyl alcohol yielded Umbelliferon (II) and Nodakenin (III). Three coumarin derivatives were identified by comparing with authentic samples. The existence of sucrose and glucose was also proved.
