바디나물 과실의 Furanocoumarin 성분연구(Ⅱ) = Study on the Furanocoumarin Constitutents in the Fruits of Angelica decursiva

다국어 초록 (Multilingual Abstract)

Angelica decursira Fr. et Sav. is widely distributed in Korea, but has so far not been investigated chemically. The six kinds of chemical constituents which are substances, Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, and Ⅵ, are isolated. Substance Ⅰ∼Ⅴ is identified as β-sitosterol. isoimperatorin, imperatorin, bergapten and umbelliferone.
Substance Ⅵ is suggested as a new substance based on chemical and spectral discussions. The molecular formula of substance Ⅵ shows C_16H_11O_5 and its melting point is 107℃. Due to the spectral data, it is confirmed that substance Ⅵ is a derivative of psoralen. Substance Ⅵ shows different data of m, [a]D, UV, IR, and NMR compared with those of the known psoralen substances as heraclenin. At the NMR spectrum, ppm : 7.65(3H)of substance Ⅵ shows at lower field than Koreanin. Xanthotoxin, methylate of xanthotoxol, is obtined by methylation of xanthotoxol which is derived by hydrolysis of substance Ⅵ. This fact confirmed that the side chain of substance Ⅵ is attached on 8 position of psoralen. The side chain at the 8-position of substance Ⅵ is confirmed β, γ-oxido-isoamyloxy group due to IR, NMR, Mass spectral data. Author wish to name substance Ⅵ as “Badinin” and suggests badinin as 8-(β, γ-oxido-isoamyloxy) psoralen.
