Substances I∼VII are isolated from the root of Glehnia littoralis which has been often used as a subsitute of Bang-Poong in Korea. White needle crystalline substance of C<sub>29</sub>H<sub>50</sub>O, m.p. 137∼139°was confirmed as β-sitosterol through elemental analysis, derivative synthesis, IR and physicochemical tests. Moreover, it was concluded that white needle crystal of C<sub>12</sub>H_8O<sub>4</sub>, m. p. 188∼189°was confirmed as bergapten, through a contrast test with standard substance and by UV and IR-spectra. It was found that substance III and VII coincided with the Rf values of imperatorin and umbelliferone and to its colors under the UV-ray, and its similarity to UV-spectrum can be recognized, but their melting points are remarkedly different respectively.
오갈피나무 Acanthopanax sessiliflorum의 성분연구(Ⅱ)
육창수(Chang Soo Yook),이동호(Dong Ho Lee),서윤교(Yoon Kyo Seo),류경수(Kyung Soo Ryu) 한국생약학회 1977 생약학회지 Vol.8 No.1
The chemical constituents of root bark of Acanthopanax sessiliflorum Seemann(Araliaceae) which is distributed in southern region of Korea are studied. The five kinds of chemical constituents are isolated from MeOH extract of root bark by column fractionation and purified by recrystallization. Substance I∼III were identified as stigmasterol, β-sitosterol and campesterol. Substance IV is suggested as a lignan substance based on chemical and spectral discussions. The molecular formula of substance V show C<sub>20</sub>H_(18)O_6 and its melting point is 120.5∼121.5°. Due to the spectral data, it is confirmed that substance V is a (+) sesamin of lignan.
