【Abstract】 AIM To study the chemical constituents of Cibotium barometz(L.)J.Sm. [METHODS] To isolate and purify by using silica gel column chromatography and Sephadex LH-20 column chromatography and to identify the structures on the basis of IR, MS, 1H-NMR, 13C-NMR and other data. [RESULTS] Nine compounds were isolated and identified as palmitic acid(Ⅰ), β-sitosterol (Ⅱ), 1-mono-palmitin (Ⅲ), daucosterol (Ⅳ), caffeic acid(Ⅴ), protocatechuic acid(Ⅵ), protocatechuic aldehyde (Ⅶ), n-butyl-β-D-fructopyranoside(Ⅷ) and D-glucose(Ⅸ). [CONCLUSION] Ⅲ, Ⅶ,Ⅷ and Ⅸ were reported in Cibotium Kaulf. for the first time.更多还原
