Chemical constituents of Eupatorium lindleyanum / 中国中药杂志

ABSTRACT

To study chemical constituents of Eupatorium lindleyanum. Ethyl acetate extractive fractions were separated with silica gel and Sephadex LH-20 by column chromatography, and their structures were identified on the basis of spectroscopic analysis and chemical evidence. Sixteen compounds were separated and identified as scopoletin (1), 6, 7-dimethylesculetin (2), nepetin (3), eupatrin (4), luteolin (5), isoquerecitrin (6), jaceosidin (7), quceritin (8), kaempferol (9), rutin (10), cirsiliol (11), taraxasterylacetate (12), pseudotaraxasteryl acetate (13), pseudotaraxasterol (14), butanoic acid (15) and n-hexadecanoic acid (16). Of them, compounds 1-6 and 11, 13 and 15 were separated from this plant for the first time.
