jaceosidin and kaempferol

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.

Study on the flavonoids from the air part of Eupatorium lindleyanum.. Alcohol percolation, silica gel column chromatography and re-crystallization et al.. Jaceosidin, kaempferol, quceritin, astragalin, trifolin and hypersoide were isolated from E. lindleyanum. Their structures were elucidated on the basis of spectral evidence.. Jaceosidin, kaempferol, quceritin, astragalin and trifolin were isolated from E. lindleyanum for the first time.
