- 中文摘要: Twenty components (including a new flavanone) were isolated and identified from the whole plant of Anaphalis sinica Hance. Their structures were determined on the basis of spectral analysis and chemical transformation. These components are 6-[(5-methyl-6-ethyl-4-hydroxy-pyrone-3-yl)-methylene]glabranine (1), kaempferol (2), tiliroside (3), quercetin (4), quercetin-3-O-β-D-glucoside (5), scutellarin (6), 5,7-dihydroxy-8-methoxyflavone (7), 5,7-dihydroxy-4''-methoxy-flavone-7-O-α-L-rhamnopyranosyl(1→6)-β-D-glucopyranoside (8), helipyrone (9), 4''-hydroxydehydrokawain (10), panamin (11), ursolic acid (12), pomolic acid (13), 3-acetyloleanolic acid (14), a mixture of N-(2-hydroxy-acyl)-4-hydroxy-8(E)-ene-sphingenine (15), O-methyl-D-inositol (16), a mixture of β-sitosterol (17) and stigmasterol (18) and a mixture of daucosterol (19) and stigmasterol-β-D-glucoside (20). Among them, 6-[(5-methyl-6-ethyl-4-hydroxy- pyrone-3-yl)-methylene]glabranine (1) is a new compound, and 13C NMR data of panamin (11) is reported for the first time.
