摘要
从杭白菊(Dendranthema morifolium (Ramat. )Tzvel.)的乙醚部分分离出13个化合物。运用波谱技术和化学方法证明其中2个为新化合物,命名为棕榈酸16β,22α-二羟基假蒲公英甾醇酯(1)和棕榈酸16β,28-二羟基羽扇醇酯(2)。
Two new triterpenoid esters (1 and 2) and eleven known compounds were isolated from the ethyl ether extract of Dendranthema morifolium (Ramat.) Tzvel. By means of chemical correla- tion and spectral analyses (IR,FAB-MS, H-NMR, C-NMR),compounds 1 and 2 were established as 16β,22α-dihydroxypseudotaraxasterol-3β-O-palmitate and lup-16β,28-dihydroxy-3β-O-palmitate.
