| Abstract: | ObjectiveTo study the chemical constituents of the flowers of Pyrus pashia Buch.-Ham.ex D.Don. MethodsCompounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography.Their chemical structures were identified on the basis of spectral data. ResultsThirteen compounds were isolated and identified as: uvaol(1),ursolic aldehyde(2),4-hydroxybenzyl methyl ether(3),4-hydroxybenzyl ethyl ether(4),E-1-(4′-hydroxyphenyl)-but-1-ene-3-one(5),5,6β-epoxy-5β-sitostan-3β-ol(6),5,6α-epoxy-5α-sitostan-3β-ol(7),stigmasta-5-en-3β,7α-diol(8),daucosterol plamitate(9),glycerol 1,3-di-(9Z,12Z-octadecadienoate)(10),linoleic acid(11),daucosterol(12),β-sitoterol(13). ConclusionCompounds 1-11 were isolated from this plant for the first time. |
