| Abstract: |
| To investigate the chemical constituents of Ainsliaea glabra,several chromatographies including Silica gel column chromatography and Sephadex LH-20 gel column chromatography were applied to the isolation and purification of chemical constituents. The structures were identified on the basis of chemical evidence and spectral data.The results showed that seventeen compounds were isolated from A. glabra and they were identified as taraxasteryl acetate(1),dotriacont-1-ene(2),β-sitosterol(3),chrysophanol(4),lupenyl palmitate(5),methyl linolenate(6),linoleic acid(7),phytol(8),stigmast-4-en-3-one(9),phytenal(10),betulinic acid(11),(9Z,11E)-13-oxo-9,11-ocatadecadienoic acid(12),E-7,9-diene-11-methenyl palmitic acid(13),taraxinic acid(14),3β-hydroxy-cholesta-5-ene(15),epoxylycopaene(16),28-O-laurylbetulin(17). Compounds 1-17 were obtained from this herb for the first time. |
