Abstract:
An investigation of the petroleum ether extract from Ixeris chinensis Nakai has led to the isolation of a new compound, 3-O-acetyl-22,28-cyclobauer-7-en-3β-ol (1), together with four known compounds which have been isolated from this plant for the first time, namely taraxast-20-en-3β-ol (2), 3-O-acetyl-taraxast-20-en-3β-ol (3), taraxast-20(30)-en-3β-ol (4), and 3-O-acetyl-taraxast-20(30)- en-3β-ol (5). The structures of the isolated compounds have been elucidated on the basis of spectroscopic methods including UV, IR, ESI-MS, 1D NMR, 2D NMR techniques, and by comparison with data reported in the literature. All compounds have been evaluated for their activity against various bacteria and shown to give good results
