摘要：

A new daucane ester, lasidiol p-methoxybenzoate [2], and the known guaianolide ziniolide [1] were isolated from the roots of Xanthium catharticum. The MeOH extract of the aerial part afforded three new xanthanolides, 11-alpha, 13-dihydro-8-epi-xanthatin [5] and the corresponding 1-beta,5-beta- and 1-alpha,5-alpha-epoxides, 7 and 8, respectively. The structures were elucidated by highfield nmr techniques. Cytotoxic and antitumor activities were found for ziniolide [1].
