摘要：

Esters of three new (hyponines A-C) and four known sesquiterpene polyalcohol esters have been isolated from the root bark of Tripterygium hypoglaucum. The structures of the new compounds were elucidated at 7-(acetyloxy)-O-5-furanoyl-O-5-deacetyl-7-deoxo-evonine, 7-(acetyloxy)-O-11-furanoyl-O-11-deacetyl-7-deoxo-evonine and 7-(acetyloxy)-O-11-benzoyl-O-11-deacetyl-7 by spectroscopic means. This structural elucidation indicated that the structure of the known compound should be reversed. (C) 1997 Elsevier Science Ltd.
