ResumoEsters 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)-O5-furanoyl-O5-deacetyl-7-deoxo-evonine, 7-(acetyloxy)-O11-furanoyl-O11-deacetyl-7-deoxo-evonine and 7-(acetyloxy)-O11-benzoyl-O11-deacetyl-7-deoxo-evonine by spectroscopic means. This structural elucidation indicated that the structure of the known compound should be reversed.
