摘      要：Four compounds were isolated from Torricellia angulata var intermedia(Harms.) Hu (Torricelliaceae) by column chromatography accompanied synthetic structure modification method and two new polyacetylene compounds with a chiral carbon center were included whose absolute configurations were determined by the recently developed expended Mosher’s method.
