Free and glucosyloxy acetophenones from Pancratium biflorum

Abstract

Two new dimethoxy-acetophenone-O-glucosides and the known 2,4,6-trimethoxyacetophenone were isolated from the flowering bulbs and pseudo-stem fluid of Pancratium biflorum. The structures of the new compounds were established as 4,6-dimethoxyacetophenone-2-O-β-d-glucoside and 2,6-dimethoxyacetophenone-4-O-β-d-glucoside on the basis of chemical transformation, comprehensive spectroscopic analyses, and synthesis of the aglucones. The biological activity profile of the glucosides and their aglucones is also appraised. © 1983.
