Abstract

Experimental Section General procedures, instrumentation, and the collection, extraction and initial chromatographic separation work with Briareum polyanthes have been described previously. 2b Brianthein W. The CC1,-soluble extracts of B. polyanthes, 3.755 g, 2b were permeated through Sephadex LH-20 with CHzC12-hexane (41). Fraction 5, 1.2009 g, was permeated through Bio-Beads S-X4 with hexane-CHzClz-EtOAc (44: l). Fraction 5, 382 mg ...
