Abstract

Three species of Phragmipedium (Orchidaceae), P. calurum, P. longifolium, and P. hybrid (var. Sorcerer's Apprentice), were analyzed by high-throughput isolation. A total of 12 new (1-4, 6-10, 12, 14, 16) and five known compounds (5, 11, 13, 15, 17) were isolated from these orchids. Compounds 1-8 are stilbenes substituted with one or two 4-hydroxybenzyl moieties. This type of substitution on stilbenes is unusual and has been reported only twice. The structure elucidation was based on spectroscopic analysis.
