Polygala virgata seed oil—A new source of acetotriglycerides

Abstract

The seed oil ofPolygala virgata (family Polygalaceae) contains 74% of monoacetotriglycerides, the first found in nature with the acetate group in position 2 ofsn-glycerol. Naturally occurring triglycerides characterized previously all have the acetate at position 3. The configuration of the acetoglyceride fromP. virgata was established by a combination of thin layer chromatography, optical rotatory dispersion, and nuclear magnetic resonance.
