3-Hydroxy Fatty Acids from the Flowers of Hypericum lysimachioides var. lysimachioides

摘要

Fatty acid methyl esters in the leaves and flowers of Hypericum lysimachioides var.lysimachioides(Guttiferae)were analyzed by gas chrornatography and gas chromatography-mass spectrometry.The flowers of H.lysimachioides var.lysimachioides produced unusual 3-hydroxy fatty acids [3-hydroxy- tctradecanoic acid(3-OH-C14:0)and 3-hydroxy-octadecanoic acid(3-OH-C18:0)],along with other normal fatty acids.Major components were linolenic and palmitic acids for both leaves and flowers.
