A feruloylated acylglycerol isolated from Wikstroemia pilosa and its distribution in ten plants of Wikstroemia species

Feruloylated acylglycerols (FAGs) have recently garnered a lot of interest as water-oil-miscible ferulic acid derivatives. A novel FAG derivate, 1-feruloyl-3-hexadecanoylglycerol (1), was isolated from Wikstroemia pilosa and its structure was elucidated from extensive physiochemical and spectroscopic analysis. Since the limited distribution of FAGs in plant species has been reported, a high-resolution accurate mass (HRAM) LC-MS quantitative analysis was carried out to determine the contents of 1 in ten plants of Wikstroemia species. As a result, compound 1 was detected in all species at contents of 1.29-50.96 mg/kg dry weight and W. dolichantha contained 1 at the highest content.
