Dorsamin-A’s, Glycerolipids Carrying a Dehydrophenylalanine Ester Moiety from the Seed-Eating Larvae of the Bruchid Beetle Bruchidius dorsalis
摘要:
Using a TLC autographic assay for radical-scavenging activity with the ABTS radical, the presence of lipophilic antioxidants in the larvae of the wild bruchid seed beetle Bruchidius dorsalis was detected. Assay-guided fractionation of the CHCl3-soluble fraction of the larvae resulted in the isolation of new glycerolipids, designated dorsamin-A763, -A737, -A765, -A739, and -A767, comprising 1,2-diacyl-sn-glycero-3-dehydrophenylalanine ester structural units. The ABTS radical scavenging activity of the dorsamin-A's was comparable with or stronger than that of Trolox.
