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