1, 3-Dicapryloyl-2-linoleoylglycerol (1), a novel triglyceride, was isolated from berries of Hippophae rhamnoides. The structure was elucidated on the basis of MS, 1D and 2D NMR experiments including HMQC and HMBC. The metal chelating, free radical scavenging, and lipid peroxidation inhibiting properties of the compound were also estimated with particular reference to radiation protection. In case of metal chelation and superoxide ion scavenging, 1 showed maximum inhibition at 50μg/ml (11%) and 100μg/ml (55%), respectively, whereas in lipid peroxidation, 1 showed maximum inhibition (57%) at 2mg/ml as compared to quercetin as a control.
