Isolation and structure elucidation of a new glyceride from seeds of Wrightia tinctoria found in Jharkhand region of India

Abstract

A glyceride compound was isolated from the seeds of Wrightia tinctoria (Apocynaceae). Their structure was established, on the basis of spectroscopic data. The ethanolic extract of Wrightia tinctoria seeds packed in silica column and column was eluted with 10%, 20%, 30%, 40%, 50% petroleum ether and chloroform mixture solvents. The F6 fraction of 20% elutes assigned as Glyceryl-1-linoleryl-2-achidyl-3-docos-9```, 12```-dienoate. It was found to be pale yellow color liquid; its structure was assigned on the basis of IR, 1H NMR, 13CNMR and MS analysis.
