Chemical investigation of Acacia seed oils

The seed oils of Acacia mollissima, A. torta, A. lenticularis and A. nilotica are found to contain 6.2, 5.3, 4.7 and 3.1%, respectively, cor-onaric acid in addition to other fatty acids. The structure of coronaric acid was established by chemical and physical methods using Chrysanthemum coronarium seed oil and its derived coronaric acid as the reference sample.
