A Study of Coconut (Cocos Nucifera L.) Phosphatidylcholine Species

Abstract

Coconut (Cocos nucifera L.) phosphatidylcholines, or CocoPCs species are studied in this paper. CocoPCs is fractionated from coconut phospholipids (CocoPLs) using methanol eluent in silica column chromatography. Analysis of the CocoPCs, by FTIR, GCMS and LCMS, reveals that among the isolated CocoPCs species are 16:0/18:0-PC with m/z 763 at Rf 6.02 and 18:1-LysoPC with m/z 522 at Rf 4.93. The composition of CocoPCs fatty acid chain residues are Dodecanoic acid (C12:0), Tetradecanoic acid (C14:0), 9-Hexadecenoic acid (C16:1), Hexadecanoic acid (C16:0), 9,12-Octadecadienoic acid (Z,Z) (C18:2), 9-Octadecenoic acid (C18:1) and Octadecanoic acid (C18:0). The CocoPCs content is 6.317% of 100 mg CocoPLs.
