Presence of Phytol, a Precursor of Vitamin E in Chaetomorpha Antinnina

Abstract

Phytol, a precursor of vitamin E was identified from green algae Chaetomorpha antinnina collected from Chullickal, Kochi Kerala coast, using GC-MS. Phytol is an acyclic diterpene alcohol that can be used as a precursor for the manufacture of synthetic forms of vitamin E and vitamin K1. The compound 3,7,11,15-tetramethylhexadec-2-en-1-ol also known as phytol  which exist  naturally only in single isomeric form having molecular formula C20H40O and molecular mass 296. From the total ion chromatogram more than twenty peaks were observed, the mass spectrum of the peak at Rt 21.53 was resolved and the major fragmentations were noted. Major fragmentation were m/z 71 the base peak, m/z 296 the molecular ion peak, m/z 43, m/z 57, m/z 81, m/z 95, and m/z 123. It was found that there are some other compounds apart from this identified phytol which are more complicated in structure and cannot be characterised using GC-MS. Phytol is reported to have both antimicrobial and anticancer activities. The green algae Chaetomorpha antinnina can be proposed to be a good natural source for production of phytol.
