Identification of fatty acid esters and hydrocarbon derivatives from Cyrtocarpa procera Kunth by GC–MS

Abstract

Extracts obtained from Cyrtocarpa procera Kunth were evaluated to determine their toxicity on Artemia salina Leach. All the extracts showed a significant activity. Bioguided fractionation of these extracts led to the isolation of β-sitosterol (1) and the identification of 1,3-propyl-dipentadecanoate (2), 3-hydroxypropyl-9-octadecenoate (3), pentadecylbenzene (4), eicosylbenzene (5), docosane (6), heptacosane (7), dotriacontane (8) and 2,6,10-trimethyltetradecane (9) by GC–MS.
