Analysis of Lipid Classes and Fatty Acid Composition of Jangle Jalebi (Pithecellobium dulce L) Seed Oil.

Jangle jalebi (Pilhecellobium dulce) is one of the
important legume trees of tropical America and
cultivated throughout the plains of India. Total lipid of
Jangle jalebi seed was extracted by chloroform I
methanol (2:1, vlv) and 27.3% yellow coloured oil was
recovered. Individual lipid components were separated
by column chromatography by eluting with chloroform
(neutral lipids, 69.2%), acetone (glycolipids, 30.7%)
and methanol (phospholipids, 0.03%) and their fatty
acid composition was detennined after converting to
fatty acid methyl esters. Among the fatty acids, oleic
acid was the major unsaturated fatty acid in aU the
lipid classes. Linoleic acid was major in total, neutral
and glycolipids. Palmitic acid (16:0) was found to be
considerably higher amounts in phospholipids
compared to neutral and glycolipids. The phospholipid
fraction was found to contain phosphatidylcholine (PC)
and phosphatidylethanolamine (PE) as major
components. The seed oil of Jangle jalebi may be
considered as an attractive source for edible purpose
based on its optimum fatty acid profile.
