Abstract

Tabernaemontana divaricata Linn oil was extracted and transesterification was carried out using methanol as the solvent in presence of a catalyst to produce biodiesel. Fatty acid methyl esters in biodiesel prepared from Tabernaemontana divaricata seed oil was analyzed by IR, NMR and GC-MS. The composition of the biodiesel is estimated as 27.0 wt.% methyl palmitate (C16:0), 10.54 wt.% methyl linoleate (C18:2), 56.23 wt.% methyl oleate (C18:1) and 6.20 wt.% methyl stearate (C18:0).
