Abstract
Three phase partitioning has been evaluated for extraction of oil from Jatropha curcas L.
seeds.
This process consisted of
simultaneous addition of t-butanol (1:1, v/v) and 30% (w/v) ammonium sulphate to the slurry prepared from Jatropha seed
kernels.
Combination of sonication and enzyme treatment with a commercial preparation of fungal proteases at pH 9, led to 97%
oil yield within 2 h.

Introduction
Recently, we have described a new approach for
extraction of oil from plant materials, in general, and
soybean in particular (Sharma et al.
, 2002a).
In this approach, called three phas
