   Subscribe/Renew Journal


The kernel (48.8% of seeds) of Olea dioica Roxb received from Nasik (Maharashtra) yielded 24.54% of a fixed oil' having refractive index' 1.4369/25°C; acid value' 42.35' saponification value' 208.97 and Iodine value' 87.67. Gas-liquid chromatographic analysis of the mixed acids has shown the fatty acid composition as palmitic' 24.10%; arachidic' 7.93%; behenic' 0.77%; Oleic' 41.45%; linoleic' 15.04% and others (unidentified acids), 10.71%. The seed oil may be recommended for edible use after ascertaining its non-toxic nature.

Abstract


The kernel (48.8% of seeds) of Olea dioica Roxb received from Nasik (Maharashtra) yielded 24.54% of a fixed oil' having refractive index' 1.4369/25°C; acid value' 42.35' saponification value' 208.97 and Iodine value' 87.67. Gas-liquid chromatographic analysis of the mixed acids has shown the fatty acid composition as palmitic' 24.10%; arachidic' 7.93%; behenic' 0.77%; Oleic' 41.45%; linoleic' 15.04% and others (unidentified acids), 10.71%. The seed oil may be recommended for edible use after ascertaining its non-toxic nature.
