The seeds were extracted with light petroleum ether (40-600 C) to yield the oil. A portion of oil in each case was hydrolysed under cold conditions with ethanolic potassium hydroxide and non-saponifiable matter and mixed acids were obtained.
The thin-1ayer.chromatography of mixed acids and their methyl esters revealed the absence of oxygenated acids. The mixed acids (a) after hydrogenation, (b) without other treatment, (c) after oxidation4 were examined by reverse phase partition chromatography ' .
The iodine values and saponification equivalents calculated from the results agree well with those measured experiment ally.
Achyranthes aspera seed oil contains 22.6% oleic and 49.4 O/ o linoleic acid amongst the unsaturated acids. The principal component amongst the saturated acids is only palmitic (18.6%). However, small amount of lauric (0.4O/o), m ristic (1.2%), stearic (4.4O/o), arachidic (1.6%) and behenic $.80/0) acids are reported in the present investigation.
(0.6%),arachidic (ld%),and behenic (O.G%).The unsaturated acids are only oleic (1 7 5 %) and linoleic (59.1 %) .
The study on Aberia cafia seed oil was undertaken with a view that this species might contain some unusual fatty acids like hydnocarpic acid which is found in Flacourtiaceae family6. However, no unusual acid has been noticed in this species. The fatty oil contains palmitic acid (25.g0/4 as only the major component amongst the saturated acids with smaller amounts of lauric(02%),myristic (0.9O/o),stearic (3.9%), arachidic (1.2%) and behenic (0.5%) acids. The fatty oil also contains linoleic (48.10/0) and oleic (19.3%
