Soya bean oil contains 94-95 p. c. of fatty acids (present as glycerol esters) 
of which about 15 per cent, consist of saturated acids (palmitic acid) and 
about 80 per cent, of liquid unsaturated fatty acids. The latter were found 
to consist of about 70 per cent, of oleic acid, about 24 per cent, of linolic 
acid and about 6 per cent, of linolenic acid. Samples of the oils labelled 
“ purified ” and “ unpurified ” had the following character’s respectively: — 
Sp. gr. at 15°C., 0’92(50, G'9265 ; solidif. pt. — 1T5°C.,— 12°C.; refractive index at 
40°C., 1'4<580, 1-4680 ; acid value, 5’7, 1’71 ; saponification value, 192’3, 1943; 
iodine value (Hiibl, after 18 hours' action), 13T3, 132’<57 ; Reichert-Meisel 
value, 0’75, 0'75; Polenske value, 0’78, 1’08; elaidin reaction, positive. 
Exposure of the oil for six months (in daylight) to moist air increased the 
acid value, but lowered the iodine value. Pure oxygen both in the absence 
and presence of moisture, had no influence on the iodine value. 
The phyto sterol of Soya beans. The unsaponifiable portion of Soya 
bean oil amounts to about 0’7 per cent., which is easily separated into a 
crystalline portion (about 55 per cent.) and a liquid portion (about 45 
per cent.) by means of petroleum ether (b. p. 50° C.) in which the latter is 
soluble. The crystalline portion consists of two substances (a) about 2’4 
per cent, of a phyto3terol, melting at 169°0., which has two double linkages 
and is strongly laevorotatory. It is identical with the stigmasterol isolated 
from Calaban beans by Windans and Hauth ; (b) about 97 per cent, of a 
laevorotatory phytosterol with one double linkage and melting at 139°C. The 
liquid portion of the unsaponifiable portion of Soya bean oil consists of 
unsaturated oxygenated compounds, which give the phytosterol reaction. 
Elementary analysis gave the same proportion of carbon and hydrogen as in 
the case of phytosterol (b). Experiments made to separate the phytosterol- 
like constituent of the liquid portion by 'Windans' method with digitonin 
were unsuccessful.
