Part III.] Gopal Rau and Simonsen : OiU and Fats from seeds. 11 
Fractions III and IV were identified as pure stearic acid and frac- 
tions VII and VIII as pure palmitic acid, whilst Fractions V and VI 
were apparently a mixture of these two acids. The nature of the acid 
present in Fraction I could not be definitely determined as it was only 
obtained in very small quantity. It was a saturated acid and gave on 
analysis the following figures ; — 
0 0885 gave 0 2526 COj and 0 0981 H^O, 0=77-8, H=12-3. 
C22H44O2 requires 0=77-6, H=12-9 per cent. 
It would therefore appear possible that this acid consisted of 
impure behenic acid which is stated to melt at 8-1° and has an 
equivalent of 310. 
Identification of the Liquid Acids. 
The crude liquid acid had an iodine value of 82 and on distillation 
under diminished pressure (100mm.) the following fractions were 
obtained : —

From a consideration of the iodine values the acid would appear to 
consist solely of oleic acid and attempts to prepare a solid bromo acid 
were unsuccessful. The barium salts prepared from Fractions II and 
III gave on analysis the following figures : — 
I. 0-2309 gave 0-0756 BaSOi Ba=19-3. 
II. 0-2264 gave 0 076 BaSOi Ba=19-7. 
C36 H66O4 Ba requires Ba=19-6 per cent. 
These analyses which were made with the unpurified barium salts, 
confirm the absence of acids other than oleic acid. 
Summary. 
The seeds from Mimusops Elengi have been found to yield on ex- 
traction 16 per cent, of an oil. 
2. The acids present in the oil were shown to be stearic, palmitic 
and oleic acids together vnth a small quantity of another saturated 
acid which was not identified but which was possibly behenic acid.
