Abstract

The seed of P. communis, known locally as alubukhara, contained kernel 20, H2O 13.9, and oil 39.11%. The oil extd. with petr. ether had the following characteristics: d18.5 0.912, viscosity (60°, Redwood No. 1 viscometer) 96 sec., n13.5 1.471, acid value 1.25, sapon. value 191.8, sapon. equiv. 292.5, acetyl value 3.02, I value (Wijs) 90.73, hexabromide value 0, unsaponifiable 1.56, and satd. fatty acids (modified Bertram method (cf. C.A. 21, 2391, 2994) 14.51%. The compn. of the cake free from oil was: proteins 37.5, crude fiber 2.4, carbohydrates 40.88, and ash 5.32%. The ash contained 7.25% phosphates (as P2O5), SiO2, and salts of Na, K, Mg, and Al. The oil contained the following fatty acids: lauric 0.61, myristic 3.08, palmitic 0.52, stearic 4.39, arachidic 6.01, oleic 64.39, and linoleic 19.44%. Com. exploitation of the oil is recommended.
