Proteins of the Seeds of some Indian Forest Trees <I>Cassia Tora, Terminalia Belerica and Duabanga Sonneratioides</I>

Abstract

The chief protein of the seeds of Terminalia belerica and Duabanga sonneratioides is globular in nature. The seeds of Cassia tara are rich in both albumins and globulins. The proteins have been analysed for their Van Slyke nitrogen distribution and tyrosine and tryptophane contents. The Terminalia belerica and Cassia tora globulins while comparing favourably with the globulins of Santalam album, are rather poor in tryptophane content as compared with Dolichosin but are superior to Cajanin. The Duabanga sonneratioides globulin is poor in cystine also. The albumins from Terminalia belerica and Cassia tora are essentially inferior to the albumin from Cajanus indicus in their cystine contents.
