Chemical examination of nageswar (Mesua ferrea) nut oil and meal

Abstract

The nuts had an av. wt. of 2.87 g., av. kernel 63.3, and av. shell 36.4%. The yield of oil by petr. ether extn. was 70%, based on the wt. of the kernel. The crude and the purified and refined oils had the following characteristics, resp.: color (Lovibond 1 cm.) 28 Y + 5.6 R, 0.8 Y + 0.2 R; odor strongly disagreeable, faint; taste bitter, bland; d34 0.9202, d31 0.9604; n32.5 1.4721, n31 1.4651; acid value 8.8, 0.5; sapon. value 203.2, 197.7; I value (Wijs) 81.1, 76.6. The defatted nut meal was exhaustively extd. with hot EtOH giving a white, light powder having an agreeable taste and flavor. The processed meal contained H2O 7.1, N 5.1 (equiv. to 34.3% protein), and ash 7.05%. The ash contained Fe+++ 0.64 and P2O5 39.3%. Na, K, and Ca were also found in the ash, but no data are given. The EtOH ext. of the defatted meal yielded 2.3% sucrose
