Analysis of the fixed oil and the unsaponifiable matter from the seeds of Feronia limonia Linn

Abstract

The proximate anal. on the seeds of F. limonia revealed the presence of moisture (5.896%), ash (6.822%), acid insol. ash (1.3202%), sulfated ash (4.588%), alc. sol. extractive (6.2810%), and water sol. extractive (10.1022%). The powd. seeds were treated with various nonpolar to polar solvents and the extractives tested for the common plant constituents. Fixed oil (12.5%) was extd. from the seeds and crude protein (12%) and carbohydrates (0.8250% as glucose) from the defatted seeds. The fixed oil was found to contain palmitic (15.2%), oleic (43.4%), linoleic (20.4%), and linolenic (20.6%) acid besides traces of palmitoleic and stearic acid. The unsaponifiable matter (0.8% of the total oil) contained β-sitosterol, β-amyrin, lupeol, and stigmasterol.
