Studies on bio-efficacy of 2, 4-D Ethyl Ester 80% EC in maize and its effect on succeeding crop lentil

Abstract

The present study was carried out to examine the yield of crude oil extracted from the dried papaya seeds by solvent extraction method. The physicochemical properties, fatty acids, tocopherols and phenolic composition of crude oil extracted from papaya (Carica papaya Linn.) were assessed. From the present study carried out, the yield of the papaya seed oil is 25.6%. The physicochemical properties of Papaya seed oil were: acid value (2.805mg/g), saponification value(95.37mg KOH/g), iodine number(63.1), peroxide value(5.27mEq/kg), phenols(118.97µg/mL), tocopherols (51.77µg/g), Unsaponification value(1.318%), pH(5.6), density(0.94g/mL), moisture content of oil (0.210%), specific gravity(0.921). The values of proximate of dried papaya seed powder were: low moisture content(0.02%), high ash content(9%), high protein content(32.97g/kg), relatively high crude fibre content(18.83%), low carbohydrate content(895.485µg/g)and also the fatty acids present in the papaya seed oil were noticed.
