Bitter Gourd Seed (BGS) oil of two varieties were evaluated for physicochemical composition, antimicrobial and hemolytic activities however BGS residue was appraised for proximate composition, mineral contents and the efficacy of extracting solvents; ethanol, 80% ethanol and water; extraction techniques; shaking, reflux and ultrasound on antioxidant activity of BGS extract was evaluated. Significantly (P<0.05) higher oil and protein content was observed in the BGS-1 (40.8 and 19.2% respectively… Expand
