Abstract
Oil palm fruits after 0-240 h of harvesting were firstly extracted by six different solvents including
acetone, ethanol, Tris-HCl buffer (pH 8), methanol, chloroform and hexane. The highest bioactive
compounds (10.82 g, 5.41% yield) were obtained from methanol extraction. Oil palm fruit after 0 h of
harvesting contained moisture (30.24%), protein (5.12%), lipid (52.94 g oil/g oil palm fruit and ash (1.84%).
In addition, other bioactive compound were yielded the highest content after 0 h of harvesting including
alkaloid (1.6 mg/g DW), saponin (3.5 mg/g DW), flavonoid (0.3 mg/g DW), phenolic (0.3 mg/g DW), tannin (3.5
mg/g DW),. tocopherol (850 mg/kg), tocotrienol (800 mg/kg) and carotene (790 mg/kg). Besides, it also
contained carbohydrate (470 mg/g DW) and protein (2.4 mg/g DW). . The highest lipase activity (0.4 U/mL)
was obtained from Tris-HCl buffer (pH 8.0).
