Conclusion
This study aimed to extract bioactive compound from oil palm fruit after 0-240 h of harvesting. In
addition, lipase from oil palm was also partitioned and analyzed. Oil palm fruits after 0-240 h of harvesting
were firstly extracted by six different solvent 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. 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 phytochemical content 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), carbohydrate (470 mg/g DW) and protein (2.4 mg/g
DW). Tocopherol, tocotrienol and carotene from oil palm fruit after 0-240 h of harvesting were also
evaluated. The highest tocopherol (850 mg/kg), tocotrienol (800 mg/kg) and carotene (790 mg/kg) was
obtained after 0 h of harvesting. However, the highest lipase activity was obtained from Tris-HCl buffer (pH
8.0). The highest lipase activity (0.4 U/mL) with 0.1 U and 1.38 U/mg protein was achieved from oil fruit
after 120 h of harvesting.
