In situ enzymatic hydrolisis was studies in the fresh and bruised palm fruid mesocarp. These fruits were stored for 5 and 30 days in a room temperature. Hyfrolisis yields contained mono and diacylglycerols in the crude plam oil were analyzed by HPLC - ELSD. The result showed that lipase in situ can hydrolize not only triacylglycerols (TAG) but also diaicylglycerols (DAG) and monoacylglycerols (MAG). The reaction increased by adding water in to the pulp palm fruit mesocrap, but the activity is very low. However, lipase in situ prefered hydrolyzed TAG acyl chain number 2 than number 1 and 3. It was proved by the highest concentration of 1,3 - DAG and specific position analysis of oil hydrolysis by using 1,3 - dipalmitoyl - 2 - oleoylglycerol (POP) and GC - FID. The analysis showed that mol ratio of palmitic and oleic acid was 1 mmol : 1,38 mmol. PSI (positional specificity index) showed value 47.09.
