ADVISER: Dr. Teresita M. Espino

The effects of various extraction methods and different varieties of coconut on the ii-sitosterol content in coconut oil were investigated. The different methods included the traditional method ("latik" method), wet method (without enzymes) and wet method (with enzymes). Results showed that coconut variety and extraction method used affected the percent recovery of the oil. The highest percent recovery (75.18%) was obtained for the Laguna Tall variety and the wet method (with enzymes) proved to be most effective (61.87%). High percent oil recoveries were also obtained for Malayan Red Dwarf and Hijo Tall hybrid (60.71%), Malayan Red Dwarf and Tagnanan Tall hybrid (52.80%) using the wet process (with enzymes) as compared to the traditional process ("latik" method) and wet process (without enzymes) except for Malayan Red Dwarf and Baybay Tall hybrid in which the traditional method ("latik" method) and wet process (with enzymes) had almost the same percent oil yields.

Thin layer chromatography of the coconut oil samples showed the presence of (3- sitosterol by comparing the R., value of standard 13-sitosterol with those of coconut oil samples from different varieties. Generally, the method of extraction used did not affect the concentration of the said sterol in all varieties studied based on the size and color intensity of the 13-sitosterol spot.
