Garcinia benthami Pierre (syn Garcinia ferrea Pierre) is also known as Bunog by the Cuyunin tribe and Tagbanua in Palawan Philippines. The compounds present in the dichloromethane (DCM) extract of roots, fruit peels, fruit seeds, fruit fleshes, stem barks, leaves and flowers were isolated by using normal phase chromatography and identified by NMR spectroscopic technique. Triacylglycerol (TAG) was isolated in extract of roots, stem barks, flesh and seed of the fruits. Squalene was isolated from roots, fruit peels, stem barks and fruit fleshes extract. Caryophyllene (CAR) was isolated from fruit peels and leaves extract. Methyl (24E)-3 {u1D6FC} ,9 {u1D6FC}, 23-trihydroxy-17,14-friedolanosta-14,24-dien-26-oate was isolated from fruit peels, leaves and flowers extract. While the mixture of {u1D6FD}-sitosterol and stigmasterol was obtained from flowers and fruit seeds extract. Chlorophyll a and {u1D6FC} carotene were only isolated from the leaves and friedelin was only isolated from stem barks extract. A new triterpene (24E)-23 acetoxy-3{u1D6FC}-hydroxylanostane-9(11), 16, 24-trien-26- oic acid were isolated from the roots extract and obtained as part of the mixture with (22Z, 24E)-9 {u1D6FC} -hydroxy-3-oxo-17,14-friedolanosta-14,22-24-trien-26-oic acid and a new triterpene (24E)-9 {u1D6FC}-hydroxy-3-oxo-17,14-friedolanosta-14, 24-dien-26-oic acid from the fruit peels extract. Another mixture of triterpenes, (22Z, 24E)-9{u1D6FC}-hydroxy-3-oxo-17,14- friedolanosta-14,22-24-trien-26-oic acid and Methyl (24E)-9,23-dihydroxy-3-oxo-17,14- friedolanostan-14,24-dien-26-oate (another new triterpene) was obtained from the stem barks.
