Abstract: The fatty acid, tocopherol, and sterol contents of the extracted seed oils from three Garcinia species, including G. hanburyi Hook. f., G. multiflora Champ. ex Benth., and G. gaudichaudii Planch. & Triana, were analyzed. The results showed that the Garcinia seeds contained a high amount of oil (16.28–29.91%). The major monounsaturated and saturated fatty acids were oleic acid (82.97 % in G. multiflora and 45.37 % in G. hanburyi) and stearic acid (58.87 % in G. gaudichaudii and 50.12 % in G. hanburyi). In addition, three extracted oils exhibited moderate antioxidant activity with G. hanburyi displayed the strongest activity with IC 50 value of 6.34± 0.43 μg /mL or EC 50 = 11.71 ± 0.22 μg /mL.
