Fatty Acid, Tocopherol, Sterol Compositions and Antioxidant Activity of Three Garcinia Seed Oils

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 IC50 value of 6.34± 0.43 μg /mL or EC50 = 11.71 ± 0.22 μg /mL.
