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

Abstract

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.

Seed Fatty Acid Composition and Germination Studies in Garcinia dhanikhariensis S.K. Srivastava (Clusiaceae): A Novel Tropical Fruit Species from Bay Islands, India

“…f. (53.11%) and G. gaudichaudii Planch. & Triana (61.15%) (Phuong et al, 2018). Of the unsaturated fatty acids observed, amounts of MUFAs were higher than that of PUFAs, which is in line with that found in G. andamanica (Bohra et al, 2021), G. multiflora Champ.…”

“…In general, stearic acid is present in lesser frequencies in fats derived from plant sources. However, this compound has been reported to be present to a tune of about 28-45% in industrially important cocoa and shea butters (Beare-Rogers et al, 2001); while G. gaudichaudii (50.12%), G. hanburyi (58.87%) and G. andamanica (11.83%) are other species containing stearic acid (Bohra et al, 2021;Phuong et al, 2018). Stearic acid is a common constituent in the manufacture of detergents, soaps, shaving creams and similar cosmetic products (Parthasarathy and Nandakishore, 2014).…”

“…multiflora, G. hanburyi, G. gummi-gutta, G. morella (Gaertn.) Desr., G. indica, G. xanthochymus and G. mangostana (Ajayi et al, 2007;Bohra et al, 2021;Choppa et al, 2015;Patil et al, 2016;Phuong et al, 2018). Vietnamese Garcinia species rich in oleic acid have been identified as healthy oil sources for commercial utilization (Phuong et al, 2018).…”

“…Polyphenolic compounds are involved in neutralizing free radicals, modulating the enzymatic activity, and decomposing peroxide mechanisms to produce antioxidant activities [ 47 ]. Sterols are reported to be of great benefit to human health due to their antioxidant activities [ 48 ]. Vitamin C enhances the antioxidant capacity of the body mainly by scavenging hydroxyl radicals and cutting off the chain reaction.…”

Antioxidant and Cytotoxic Activities of Usnea barbata (L.) F.H. Wigg. Dry Extracts in Different Solvents

“…It is known that ROS and RNS are permanently generated in plants as a result of aerobic metabolism; some of these reactive species have high toxicity, and the numerous cellular mechanisms rapidly neutralize them [ 11 ]. Various plant extracts [ 12 ] and isolated natural compounds [ 13 ] have antioxidant effects: vitamins [ 14 ], flavonoids [ 15 ], polyphenols [ 16 ], sterols [ 17 ], and polysaccharides [ 18 ]. Lichens are a significant source of antioxidants [ 19 ]; the Parmeliaceae family [ 20 ] with the Usnea genus, are known due to their antioxidant metabolites [ 21 ].…”
