Fatty Acid and Carotenoid Composition of Gac (Momordica cochinchinensis Spreng) Fruit
In this study, we analyzed fatty acid and carotenoid composition of fruit tissues, including seed (which are surrounded by a bright red, oily aril) of Momordica cochinchinensis Spreng, known as gac in Vietnam. Carotenoid content was analyzed by reversed-phase HPLC, using a C30 column and a method se...

Zusammenfassung: | In this study, we analyzed fatty acid and carotenoid composition of fruit tissues, including seed (which are surrounded by a bright red, oily aril) of Momordica cochinchinensis Spreng, known as gac in Vietnam. Carotenoid content was analyzed by reversed-phase HPLC, using a C30 column and a method separating cis- and trans-isomers of the major carotenoids in this fruit. Mean values obtained in aril tissues were 1342 μg trans-, 204 μg cis-, and 2227 μg total lycopene; 597 μg trans-, 39 μg cis-, and 718 μg total β-carotene; and 107 μg α-carotene/g FW. Mesocarp contained 11 μg trans-, 5 μg cis-β-carotene/g FW, trace amounts of α-carotene, and no lycopene. Gac aril contained 22% fatty acids by weight, composed of 32% oleic, 29% palmitic, and 28% linoleic acids. Seeds contained primarily stearic acid (60.5%), smaller amounts of linoleic (20%), oleic (9%), and palmitic (5−6%) acids, and trace amounts of arachidic, cis-vaccenic, linolenic, and palmitoleic, eicosa-11-enoic acids, and eicosa-13-enoic (in one fruit only) acids. Keywords: Momordica cochinchinensis Spreng; fatty acids; carotenoids; HPLC; lycopene; β-carotene; aril; mesocarp; seed; oil. |
