Molecular species of glycolipid and anti-inflammation activity of lipid fractions in the green algae Halimeda incrassata Lamx. collected from Truong Sa, Viet Nam

Abstract

In this study, 40 glycolipid molecular forms have been identified belonging to 3 groups of MGDG (12), DGDG (11), SQDG (17). The MGDG molecular forms count for a high concentration in the PUFA fatty acid component such as C18:2, 18:3, 20:4. The DGDG forms mainly contain saturated fatty acids and 1 double-bonded while the SQDG forms have the intertwine between saturated fatty acids and super long and long-chain HUFA fatty acids (over 20C and 4 double bonds) such as C20:4, 20:5 and 22:6. Results of biological activity test for three lipid fractions of Halimeda incrassata Lamx. seaweed have showed that they have anti-inflammatory activities from 32.57±5.75 to 41.66±1.95 µg/ml., of which the highest is the polar lipid fraction. This showed that this is a potential source to continue screening for bioactive compositions to apply on the medicine and pharmacy.
