英文摘要	A novel arabinogalactan (MOP-1) was isolated from leaves of Moringa oleifera and was purified by macro-porous resin, DEAE-52 Cellulose and Sepharose 6B gel filtration chromatography. High performance gel permeation chromatography (HPGPC) analysis showed that the molecular weight of MOP-1 was 7.65 x 10(7) Da. Monosaccharide composition analysis indicated that sugar composition is Rha: Ara: Gal in a molar ratio of 1:7.32:12.12. Structural analysis indicated that MOP-1 has a backbone of -> 1)-beta-D-Galp-(3,4 -> with highly branched chains at 0-4 position. The branches were composed of -> 1)-beta-D-Galp-(4 ->,-> 1)-alpha-D-Galp-(2 ->, Araf-(1 ->, Galp-(1 ->. Its antioxidant activities were evaluated by DPPH radical scavenging capacity, 2,2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) radical cation scavenging capacity, and ferric-reducing antioxidant power (FRAP). The results indicated MOP-1 exhibited significant antioxidant activities. (C) 2018 Elsevier B.V. All rights reserved.
