Trang, Nguyen Thi Quynh; Long, Dang Thanh; Hong, Hoang Thi Kim published the artcile< Phytocomponents and antioxidant activity in the methanol extract of seed lotus (Nelumbo Nucifera Gaernt.) from Viet Nam>, HPLC of Formula: 112-63-0, the main research area is phytocomponent antioxidant activity methanol extract Nelumbo Nucifera.
In this study, we determined the phytocomponents using GC-MS and evaluated antioxidant activity by a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay of the methanolic extract of six lotus varieties seed in Viet Nam (N.Nucifera). GC-MS chromatogram of the methanolic extract of six lotus varieties seed in Viet Nam showed 27 peaks which indicate the presence of 27 phytochem. constituents. The major phytochem. constituent is methyl-alpha-d-galactopyranoside (66,86-78,69%) in all lotus varieties. Antioxidant activity of liquid extract and condensed extract was found as 8.20-15.67 mg/mL and 0.850-1.286 mg/mL in comparison with IC50 of ascorbic acid (3.2μg/mL). Moreover, 50% of the DPPH scavenging ability of liquid and condensed extract differed from each other. From obtained results, the seeds of six lotus varieties in Viet Nam were found to be potential for bioactive compounds and antioxidant activity.
Research Journal of Biotechnology published new progress about Antioxidants. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, HPLC of Formula: 112-63-0.
