Antioxidant activity of different extracts of lotus (Nelumbo nuficera Gaertn) rhizome by gradient solvent extraction
نویسندگان
چکیده
In vitro antioxidant activity of extracts lotus rhizome with different solvent by gradient extraction was determined. The yield and total phenolic content were 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) radical scavenging assay β-carotene-linoleic acid conducted to assess the extracts. Results showed that butanol extract highest. order in as follows: water < petroleum ether chloroform ethyl acetate extract, same DPPH activity. significantly correlated (R2 = 0.9363). All extracts, except too poor activity, obvious against acid, lower than others. There no significant correlation between =0.1995).

Antioxidant activities of various extracts of lotus (Nelumbo nuficera Gaertn) rhizome.
Lotus rhizome powder was extracted with solvents of different polarities. Antioxidant activities of the extracts were evaluated by a 2, 2'-diphenylpicrylhydrazyl (DPPH) assay and a beta-carotene bleaching assay, and compared with that of butylated hydroxyanisole (BHA) and ascorbic acid. Methanol showed the highest extract yield among all of solvents. Although acetone extract had the highest tot...
متن کاملImmunoregulatory and anti-HIV-1 enzyme activities of antioxidant components from lotus (Nelumbo nucifera Gaertn.) rhizome.
In the present study, two antioxidant micromolecular components (L2f-2 and L2f-3) and an antioxidant macromolecular component LB2 were extracted from lotus (Nelumbo nucifera Gaertn.) rhizomes. MS, FTIR (Fourier-transform IR) spectroscopy and NMR were used to identify these compounds. L2f-2 was (+/-)-gallocatechin, L2f-3 was (-)-catechin and LB2 was a polysaccharide-protein complex with a molecu...
