Abstract
|
|
|
The antioxidant activities and total phenolics of four Rosaceae species Pourthiaea villosa (Thunb.) Decne, Sorbus
commixta Hedlund, Sorbaria sorbifolia var. stellipila Maxim and Pyrus pyrifolia (Burm.f.) Nakai were determined.
Phenolic content (polyphenol and flavonoid), radical scavenging activities [2,2-Diphenyl-1-picrylhydrazyl (DPPH) and
2,2-azino-bis (3-ethylnezthiazoline-6-sulfoic acid) (ABTS)] and ferrous ion chelating effect were evaluated. Total
polyphenol and flavonoid contents were highest in Pourthiaea villosa (Thunb.) Decne and lowest in Pyrus pyrifolia
(Burm.f.) Nakai. Phenolic contents of Pourthiaea villosa (Thunb.) Decne was 331.45±7.78 and 90.4±3.5 mg·g-1. DPPH
and ABTS radical scavenging activities were found to be lowest in Sorbus commixta Hedlund whereas Sorbaria
sorbifolia var. stellipila Maxim and Pourthiaea villosa (Thunb.) Decne showed relatively good DPPH and ABTS radical
scavenging activities. Ferrous ion chelating effect was highest in Pyrus pyrifolia (Burm.f.) Nakai (1.05±0.04 mg·ml-1)
and lowest in Sorbus commixta Hundlund (4.22±0.71 mg·ml-1).
