“…In the present study, it was observed that the acetyl group on the allose unit was ineffective on antioxidant activity. Furthermore, the antioxidant activity of compound 7 has been reported in previous studies (Aldini et al, 2006;Siciliano et al, 2005). Thus, the presence of ortho-hydroxyl groups on phenolic moieties is responsible for the remarkable antioxidant activity, as previously reported for flavonoids (Rios et al, 1992) and for phenylethanoid glycosides (Heilmann et al, 2000).…”

“…Red blood cells (RBC) were isolated from male Wistar rats and suspended in balanced phosphate buffered saline (PBS) to obtain a 1% RBC suspension [28]. Aliquots (3.5 ml) were incubated at 37°C for 210 min in the presence of 50 μM Cumene hydroperoxide (CuOOH, dissolved in ethanol) and the cellular integrity determined turbidimetrically at 710 nm at 30 min intervals [28].…”

Antioxidant activity of the aerial part and bulbs of Allium paradoxum was investigated by eight in vitro assay systems. Extracts showed good antioxidant activity. IC 50 for 1,1-diphenyl-2-picryl hydrazyl radical-scavenging activity was 890.9±43.2 and 984.9±33.5 µg/ml for the aerial part and bulbs, respectively. The aerial parts have better reducing power than bulb extracts but not comparable with Vitamin C (P<0.001). Extracts showed weak Fe 2+ chelating ability, the IC 50 being 959±47 and 530±24 µg/ml for bulbs and aerial parts, respectively. Both tested extracts exhibited good hydrogen peroxide scavenging in a concentration dependent manner. They exhibited good antioxidant activity against the hemoglobin-induced linoleic acid system that was comparable with vitamin C (P<0.01). They showed good activity against cumene hydro peroxide induced hemolysis in RBCs. In addition, they possessed antihemolytic activity. The extract from aerial parts had significantly higher total phenol and flavonoid content than did bulbs. Amounts of eight elements (Cu, Mn, Zn, Fe, Ni, Pb, Cd and Cr) were also determined in the bulb and aerial part using atomic absorption spectroscopy. They contained higher Fe and Mn contents than other elements. © Versita Sp. z o.o.
