Tóm tắt
Methanol aqueous extracts of 100 plants were screened for anti‐oxidative activity using Fenton's reagent/ethyl linoleate system and for free radical scavenging activity using the 1,1‐diphenyl‐2‐picryl hydrazyl free radical generating system. The results suggest that 14 plants ‐ Alpinia officinarum, Areca catechu, Brassica alba, Cannabis sativa, Curcuma longa, Curcuma aromatica, Eugenia caryophyllata, Evodia officinalis, Paeonia suffruticosa, Rhaphanus sativus, Rheum palmatum, Rhus verniciflua, Trapa bispinosa, Zanthoxylum piperitum ‐ may be potential sources of anti‐oxidants. Eight plants ‐ Citrus aurantium, Cornus officinalis, Gleditsia japonica, Lindera strychnifolia, Phragmites communis, Prunus mume, Schizandra chinensis, Terminalia chebula ‐ may be the potential source of free radical scavengers from natural plant. Nous avons crible l'activite anti‐oxydante de 100 extraits methanoliques aqueux de plantes en utilisant le systeme reactif de Fenton/linoleate, et leur activite de piege a radicaux libres en utilisant le systeme generateur de radicaux libres au 1,1‐diphenyl‐2‐picryl‐hydrazyle. Les resultats suggerent que 14 plantes ‐ Alpinia officinarum, Areca catechu, Brassica alba, Cannabis sativa, Curcuma longa, Curcuma aromatica, Eugenia caryophyllata, Evodia officinalis, Paeonia suffruticosa, Rhaphanus sativus, Rheum palmatum, Rhus verniciflua, Trapa bispinosa, Zanthoxylum piperitum ‐ peuvent etre des sources potentielles d'anti‐oxydants. Huit plantes ‐ Citrus aurantium, Cornus officinalis, Gleditsia japonica, Lindera strychnifolia, Phragmites communis, Prunus mume, Schizandra chinensis, Terminalia chebula ‐ peuvent etre la source potentielle de pieges a radicaux libres a partir de plantes naturelles.
