dc.description.abstractA new iridoid named as 1-keto isodehydroiridodiol (1) was isolated from the methanolic extract of the aerial parts of Actinidia polygama Miq. along with nine known compounds (2-10). The chemical structure of the isolated compounds was elucidated on the basis of NMR and MS spectroscopic data. All these compounds were evaluated for their free radical scavenging activities through DPPH and ABTS assays. 1-keto isodehydroiridodiol compound was found to be moderate antioxidatnt agent showing IC50values of 89.7 +/- 2.6 and 129.6 +/- 3.2 mu M in DPPH and ABTS assays, respectively. While 5,7-dihydroxychromone compound expressed the best antioxidant activity showing an IC50 value of 60.3 +/- 0.5 mu M followed by kaempferol having IC50 of 67.2 +/- 0.9 in DPPH assay.; Se aisló un nuevo iridoide denominado 1-cetoisodehidroiridodiol (1) del extracto metanólico de las partes aéreas de Actinidia polygama Miq. junto con nueve compuestos conocidos (2-10). La estructura química de los compuestos aislados se dilucidó sobre la base de datos espectroscópicos de RMN y MS. Todos estos compuestos se evaluaron para determinar sus actividades de eliminación de radicales libres mediante ensayos DPPHy ABTS. Se encontró que el compuesto de 1-cetoisodehidroiridodiol es un agente antioxidante moderado que muestra valores de CI50 de 89,7 ± 2,6 y 129,6 ± 3,2 μM en los ensayos de DPPH y ABTS, respectivamente. Mientras que el compuesto de 5,7-dihidroxicromona expresó la mejor actividad antioxidante mostrando un valor de IC50 de 60,3 ± 0,5 μM, seguido de kaempferol que tenía IC50 de 67,2 ± 0,9 en el ensayo DPPH.-
