천연산물로부터 항산화물질의 탐색

30 kinds of natural products were considered for developing natural antioxidants by improved D.O. analyzing method including simple calculation of Area Under Curve. Several natural products such as Cimicifuge Rhizoma, Epimedii Herba, Atractylodis Rhizoma Alba, Acori Graminei Rhizoma, Mori Cortex Radicis, Aurantii Nobilis Pericarpium were bore nearly same antioxidant effects compared to synthetic powerful antioxidant BHT and also expressed powerful antioxidant effect than ${\beta}-carotene$ such as Eucommiae Cortex, Cinnamomi Cortex, Angelicae Gigantis Radix, Lycii Furctus, Acanthopanacis Cortex, Sophorae Radix, Paeoniae Radix, Geranii Herba. Another method of DPPH was performed for searching natural antioxidant from natural product. Sophorae Radix, Puerariae Radix, Aurantii Nobilis Pericarpium, Atractylodis Rhizoma Alba, Acori Graminei Rhizoma, Corni Fructus, Angelicae Gigantis Radix, Paeoniae Radix were carried higher antioxidant capacity than ${\beta}-carotene$ by DPPH method.
