Identification of antioxidant compound from Asparagus racemosus

Roots of Asparagus racemosus were found to possess antioxidant property. DPPH autography-directed separation resulted in the identification of a new antioxidant compound named racemofuran (3) along with two known compounds asparagamine A (1) and racemosol (2). The structure of 3 was fully characterized by spectroscopic data (UV, MS, H-1 NMR, C-13 NMR, and 2D NMR). Racemofuran revealed antioxidant property against DPPH with IC50 value of 130 muM.
