Identification of antioxidant compound from Asparagus racemosus

Phytother Res. 2004 Sep;18(9):771-3. doi: 10.1002/ptr.1526.


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, 1H NMR, 13C NMR, and 2D NMR). Racemofuran revealed antioxidant property against DPPH with IC50 value of 130 microM.
