Isolation of secondary metabolite from n-hexane extract of the stem of Tinospora crispa had been done. The extraction was done by maceration. The extract of n-hexane was separated and purified by chromatography column techniques. Antioxidant activity of the isolated compound was conducted by DPPH (1.1-diphenylpycryl hidrazyl) method with concentration variation of 1000, 500, 250, 125, 62.5, 31.…
