Shade dried and coarsely powdered root was extracted with methanol and the methanolic extract was subjected to the column chromatography over silica gel (100-200 mesh) packed in Hexane: Ethyl acetate (2:8). The elution of the column was done based on the polarity of the solvent. The fraction was distilled in a rotary evaporator and the remnant was purified by using preparative HPLC and it was confirmed by spectroscopic analysis using 1 H NMR. Further, 1 H NMR (400 MHz) was recorded with Bruker 400 MHz spectrometer in CDCl3 with tetramethylsilane (TMS) as the internal standard. Multiplicities are reported by using the following abbreviations: s = singlet, d = doublet, t = triplet, q = quartet, m = multiplet, sep = septet, br = broad resonance. All the NMR spectra were obtained at ambient temperature.
