Abstract

The present study was undertaken for estimation of chemical and phytochemical composition of ashwagandha (Withania somnifera L.) roots of promising genotypes viz. HWS-08-14, HWS-08-18, HWS-1228, HWS-1229 and selection-2B & varieties JA-20 and RVA-100. Chemical parameters viz. crude fibre, minerals (Fe, Cu, Zn, Mn), starch, total sugars, reducing sugars, non-reducing sugars were analyzed in ashwagandha roots. Crude fibre content ranged from 17.4 to 37.3 %, Fe content ranged from 595.83 to 983.33 ppm, Cu content ranged from 8.40 to 13.72 ppm, Zn content ranged from 16.33 to 41.00 ppm and Mn content ranged from 16.80 to 33.46 ppm. Starch, total sugars, reducing sugars and non-reducing sugars contents ranged from 7.61 to 8.22 mg/g, 5.33 to 6.89 mg/g, 0.40 to 0.64 mg/g and 4.87 to 6.33 mg/g, respectively. Phytochemical parameters viz. total alkaloids and tannins were also analyzed. Total alkaloids and tannins content ranged from 0.26 to 0.31 % and 0.66 to 0.84 mg/g, respectively.
