Anti-stress and anti-oxidant effects of roots of Chlorophytum borivilianum (Santa Pau & Fernandes)

The aqueous extract of C. borivilianum (250 mg/kg for 7 days) significantly reverted the elevated levels of plasma glucose, triglycerides, cholesterol and serum corticosterone and also reduced the ulcer index, adrenal gland weight more as effectively as the standard drug (diazepam) in rats. At 125 mg/kg po, it showed a mild anti-stress activity. Under in vitro 1,1-diphenyl-2-picrylhydrazyl (DPPH*) free radical scavenging assay and lipid peroxidation assay the extract considerably inhibited, in a dose-dependent manner, the levels of DPPH* free radicals and thiobarbituric acid reactive substances, respectively thus showing significant antioxidant property. The results suggested that it could be used for the treatment of oxidative stress-induced disorders.
