Preliminary phytochemical and preclinical toxicity studies of Grewia serrulata DC

Preliminary phytochemical evaluation shows the presence of various bioactive constituents. Acute toxicity study reveals that LD50 of AEGS and EEGS is greater than 2000 mg/kg body weight (b wt) in fasted female rats and can be classified under category 5. The 28-day repeated oral toxicity study justified that the No Observed Adverse Effect Level (NOAEL) of G. serrulata DC (GS) is greater than 800 mg/kg b wt/day P.O in rats. There were no delayed effects in GS satellite group. In conclusion GS was found to be non-toxic in tested doses and experimental conditions.
