DETERMINATION OF NON-TOXIC DOSE OF DIFFERENT FRACTIONS OF LAWSONIA INERMIS LEAVES IN ALBINO WISTAR RATS ON THE BASIS OF HAEMATOLOGICAL AND BIOCHEMICAL PARAMETERS

Medicinal properties in Lawsonia inermis are due to the presence of bioactive compounds and can also show adverse effects at high concentrations. In the present study we have determined the nontoxic concentration of hexane, ethyl acetate and methanol fractions of plant leaves. 50 wistar albino rats of both sexes were used as experimental animal and were randomly divided into 4 groups viz. Group 1 (control), Group 2 (Hexane fraction), Group 3 (Ethyl acetate Fraction) and Group 4 (Methanol Fraction). Groups 2, 3 and 4 were further divided into following sub groups, Group 2A (H) (100mg/kg), Group 2B (H) (250mg/kg), Group 2C (H) (500mg/kg), Group 3A (H) (100mg/kg), Group 3B (H) (250mg/kg), Group 3C (H) (500mg/kg), Group 4A (H) (100mg/kg), Group 4B (H) (250mg/kg) and Group 4C (H) (500mg/kg). Rats in Group 1 (control) received 3% DMSO as solvent for dissolving fractions. All the doses were administered orally with the help of polythene cannula and were given once in a day, followed up to 21 days. After 21 days, blood was collected from orbital sinus of each rat and was utilized for Biochemical and Haematological tests. Data illustrates that body weight increased in dose dependent manner and also no death or toxic signs were observed in Hexane, ethyl acetate and methanol fractions at 100mg/kg, 250mg/kg and 500mg/kg concentration indicating no adverse effect of L. inermis leaves extract on wistar abino rats at these doses. Thus, this plant is safe and can be used as medicinal plant.
