Résumé
The leaves of Ziziphus mauritiana Lam have been an integral part of the traditional system of medicine for the treatment of inflammation, wounds, fever, asthma and liver disorders. The leaves are utilised as an edible vegetable in rural parts of India and Indonesia. Despite its pharmacological significance, Ziziphus mauritiana Lam lacks scientific evidence on its mutagenic and genotoxic potential. The aim of the present work is to identify bioactive compounds present in the methanol extract of Ziziphus mauritiana Lam leaves (MEZ) using HPLC-ESI-QqQ and to evaluate its mutagenic and genotoxic potential. The phytochemical standardization of the MEZ was done using HPLC-ESI-QqQ. The mutagenic and genotoxic potential of MEZ was tested using bacterial reverse mutation (Ames test), chromosomal aberration, and micronucleus tests. The Ames test was performed in Salmonella typhimurium strains TA98, TA100, TA102, TA1535 and TA1537, and the genotoxic potential was tested in in-vitro using chromosome aberration assay with Chinese hamster ovary (CHO) cells and in-vivo micronucleus test using mouse bone marrow cells. Fifteen phytochemical compounds were identified in HPLC-ESI- QqQ. It was observed from the Ames test that MEZ did not induce gene mutations in the S. typhimurium in the presence or absence of S9 activation. Similarly, no significant increase in the number of structural aberrations was observed in CHO cells with or without S9 activation. The oral administration of MEZ at a dose of up to 2000 mg/kg caused no significant increase in the number of micronucleated polychromatic erythrocytes or in the mean ratio of polychromatic to total erythrocytes. The findings of the present study confirm that MEZ is not-mutagenic and non-genotoxic in the presence or absence of the exogenous metabolizing system.
