Biological assays including; phytotoxicity, brine shrimp lethality, antileishmanial and insecticidal activities were carried out on crude methanolic extracts of stems and leaves of R. nervosus and their fraction namely; n-Hexane, CHCl3, EtOAc, and MeOH fractions. The highest significant phytotoxicty activity showed by chloroform, n-hexane fractions and crude extract of leaves, the growth regulation were (95%, 90% and 90%) respectively against Lemna minor, while ethyl acetate fraction and n-hexane fractions of stems displayed significant phytotoxicty (100% and 90%) respectively against Lemna minor at high dose (1000μg/ml). The results obtained from cytotoxicity assays revealed that none of the fractions are cytotoxic. The chloroform fraction of stems was showed good antileishmanial activity against L. major with LC |
