Cytotoxic, Phytotoxic and Insecticidal Potential of Achillea millefolium L. and Chaerophyllum villosum wall. ex dc.

Abstract

The methanolic, chloroformic and aqueous extract of Achillea millefolium and Chaerophyllum villosum were investigated for cytotoxicity, phytotoxic and insecticidal activities. Cytotoxicity was investigated by brine shrimp lethality assay indicating that the crude methanolic extract of A.millefolium and chloroformic extract of C.villosum revealed highest mortality of brine shrimps with (LD50 of 52.60 µg/ml) and (14.81 µg/ml). Phytotoxicity was evaluated using the Lemna minor bioassay which revealed that the crude methanolic extract of A.millefolium and C.villosum extract has maximum inhibition of Lemna minor with (Fl50 6.60 µg/ml) and (0.67 µg/ml).The insecticidal activity showed that among all the insects studied it was observed that methanolic extract of A. millefoliumand C. villosum was highly toxic to Sphenoptera dadkhani with (LD50 =4.17 µg/ml) and (0.34 µg/ml). From the present study it can be concluded that different extracts from A. millefolium and C. villosum showed good cytotoxic, phytotoxic and insecticidal activity in a dose dependent manner.
