RESUMEN
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.
Neste estudo, os extratos metanólico, clorofórmico e aquoso de Achillea millefolium e Chaerophyllum villosum foram analisados em relação à citotoxicidade, atividade fitotóxica e inseticida. A citotoxicidade foi analisada através do ensaio de letalidade de artémia, indicando que o extrato metanólico bruto de A. millefolium e o extrato clorofórmico de C. villosum revelaram maior mortalidade de artêmias com DL50 de 52,60 µg/ml e 14,81 µg/ml. A fitotoxicidade foi avaliada utilizando o bioensaio de Lemna minor que revelou que o extrato metanólico bruto de A. millefolium e extrato de C. villosum têm inibição máxima de Lemna minor com Fl50 6,60 µg/ml e 0,67 µg/ml. A atividade inseticida mostrou que dentre todos os insetos estudados, o extrato metanólico de A. millefolium e de C. villosum foi altamente tóxico para Sphenoptera dadkhanicom DL50 = 4,17 µg/ml e 0,34 µg/ml . Por outro lado, diferentes extratos, como A. millefolium e C. villosum apresentaram boa atividade citotóxica, fitotóxica e inseticida de forma dose-dependente.
