متن کاملBiological Screening of Euphorbia Aellenii
Fractions obtained from partitioning of aerial methanolic extract of Euphorbia Aellenii with chloroform (E2), ethyl acetate (E3), n-butanol (E4) and water (E5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. Sample E2 appeared to have significant phytotoxic activity. In the insecticidal screening study o...
