Abstract
The current study was designed to explore the phytotoxic potential of extracts/fractions of various parts of Pistacia integerrima and isolated flavonoids (1-3) against Lemna aequinoctialis. The results demonstrated marked phytotoxic activity of extracts/fractions of different parts of the plant when studied at different concentrations (10, 100 and 1000 µg/mL). The overall results showed that roots of the plant were most phytotoxic as compared to other parts while chloroform and ethyl acetate fractions were most phytotoxic fractions. The isolated flavonoids (1-3) strongly supported the phytotoxic activities of extracts in a dose-dependent manner. POM analyzes complemented the use of these compounds as potential safe herbicides in multiple pharmaceutical applications. In short, it is concluded that the different parts of the plant and isolated flavonoids possessed significant phytotoxic activity and thus could be a potentially safe new source as herbicidal.
