Abstract

Discovery of novel natural herbicides has become crucial to overcome increasing weed resistance and environmental issues. In this article, we describe the finding that a methanol extract of dry long pepper (Piper longum L.) fruits is phytotoxic to lettuce (Lactuca sativa L.) seedlings. The bioassay-guided fractionation and purification of the crude extract led to isolation of sarmentine (1), a known compound, as the active principle. Phytotoxicity of 1 ...
