- Abstract
We studied the phytotoxic allelopathic potential of Celosia argentea var. cristata L. against Lepidium sativum L. and identified the allelochemicals in its methanolic leaf extract using bioassay guided fractionation. The results revealed that cockscomb leaf extract fractions were phytotoxic at very low concentration (≥ 50 ppm). The most bioactive fractions were purified for isolation and identification of allelochemicals. Seven potent phenolic allelochemicals (p-coumaric acid, m-coumaric acid, vanillic acid, 4-hydroxybenzoic acid, mhydroxybenzaldehyde, dihydroxybenzaldehyde and 4-hydroxybenzaldehyde) were identified by LCMS. The results suggested that allelochemicals play critical role in phytotoxic allelopathic effects of Celosia argentea in floriculture, natural and in agroecosystems.
