A Search For Agrochemicals From Peruvian Plants
The objective of this study was the isolation and identification of the antifeedant, antifungal, and antibacterial active constituents from Peruvian plants. 5,7-Dihydroxy-6,8-dimethyl-4'-methoxyflavanone (matteucinol) was isolated from the root of Miconia cannabina. This is first report of the spectral data of matteucinol. Matteucinol showed significant antifungal activity (Pythium ultimum 135%). Also reported is the isolation of sitosterol and medicarpin from the toluene extract of the wood of Dalbergia monetaria. Medicarpin possessed high antifungal (Rhizoctonia solani, 145% and Helminthosporium teres, 100%) and antibacterial activity (Xanthomonas campestris, 100%) along with high antifeedant activity against the cotton boll weevil (Anthonomus grandis, 98%).
