摘要

Phytochemical studies of Aframomum meleguata and Monodora myristria seed and leaf extracts revealed the presence of bioactive compounds comprising alkaloids (0.29-5.64 percent), flavonoids (0.12-8.29 percent), saponins (0.02-1.24 percent), tannins (0.03-0.39 percent), and phenols (0.02-0.39 percent). The growth of Sclerotium rolfsii, which causes basal stem rot in cowpea {Vigna unguiculata) and other crops such as tomatoes and tobacco, was inhibited in vitro by the extracts of both plants. The extracts from A. meleguata seed, M. myristica and A. meleguata leaves and M. myristica seed showed 86.65, 53.19, 43.47 and 39.31 percent inhibition, respectively. Analysis of chemical composition through infrared spectroscopy showed that the most active phytoconstituents are aldehydes, ketones, amines and phenolic compounds contained in A. meleguata seeds. The fungitoxicity of the extracts from A. meleguata seed was higher (86.65 percent) than that of benomyl (86.20 percent), a synthetic fungicide.
