ANTIFUNGAL CONSTITUENTS OF CHENOPODIUM-PROCERUM

Four compounds were isolated from a dichloromethane extract of the aerial parts of Chenopodium procerum by different chromatographic techniques: the isoflavones irilin A and irilin B, the flavanone dihydrowogonin, and the sesquiterpene pygmol. The latter three inhibited the growth of the plant pathogenic fungus Cladosporium cucumerinum. Four flavonol glycosides were obtained from the non-fungicidal methanol extract by Sephadex LH-20 gel filtration and centifugal partition chromatography. The structures of the compounds were eluacidated by spectroscopic methods (UV, H-1-NMR, C-13-NMR, MS).
