Abstract

Extracts from Schizozygia coffaeoides showed antimicrobial activity against Fungal and Bacterial species. Alkaloids isolated using bioassay-guided fractionation were isoschizogaline, schizogynine, and a new indoline alkaloid, 7,8-dehydro-19beta-hydroxyschizozygine, shown to be the most active Antifungal compound. The structure of isoschizagaline, the only active Antibacterial, is revised on the basis of NMR analysis.
