Six further alkaloids have been isolated from the water-soluble fraction of the ethanolic extract of SCHUMANNIOPHYTON MAGNIFICUM Harms. Two of these are the known compounds trigonelline and rohitukine but the other four compounds are novel. Two of these, named schumagnine and N-methylschumagnine,
The constitutional formulae of two new chromone alkaloids, schumannificine 2 and N-methylschumannificine 3 isolated from the root-bark of SCHUMANNIOPHYTON MAGNIFICUM, H ARMS, have been shown to be linear tetracyclic compounds with ring D being piperidine in nature, on the basis of the chemical
The activity against human immunodeficiency virus (HIV) and herpes simplex virus (HSV), of the non-polar fraction of a methanolic extract of the rootbark of Schumanniophyton magnificum was found to be present in a fraction containing the chromone secondary amine schumannificine 1. Other chromone
