By antimicrobial and cytotoxic-guided fractionation, a bioactive norquinone-methide triterpene, 15 alpha-hydroxypristimerin, was isolated from a South American medicinal plant, Maytenus scutioides. Its structure was determined on the basis of spectroscopic evidence. Successful chemical transformation of pristimerin to netzahualcoyene indicates that the 15-hydroxy compounds seems to be a possibl...

In these work the in vitro antioxidant activity and the in vivo genotoxicity of M. dasyclada was compared to the reference species M. aquifolium and M. ilicifolia. M. dasyclada showed in vitro antioxidant activity comparable to M. aquifolium but lower than M. ilicifolia, being that a inverse Pearson correlation between DPPH IC50 values and total phenolic content was detected (-0.932). The carbo...
