Maytenus scutioides

Maytenus scutioides (Lourteig and O Donnell) is a subtropical shrub that is distributed in the Chaco (North of Argentina and South of Paraguay and Bolivia). The aerial part of this plant has been used as cardiotonic and the roots as abortive by the inhabitants of these regions. Recently, in their research for new bioactive compounds, Gonzalez et al [252] investigated the root bark of M. scutioides for cytostatic and antibiotic constituents. Thus, by bioactivity-directed fractionation, scutione (191), a new... [Pg.713]

From two Maytenus species collected in Paraguay, two new pristimerin-related compounds were isolated, 15-a-hydroxypristimerin (57), from M. scutioides [72], and 15-a-hydroxy-21-keto-pristimerin (58) from M. catingarum [73], the last one isolated in our laboratory. The structure of compound (57) was elucidated by spectroscopic means, including MS, h and 13C - NMR, and H - 13C heteronuclear... [Pg.665]
