Triterpenes and antitubercular activity of Byrsonima crassa
(Sociedade Brasileira de Química, 2008-01-01)
We evaluated the potential antitubercular activity of triterpenes obtained from leaves and bark of Byrsonima crassa. From chloroform extracts of the leaves, by bioassay-guided fractionation, we obtained mixtures of known ...

Identification of triterpenes and sterols from pterogyne nitens (fabaceae-caesalpinioideae) using high-resolution gas chromatography
(Soc Chilena Quimica, 2009-09-01)
As part of our ongoing bioprospecting studies on secondary metabolites in plants of Cerrado and Atlantic Rain Forest of São Paulo State (Brazil), we describe the identification of triterpenes and sterols present in the ...
Triterpene benzoates from the bark of Picramnia teapensis (Simaroubaceae)
(Soc Brasileira Quimica, 2001-05-01)
Two new benzoic acid esters of triterpene alcohols [lup-20 (29)-en-28-oic acid 3 alpha, 7 beta -dibenzoate and 3 alpha -hydroxy-lup-20(29)-en-28-ic acid 7 beta -benzoate] were isolated from the stem bark of Picramnia ...
