RESUMEN
The hydroethanolic extract of the flowering tops of Anthocephalus cadamba (Roxb.) Miq., Rubiaceae, a Bangladeshi medicinal plant, was studied for its potential hypoglycemic effect and antioxidant property in alloxan-induced diabetic rats. The extract induced significant reduction in serum glucose, and transaminases, e.g. aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatases (ALP), activities. Significant changes in the thiobarbituric acid reactive substances (TBARS), peroxidase and catalase levels during the experimental period were also observed. The results established that the hydroethanolic extract of the flowering tops of A. cadamba possesses hypoglycemic property and is able to protect liver and brain from oxidative damages caused by diabetes.
RESUMEN
Trans-isoferulic acid was isolated from the carbon tetrachloride soluble fraction of a methanol extract of the rhizomes of Curcuma longa (Zingiberaceae). The structure of the isolated compound was elucidated by comprehensive analysis of spectroscopic data. This is the first report of its occurrence from this plant.
El ácido trans-isoferulico fue aislado de la fracción soluble en tetracloruro de carbono del extracto metanólico de los rizomas de Curcuma Longa (Zingeraceae). La estructura del compuesto aislado fue elucidada por análisis de los datos espectroscópicos. Este es el primer reporte de su presencia en esta planta.
