Antileishmanial and immunomodulatory activity of Xylopia discreta.

29 Sep 2009 This study aimed at determining the in vitro antileishmanial activity of the essential oil and eight extracts obtained from Xylopia discreta. J774 and U937 macrophages were exposed to the different substances to establish the median lethal ... Read more...

RP-HPLC analysis of rhinacanthins in Rhinacanthus nasutus: validation and application for the preparation of rhinacanthin high-yielding extract.

30 Aug 2009 A reversed-phase high-performance liquid chromatographic method is described for the simultaneous determination of rhinacanthin-C, rhinacanthin-D, and rhinacanthin-N in Rhinacanthus nasutus leaves. The method involved the use of a TSK-gel ODS-80Ts ... Read more...

Novel pepper extract for enhanced P-glycoprotein inhibition.

30 Aug 2009 OBJECTIVES: Piperine is one of the most promising bioenhancers to date. Methods used for its extraction suffer from drawbacks such as use of organic solvents, poor extraction efficiency, tedious and expensive methodology. These methods are not ... Read more...
