Limonoids from the stem bark of Khaya grandifoliola

Phytochemistry, 2008
Three limonoids, deacetylkhayanolide E (1), 6S-hydroxykhayalactone (2), and grandifolide A (3), along with three known ones, were isolated from stem bark of the Nigerian medicinal plant Khaya grandifoliola. Their structures were characterized on the basis of the application of spectroscopic methods.

Khaya grandifoliola C.DC: a potential source of active ingredients against hepatitis C virus in vitro

Archives of Virology, 2016
In this study, we examined the antiviral properties of Khaya grandifoliola C.DC (Meliaceae) on the hepatitis C virus (HCV) life cycle in vitro and identified some of the chemical constituents contained in the fraction with the most antiviral activity. Dried bark powder was extracted by maceration in a methylene chloride/methanol (MCM) system (50:50; v ...

Anti-Anaemic Activity of Spondias mombin and Khaya grandifoliola Aqueous Extracts on Rats

Journal of Pharmacy and Bioresources, 2007
Aqueous extracts of Spondias mombin leaf and Khaya grandifoliola stem bark at various doses were investigated for anti-anaemic activity in an in vivo model using albino rats. Activity was determined by measuring haematological parameters like packed cell volume (PCV), haemoglobin count (Hb) and white blood cell count (WBC).
