The tumour vasculature is an attractive target for therapy. Combretastatin A-4 (CA-4) and A-1 (CA-1) are tubulin binding agents, structurally related to colchicine, which induce vascular-mediated tumour necrosis in animal models. CA-1 and CA-4 were isolated from the African bush willow, Combretum

Extracts of leaves of different species of the genus Combretum have been used historically to treat a variety of medicinal problems. However, little is known about the active components conferring therapeutic properties to these extracts. In the present studies, we evaluated biochemical properties

Five new triterpene glucosides, quadranosides I-V (1-5), have been isolated from a MeOH extract of the seeds of Combretum quadrangulare, together with 13 known compounds. The structures of compounds 1-5 were elucidated on the basis of spectroscopic analysis. Among the new triterpene glucosides,

The MeOH extract of leaves of Combretum quadrangulare showed significant hepatoprotective effect on D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced experimental liver injury in mice and on D-GalN/tumor necrosis factor-alpha (TNF-alpha)-induced cell death in primary cultured mouse

Hepatoprotective effect of MeOH, MeOH-H2O (1:1) and H2O extracts of Combretum quadrangulare seeds were examined on D-galactosamine (D-GalN)/tumor necrosis factor-alpha(TNF-alpha)-induced cell death in primary cultured mouse hepatocytes. The MeOH extract showed the strongest inhibitory effect on

BACKGROUND The 3β, 6β, 16β-trihydroxylup-20(29)-ene (TTHL) is a pentacyclic triterpene obtained from a medicinal plant named Combretum leprosum. In folk medicine, this plant is used to treat several diseases associated with inflammation and pain. We previously demonstrated that TTHL presents a

The combretastatins are derived from an African medicinal plant Combretum caffrum (Combretaceae). They have previously been shown to be potent inhibitors of microtubule assembly that cause marked haemorrhagic necrosis in murine subcutaneous tumors. Promising clinical trial results with

Herbal plants with antioxidant activities are widely used in Ayurvedic medicine for cardiac and other problems. Arjunolic acid is one such novel phytomedicine with multifunctional therapeutic applications. It is a triterpenoid saponin, isolated earlier from Terminalia arjuna and later from Combretum
