Five new 1,3-diarylpropan-1-ols, combretol A-E (1- 5), together with one known coumarin (6) and ten known triterpenes (7-16), were isolated from Combretum yunnanense. Their structures were determined by spectroscopic investigation, including ¹H and ¹³C NMR, NOESY, HSQC, HMBC, and HRESIMS analyses. This is the first report on the occurrence of 1,3-diarylpropan-1-ols and coumarin in the Combretum...

A new species of Combretum, C. pendulum, is described and illustrated. Taxonomic notes on typifications for apetalum winitii, synonymisations alatum quadratum are presented. key to Thai Combretum also provided.

Pesticides poses great threat to the environmental sustainability by affecting its microbial flora and fauna. Fungi are well known for the secretion of extracellular hydrolases for the degradation of these hazardous chemicals from its ambient environment. Hydrolase secreting soil fungi Penicillium aculeatum ITCC 7980.10 was selected for the study of its monocrotophos degrading efficiency under ...

BACKGROUND Candida albicans is one of the organisms living on the human body symbiotically, but, in hosts with low immunity it becomes one of the most pathogenic fungal organisms. Combretum zeyheri has been reported to have antifungal, antibacterial and antioxidant activities. Medicinal plants are believed to be non-toxic by the general public. Toxicity studies, however, have indicated that the...

Wound healing is a fundamental response to tissue injury and several natural products have been shown to accelerate the healing process. The present study was undertaken to determine the safety and efficacy of the topical treatment of acetone leaf extracts of Combretum imberbe, Combretum nelsonii,Combretum albopuntactum and Terminalia sericea based on their in vitro antimicrobial activity. Four...

Combretum imberbe is used widely in Africa inter alia for treating bacterial infections. In addition to four known triterpenoids, 1alpha,3beta-dihydroxy-12-oleanen-29-oic (1), 1-hydroxy-12-olean-30-oic acid (2), 3,30-dihydroxyl-12-oleanen-22-one (3), and 1,3,24-trihydroxyl-12-olean-29-oic acid (4), a new pentacyclic triterpenoid (1alpha,23-dihydroxy-12-oleanen-29-oic acid-3beta-O-2,4-di-acetyl-...
