Wistar rats were treated with the leaf extract containing a single dose of 2,000 mg / kg, v.o. After 14 days, the animals were anesthetized for blood collection and subsequent analysis of the biochemical parameters; they were then euthanized (sodium pentobarbital-100 mg/kg,...

Phenolic derivatives and antioxidant activity of polar extracts from Bauhinia p...

A tea made with the leaves or stem bark of Bauhinia pulchella Benth (Fabaceae) is used in the treatment of diabetes.

The triterpenoid alpha, beta-amyrin prevents the impaired aortic vascular react...

To characterize the pro tective effects of the triterpenoid mixture alpha, beta-amyrin (AMY, 20 mg/kg, during 15 days) on the reactivity of isolated aorta of high- fat diet (HFD)-induced obese mice. Male Swiss mice were fed with HFD or normal diet (ND) for 15 weeks. Contractions of thoracic aorta in response to KCl or phen- ylephrine (PHE) and relaxation by acetylcholine (ACh) or sodium nitroprusside (SNP) were...
