Acute Hypoglycemic and Antidiabetic Effect of Teuhetenone A Isolated from Turnera diffusa

Acute Hypoglycemic and Antidiabetic Effect of Teuhetenone A Isolated from Turnera diffusa.

Diabetes mellitus is a chronic degenerative disease that causes long-term complications and represents a serious public health problem. Turnera diffusa (damiana) is a shrub that grows throughout Mexico and is traditionally used for many illnesses including diabetes. Although a large number of plant metabolites are known, there are no reports indicating which of these are responsible for this ac...

Flavonoids and arbutin from Turnera diffusa.

The infusion of the aerial parts of Turnera diffusa was phytochemically examined. Chromatographic procedures led to the isolation of a new flavone glycoside, five known flavonoids and p-arbutin. Structures were determined by 1D- and 2D NMR experiments, as well as ES-MS and UV spectra.

Effects of Panax ginseng, Turnera diffusa and Heteropterys tomentosa extracts on hippocampal apoptosis of aged rats

OBJECTIVE To verify if the medicinal plants Panax ginseng C.A. Mey, Turnera diffusa Willd. ex Schult., and Heteropterys tomentosa O. Mach., which are amply used by the population as tonics and cognition enhancers, could have a protective effect on cell death by apoptosis, since this could be one of the mechanisms of action of these substances. METHODS Aged male Wistar rats (n = 24) were divid...

Gastroprotective activities of Turnera diffusa Willd. ex Schult. revisited: Role of arbutin.

ETHNOPHARMACOLOGICAL RELEVANCE Turnera diffusa Willd. ex Schult. has been used for the treatment of several human disorders including peptic ulcer. OBJECTIVES OF THE STUDY The current study is an attempt to evaluate the anti-ulcerogenic activities of arbutin, a major constituent of Turnera diffusa on two ulcer models. The possible involvement of lipid peroxidation, nitric oxide, IL-6, IL-10, ...
