To establish an HPLC method for determination of tanshinone IIA in Salvia miltiorrhiza Bunge extract, and observe the protective effect of Salvia miltiorrhiza extract on myocardial ischemia-reperfusion injury in rats. Column used is a Diamonsil C18, mobile phase is methanol-water (75:25), and detection wavelength is 270 nm. Ischemia-reperfusion injury model is replicated, and the size of myocar...

A new megastigmane glycoside, called pipeloside A, and a new aromadendrane type sesquiterpenoid, pipelol A, were isolated from the MeOH extract of the aerial part of Piper elongatum VAHL. along with a known megastigmane glycoside, byzantionoside B. The structures of these compounds were elucidated on the basis of spectroscopic data and chemical evidence.

Nitric oxide (NO) is a key mediator that plays an important role in pathogenesis of various chronic diseases like Alzheimer’s disease and Parkinson’s disease. Additionally, there is a great attitude for finding natural compounds, which could control and inhibit NO production in pathological conditions. Therefore, we were encouraged to investigate the effects of some Lamiaceae species on NO prod...

Do extrato butanólico das flores de Ononis vaginalis Vahl. Symb. foram isolados dois novos glicosídeos norfenilpropanóides: 1 β-D-glicopiranosil-2-(4’hidroxifenil) (E)-eteno (trans-vaginosídeo) e 1 β-D-glicopiranosil-2-(4’hidroxifenil) (Z)-eteno (cis-vaginosídeo), e a flavanona C-glicosilada (+) 6-C-β-D-glicopiranosil (2S) naringenina (hemifolina). As estruturas destes compostos foram determina...

Salvia divinorum is a new recreational drug where few studies have been conducted on its prevalence and predictors of use. Using a sample of undergraduate students, this study investigated these issues. While a small number reported experimenting with salvia, logistic regression models showed that demographics, marijuana use, and self-control are statistically significant predictors. The effect...

Natural products from plants have been used since ancestral times to treat a wide variety of diseases worldwide. Plants of the genus Salvia (Sage) have been reported to be used for the prevention and treatment of various diseases and ailments. In particular, some Salvia species have been used in traditional medicine to treat diseases caused by protozoan parasites of the genera Trypanosoma, Leis...
