Crataegus (hawthorn) has long been used as a folk medicine all around the world. Most of the studies with Crataegus species focus on effects on heart failure and cardiovascular disease. The pharmacological effects of Crataegus have been attributed mainly to the content of flavonoids, procyanidin, aromatic acid and cardiotonic amines. The present study(More)
From the roots of Salvia syriaca L., in addition to known terpenoids, a new rearranged diterpene, named salvisyrianone, was isolated. The structure of the new compound was assigned from spectral data. The crude extract and the single compounds were tested for cardiovascular parameters using Wistar Albino rats. Antihypertensive activity was established in(More)
Five diterpenoids, three steroids, four triterpenoids and one flavonoid were isolated from the roots of Salvia amplexicaulis Lam. (Lamiaceae). Structures of these compounds were elucidated by spectroscopic analysis. The crude extract and the pure compounds were tested for cardiovascular parameters using Wistar Albino rats. The crude extract, and(More)
OBJECTIVE Flavonoids are an important group of recognized antioxidants in plants. Luteolin (LUT) is a natural flavonoid in the plant kingdom. This study was aimed to investigate the effects of the LUT in the liver, kidney and brain of pentylentetrazol (PTZ)-induced seizure and the relationship between nitric oxide synthases (iNOS, eNOS) and matrix(More)
A balloon-tipped catheter has recently become available which, when placed in the pulmonary artery, in addition to enabling the usual measurements of pulmonary arterial pressure, pulmonary capillary wedge pressure, and cardiac output by thermodilution, measures mixed venous oxygen saturation (SvO2) by spectrophotometry. Unlike the measurement of cardiac(More)
From the roots of Salvia eriophora (Lamiaceae), a new compound, 4,14-dihydroxysaprorthoquinone, was isolated in addition to ten known diterpenoids. The structure of the new compound was established by spectroscopic analysis. The crude extract of the plant and the isolated diterpenoids were tested for their cardiovascular activities using Wistar Albino rats.(More)
