Visnagin, which is found in Ammi visnaga, has biological activity as a vasodilator and reduces blood pressure by inhibiting calcium influx into the cell. The present study demonstrates the anti-inflammatory effect of visnagin on lipopolysaccharide (LPS)-stimulated BV-2 microglial cells. When cells
A new, simple and rapid capillary electrophoresis method was developed for the identification and quantitative determination of two medically active constituents-khellin and visnagin-in the extracts of Ammi visnaga fruits. Micellar electrochromatographic separation of khellin and visnagin was
The furanochromone visnagin is one of the main compounds of Ammi visnaga L. (syn. Khella) with potential effects on kidney stone prevention. After determination of the pharmacokinetic properties of visnagin after intravenous bolus administration in rats, the aim of the present study was to evaluate
An improved, simple, selective, and sensitive reversed-phase high-performance liquid chromatographic (HPLC) assay for khellin and visnagin in Ammi visnaga L. fruits was developed by using an internal standardized technique. The HPLC column was a reversed-phase microBondapack C18 column, the mobile
The content of the furanochromones khellin and visnagin, in the organs of Ammi visnaga (L.) Lam. at different developmental stages, has been examined. Determinations have been performed by means of a high performance liquid chromatography (HPLC) technique which allows both the separation and the
Tea bags including fruits of Ammi visnaga L. are used in Egypt as remedy for the treatment of kidney stones. Our study focuses on developing simple and rapid method utilising HPLC for quantitative estimation of khellol glucoside (KG), khellin (KH) and visnagin (VS) simultaneously. Their
During an examination of Ammi visnaga Lam. suspension cultures for the biosynthesis of furanochromones and related medicinal compounds, visnagin was isolated in crystalline form and identified. Thus, certain medicinally important secondary plant metabolites may be produced in appreciable amounts by
Ammi visnaga L. (syn. Khella, Apiaceae) preparations have traditionally been used in the Middle East for the treatment of kidney stone disease. Visnagin, a furanocoumarin derivative, is one of the main compounds of Ammi visnaga with potential effects on kidney stone prevention. To date, no
Visnagin (4-methoxy-7-methyl-5H-furo[3,2-g][1]-benzopyran-5-one), which is an active principle extracted from the fruits of Ammi visnaga, has been used as a treatment for low blood-pressure and blocked blood vessel contraction by inhibition of calcium influx into blood cells. However, the
Visnagin is a furanochromone and one of the main compounds of Ammi visnaga L. that had been used to treat nephrolithiasis in Ancient Egypt. Nowadays, visnagin was widely used to treat angina pectoris, urolithiasis and hypertriglyceridemia. The potential mechanisms of visnagin involved in
Visnagin (4-methoxy-7-methyl-5H-furo [3,2-g][1]-benzopyran-5-one) is an active principle of the fruit of Ammi visnaga, a plant traditionally used in cardiovascular disorders. We have studied its vasodilator effects in rat vascular smooth muscle. The results demonstrated that visnagin inhibited the
Melanoma is a cancer of melanocyte cells and has the highest global incidence. There is a need to develop new drugs for the treatment of this deadly cancer, which is resistant to currently used treatment modalities. We investigated the anticancer activity of visnagin, a natural furanochromone
Acute pancreatitis (AP) is an exocrine dysfunction of the pancreas where oxidative stress and inflammatory cytokines play a key role in induction and progression of the disease. Studies have demonstrated that antioxidant phytochemicals have been effective in improving pancreatitis condition, but
Plants constitute a source of novel phytotoxic compounds to be explored in searching for effective and environmentally safe herbicides. From a previous screening of plant extracts for their phytotoxicity, a dichloromethane extract of Ammi visnaga (L.) Lam. was selected for further study.
In Egypt, teas prepared from the fruits of Ammi visnaga L. (syn. "Khella") are traditionally used by patients with urolithiasis. The aim of this study was to evaluate whether oral administration of an aqueous extract prepared from the fruits of A. visnaga as well as two major constituents khellin
