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
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
OBJECTIVE
The present study was used to design simple, accurate and sensitive reversed phase-high-performance liquid chromatography RP-HPLC and high-performance thin-layer chromatography (HPTLC) methods for the development of quantification of khellin present in the seeds of Ammi
An evaluation has been made of the action of khellin, a furochromone derivative from Ammi visnaga, at the dose of 50 mg q.i.d. during four weeks, on the plasma lipids of 20 non-obese normolipaemic male subjects after a placebo period of two weeks. The plasma lipids were measured each week and one
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
Cytochrome P450 family 1 (CYP1) enzymes catalyze the metabolic activation of environmental procarcinogens such as benzo[a]pyrene, B[a]P, into carcinogens, which initiates the process of carcinogenesis. Thus, stopping the metabolic activation of procarcinogens can possibly prevent the
Teas prepared from the fruits of Ammi visnaga L. (syn. "Khella") have been traditionally used in Egypt as a remedy to treat kidney stones. It was the aim of our study to evaluate the effect of a Khella extract (KE) as well as the two major constituents khellin and visnagin on renal epithelial injury
