Two furanochromones and one furanochromone glycoside were isolated from the fruits of Ammi visnaga (L.) Lam. They were identified as khellin, visnagin, and khellol glycoside by interpretation of spectral analyses. Quantitative determination of furanochromones in A. visnaga (L.) ripe fruits from Hatay region (Turkey) was carried out by ultraviolet spectrophotometry and gas chromatography. In addition, photochemical properties of furanochromones and chemical composition of essential oil were determined.
Ammi visnaga seeds and Artemisia herba-alba shoots were fed to 7-d-old Bovans chicks at 2% and 10% of diet for 9 w. The 10% A visnaga seed was toxic but not lethal to chicks and caused a consistently reduced body weight gain, inefficient feed utilization, enterohepatonephropathy, anemia, and alterations of serum aspartate transaminase and creatine kinase activities and cholesterol, total lipid and uric acid concentrations. The depression in growth and damage to vital organs of chicks fed 10% A herba-alba shoots 2% A visnaga seed, or 2% A herba-alba shoots were less marked.
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 carried out using 10 mmol/l borate, 50 mmol/l sodium dodecylsulfate, 25% (v/v) acetonitrile at pH 9 as running buffer. Ammi visnaga fruits were extracted with methanol and the extracts were directly injected without any purification and pre-separation processes. Coumarin was used as internal standard for quantitation and the limits of detection for khellin and visnagin were 2.36 and 1.97 microg/ml, respectively using UV detection at 245 nm.
