High performance liquid chromatography analysis of the furanochromones khellin and visnagin in various organs of Ammi visnaga (L.) Lam. at different developmental stages.
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 quantitative determination of these chromones. Unripe fruits are the richest in both chromones, but the collection of ripe dry fruits--as it occurs in Egyptian folk-medicine--seems more reasonable because they might not undergo degradation processes during desiccation and storage.
