Description

Analysis Note Vitexin is an apigenin flavone glucoside, a chemical coupound found in the passion flower, Vitex agnus-castus (chaste tree or chasteberry), and in the Phyllostachys nigra bamboo leaves. It is also found in the pearl millet (Pennisetum millet). Vitexin is also found in Hawthorn. Improved peak shape for the conjugates was obtained at higher temperatures. The analysis shown here was performed on Ascentis Express RP-Amide. The highest quality LC-MS solvents were used to supply low background interference and low particulate contaminants for robust, trouble-free operation. Cerilliant phytopharma CRMs (PHY82682, PHY89291, PHY89290, PHY89233) provided reliable identification and quantification.
