| This paper Semen Hoveniae study in the literature on the basis of its research was the Chemical Constituents, herbal medicine quality standards, extraction and purification of total flavonoids, aimed at improving the quality standards of medicine, to effectively control the quality of ingredients, a better understanding of its main effect of the material foundation for the full development its medicinal resources and provide a theoretical basis.Semen Hoveniae of plants for Hovenia dulcis Thunb with succulent ripe fruit drying the fruit or seeds, first described in《Xin xiu ben cao》by the《People's Republic of China Ministry of Health Drugs standards·Chinese herbal medicines》contains. The collection of 10 different areas of medicine, a TLC; identified impurities in medicine, established by UV-visible and HPLC spectrophotometry Determination of Flavonoids in medicine methods and Determination of Flavonoids in medicine content to enhance Semen Hoveniae of medicine and the quality control.Semen Hoveniae from five isolated flavones components, and its corresponding structural analysis or confirmed, can be used as medicine and the indicators of quality control components.Semen Hoveniae of total flavonoids in the extraction and purification process were studied and inspected a different ethanol concentration, solvent volume times, and the extraction time from the total number of flavonoids extract yield and purity of the impact of the establishment of a four orthogonal factors and three levels of tests, and ultimately establish the best extraction process. And using macroporous resin to the total flavonoid extracts were purified with a selection of different types of resin, inspected the resin static and dynamic adsorption properties, and the kind of concentration and flow rate, concentration and solvent elution volume, and other related factors were optimized, and established the best purification process.
