Semen Extraction Process And Ingredients

Wild jujube seed is sour to the taste, neutral in nature and distributed to the heart liver and hall bladder channels . It has the effects of nourishing the heart and liver calming the mind and arresting sweating. The research of the pharmacodynamics shows that Mild jujube seed has the function of restraining nerve centre. It is low toxic safe-using and has very distinctly officinal value.This thesis includes two parts:The first part introduces the herbal medicine origin, chemical components, pharmacological effects and clinical applications.The second part can be divided into four aspects:1. Researching the chemical components of Wild jujube seed. Extracting and separating some compounds, confirming the structures through the method of UV IR MS ~13CNMR.2. Confirming the best extractive technics of total saponine .through the four factors(concentration of ethanol time of extraction dosage of extractive solvent and times of extraction)three levels orthogonal test, according to the charactors of the main saponine of Wild jujube seed. The best extractive technics is that adding 8 times 80% ethanol to the medicinal materials, refluxing 2 times, 3 hours per time. And researching the best method of using Macroporous resin to separate saponine.3. Determining jujubosides A and spinosin through UV spectrophotometry and HPLC chromatogram. Establishing the quality standard of total flavone extracted from Wild jujube seed.
