精品 昆虫源代谢物抗菌活性筛选 THE DIFFERENT EXTRACTION CONDITIONS ON THE COUGH AND ASTHMA MEDICINE IN CHILDREN INFLUENCE OF THE CONTENT OF Ca2+ ABSTRACT This paper through the design of a single fried at different times of gypsum, plaster of different single-solvent volume when fried, fried gypsum used alone in different solvents, and compatibility of prescriptions, medicines and other extraction conditions of different particle size were prepared pediatric cough spiritual preparations, And its Suohan calcium were identified, and then by EDTA complexometric titration Ca2+ content preparation, formulation and process selection Spirit cough in children to determine the optimal extraction process, to ensure that the content of Ca2 +meet quality standards. Preliminary results show that a single fried gypsum, the boiling time was 60min, with 300mL distilled water as solvent, the obtained solution the highest concentration of calcium ions. With plaster and other Liuwei decoction, respectively, when the gypsum and licorice decoction when one of the highest concentration of calcium ions. Finally, the conclusions based on the above and taking into account calcium sulfate does not dissolve in the nature of alcohol, so will cast a single fry, fry the remaining ingredients together, gypsum boiled liquid without alcohol precipitation, and the remaining ingredients by alcohol precipitation, then the system of pediatric cough and asthma Spirit, and this process as the best process.
