Studies On The Preparation Of Effective Constituents In Vaccinium Vitis Idaea L. And The Effectiveness Curing Respiratory Infection Disease

In the experiment, the auther optimized the techniques of the extraction and purification of the effective constituents in Vaccinium vitis idaea L.by using the macropore absorbed resin, the quality and activity of the effective constituents was studied,the optimal technique of extraction was investigated by taking the contents of arbubin and flavonoids as indexs. The techniques of extraction and accumulation of the effective constituents were studied and more than 50% of the effective constituents were determined and the collection rate reached to 10%.The feasibility of the techniques was proved in the large experiments;the quality standard of the effective constituents curing acute and chronic respiratory infection disease was studied and the quality of the effective constituents was controlled by taking the arbubin and flavonoids as indexs,hypericum was determined as the lower limit to control the content of flavonoids and the quality stability of the effective constituents in Vaccinium vitis idaea L.was ensured;the activity of the effective constituents in Vaccinium vitis idaea L.was studied preliminary by taking antibechic,expectorant and the influence to immunity as indexs,the results showed that the remedial effect of the effective constituents in Vaccinium vitis idaea L.exhibited highly antibechic and expectorant actions and also improved the function of immunity.The results of the research contributed to the declaration of taking the effective constituents in Vaccinium vitis idaea L. as material for the Fith New Drug .
