| Abstract: | OBJECTIVE To select the optimal extraction procedure for shikimic acid from the Pine needle of Pinus yunnanensis Franch.METHODS Taking shikimic acid content as the index,L9(34)orhogonal design method was used for optimization and HPLC for determination.The influential factors such as concentration and volume of ethanol,time of extraction and frequency of extraction.RESULTS The toptimum extraction process was as follows,12 times of 80%alcohol,refluxing and extracting for 2 times,each time for 1.5 h.CONCLUSION This optimized process is simple,stable and efficient. |
