Abstract:
Objective: The optimum extraction process parameters of Cistanche deserticola were selected to study the effects of different drying methods on five phenylethanoid glycosides. Methods: Single factor screening combined with Box-Behnken response surface method was used to optimize the extraction process. After optimal conditions were extracted, HPLC method was used to detect the content of echinacoside, cistanche A, verbascoside, isoacteoside, and 2’-acetylacteoside in different drying methods, and one-way ANOVA, cluster analysis, principal component analysis and close value analysis were used to analyze the content of five phenylethanoid glycosides to choose the best drying method. Results: Optimal extraction process was as following: methanol volume fraction was 55.14%, liquid to material ratio was 46.39, extraction time was 38.50 min. Cluster analysis, principal component analysis, and close value analysis showed that the quality of C. deserticola obtained by freeze-drying method was the best, followed by drying at 80 ℃ and the lowest at 40 ℃. Conclusion: Using this process to extract C. deserticola, the five phenylethanoid glycosides are completely and fully extracted. Although the freeze-drying method of C. deserticola has the highest active ingredient retention, from the production point of view, the 80 ℃ drying method can achieve a balance of cost and efficiency.
