【摘要】 目的:检测不同干燥方法对天麻质量的影响。方法:采用RP-HPLC法测定真空冷冻干燥法和传统的水煮烘干法加工后的天麻中的天麻素的含量,并比较两者的外观特征。结果:采用真空冷冻干燥法加工成的天麻中天麻素的含量明显高于使用传统的水煮烘干法加工成的天麻,外观品质好。结论:真空冷冻干燥法能够较大限度地保证天麻的药用价值和外观品质。更多还原

【Abstract】 AIM: To evaluate the quality of Rhizoma gastrodiea processed by different drying methods. METHODS: Vacuum freeze drying and oven drying were adopted. The content of gastrodin was determined by RP-HPLC. RESULTS: The content of gastrodin of Rhizoma Gastrodiae processed by vacuum freeze drying was significantly higher than that by boil with water and oven drying. CONCLUSION: The method of vacuum freeze (drying) can prevent Rhizoma Gastrodiae from degradation of gastrodin, to keep the appearance, to make Rhizoma Gastrodiae convenient for further processing.更多还原
