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.
