Abstract
To compare three traditional extraction methods (extraction with cold water, ultrasonic extraction and circumfluence extraction with hot water) of gastrodin and gastrodigenin, the best one is circumfluence extraction with hot water. And the optimum extraction process was carried out through orthogonal experiment. The best extraction temperature was 60°C, and extracted 3 times by 70% alcohol. The time for each extraction was 1 hour, and the quantity of alcohol used 10 times more than the quantity of sample. The contents of samples in different harvest festivals (from August to January) were determined. The best time is in September.
