    Objectives: This study aimed to investigate value differences among Gastrodiae Rhizoma samples (GM, GC, G1, G2 and G3) in various characteristics as well as to provide basic guideline for various processes such as steaming and drying of Gastrodiae Rhizoma. Methods: Gastrodiae Rhizoma were steamed and dried at different temperature and times. They were divided into samples (GM; cultivated, steamed and dried in Muju, GC; cultivated and dried in China, G1; steamed and dried at 55℃ for 60 hours, G2; steamed and dried at 55℃ for 120 hours, G3; steamed and dried at 70℃ for 120 hours) for experiment. They were extracted using water, freeze dried and powdered to analyze gastrodin content, antioxidant activity and sensory evaluation. Results: Proximate composition and the amount of free sugars of Gastrodiae Rhizoma had a little bit differences. Phenolic and flavonoid content of samples were increased by increasing drying temperature and times. Gastrodin content had different values by drying method and G3 was the highest in comparison with others. Increasing drying times led to a increasing in radical and nitrate scavenging activity in samples. Regarding to sensory evaluation, G3 was selected as the best sample according to its highest hedonic score mean (6.11/7) among all samples for appearance, color, flavor, overall acceptability. Conclusions: The results indicated that G3 sample was effective in views of antioxidant activity, gastrodin content and sensory characteristics. Moreover, Gastrodiae Rhizoma cultivated in Korea were investigated with higher antioxidant activity, gastrodin content and sensory characteristics than those cultivated in China.
