Abstract: The content of dihydromyricetin(DMY)in Ampelopsis grossedentata from different areas was comparatively analyzed,the results showed that the content of DMY was ranked Lijiang city in Yunnan province>Jinxiu Yao Autonomous county of Guangxi Zhuang Autonomous region> Wuping countyin Fujian>Zhangjiajie city in Hunan province>Laifeng county of Enshi Tujia and Miao Autonomous Prefecture from high to low. The content of DMY in Ampelopsis grossedentata from Lijiang city in Yunnan province was significantly highest, and the content of DMY from Laifeng county of Enshi Tujia and Miao Autonomous Prefecture was significantly lowest,there was no significant difference among other areas. On the basis, DMY was extracted from Ampelopsis grossedentata by ultrasonic, microwave, wall breaking methods with ethanol,the results showed that microwave-assisted ethanol extraction could achieve green, energy-saving and high-efficiency extraction state with less amount of ethanol, shorter extraction time and lower solid-liquid ratio.

Key words: Ampelopsis grossedentata, DMY, different origin, extraction
