摘要：

To optimize ultrasound-assisted extraction technology of tannin from the succulent stem of Cynomorium songaricum. The content of tannin in C. songaricum samples of different source was comparatively studied. Extraction rate of tannin as indexes, extraction process was optimized by single factor experiment and L9(34) orthogonal experiment. The best extraction technology for ultrasonic extraction were 75% as the extraction solvent ethanol concentration, 600 w as the ultrasonic power, 1:65 as the solid-liquid ratio, 105min as the extraction time and extraction 2 times. According to the results of content determination, C. songaricum samples from Guazhou has the highest tannin content than samples from Xinjiang and Inner Mongolia and in the samples of Guazhou which were harvested in April and May has more content than three-nine C. songaricum (harvested in the third nine-day period after the winter solstice). This study could provide scientific basis for rational development and quality control of C. songaricum. © Maxwell Scientific Organization, 2015.
