本文以水晶刺葡萄叶片和新梢为试验材料,采用超声波辅助提取白藜芦醇,高效液相色谱(HPLC)法检测其含量,并分别对烘干温度、破碎度对其白藜芦醇含量的影响进行研究.结果表明,水晶刺葡萄样品前处理在50~100℃范围内最佳烘干温度为90℃,在30~100目范围内最佳粉碎度为40目,在此处理下,水晶刺葡萄叶片白藜芦醇含量达到6.22±0.34μg/g,水晶刺葡萄新梢白藜芦醇含量达到11.23±0.29μg/g.

　　In this paper, ultrasonic-assisted method were used to extract resveratrol from leaves and yound sprouts of Vitis davidii Foex Shuijing respectively, to determine the resveratrol content by HPLC method The influences of different drying temperature and degree of aperture on the content of resveratrol and the content variation of resveratrol in leaves and young sprouts of Vitis davidii Fo(e)x Shuijing were investigated.The results showed that the optimum drying temperature and degree of fragmentation were 90 ℃ and 40 meshes respectively, in...
