摘　　要：采用超微粉碎物理破壁技术对杜仲雄花进行破壁,以杜仲雄花破壁率为指标,研究了粉碎时间、雄花水分含量和投料量对杜仲雄花破壁率的影响,并应用响应面曲线法对超微粉碎破壁杜仲雄花条件进行优化。同时测定破壁前后总黄酮、京尼平苷、桃叶珊瑚苷和绿原酸的浸出率。响应面法优化结果表明,最佳破壁条件为:粉碎时间8 min,投料量为100 g,雄花水分含量为6%,破壁率可达100%,通过对超微粉碎破壁处理前后花粉液显微镜下观察,表明超微粉碎具有很好的破壁效果,能促进总黄酮、绿原酸等内容物的释放,提高得率。The ultra-fine powder physical wall-breaking technology was used to break the wall of Eucommia ulmoides male flowers.Taking the wall-breaking rate of Eucommia ulmoides male flowers as an index,the effects of crushing time,water content of Eucommia ulmoides male flowers and feeding amount on the wall-breaking rate of Eucommia ulmoides male flowers were studied.The response surface curve method was used to optimize the conditions for breaking the wall of Eucommia ulmoides male flowers with ultra-fine powder and determine the leaching rate of flavonoids,aucubin,geniposide and chlorogenic acid before and after wall-breaking.Response surface methodology optimization results showed that the optimal wall-breaking conditions were as follows:Crushing time 8 min,feeding amount 100 g,water content of male flower 6%,wall-breaking rate up to 100%.Through microscopic observation of pollen liquid before and after ultra-fine powder wall-breaking treatment,it was shown that ultrafine powder had good wall-breaking effect,could promote the release of total flavonoids,chlorogenic acid and other contents,and improve the yield.
