| 摘要: |
| 研究了以杜仲鲜叶为原材料加工杜仲原汁的前处理方法，并通过对杜仲叶水提液的口感评价及有效成分含量的测定，筛选出一种较好的杜仲鲜叶发酵方法。结果表明，杜仲鲜叶在沸水上蒸3 min后，装塑料袋，再在真空40 ℃条件下进行发酵处理，利用该法获取的杜仲叶水提液中黄酮、桃叶珊瑚甙、绿原酸的含量分别为5.697，5.602，4.656 g/L，有效成分保存较多且口感较佳。 |

| Study on the fermentation methods for Eucommia ulmoides leaves |
|
|
| Abstract: |
| The optimum preconditioning methods of the natural juice by fresh Euccommia ulmoides leaves were studied.A optimum fermentation of fresh leaves was chosen by tasting the extraction juice and determining the contents of the metabolites in it.The results were as followings:after stemming 3 min,the leaves were put into plastic bags,then fermented in vacuum (-0.06 MPa) at 40 ℃,the contents of the metabolites in the extraction juice are:flavonoids 5.697 g/L,aucubin 5.602 g/L,chlorogenic acid 4.656 g/L.By using this method,the taste of the juice is the best and more metabolites were preserved. |
