摘要
目的:研究射干药材经枯草芽孢杆菌和黑曲霉发酵后其中6种异黄酮成分含量的变化。方法:利用HPLC检测经黑曲霉和枯草芽孢杆菌发酵20 d时射干药材中6种异黄酮成分的含量,并与发酵前比较,计算各成分的含量变化。结果:经枯草芽孢杆菌发酵能增加鸢尾黄素和次野鸢尾黄素的含量,经黑曲霉发酵能增加次野鸢尾黄素的含量。结论:利用枯草芽孢杆菌和黑曲霉发酵后,可使射干药材中苷元成分增加。
Objective： To investigate six kinds of isoflavone constituent of Belamcandae Rhizoma after fermentation by Bacillus subtilis and Aspergillus niger. Methods： To compare with the content of six kinds of isoflavone before and after （20 days ）fermented by B. subtilis and A. niger. The contents were determined by HPLC method. Results： The contents of tectorigenin and irisflorentin can be raised after ferment by B. subtilis, and irisflorentin can be raised after ferment by A. niger. Conclusion： The content of aglycone can be raised, after Belamcandae Rhizoma was fermented by B. subtilis and A. niger.
