Chen leaves. The optimum parameters were: extraction time 15 min, irradiation power 300 W, irradiation temperature 34℃, pH 5.2, amount of cellulase 3.5 mg·g-1. Under the optimal conditions, the average extraction yield of biochanin A was 1.579 mg·g-1. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2011.03.021
