摘要
采用正交试验以 HPL C测得的灯盏花乙素含量为考察指标 ,对灯盏细辛的提取条件进行优选。结果显示用 15倍于药材重量的 6 0 %乙醇回流提取 2次 ,每次 4 0
The process was optimized on basis of extract yield of scutellarein 7 O glucuronide by content orthogonal design. The best condition is presented as follows: the pulverized Erigeron breviscapus was extracted with 15 fold of its weight of 60% alcohol for two times and 40 min each time.
