  author={Xu Hui-qin and He Li-wei and DU Ying-yue and S. Zhang},
The orthogonal test method was used to investigate the effects of solvent volume fraction, extraction time and solvent on the extraction process. The results showed that the best extraction process of the total lignans in Radix Isatidis is 70% ethanol, the extraction time is 2 h, and the amount of solvent is 8 times. The inhibitory effect of the total lignans of Radix Isatidis on RSV was determined by MTT method and cytopathic effect (CPE) method. The total lignans of Radix Isatidis… Expand
