Method: RP- HPLC, linear gradient elution, LC/MS, etc. were used to determine the fingerprint and identify the main pea ks in the HPLC fingerprint.
方法：利用RPHPLC ，采用线性梯度洗脱等进行指纹图谱的测定，并应用LC/MS技术指认指纹图谱中的主要色谱峰。
Dual linear gradient elution can be performed with two specially made glass container and a high pressure constant flow pump.
用两个特制的玻璃容器及一台平流泵即可实现二元线性梯度洗提。
