ABSTRACT
This study was aimed to establish an HPLC method for simultaneous content determination of valtrate, acevaltrate, and their degradation products, which were baldrinal and 11-ethoxyviburtinal, in Valeriana jatamansi Jones. The separation and quantification of 4 constituents mentioned above were performed on an Agilent ZORBAX SB-C18 (4.6 mm×250 mm, 5 μm). The mobile phase consisted of water (A) - acetonitrile (B) with an optimized gradient program. The flow rate was 1 mL·min-1. The column temperature was set at 25℃. The wavelength was set at 241 nm. And the injection volume was 10μL. The results showed that among 14 different places of V. jatamansi, the 4 contents determined were different. The contents of valtrate, acevaltrate, and baldrinal in the Yunnan Baoshan Mount were the highest. And the content of 11-ethoxyviburtinal was the highest in Yunnan Dali. It was concluded that the method was with good precision, reproducibility and stability. And it was suitable for the determination of 4 valepotriates ingredients in V. jatamansi. It also provided references for the quality control and exploitation of V. jatamansi.
