不同产地野生滇龙胆中主要裂环烯醚萜类成分的含量比较
摘要
目的:采用高效液相色谱法测定不同产地野生滇龙胆中龙胆苦苷、獐牙菜苦苷及獐牙菜苷的含量。方法:岛津Shim-pack VP-ODS柱(4.6 mm×150 mm
Objective:To develop an HPLC method for determining the content of gentiopicroside
swertiamarin and sweroside in wild Gentiana rigescens.Method: Column was Shim-pack VP-ODS(4.6 mm×150 mm
5 μm).The mobile phase consisted of CH3OH and water(30∶70).Flow rate was 1.0 mL·min-1 at 25 ℃.Detecting wavelength of gentiopicroside was at 270 nm while swertiamarin and sweroside were detected at 245 nm.Result: The linear rang of calibration curve was 0.4-2 g·L-1 with the relation coefficient of 0.999 7
0.999 6 and 0.998 7 respectively.The average recovery of three active constituents was 100.04%(RSD 1.49%)
98.48%(RSD 1.67%)and 98.46%(RSD 1.15%).Conclusion: The method is accurate and can supply basis for the exploitation and utilization of Gentiana rigescens resources.
