摘要
目的测定土党参中党参炔苷的含量,为土党参的质量控制及引种栽培等提供科学依据。方法采用高效液相色谱法分析,依利特-ODS2(250mm×4.6mm,5μm),以乙腈-水(20:80)为流动相,检测波长为270am。结果测定了贵州11个不同产地的土党参中党参炔苷的含量,其范围为0.686~4.035mg·g^-1。结论该方法快速简便,重复性好,可用于土党参的质量评价。
Objective To determine lobetyolin in Radix Campanumoeae . Methods Hypersil ODS 2(250 mm×4.6 mm,5 μm) was used with acetonitrile - water (20: 80) as the mobile phase and DAD detection was at 270 nm. Results Radix Campanumoeae from 11 habitats in Guizhou were analyzed. The content of lobetyolin ranged from 0.686 - 4. 035 mg ·g^- 1. Conclusion The method is simple, quick and reproducible. It can be used to control the quality of Radix Campanumoeae.
