摘要: 目的 建立HPLC同时测定钩吻提取物中钩吻素子、钩吻素甲及16-表伏康树卡平碱3种生物碱含量的方法。方法 采用YMC C18(250 mm × 4. 6 mm,5 μm)色谱柱,以乙腈和0.025 mol·L-1磷酸二氢钾(磷酸调pH至3.0)水溶液进行梯度洗脱;检测波长为254 nm,柱温30℃,进样量10 μL,流速1.0 mL·min-1结果 钩吻素子、钩吻素甲和16-表伏康树卡平碱质量浓度分别在32.2~322、34.4~344、6.2~62 μg·mL-1内与峰面积呈良好的线性关系,加样回收率分别为98.6%、101.1%、98.3%,RSD分别为1.7%、1.3%、1.1%。结论 该方法准确、简便、重现性好,可用于钩吻提取物中钩吻素子、钩吻素甲及16-表伏康树卡平碱的含量测定。

Abstract: Objective To develop a method for the determination of three alkaloids in extracts from Gelsemium elegans Benth. by HPLC. Methods YMC C18 (250 mm × 4. 6 mm, 5 μm) column was used with acetonitriles-0.025 mol·L-1 KH2PO4 solution (phosphoric acid was used to adjust pH to 3.0) with gradient elution as the mobile phase and 1.0 mL·min-1 as the flow rate. The detection wavelength was 254 nm. Results The linear ranges of koumine, gelsemine and 16-epivoacarpine were 32.2~322, 34.4~344, 6.2~62 μg·mL-1, respectively. The average recoveries were 98.6%, 101.1%, 98.3% with RSD of 1.7%, 1.3%, 1.1%, respectively. Conclusion This method is accurate, simple and reliable, and can be used for quality control of extracts from Gelsemium elegans Benth.
