摘要:目的 采用反相高效液相色谱法同时测定温阳振衰颗粒中人参皂Rg1、人参皂苷Re、人参皂苷Rb1的含量。方法 采用Agilent TC-C18色谱柱(4.6 mm×250 mm,5 ?m),流动相为乙腈-0.05%磷酸水,梯度洗脱(0~35 min,19%乙腈;35~58 min,19%~29%乙腈;58~70 min,28%乙腈;70~100 min,29%~40%乙腈),流速1.0 mL/min,检测波长203 nm,柱温35 ℃。结果 人参皂苷Rg1、人参皂苷Re、人参皂苷Rb1的进样量分别在0.22~2.2 ?g、0.22~2.2 ?g、0.26~2.6 ?g范围内与峰面积呈良好的线性关系,相关系数分别为0.999 8、0.999 8、0.999 1;人参皂苷Rg1、人参皂苷Re、人参皂苷Rb1的平均回收率分别为98.04%、96.58%、96.75%。结论 本方法准确、灵敏度高、重复性好,可作为温阳振衰颗粒的质量控制方法。

Abstracts: Objective To establish an HPLC method to determine the contents of ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1 in Wenyang Zhenshuai Granules. Methods The separation was preformed on Agilent TC-C18 column (4.6 mm×250 mm, 5 ?m). The mobile phase consisted of acetonitril-0.05% aqueous solution of phosphoric acid with gradient elution (0–35 min, 19% acetonitrile; 35–58 min, 19%–29% acetonitrile; 58–70 min, 28% acetonitrile; 70–100 min, 29%–40% acetonitrile). The flow rate was 1.0 mL/min; the wavelength of detector was 203 nm; the temperature of column was 35 ℃. Results The calibration curves showed good linearity in the range of 0.22–2.2 ?g (ginsenoside Rg1, r=0.999 8), 0.22–2.2 ?g (ginsenoside Re, r=0.999 8) and 0.26–2.6 ?g (ginsenoside Rb1, r=0.999 1), respectively. The average recoveries of ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1 were 98.04%, 96.58% and 96.75%, respectively. Conclution The method is accurate, hypersensitized and reproducible, which can be applied to the quality control of Wenyang Zhenshuai Granules.

温阳振衰颗粒为湖南省名老中医陈新宇教授临床治疗慢性心力衰竭的经验方,基于现代中医对慢性心力衰竭病机的认识,针对心阳虚衰、瘀血停滞、水饮内停及痰浊不化,组方由人参、茯苓、甘草等7味药组成,具有温阳益气、育阴利尿功效,用于阳虚、水泛型慢性心力衰竭,临床疗效确切[1]。前期药效学研究表明,该方降低基质金属蛋白酶2和9及改善心功能的作用稍优于卡托普利[2];能上调信号调节激酶5(ERK5)蛋白磷酸化的水平,从而激活ERK5信号转导通路[3];可通过调节心力衰竭模型兔心脏功能及降低血浆中内皮素-1的含量,以防止和延缓心力衰竭的进一步恶化[4]。笔者采用HPLC对温阳振衰颗粒中人参皂苷Rg1、人参皂苷Re、人参皂苷Rb1进行含量测定,为控制药品质量和制定质量标准提供参考。
