摘 要:目的:测定消癌平丸中通关藤苷H的含量,并考察其稳定性。方法:采用高效液相色谱.蒸发光散射检测器(HPLC-ELSD)法测定消癌平丸中通关藤苷H的含量;分别于下列条件测定消癌平丸中通关藤苷H的含量:(1)温度(25±2)℃、相对湿度(60±10)%,将3批消癌平丸放置0、3、6、9、12个月;(2)温度(30±2)℃、相对湿度(65±5)%,将3批消癌平丸放置O、l、2、3、6个月;(3)温度(40±2)℃、相对湿度(75±5)%,将3批消癌平丸放置0、1、2、3、6个月。结果:通关藤苷H的进样量在0.3902~3.9020μg范围内与峰面积积分值呈良好线性关系(r=0.9980);平均加样回收率为99.03%,RSD=1.75%。通关藤苷H在条件(1)下基本稳定,在条件(2)和(3)下不稳定,其RSD〉3%。结论:采用HPLC-ELSD法测定消癌平丸中通关藤苷H的含量,样品中通关藤苷H与其他色谱峰完全分离,且峰形良好,可作为消癌平丸中通关藤苷H的含量测定方法。稳定性试验结果显示,通关藤苷H在消癌平丸中不稳定,不宜作为消癌平丸的质量控制指标。OBJECTIVE: To determine the contents of tenacissoside H in Xiaoaiping pills, and to investigate the stability of it. METHODS : The contents of tenacissoside H in Xiaoaiping pills were determined by HPLC-ELSD. The contents of tenacissoside H in Xiaoaiping pills were determined under the following conditions: (1) at (25 ± 2)℃, relative humidity of (60 ± 10)%, keeping for 0,3,6, 9, 12 months; (2) at (30±2)℃, relative humidity of (65+5)%, keeping for 0,1,2,3,6 months; (3) at (40±2) ℃, relative humidity of (75 ± 5)%, keeping for 0,1,2,3,6 months. RESULTS:The linear range of tenacissoside H were 0.390 2-3.902 0 μg (r=0.998 0) with an average recovery of 99.03% (RSD=l.75%, n=6). The content of tenacissoside H kept stable under the condition of (1) but was not stable under the condition of (2) and (3). CONCLUSIONS: The method is accurate and feasible, but tenacissoside H can not used as quality control index of Xiaoaiping pills.
