摘要

目的：建立真武汤水提液HPLC特征图谱及同时测定方中苯甲酰新乌头原碱、苯甲酰乌头原碱、白术内酯Ⅲ、芍药苷、6-姜辣素5种主要指标成分的方法。方法：采用高效液相色谱法，Phenomenex Luna C18色谱柱（4.6 mm×250 mm，5 μm），流动相0.2%磷酸水（A）-乙腈（B）梯度洗脱，检测波长230 nm，柱温30℃，流速1 mL·min-1，进样量20 μL。结果：建立的特征图谱包含36个共有峰，各峰峰形、分离度好，明确并定量真武汤水提液中5种指标成分，芍药苷（1.410±0.024）g·L-1，苯甲酰新乌头原碱（0.066±0.001）g·L-1，苯甲酰乌头原碱（0.015±0.001）g·L-1，白术内酯Ⅲ（0.028±0.003）g·L-1，6-姜辣素（0.069±0.001）g·L-1。经方法学验证该方法具有良好线性关系芍药苷Y=25.907X+9.741（r=0.999 7）、苯甲酰新乌头原碱Y=15.265X-3.202（r=0.999 5）、苯甲酰乌头原碱Y=15.660X-4.699（r=0.999 1）、白术内酯Ⅲ Y=63.730X-10.740（r=0.999 6）、6-姜辣素Y=21.645X-4.074（r=0.999 5），精密度（峰面积RSD分别为1.72%，1.76%，2.78%，1.20%，1.05%，保留时间RSD分别为0.81%，0.47%，0.43%，0.07%，0.05%），重复性（峰面积RSD分别为1.95%，2.56%，2.93%，2.65%，3.01%，保留时间RSD分别为0.03%，0.19%，0.28%，0.11%，0.12%），稳定性（峰面积RSD分别为1.05%，1.36%，2.89%，2.81%，2.64%，保留时间RSD分别为0.15%，0.12%，0.39%，0.04%，0.08%）和加样回收率（99.85%，101.67%，101.91%，99.82%，101.44%）。结论：建立的真武汤水提液特征图谱可同时对真武汤5种主要指标成分进行分析，可全面评价真武汤水提汤剂的质量。

Abstract

Objective: This study was aimed to estabilish a high-performance liquid chromatography (HPLC) method for HPLC characteristics of aqueous extract of Zhenwu decoction (ZWT) and simultaneous determination of makers-characteristic chromatography

benzoylmesaconine

benzoylaconine

atractylenolide Ⅲ

paeoniflorin and 6-gingerol. Method: The separation was carried out on a Phenomenex Luna C18(4.6 mm×250 mm

5μm) column eluted with mobile phases of acetonitrile(A) and water containing 0.2% phosphoric acid(B) in gradient mode at the flow rate of 1.0 mL·min-1.The column temperature was maintained at 30℃ and the detection wavelength was set at 230 nm. Result: The obtained HPLC characteristics containing 36 common peaks

which were in well shape and high resolution. Five constituents of ZWT were analyzed and quantified paeoniflorin(1.410±0.024) g·L-1

benzoylmesaconine(0.066±0.001) g·L-1

benzoylaconine(0.015±0.001) g·L-1

atractylenolide Ⅲ(0.028±0.003) g·L-1

6-gingerol(0.069±0.001) g·L-1

with the linear range as follows Y=25.907X+9.741 (r=0.999 7)

Y=15.265X-3.202 (r=0.999 5)

Y=15.660X-4.699 (r=0.999 1)

Y=63.73X-10.740 (r=0.999 6)

Y=21.645X-4.074 (r=0.999 5)

respectively. The precision(1.72%
