        摘  要   目的:建立同时测定不同采收期赤芍中6种有效成分含量的方法,并探讨其变化规律,以确定最佳采收期。方法:采用高
        效液相色谱法测定样品中没食子酸、儿茶素、芍药内酯苷、芍药苷、苯甲酸、苯甲酰芍药苷的含量并进行主成分分析。色谱柱为
        Thermo C18,流动相为乙腈-0.1%磷酸水溶液(梯度洗脱),流速为1.0 mL/min,检测波长为230 nm,柱温为35 ℃,进样量为10 µL。
        结果:上述 6 种成分的质量浓度线性范围分别为 0.013 2~0.25 mg/mL(r=0.999 2)、0.013 2~0.25 mg/mL(r=0.999 9)、0.026 8~
        0.51 mg/mL(r=0.999 7)、0.42~8.01 mg/mL(r=0.999 2)、0.016~0.31 mg/mL(r=0.999 4)、0.02~0.38 mg/mL(r=0.999 8);定量限分
        别为0.009 3、0.008 5、0.016 3、0.021 7、0.011 3、0.017 4 mg/mL,检测限分别为0.003 3、0.002 7、0.005 4、0.007 3、0.003 8、0.005 9 mg/mL;
        精密度、稳定性、重复性试验的 RSD 均小于 2%;加样回收率为 96.01%~99.43%(RSD=1.23%,n=9)、97.95%~100.45%
       (RSD=0.79%,n=9)、97.98%~100.11%(RSD=0.68%,n=9)、98.83%~100.09%(RSD=0.65%,n=9)、98.58%~100.95%
       (RSD=1.35%,n=9)、96.28%~103.26%(RSD=1.76%,n=9)。赤芍药材(根)中上述6种成分的含量分别为0.016%~0.057%、
        0~0.067%、0.207%~0.640%、2.350%~5.887%、0.030%~0.245%、0.054%~0.381%。5 月 30 日采收的赤芍药材折干率最低
       (约33%),9月15日折干率最高(约49%)。7-10月采收的赤芍叶中没食子酸、芍药内酯苷的含量均高于根部。主成分分析结果
        显示,前2个主成分的方差贡献率分别为71.845%、18.170%,累积方差贡献率为90.015%;综合得分较高的月份为5-6月、9-10
        月。结论:所建含量测定方法简便、准确,重复性、精密度较好,可用于测定不同采收期赤芍药材中6种有效成分的含量测定;赤芍
        药材的最佳采收期为9月30日-10月15日,叶可在7月15日前后采收。

        ABSTRACT   OBJECTIVE:To establish the method for content determination of 6 active ingredients in Paeonia lactiflora during
        different harvest periods,and to investigate its variation rules so as to determine the optimal harvesting period. METHODS:HPLC
        method was adopted to determine the contents of gallic acid, catechin, alibiflorin, paeoniflorin, benzoic acid and
        benzoylpaeoniflorin,and principal component analysis was conducted. The determination was performed on Thermo C18 column with
        mobile phase consisted of acetonitrile-0.1% phosphoric acid aqueous solution(gradient elution)at the flow rate of 1.0 mL/min. The
        detection wavelength was 230 nm,and column temperature was 35 ℃. The sample size was 10 µL. RESULTS:The linear range of
        the above 6 ingredients were 0.013 2-0.25 mg/mL(r=0.999 2),0.013 2-0.25 mg/mL(r=0.999 9),0.026 8-0.51 mg/mL(r=0.999 7),
        0.42-8.01 mg/mL(r=0.999 2),0.016-0.31 mg/mL (r=0.999 4),0.02-0.38 mg/mL(r=0.999 8),respectively. The limits of
        quantification were 0.009 3,0.008 5,0.016 3,0.021 7,0.011 3,0.017 4 mg/mL,and the limits of detection were 0.003 3,0.002 7,
        0.005 4,0.007 3,0.003 8,0.005 9 mg/mL. RSDs of precision,stability and repeatability tests were less than 2%. The recoveries
        were 96.01%-99.43%(RSD=1.23%,n=9),97.95%-100.45%(RSD=0.79%,n=9),97.98%-100.11%(RSD=0.68%,n=
