        10.83、0.27~73.40 μg/g。党参炔苷含量由高到低为党参>川党参>素花党参>洛党参;丁香苷为党参>素花党参>川党参,在洛
        党参中未检出;苍术内酯Ⅰ为素花党参>洛党参>党参>川党参;苍术内酯Ⅱ为党参>素花党参,在川党参和洛党参中未检出;苍
        术内酯Ⅲ为党参>素花党参>洛党参>川党参。6~10月采收的党参药材中均以党参炔苷含量最高;6~10月苍术内酯Ⅰ含量均
        较低;8 月苍术内酯Ⅱ未检出;9 月苍术内酯Ⅰ、苍术内酯Ⅱ含量较低,且丁香苷、苍术内酯Ⅱ在部分样品中未检出。结论:所建
        HPLC法操作简单、准确、灵敏度高、重复性好,可用于同时测定党参药材中5种有效成分的含量;不同品种及采收期党参药材中5
        种有效成分含量存在较大差异。

        ABSTRACT    OBJECTIVE:To establish a method for simultaneous determination of the contents of codonopatin,syringin,
        atractylenolide Ⅰ ,atractylenolide Ⅱ and atractylenolide Ⅲ ,and to compare the contents of above 5 components in different
        varieties and harvesting periods of Codonopsis Radix. METHODS:HPLC method was used. The column was Inertsil ODS-3 with
        mobile phase consisted of acetonitrile-water(gradient elution)at the flow rate of 0.8 mL/min. The detection wavelengths were 210
        nm (codonopatin),220 nm (syringin,atractylenolide Ⅱ ,atractylenolide Ⅲ),276 nm (atractylenolide Ⅰ). The column
        temperature was set at 30 ℃ ,and the sample size was 20 μ L. RESULTS:The linear range of codonopatin,syringin,
        atractylenolide Ⅰ,atractylenolide Ⅱ and atractylenolide Ⅲ were 44.30-886.00 μg/mL(r=0.999 7),6.50-130.03 μg/mL(r=0.999 6),
        4.47-89.46 μg/mL(r=0.999 5),2.53-50.50 μg/mL(r=0.999 4),5.64-112.80 μg/mL(r=0.999 5);the limits of quantification
        were 2.446 0,0.168 0,0.248 1,0.065 7,0.099 8 μg/mL,and detection limits were 1.352 0,0.067 2,0.005 4,0.006 3,0.007 3
        μ g/mL;RSDs of precision,stability (24 h),repeatability and durability tests were all less than 2% ;the recoveries were
