        摘  要   目的:建立虎掌南星生品及不同工艺炮制品的指纹图谱,并测定其中5种核苷类成分的含量,比较生品与不同炮制品之
        间成分的差异。方法:分别以虎掌南星生品、河南省中药饮片炮制规范制品(简称“《规范》炮制品”)和产地加工炮制一体化新工艺
        炮制品(简称“一体化新工艺炮制品”)(各 12 份)为考察样品,采用高效液相色谱(HPLC)法进行分析[色谱柱为 SymmetryShield
        RP18,流动相为乙腈(A)-0.1%乙酸(B)水溶液(梯度洗脱),流速为 0.8 mL/min,柱温为 30 ℃,检测波长为 270 nm,进样量为 15
        µL]。应用《中药色谱指纹图谱相似度评价系统》(2004A版)软件分别建立3种虎掌南星样品的HPLC指纹图谱并进行相似度评
        价;通过与对照品图谱比较对色谱峰进行指认。同时,对其中5种核苷类成分(腺嘌呤、次黄嘌呤、尿苷、黄嘌呤、肌苷)进行定量分
        析,并采用SPSS 21.0软件对36份样品进行聚类分析。结果:指纹图谱及含量测定的方法学考察结果均符合相关要求。3种样品
        与其各自对照指纹图谱的相似度均大于0.990。在虎掌南星生品中确定了22个共有峰,在2种炮制品中均确定了16个共有峰(2
        种炮制品中消失的6个峰相同);指认出了3种样品中均含有的5种核苷类成分,分别为腺嘌呤(3号峰)、次黄嘌呤(7号峰)、尿苷(8
        号峰)、黄嘌呤(9号峰)、肌苷(11号峰)。含量测定结果显示,2种炮制品中5种核苷类成分的总含量均降低,总含量高低排序为生
        品>一体化新工艺炮制品>《规范》炮制品。聚类分析结果显示,36份样品可聚为2类,其中生品单独聚为一类,2种炮制品聚为另
        一类。结论:本研究建立的方法稳定、可行,可用于虎掌南星生品及不同炮制品的质量评价。虎掌南星经炮制后指纹图谱发生了
        明显变化,5种核苷类成分的总含量均降低,但一体化新工艺炮制品中总含量略高于《规范》炮制品。

        ABSTRACT    OBJECTIVE:To establish the fingerprint of raw products and different processed products of Pinellia pedatisecta,
        to determine the contents of 5 kinds of nucleosides,and to compare the differences of components between the raw products and
        processed products. METHODS:P. pedatisecta raw products,processed products by Processing Standard of Chinese Medicine in
        Henan Province(called“Standard processed product”for short)and processed products by new integrated processing technology in
        the production area(called“new integrated processed product”for short)were collected as investigation objects(12 batches of
        each). The determination was performed on SymmetryShield RP18 column with mobile phase consisted of acetonitrile(A)-0.1%
        acetic acid aqueous water solution(B)(gradient elution)at the flow rate of 0.8 mL/min,with the column temperature of 30 ℃,
        the detection wavelength of 270 nm,and the injection volume of 15 µL. HPLC fingerprints of 3 kinds of P. pedatisecta samples
        were established by using Similarity Evaluation System of TCM Chromatographic Fingerprints (2004 A version) ,and the
        similarity of fingerprints was evaluated. The chromatographic peaks were identified by comparing with the reference chromatogram.
        Five nucleosides(adenine,hypoxanthine,uridine,xanthine,inosine)were quantitatively analyzed. SPSS 21.0 software was used
        for cluster analysis of 36 batches of samples. RESULTS:The results of fingerprint and content determination met the relevant
        requirements. The similarity of 3 kinds of sample with their control fingerprint were all greater than 0.990. There were 22 common
        peaks in the raw products of P. pedatisecta,and 16 common peaks were identified in the 2 kinds of processed products(the same 6
                                                           peaks disappeared from 2 kinds of processed products). Five
