        摘  要   目的:建立三叶青藤叶配方颗粒的质量标准,并同时测定其中5种有效成分的含量。方法:采用薄层色谱法(TLC)对三
        叶青藤叶配方颗粒中绿原酸、异荭草苷、异荭草苷-2′-O-鼠李糖苷进行定性鉴别。采用紫外分光光度法测定3批样品中总黄酮(以
        异荭草苷计)含量,并对其粒度、水分、溶化性及装量差异进行检查。以异荭草苷为内参物计算其余成分的相对校正因子,采用一
        测多评法测定样品中新绿原酸、绿原酸、荭草苷、异荭草苷、异荭草苷-2′-O-鼠李糖苷的含量,并与外标法测定结果进行比较。结
        果:绿原酸、异荭草苷、异荭草苷-2′-O-鼠李糖苷TLC图斑点清晰,分离度好,阴性对照无干扰。样品中异荭草苷检测质量浓度的
        线性范围为 7.73~61.82 μg/mL(r=0.999 9);精密度、稳定性、重复性试验的 RSD 均小于 2%;加样回收率为 93.75%~97.85%
       (RSD=1.41%,n=6)。3批样品不能通过一号筛且能通过五号筛的平均百分率分别为1.51%、1.55%、1.29%(n=3),含水量分别
        为4.63%、5.18%、4.03%(n=3);颗粒均在5 min内溶化;装量差异为4.8%~5.0%,均符合2015年版《中国药典》(四部)颗粒剂的
        相关规定。一测多评法测定5种成分质量浓度的线性范围分别为2.325~93 μg/mL(r=0.999 9)、5.125~205 μg/mL(r=0.999 9)、
        1.150~46 μg/mL(r=0.999 3)、2.625~105 μg/mL(r=0.999 9)、4.725~189 μg/mL(r=0.999 9);精密度、稳定性、重复性试验的
        RSD均小于3%;加样回收率分别为99.78%~106.13%(RSD=2.33%,n=6)、95.07%~103.32%(RSD=2.72%,n=6)、97.17%~
        105.43%(RSD=2.98%,n=6)、95.52%~101.33%(RSD=2.46%,n=6)、99.42%~105.56%(RSD=2.34%,n=6)。异荭草苷相
        对于新绿原酸、绿原酸、荭草苷、异荭草苷-2′-O-鼠李糖苷的相对校正因子分别为0.731、0.805、0.821、0.590;一测多评法测得5种成
        分的含量分别为 0.828~1.123、2.379~3.118、0.281~0.880、1.039~1.393、2.121~3.209 mg/g,外标法测得的含量分别为 0.803~
        1.099、2.345~3.085、0.269~0.872、1.039~1.393、2.113~3.201 mg/g;两种方法测定结果比较,差异均无统计学意义(P>0.05)。结

        ABSTRACT    OBJECTIVE:To establish the quality standard of Tetrastigma hemsleyanum stem and leaves dispensing granules,
        and to determine the contents of 5 active ingredients simultaneously. METHODS : Chlorogenic acid, isoorientin and
        isoorientin-2′-O-rhamnoside in T. hemsleyanum stem and leaves dispensing granules were identified by TLC. The total flavonoids of
        the 3 batches granules were determined by UV spectrophotometry (by isoorientin). The granule sizes, moisture contents,
        dissolvability,and content uniformity were determined. Using isoorientin as internal reference,relative correction factors of other
        components were established. QAMS method was adopted to determine the contents of neochlorogenic acid,chlorogenic acid,
        orientin,isoorientin and isoorientin-2′-O-rhamnoside,which were compared with the results of ESM method. RESULTS:TLC
        spots of chlorogenic acid,isoorientin and isoorientin-2′-O-rhamnoside were clear and well-separated,without interference from
        negative control. The linear range of isoorientin were 7.73-61.82 μ g/mL(r=0.999 9). RSDs of precision, stability and
        reproducibility tests were all lower than 2%. The recoveries were 93.75%-97.85%(RSD=1.41%,n=6). The average percentages
