摘 要:目的探讨不同产地滇黄精高效液相色谱法(HPLC)指纹图谱的建立及其多糖含量的测定。方法取贵州(剑河、安顺、天柱、铜仁、赤水、贵阳及纳雍)、广西百色及四川内江来源的9个批次滇黄精药材各1 g制备供试品溶液,采用DiKMA Platisll ODS C_(18)色谱柱(流动相为乙腈-0.05%磷酸水溶液、梯度洗脱,流速1 mL/min,柱温35℃,进样量20μL,检测波长203 nm)建立滇黄精HPLC指纹图谱,并采用相似度评价、主成分分析及聚类分析等方法评价不同产地滇黄精的质量;采用蒽酮-硫酸法测定各批次滇黄精的多糖含量。结果建立了9批滇黄精的HPLC指纹图谱,共确认12个共有峰;9批不同产地的滇黄精多糖含量均大于7%,含量顺序为贵州剑河>贵州安顺>贵州天柱>贵州铜仁>贵州赤水>贵州贵阳>贵州纳雍>广西百色>四川内江;相似度结果显示,四川内江、贵州贵阳及广西百色的相似度分别为0.762、0.809及0.846,贵州其余地区滇黄精的相似度≥0.853;主成分分析结果显示共得到3个主成分因子,聚类分析结果表明滇黄精被分为3类,且滇黄精多糖含量≥7.16%。结论本研究建立的滇黄精HPLC指纹图谱及黄精多糖成分含量的测定方法简便可行,准确可靠。Objective To investigate establishment of high performance liquid chromatography(HPLC)fingerprints and determination of polysaccharides content in Polygonatum kingianum from different origins.Methods Nine batches of Polygonatum kingianum(1 g)from Guizhou(Jianhe,Anshun,Tianzhu,Tongren,Chishui,Guiyang,and Nayong),Baise Guangxi,and Neijiang Sichuan sources were taken to prepare the test solution(1 g from each origin).The separation was performed on a DiKMA Platisll ODS C_(18)(250 mm×4.6 mm,5μm)column(with acetonitrile-0.05%phosphoric acid aqueous solution as mobile phase in gradient elution at a flow rate of 1 mL/min and a column temperature of 35℃ with an injection volume of 20μL and a detection wavelength of 203 nm)to establish HPLC fingerprints of Polygonatum kingianum extracts;the quality of Polygonatum kingianum from different origins was evaluated by similarity evaluation,principal component analysis and cluster analysis;the content of polysaccharides of Polygonatum kingianum from each batch was determined by anthrone-sulfuric acid method.Results HPLC fingerprints were established for nine batches of Polygonatum kingianum,and a total of 12 common peaks were identified.The polysaccharide content in all nine batches from different sources exceeded 7%.Among them,the descending order of polysaccharide content was as follows:Jianhe Guizhou>Anshun Guizhou>Tianzhu Guizhou>Tongren Guizhou>Chishui Guizhou>Nayong Guizho u>Baise Guangxi>Neijiang Sichuan.The similarity analysis results indicated that the similarities between Neijiang Sichuan,Guiyang Guizhou and Baise Guangxi were 0.762,0.809,and 0.846,respectively;while the similarity of Polygonatum kingianum between other areas in Guizhou province were≥0.853.Furthermore,three principal component factors were obtained using principal component analysis.Cluster analysis revealed that Polygonatum kingianum could be categorized into three distinct groups and content of polysaccharides of Polygonatum kingianum were≥7.16%.Conclusion The method of HPLC fingerprints and
