摘　　要：为建立人工栽培桑黄瓦宁纤孔菌的HPLC指纹图谱,采用化学计量学分析方法对其进行分析和筛选出桑黄的4个标志性成分,并以其中最主要成分Hypholomine B为指标建立含量测定方法。参照2020年版《中国药典》(四部)通则中高效液相色谱法,建立桑黄指纹图谱,利用“中药色谱指纹图谱相似度评价系统2004 A版”评价其相似度,确定共有峰,同时测定桑黄中苯乙烯吡喃酮类成分Hypholomine B的含量。结果表明,建立了10批桑黄的HPLC指纹图谱,共有12个共有峰,相似度均大于0.92。系统聚类分析(HCA)、主成分分析(PCA)和正交偏最小二乘判别分析(OPLS-DA)结果一致,将样品分为两类。在1.25~20.00μg范围内,Hypholomine B的进样量与峰面积具有良好的线性关系(R^(2)=0.9999);精密度、稳定性和重复性试验的相对标准偏差(RSD)值均小于2.0%(n=6);加样回收率为95%~99%,其RSD值为1.48%;10批桑黄样品中Hypholomine B的含量范围为0.15%~0.95%。指纹图谱与HCA、PCA和OPLS-DA相结合可全面地评价桑黄药材质量,该方法稳定、可靠,可为桑黄质量评价提供参考。To establish HPLC fingerprint of cultivated Sanghuangporus(Sanghuang),screen out the signature component of Sanghuangporus through chemical pattern recognition,the content determination method of Sanghuangporus was established based on this index.According to the corresponding methods in the general rules of The Chinese Pharmacopoeia(four parts)in the 2020 edition,the fingerprint of Sanghuangporus was established,and the similarity was evaluated by using the similarity evaluation system of traditional Chinese Medicine Chromatographic Fingerprint 2004 Version A to determine the common peak.The content of Hypholomine B in Sanghuangporus was also determined.HPLC fingerprints of 10 batches of Sanghuangporus were established,with 12 common peaks,and the similarity was greater than 0.92.The results of HCA,PCA and OPLS-DA were consistent,and the samples were divided into two categories.The injection volume of Hypholomine B had a good linear range with its peak area in the range of 1.25-20.00μg(R^(2)=0.9999).The RSD values of precision,stability and repeatability were all less than 2.0%(n=6).The recovery rate was 95%-99%,and the RSD was 1.48%.The content of Hypholomine B in 10 batches of mulberry yellow samples ranged from 0.15%to 0.95%.The fingerprint can be combined with HCA,PCA and OPLS-DA to comprehensively evaluate the quality of Sanghuangporus.The method is stable and reliable,providing reference for the quality evaluation of Sanghuangporus.
