目的 通过对桑黄药材的超高效液相色谱（UPLC）特征图谱和多组分含量测定结果进行分析，比较并评价野生和不同栽培方式桑黄药材质量。 方法 采用UPLC建立桑黄药材的特征图谱及多组分含量测定方法，并运用聚类分析、正交偏最小二乘法-判别分析（OPLS-DA）方法进行化学模式识别分析。 结果 18批桑黄药材特征图谱有10个共有峰，指认出麦角硫因（峰1）、原儿茶酸（峰2）、原儿茶醛（峰3）、咖啡酸（峰4）、Hispidin（峰5）5个成分，聚类分析、OPLS-DA可将野生品及不同栽培方式桑黄药材明确区分。 结论 段木栽培桑黄较袋料栽培桑黄与野生桑黄更接近，建立的UPLC特征图谱和多成分含量测定方法可为桑黄药材的质量评价提供参考。 Objective To compare and evaluate the quality of wild and different cultivation methods of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai through analysis on UPLC characteristic atlas and multi-component content determination results. Methods UPLC was used to establish the characteristic chromatogram and multi-component content determination method of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai, and clustering analysis, orthogonal partial least squares - discriminant analysis method were used for chemical pattern recognition analysis. Results The results showed that there were 10 common peaks in 18 batches of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai. Five components were identified, erythrothioneine(peak 1), protocatechuic acid (peak 2), protocatechualdehyde (peak 3), caffeic acid (peak 4) and Hispidin (peak 5). HCA and OPLS-DA could distinguish Sanghuang porus vaninii (Ljub.) with different cultivation methods. Conclusion Sanghuang porus vaninii (Ljub.)L.W. Zhou & Y.C. Dai in wood is closer to wild Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai than in substitute cultivation. The UPLC characteristic atlas and multi-component content determination method established in this study can provide reference for the quality evaluation of Sanghuang porus vaninii (Ljub.) L.W. Zhou & Y.C. Dai.
