摘　　要：首次采用超高效合相色谱-光电二级阵列管-四级飞行时间质谱联用技术(UPC^(2)-PDA-Q-TOF/MSE)建立定性和定量方法,对茯苓不同药用部位(茯苓皮、赤茯苓、茯苓、茯神)进行质量评价。利用UPC^(2)-PDA从茯苓类药材中共检测到18个色谱峰,结合主成分分析(PCA)和偏最小二乘判别分析(PLS-DA)对4个药用部位进行比较,结果表明不同药用部位成分差异较大,并筛选出茯苓新酸A、茯苓新酸B、去氢齿孔酸、松苓新酸为主要三萜酸类差异化合物。进一步结合茯苓类药材中的共有活性成分猪苓酸C,采用UPC^(2)-PDA法建立了茯苓类药材中上述5种三萜酸类化合物的含量测定方法。该方法可使5个三萜酸成分在15 min内达到基线分离,有机试剂甲醇的用量仅为HPLC方法的3.63%。以5种三萜酸成分为指标,茯苓不同药用部位中三萜酸含量由高到低依次为茯苓皮、赤茯苓、茯神和茯苓。本实验所建立的方法具有简便、快速、节省溶剂等优点,采用环境友好型气体二氧化碳为流动相,在减少环境污染方面具有独特优势,可为茯苓药材及其相关产品开发和标准制定提供参考。Qualitative and quantitative methods were used to establish the quality of different medicinal parts of Poria cocos(Poriae Cutis,rubra Poria,white Poria,Poria cum Radix Pini)by using ultra-performance convergence chromatography coupled with photo-diode array and quadrupole time-of-flight mass spectrometry(UPC^(2)-PDA-Q-TOF/MSE).A total of 18 chromatographic peaks were detected from Poria cocos by UPC^(2)-PDA.Principal component analysis(PCA)and partial least squares discriminant analysis(PLS-DA)were used to compare the four medicinal parts.The results showed that there were significant differences in the components of different medicinal parts,and the main triterpenoic acids were poricoic acid A,poricoic acid B,dehydroeburicoic acid,and dehydrotrametenolic acid.When combined with the common active component polyporenic acid C,a method for determination of five triterpenoic acids in different parts of Poria cocos was established.These components could be separated within 15 min,and the amount of methanol was 3.63%of that of HPLC method.Taking the five triterpenoid acids as an index,the content of triterpenoid acids in different parts of Poria cocos from high to low were Poriae Cutis,rubra Poria,white Poria and Poria cum Radix Pini.The method is simple,rapid,and uses minimal solvent.The mobile phase of environment-friendly gas carbon dioxide has unique advantages in reducing environmental pollution,which can provide a basis for the development and standard formulation of Poria cocos and its related products.
