•研究报告•H S-S P M E-G C-M S结合化学计量法分析陈皮生品及其炮制品挥发性成分韩蔓,江汉美(湖北中医药大学,湖北省药用植物研发中心,武汉430065 )摘要:目的:分析比较陈皮生品及其炮制品的挥发性成分。
方法:采用HS-SPME-GC-MS对陈皮生品及其炮 制品挥发性成分进行提取分析,用面积归一化法计算各成分的相对百分含量,并结合主成分分析和聚类分析。
结果:分别从陈皮生品、清炒陈皮、盐炙陈皮、麸炒陈皮、蜜炙陈皮中鉴定出66、51、52、50、52种挥发性成分,共鉴定出挥发性成分103种,主要为烯类化合物。
陈皮生品及其炮制品含有22种共有挥发性成分,包括a-法尼烯、榄香烯、大根香叶烯D、d-杜松烯等。
主成分分析和聚类分析可将陈皮生品及其炮制品分为3大类,按照挥发性成分综合得分依次为I类(陈皮生品)、m类(清炒陈皮、麸炒陈皮和蜜炙陈皮)、n类(盐炙陈皮)。
结论:陈皮生品及其炮制品挥发性成分的组成和含量有所差异。
同时从挥发性角度看,可将其分为3大类,其中陈皮生品的质量最好。

Methods: The volatile components from raw product and processed products of Citri ReticulataePericarpium were extracted and analyzed by HS-SPME-GC-MS, and the relative percentage content of each component wascalculated by area normalization method, combined with principal component analysis and cluster analysis. Results: 66, 51, 52, 50and 52 kinds of volatile components were respectively identified from Citri Reticulatae Pericarpium, simple stir-frying, stir-fryingwith salt-water, stir-frying with bran and stir-frying with honey. A total of 103 volatile compounds were identified, mainly alkenes.There were 22 kinds of common volatile components, including a -Famesene, (-)- p -elemene, Germacrene D, d-Cadinene, etc..Principal component analysis and cluster analysis could divided the volatile components from raw product and processed productsof Citri Reticulatae Pericarpium into three categories. According to the comprehensive scores of volatile components, they werecategory I(raw product), category ID (simple stir-frying, stir-frying with bran and stir-frying with honey), category I I(stir-fryingwith salt-water). Conclusion: The composition and content of the volatile components from raw product and processed productsof Citri Reticulatae Pericarpium are different. At the same time, from the perspective of volatility, it can be divided into threecategories, among which the quality of raw product is the best.K e y w o r d s:HS-SPME; GC-MS; PCA: Cluster analysis; Citri Reticulatae Pericarpium; Processed products; Volatile componentsF u n d i n g:Special Major Project of Technology Innovation in Hubei Province (N〇.2016ACA146)通信作者:江汉美,湖北省武汉市洪山区黄家湖西路16号湖北中医药大学,湖北省药用植物研发中心,邮编:430065电话:027-********,E-mail: *****************2.仪器C-MAG H S -4型手动固相微萃取装置(德_IK A公司);6890/5973型气相-质谱-计算机联用仪(美国Hewlett-P arkard 公司);65p m 聚二甲基硅氧烷-二乙烯基苯(PDMS/ DVB )萃取纤维头(美国S upelco 公司);顶空瓶(15mL); JY1002型电子天平(上海浦春计量仪器有限公司)。
