摘要
利用高效液相色谱和核磁共振波谱仪测定了金银花提取物的HPLC和1HNMR图谱,对金银花提取物的HPLC图谱进行了比较,结果表明金银花提取物的HPLC指纹图谱有很好的相似性;对金银花提取物的1HNMR指纹图谱研究表明,金银花含有其主要有效成分绿原酸的特征峰,同时金银花提取物的1HNMR指纹图谱也有很好的相似性,并具有很好的重现性和高度的特征性。金银花提取物的HPLC和1HNMR指纹图谱可以作为金银花鉴定的相对标准图谱和数据,作为金银花质量鉴别的依据。
The HPLC and ^1HNMR fingerprints of the general characteristic extracts of Flos lonicera were determined by HPLC and PFF-NMR spectrometer, The comparison of HPLC between the general characteristic extracts from the Flos lonicera showed that the HPLC fingerprints of the general characteristic extracts had good repeatability and characteristics. The ^1HNMR fingerprints were systematically assigned and compared with its effective component Chlorogenic acid, and the characteristic peaks were also obtained. The results showed that all the general characteristic extracts displayed the characteristic peaks of Chlorogenic acid. The characteristic peaks of the general characteristic extracts had good repeatability and characteristics. The HPLC and ^1HNMR fingerprints could become the identification criterion of the truth or false of Flos lonicera during the quality identification of Flos lonicera,
