Abstract:
Lonicerae Japonicae Flos(LJF), a bulk medicinal material, has long been used in clinical settings. The main/Dao-di production areas are Shandong, Henan, and Hebei. However, no systematic study on the difference in volatile components of LJF from different areas is available at the moment. In this study, gas chromatography-mass spectrometry(GC-MS) was used to detect the volatile components in 30 batches of LJF from 3 main production areas. Based on the relative odor activity value(ROAV), the key aroma components were analyzed. Multivariate statistical analysis was performed to analyze the differential components and characteristic aroma components in the samples from the 3 areas. Finally, 113 volatiles were identified from the samples, which were mainly alcohols, esters, acids, aldehydes, ketones, and alkenes. Among the common components of the three areas, linalool, myristic acid, and α-linolenic acid methyl ester had high content. A total of 15 key and 9 modifying aroma components in LJF were determined based on ROAV. The 15 differential components can be used for origin identification. Among them,(E, E)-2,4-decadienal and hexanal contributed a lot to the aroma of LJF from Henan and α-nerol was a characteristic aroma component of LJF in Hebei. In addition, lauryl aldehyde was a biomarker of LJF from Shandong. This study can provide a reference for the origin identification and quality evaluation of LJF.
