Abstract:To investigate the main chemical compositions of Verbena officinals L. extract, a qualitative high performance liquid chromatography-photodiode array-high resolution mass spec-trometry ( HPLC-PDA-HRMS) method was established. The structures of the compounds detec-ted were identified by analyzing the chromatographic profiles and the corresponding mass spec-tra obtained by full scan and MSn full scan. Twenty one compounds including iridoid glycosides, flavonoids, triterpenoids, phenylpropanoids and phenolic diterpenoids were identified, and six of them were not reported in other literatures about Verbena officinalis L. extract, such as carnosic acid, carnosol, rosmanol, isorosmanol, rosmarinic acid and acacetin-7-O-rutinoside. This method is simple, rapid, accurate and sensitive. It provides a reliable scientific basis for the identification of the authenticity and quality control of Chinese medicinal materials.
