[Research progress on chemical constituents and pharmacological activities of iridoid glycosides in Lonicera japonica]

As a traditional Chinese medicinal material, Lonicera japonica has a long medicinal history. The chemical constituents of Lonicera japonica are complex, mainly including iridoid glycosides, flavonoids, triterpenes, organic acids and volatile oil. Iridoid glycosides account for a higher proportion. In addition, modern pharmacological studies have shown that the iridoid glycosides have many pharmacological activities such as antivirus, anti-inflammation, anti-tumor, liver protection and lowering blood sugar. This review intends to systematically summarize the iridoid glycosides identified from Lonicera japonica and their pharmacological activities by searc-hing Chinese and English databases, in order to provide a reference for the further development and utilization of Lonicera japonica and for the improvement of quality standards of medicinal materials.
