Study on Biological Materials with Flavonoid Active Compounds of Apocynum venetum L

The Apocynum venetum L. of Apocynaceae plant is a traditional Chinese herbal medicine. In this paper, we analyzed qualitatively the active compounds in the aqueous extract from the leaves of Apocynum venetum L. by HPLCMS and HPLCDAD. The aqueous extracts method of the mainly active compounds from dried leaves of Apocynum venetum L. was based on HPLC/DAD coupled to an electrospray ionization (ESI) interface. Overall, 8 constituents were separated and identified, which belong to flavonoids.
