STUDIES ON THE CHEMICAL CONSTITUENTS FROM ROOTS OF AGASTACHE RUGOSA

Eleven compounds were isolated from roots of Agastache rugosa and eight of them were identified as maslinic acid (Ⅰ), oleanolic acid (Ⅱ), 3- O- acetyl oleanolic aldehyde (Ⅲ), acacetin (Ⅳ), tilianin (Ⅴ), agastachoside (Ⅵ),daucosterol (Ⅶ) and β-sitosterol (Ⅷ). Compound Ⅸ is a new diterpenoid and its structure was proposed to be 19 (4→3 )abco- 11,14- dihydroxy- 12- methoxy- abieta- 8,11,13, 15- tetraen- 7- one based on spectral data, named dehydroagastol. The studies on Ⅹ and Ⅺ are in progress.
