摘要
A new stigmasterol type natural product,viburodorol A(1),along with eleven known sterols and terpenoids(2–12),were isolated from the aerial parts of Viburnum odoratissimum.The structure of 1 was elucidated on the basis of comprehensive spectroscopic analysis.It’s noteworthy that compound 2,the major constituent of this plant,can signifi-cantly stimulate glucose absorption in insulin resistant HepG2 cells without affecting cell viability.Furthermore,this compound can also restore the glucose absorption in DXMS-induced insulin resistant 3T3-L1 cells.
