Objective: To study the chemical constituents of Salvia grandifolia.
Methods: The chemical constituents were isolated and purified by means of chromatographic techniques and their structures were elucidated by spectroscopic methods.
Results: Eleven compounds were isolated from chloroform and ethyl acetate of ethanol extract, and identified as tanshinone Ⅵ( 1),tetrahydrotanshiquinone( 2),tanshinone ⅡB( 3),danshenol B( 4), ursolic acid( 5),2α-hydroxyursolic acid( 6),2α,3α-dihydroxyurs-12-en-28-oic acid( 7),salvianolic acid B(8),3,5-dihydroxycinnamic acid( 9),ethyl 3-( 3,4-dihydrophenyl) lactate( 10) and nepetoidin B( 11).
Conclusion: All of them are isolated from this plant for the first time.
