Study on the monoterpenoids of Sibiraea laevigata(L.)Maxim.
To study the chemical constituents of monoterpenoids from Sibiraealaevigata,the constituents of S.laevigata leaves were separated and purified with chromatographic methods.Five compounds were isolated and identified as sibirmonoside A(1),cimicifugolide A(2),cimicifugolide C(3),kodemarioside A(4)and kodemarioside C(5)through chemical analyses and spectroscopic methods.Compound 1 was a new monoterpene acylglucoside,compounds 2-5 were isolated from the plants of Sibiraea Maxim.for the first time.
