Study on Chemical Constituents from Sibiraea laevigata
Aim:To study the chemical constituents of monoterpenoid from Sibiraea laevigata.Methods:The constituents of Sibiraea laevigata were separated and purified with chromatographic methods.The structures were elucidated by chemical analyses and spectroscopic methods.Results:Six compounds were isolated from the leaves of Sibiraea laevigata,and they were identified as 6β-hydroxystigmast-4-en-3-one(1),stigmast-4-en-3β-ol(2),ergosta-7,22-dien-3β-ol(3),3β,6β,23-trihydroxyolean-12-en-28-oic acid(4),2α,3α-dihydroxyolean-12-en-28-oic acid(5),oleanic acid(6).Conclusion:Compound 1-5 were isolated from the plants of Sibiraea Maxim.for the first time.
