The chemical constituents were isolated by polyamide, silica gel and Sephadex G-Sepharose chromatography purification, and their structures were identified by NMR spectroscopy and other analyses. A total of 10 compounds were obtained and identified as follows： 3-（2-furan）-l-（2-hydroxy-4-methoxy-phenyl）-2-propylene ketone （1）, 2-（2,5-hydroxy-4-methyl phenyl） propionate ethyl ester （2）, methyl tetradec-5-enoate （3）, 1,4-diethylcyclohexane （4）, catechol （5）, methyl-4-hydroxybenzoate （6）, 3-hydroxy- 2-methyl-4-pyrone （7）, 3,8-dihydroxy-2-metyl-chromone （8）, 3β-hydroxy-olean-12-en （9）, 1-monolinolein （10）. Among them, compounds 1 and 2 were new natural products, and 3-10 were isolated from the Cortex Moutan charcoal for the first time. The potential coagulation activities of compounds were evaluated, and compounds 2, 9 and 10 had strong hemostatic effects. While compounds 1 and 8 could significantly activate blood circulation.展开更多
