Chemical constituents of Salvia cavaleriei Levl.var.erythrophylla (Hemsl.) Stib

Aim To investigate the chemical constituents of Salvia cavaleriei Levi. var. erythrophylla （Hemsl.） Stib. Methods Compounds were isolated by silica gel column chromatography and Sephadex LH-20 gel column chromatography, and the structures were identified by spectral analysis. Result Five compounds were identified as 3β, 6β, 23-trihydroxyolean-12-en-28-oic acid （1）, ursolic acid （2）, n-heptadecanoic acid （3）, n-octadecanoic acid （4）, and β-sitosterol （5）. Conclusion Five compounds were isolated from the plant for the first time.

紫背鼠尾草总提物抗炎镇痛作用的研究

目的:研究唇形科鼠尾草属植物紫背鼠尾草的抗炎镇痛等药理活性。方法:通过二甲苯致小鼠耳肿胀、鸡蛋清致大鼠足趾肿胀、醋酸致小鼠扭体和热刺激小鼠等4种药理模型对紫背鼠尾草乙醇总提取物进行抗炎镇痛的研究。结果:在抗炎药理模型中,实验结果显示紫背鼠尾草乙醇总提取物在200mg/kg时具有显著的抗炎作用;在镇痛药理模型中,实验结果表明,紫背鼠尾草乙醇总提取物在剂量200～400mg/kg时具有较明显的镇痛作用,在100mg/kg时作用不太明显,显示出镇痛作用随剂量的增加而增强。结论:紫背鼠尾草乙醇总提取物抗炎镇痛作用显著,说明了紫背鼠尾草具有抗炎镇痛的功效,为该植物进一步的开发利用提供药效学资料。
