In order to find new and bioactive compounds, the chemical constituents of the aerial parts of S. orientalis L. were investigated and two new compounds, namely β-D-glucopyranosyl-ent-2-oxo-15,16-dihydroxy-pimar-8(14)-en-19-oic-late (compound 1 ) and [1 (10) E,4Z]-8β-angeloyloxy-9α-methoxy-6α, 15-dihydroxy-14-oxogermacra-1 (10),4,11 (13)-trien-12-oic acid 12,6-1actone (compound 2), as well as five known ent-pimarane diterpenes (compounds 3-7) were isolated. The structures of the two new compounds were identified by their physicochemical properties and spectral analysis, particularly oneand two-dimensional nuclear magnetic resonance spectral methods.展开更多
目的研究稀莶草(Siegesbeckia orientalis L.)甲醇提取物对成纤维细胞增殖及对大鼠创伤的修复作用。方法体外培养乳鼠真皮成纤维细胞,加入不同浓度的稀莶草提取物,MTT法观察其对细胞增殖的影响;制备大鼠切除伤模型,观察稀莶草提...目的研究稀莶草(Siegesbeckia orientalis L.)甲醇提取物对成纤维细胞增殖及对大鼠创伤的修复作用。方法体外培养乳鼠真皮成纤维细胞,加入不同浓度的稀莶草提取物,MTT法观察其对细胞增殖的影响;制备大鼠切除伤模型,观察稀莶草提取物对大鼠实验性创伤的修复作用。结果浓度为50~200μg·mL^-1的稀莶草提取物对成纤维细胞的增殖作用显著;稀莶草甲醇提取物外涂对实验性大鼠皮肤损伤有加速修复作用。结论稀莶草具有促伤口愈合作用,其促修复作用可能与促进成纤维细胞增殖有关。展开更多

文摘目的:研究鸡血藤(Sptholobus suberectus Dunn.),青风藤[Sinomenium acutum(Thunb.)Re-hd.et Wils.],风湿草(Siegesbecuia orientalis L.),苏木(Caesalpinia sappan L.)4种中药治疗类风湿性关节炎(RA)的免疫学机理。方法:采用半定量 RT-PCR 方法检测上述4种中药水提取液刺激 RA 患者外周血单个核细胞(PBMC)后,其γ-干扰素(IFN-γ)、白细胞介素10(IL-10)基因转录的变化。结果:添加中药后,RA 患者外周血 PBMC IFN-γ、IL-10基因的转录均有明显下降。结论:上述4种中药对 RA 患者异常活化的细胞免疫和体液免疫有纠正作用,是治疗 RA 有效的机理之一。
