The dried heartwood of this plant is used as a traditional ingredient of food, red dyes, and folk medicines in the treatment of diarrhea, dysentery, tuberculosis, skin infections, and inflammation. Brazilin is the major active compound, which has exhibited various phar- macological effects, including anti-platelet activity, anti-hepatotoxicity, induction of immunological tolerance, and anti-inflammatory and antioxidant activities. The present study aimed to evaluate the antioxidant activity and expression of antioxidant enzymes of C. sappan L. extract and its major compound, brazilin, in human epidermal keratinocytes exposed to UVA irradiation. Our results indi- cated that C. sappan L. extract reduced UVA-induced H202 production via GPX7 activation. Moreover, brazilin exhibited anfioxidant effects that were similar to those of C. sappan L. via glutathione peroxidase 7 （GPX7）, suggesting that C. sappan L. extract and its natural compound represent potential treatments for oxidative stress-induced photoaging of skin.展开更多
目的：通过研究巴西苏木素在大鼠体内的代谢产物,探析其代谢途径。方法：采用UPLC-Q-TOF-MS/MS对灌胃巴西苏木素（30 mg·kg^-1）后大鼠的生物样品（粪便、尿液、血浆、胆汁）进行分析,流动相0.1%甲酸水溶液-乙腈梯度洗脱,流速0.4 m...目的：通过研究巴西苏木素在大鼠体内的代谢产物,探析其代谢途径。方法：采用UPLC-Q-TOF-MS/MS对灌胃巴西苏木素（30 mg·kg^-1）后大鼠的生物样品（粪便、尿液、血浆、胆汁）进行分析,流动相0.1%甲酸水溶液-乙腈梯度洗脱,流速0.4 m L min^-1,电喷雾离子源,负离子模式,信息依赖性采集模式进行检测,离子喷雾电压-4.5 k V,离子源温度500℃,碰撞电压100 e V,碰撞能量-35 e V,锥孔气流50 L·h^-1,m/z 100-1 100,使用Peak View 1.2软件进行数据处理,提取给药样品的总离子流图谱与空白生物样品对比,通过保留时间、精确相对分子质量及二级质谱的比较与分析,筛选并鉴定其可能的代谢产物。结果：共检测出23个代谢产物,这23个代谢产物是巴西苏木素在大鼠体内甲基化、脱氧、缩氢、羧酸化、水合作用、硫酸化、葡糖糖醛酸化后产生的,其中以硫酸化、葡糖糖醛酸化为主。结论：本实验首次对巴西苏木素在大鼠体内的代谢情况进行研究,能够为该药物的药效学和药理学研究提供一定的物质基础。展开更多
