  Chronic renal failure (CRF) is defined as a progressive and irreversible loss of renal function and associated with inflammation and oxidative stress.Salvia miltiorrhiza (SM) is an important Chinese herb used in traditional Chinese medicine with notable effects on CRF.Here, we showed that the ethanol extract (SMEE) and water extract (SMWE) of SM significantly inhibited the elevation of serum creatinine (Scr), blood urea nitrogen (BUN), urine protein (UP) and indoxyl sulfate (ISF) in adenine-induced CRF rats, especially SMEE.Moreover, SM extracts obviously improved the symptoms of glomerular and tubular atrophy, focal calcium deposits, interstitial fibrosis, interstitial inflammation,and renal tissues.Fifty-nine metabolites (thirteen in plasma, twenty-seven in urine and nineteen in kidney tissue) were up-regulated or down-regulated and contributed to CRF progress.After treatment of SM extracts, the altered metabolites were restored back to normal level.These potential biomarkers underpinning the metabolic pathways are including phenylalanine metabolism, pyrimidine metabolism,purine metabolism and tryptophan metabolism.Furthermore, SM extracts prevent epithelial-mesenchymal transition (EMT) of Human renal tubular epithelial (HK-2) cell by inhibiting NADPH oxidase/ROS signaling pathway and tanshinone ⅡA (DⅡA), salvianolic acid B (SAB) were the main bioactive compounds, providing a powerful supports to develop a new therapeutic agent for CRF.

关于冬虫夏草的重金属砷超标问题,困扰中药业界和消费者已经很长一段时间。我们通过到西藏、青海、四川、雪南等不同產地采集原产地样品,以及在全国各地随机收集冬蟲夏草商品檬品50多件,進行了重金属含量檢测,发现所有天然冬虫夏草重金属砷均超过2mg/kg(2ppm)。我们对收集带泥土的新鲜虫草,同时检测泥土和虫草中的重金属砷,发现生长在高砷含量土壤中的虫草,其砷含量与土壤中的砷含量成正比例增高。冬虫夏草是一
目的:研究香茶菜属几种植物显微特征差异。方法:应用表面制片对香茶菜属4种常见植物的叶片进行显微观察。结果:几种香茶菜属植物叶片上腺毛腺柄的长短、腺头的细胞数目,非腺毛的长短及细胞数均有明显差异,提供了鉴定图表和鉴别检索表。结论:提供了香茶菜真伪鉴别的新依据。
由于具有很高的营养价值、美味可口的果实、以及丰富的药用成分,近年来,酸浆属植物的商业价值在全球范围内逐步受到人们的重视。但是酸浆属植物形态学性状相似,鉴定比较困难;同时其系统发育关系背景比较混乱。这给酸浆属种质资源的正确利用和保护带来了困难。本文综述了DNA分子标记技术在酸浆属植物鉴定、遗传多样性及系统发育中的研究进展,目的是为酸浆属植物的物种鉴别、遗传资源保护及合理利用奠定重要基础。

以不同基源肉苁蓉种子为试材进行冰冻切片。种子经过前处理、冷台固定、冷冻切片、展片、染色、观察并拍照等步骤。结果表明当冷台温度为-20℃;OCT包埋剂冷冻5~10min;切片厚度为8~15 μm时,可以获得较清晰的种子横(纵)切面图,切片组织完整性和图片清晰度效果较好。
目的:建立商洛桔梗药材的高效液相色谱(HPLC)指纹图谱,为商洛桔梗药材的道地性研究提供可靠资料.方法:采用HPLC法测定来源于商洛7个县(区)的39个桔梗样品.色谱条件:Hypersil C18柱(250 mm×4.6 mm,5μm),以乙腈和H3PO4混合溶液作为流动相,采用梯度洗脱方式,流速为0.5 mL/min,检测波长为210 nm,柱温30℃.结果:建立了39批桔梗药材的HPLC指纹图

基于HPLC和活性筛选相结合的复杂体系中活性成分快速识别和鉴定的模式主要有两种:(1)生物活性筛选-HPLC分析,采用各种生物活性材料(例如酶、载体蛋白、细胞膜等)作为固定相的一种新兴色谱技术,中药提取物先与靶标分子(自由基、酶、蛋白、细胞等)反应,之后进行HPLC分析,由于不同成分作用程度的差别或与靶标具有不同的结合性能,而在固定相上表现出不同保留性能,可实现中药生物活性筛选和化学分离分析同步,
大枣为鼠李科植物枣(Ziziphus jujuba Mill.)的干燥成熟果实.属药食同源,收载于2015年版《中国药典》,其味甘、性温,具有补中益气,养血安神的功效.全世界有超过1000种的大枣栽培品种.借助一维核磁共振氢谱和多元变量分析,我们通过对蔗糖,α及β葡萄糖,果糖,丙氨酸,苏氨酸,缬氨酸,甲酸,富马酸,乙酸,胆碱的含量进行主成分分析,发现14份大枣样品可以分成两组,与大枣的采集来源一致
