    Abstract Phytochemical investigations from the roots of Cynanchum stauntonii led to obtain four new C 21 steroidal glycosides ( 1 – 4 ) and one known compound stauntoside F ( 5 ). Their chemical structures were characterized by sophisticated analyses of IR, HRESI-TOF-MS, 1D, and 2D-NMR data, together with chemical methods, which showed interesting 13,14:14,15-disecopregnane-type skeleton or 14,15-secopregnane-type

    Nine new C21 steroidal glycosides, named cynawilfosides A–I (1–9), along with 12 known compounds were isolated from the roots of Cynanchum wilfordii. The structures of the new compounds were elucidated by spectroscopic analysis and chemical methods. The five major components, cynawilfoside A (1), cynauricoside A (11), wilfoside C1N (16), wilfoside K1N (17), and cyanoauriculoside G (18), exhibited significant
    九个新的C 21甾体糖苷,命名cynawilfosides A-I(1 - 9)中,用12种已知化合物沿从根部分离牛心甙。通过光谱分析和化学方法阐明了新化合物的结构。五个主要成分,cynawilfoside A(1),cynauricoside A(11),wilfoside C1N(16),wilfoside K1N(17)和尿苷G(18),在最大电击(MES)诱导的小鼠中显示出显着的保护活性。癫痫发作模型,ED 50值分别为48.5、95.3、124.1、72.3和88.1 mg / kg。

    Six new steroidal glycosides, named stauntosides O-T (1–6), along with eight known compounds (7–14), were obtained from the 95% aqueous ethanol extract of the roots of Cynanchum stauntonii. Their chemical structures were elucidated by IR, HR ESI-MS/MS, 1H- and 13C NMR, 1H-1H COSY, HSQC, HSQC-TOCSY, and HMBC spectroscopic analyses, which showed interesting 13,14:14,15-disecopregnane-type or 14,15-secopregnane-type
    六个新的甾体糖苷,命名stauntOSides OT(1 - 6)中,用8种已知化合物(沿7 - 14),从根的95%乙醇溶液的提取物得到柳叶白前。通过IR,HR ESI-MS / MS,1 H-和13 C NMR,1 H- 1 H COSY,HSQC,HSQC-TOCSY和HMBC光谱分析阐明了它们的化学结构,结果显示有趣的13,14:14, 15-二癸基癸二型或14,15-二癸基癸烷型C 21类固醇糖苷。通过检测诱导型一氧化氮合酶(iNOS)和环合酶2(COX-2)对脂多糖(LPS)刺激的RAW246.7鼠巨噬细胞的抑制作用,研究了糖苷的抗炎作用。我们的结果表明,化合物1,5,8,9,11,和13可以显著抑制iNOS的表达,和化合物5和7可以清楚地减少RAW246.7细胞的COX-2表达LPS刺激的细胞相比,用LPS刺激和未经其他化合物处理。因此,化合物1,5,7-9,11,和1
