标题:Anti-Inflammatory Terpenes From Schefflera Rubriflora C. J. Tseng & G. Hoo With Their Tnf-α And Il-6 Inhibitory Activities
摘要:The 95% Ethanol Extract And Its Etoac And N-Buoh Fractions Obtained From The Leaves And Twigs Of Schefflera Rubriflora C. J. Tseng & G. Hoo Showed Significant Inhibitory Activities (33.6%,35.7% And 40.6%,Respectively) Against Croton Oil-Induced Ear Inflammation In Mice. Bioactivity-Guided Isolation And Separation Gave Eight Previously Undescribed Terpenes Or Terpene Glycosides. Structural Elucidation Was Based On Uv,Ir,And NMR Spectroscopy,Ms,Experimental And Calculated Ecd Data,And Mosher'S Method. To Identify Anti-Inflammatory Components From The Extract,All The Compounds Were Evaluated For Tumor Necrosis Factor-Alpha (Tnf-Alpha) And Interleukine-6 (Il-6) Inhibitory Activities. Four Undescribed Compounds Inhibited Mrna Expression Of Tnf-Alpha And Il-6 With Ic50 Values Of 15.3-52.4 Mu M.
