After homogenate and centrifugation, the fat existing in liver was removed by diethyl ether. Then, the pH of the remaining aqueous layer was adjusted to 11.6 and clenbutamol was extracted using diethyl ether. The mobile phase component A was 50mmol/L phosphoric acid – 30mmol/L triethylamine and the pH was adjusted to 4.0 with 2mol/L sodium hydroxide.

此外，又将含有盐酸克伦特罗的猪肝用匀浆机匀浆，用1mol/L盐酸溶出其中的盐酸克伦特罗，再用乙醚去除盐酸溶出液中的脂肪后，用2mol/L氢氧化钠调节溶出液pH为11.6，用乙醚萃取其中的克伦特罗。

The chloroform layer and the aqueous layer were separated by multiple column chromatography including macroporous resin, silica gel and polyamide column and preparative HPLC. The compounds obtained were identified by mass spectra and NMR data.

大青叶乙醇提取物，用氯仿萃取后得到氯仿层和水层，各层再分别采用硅胶柱、大孔树脂柱、聚酰胺柱、制备液相、葡聚糖凝胶柱层析及重结晶等分离手段进行分离、纯化，并应用化学性质和质谱、波谱法（1H-NMR、13C-NMR、HMBC）鉴定其化学结构。

To continue the previous work from our laboratory, the purpose of this study is to investigate IGFBP-5 gene expression by BP and ripen areca nut extract in NHOKs . The results in this study suggest that BP and rANE exhibited inhibition effects on IGFBP-5 gene expression both on transcription and translation levels in NHOKs .

本研究发现， BP 及老槟榔萃取物对於正常口腔角质细胞中 IGFBP-5基因之表现均有抑制之效果，且此抑制效果不但发生於基因转录阶段，甚至还持续到转译阶段；类似的结果也在 SCC25细胞中观察到。

We use proteomic approach:two-dimensional electrophoresis and mass spectrometry to detect the proteins expression changes modulated by areca nut extracttreatment and attempted to link the correlation between OSCC and areca use.

本研究使用蛋白体学研究方法――二维电泳搭配质谱仪分析法，探讨口腔细胞受槟榔萃取物影响之蛋白质表现的改变，期望藉由高产能的策略探讨槟榔与口腔癌间的相关性。

The viability of SAS cells decreased obviously because of the raised of the ANE and arecoline, especially in the concentration of 800 ug/ml and 0.8 mM respectively.
