ABSTRACT
<p><b>OBJECTIVE</b>To develop a method for the pretreatment of the series of HPD macroporous adsorption resin (MAR).</p><p><b>METHOD</b>The effect of 2% NaOH to pretreatment of the series of HPD MAR was studied by gas chromatography and UV spectrometery.</p><p><b>RESULT</b>The eluting effect by ethanol was better after the MAR was marinated and eluted by 2% NaOH.</p><p><b>CONCLUSION</b>The pretreatment of the series of HPD MAR was after marinated and eluted by 2% NaOH, the series of HPD MAR were eluted by ethanol at 2 BV x h(-1) at 60 degrees C for 3-4 bed volumes (BV). At then the UV absorbance of eluate was 0.2-0.5. Benzene was not detected and the other residues less than 10 mg x L(-1) in eluted-MAR by GC. And the MARs match to the standard of medicine.</p>
