Study on purification process of depsides in Salvia miltiorrhiza with macroporous resin / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the technological parameters of the purification process of Depsides in Salvia miltiorrhiza with macroporous resin.</p><p><b>METHOD</b>The adsorptive characteristics and eluting parameters of the process were studied by taking the content of depsides as index.</p><p><b>RESULT</b>85 mL of extractive of depsides (1.25 g x mL(-1)) was purified with a column of macroreticular resin ( Phi30 mm,127 mL) and washed with 4 BV of distilled water, the eluted with 4 BV of 80% ethanol (1% ammonia).</p><p><b>CONCLUSION</b>This process of applying macroporous resin to adsorb and purify depsides in S. miltiorrhiza is feasible.</p>
