摘要: 建立了大孔树脂纯化刺玫叶总黄酮的最佳工艺条件。以吸附率、解吸率为主要考察指标,采用静态吸附及解吸、动态吸附及解吸实验,确定了LX36型大孔树脂纯化刺玫叶总黄酮的效果较理想,并对其纯化条件进行了优化。其最佳纯化条件:上样量为m(生药)∶m(树脂)=1∶25,吸附速率为2 BV·h-1,静置15 min,吸附后用2 BV蒸馏水洗脱,再用5 BV的70%乙醇以3 BV·h-1的流速洗脱,在此最佳条件下,其吸附率平均可为9424%,解吸率平均为8859%,纯化后刺玫叶干浸膏中总黄酮含量由原来的821%提高到2512%,树脂富集倍数约为3倍。结果表明,采用LX36型大孔树脂对刺玫叶总黄酮的纯化具有一定效果。

Abstract: The purification technology of total flavonoids(TF) in leaves of Rosa davurica Pall. with macroporous resin was optimized. Applying both static and dynamic absorptiondesorption experiments, the optimum purification conditions with LX36 macroporous resin which offered ideal purification function were determined using absorption ratio and desorption ratio of TS as evaluating indicators. The loading quantity of sample m(crude drugs)∶m(resin), adsorption rate, adsorption time, volume of water, ethanol content, desorption rate, the volume of eluant were 1∶25, 2 BV·h-1, 15 min,2 BV,70%, 3 BV·h-1, and 5 BV respectively, the average absorption and desorption rate were 9424% and 8859%. The purity of TF in extracts could be changed from 821% to 2512%, which offered about 3 times enrichment with this type of resins. The experimental results have shown that LX36 macroporous resin was fit for the purification of TS in leaves of Rosa davurica Pall.

 Key words: leaves of Rosa davurica Pall.; macroporous absorption resin; flavonoids; purification
