摘要: 采用聚酰胺树脂层析法,考察聚酰胺树脂的静态吸附和解吸附能力、动态吸附和解吸附能力等,对当归藤(Embelia parviflora Wall.)原花青素进行纯化工艺优化,并对纯化后的当归藤原花青素抗氧化能力进行了评价。结果表明,优化后的当归藤原花青素纯化工艺为上样浓度1.88~3.21 mg/mL、上样流速2~3 mL/min、聚酰胺动态比吸附量16.05 mg/g、最佳洗脱流速2~3 mL/min。不同解吸液体积分数的洗脱率表现50%乙醇溶液>70%乙醇溶液> 30%乙醇溶液>95%乙醇溶液。在抗氧化试验中,当归藤原花青素及原花青素对照品对ABTS+·的清除率及总还原力与维生素C接近,但对DPPH·的清除率及超氧阴离子的清除率不及维生素C。

Abstract: The purification process of proanthocyanidins from Embelia parviflora Wall. was studied by using polyamide resin chromatography, and the static and dynamic adsorption and desorption capacities of polyamide resin were investigated. The antioxidant capacity of the purified proanthocyanidins from Embelia parviflora was also evaluated. The results showed that the optimized purification process was as follows: The sample loading concentration was 1.88~3.21 mg/mL, the sample loading flow rate was 2~3 mL/min, the dynamic specific adsorption capacity of polyamide was 16.05 mg/g, and the optimal elution flow rate was 2~3 mL/min. The elution rates of different volume fractions of desorption solutions were: 50% ethanol solution > 70% ethanol solution > 30% ethanol solution > 95% ethanol solution. In the antioxidant test, the scavenging rates of ABTS+· and the total reducing power of proanthocyanidins from Embelia parviflora and the proanthocyanidin reference substance were close to those of vitamin C, but the scavenging rates of DPPH· and superoxide anion were lower than those of vitamin C.
