摘要:采用 6 种大孔吸附树脂和半制备液相色谱分离纯化橙皮苷酶解液中的橙皮素单糖苷(hesperetin-7-
O-glucoside,HMG),并通过红外、紫外和 XRD 验证了产物结构,同时采用羟基自由基清除实验探讨其抗氧化
活性。结果表明:HPD300 大孔树脂最适于酶解液中 HMG 的分离,且其对酶解液中主要组分的静态和动态总吸
附量分别为 48.35 和 35.82 mg/g,主要用于分离糖类杂质;以 10 BV 的体积分数 45%乙醇为洗脱剂,洗脱流速
1.2 mL/min,洗提物中 HMG 的质量分数经 HPLC 测定从 80.37%提高到 97.83%;洗提物经半制备液相进一步分
离纯化后得到单体 HMG,最终质量分数可达 98.21%,且 HMG 的羟基自由基清除能力(72.31%±1.00%)略高
于橙皮素,远高于橙皮苷。

Abstract: Hesperetin-7-O-glucoside (HMG) from hesperidin hydrolysate was separated and purified by six
macroporous adsorption resins and high performance semi-preparative liquid chromatography. The
structure of the product was characterized by IR, UV-Vis and XRD. And the antioxidant activity of HMG
was investigated by hydroxyl radical scavenging test. The results showed that HPD300 macroporous resin
was the most suitable resin for the purification of HMG from enzymatic hydrolysis solution. The static and
dynamic total adsorption amounts of HPD300 resin to the main components of enzymatic hydrolysis
solution were 48.35 mg/g and 35.82 mg/g, respectively, which were mainly used for separation of sugar
impurities. The mass fraction of HMG in the eluent was increased from 80.37% to 97.83% using 10 BV of
45% ethanol as eluent at a flow rate of 1.2 mL/min. The final mass fraction of monomer HMG was 98.21%
after further separation and purification by semi-prepared liquid chromatography. And the hydroxyl radical
scavenging capacity of HMG was (72.31%±1.00%), slightly higher than that of hesperetin, much higher
than that of hesperidin.
