摘要:

以五味子(Schisandra chinensis)干果为原料,采用超声辅助纤维素酶酶解法提取五味子多糖,研究五味子多糖的超声辅助酶解工艺与抗细胞氧化应激活性。以多糖得率为指标,采用单因素试验和Box-Behnken响应面试验研究加酶量、超声功率、提取时间和料液比对五味子多糖得率的影响,优化得到五味子多糖最佳超声辅助酶解提取工艺条件;建立脂多糖(LPS)诱导的HepG2细胞氧化应激损伤模型,以丙二醛(MDA)、超氧化物歧化酶(SOD)和活性氧(ROS)水平为指征,研究五味子多糖的抗细胞氧化应激能力。结果表明:五味子多糖的最佳提取工艺条件为加酶量1 420 U·g-1,超声功率500 W,提取时间46 min,料液比1 g∶32 mL,该条件下五味子多糖得率为22.25%;此外,所提取得到的五味子多糖可提高LPS诱导HepG2细胞中的SOD水平,并可降低细胞中MDA的积累量和ROS荧光强度,有效缓解了LPS诱导的HepG2细胞氧化应激反应。优化确立了超声辅助纤维素酶提取五味子多糖最佳工艺条件,发现所提取得到的五味子多糖有良好抗氧化应激能力。

Abstract:

The polysaccharides of Schisandra chinensis were extracted by ultrasonic-assisted cellulase enzymolysis from the dried fruit of S. chinensis as raw material, and the extraction process and anti-oxidative stress activity of S. chinensis polysaccharides were studied. Using polysaccharide yield as index, single factor experiment and Box-Behnken response surface test were used to investigate the effects of enzyme concentration, ultrasonic power, extraction time and solid-liquid ratio on polysaccharide yield of S. chinensis, and the ultrasonic-assisted enzymatic extraction process was optimized. A lipopolysaccharide(LPS) induced oxidative stress damage model of HepG2 cells was established, and the levels of malondialdehyde(MDA), superoxide dismutase(SOD) and reactive oxygen species(ROS) were used as indicators, and the anti-oxidative stress ability of S. chinensis polysaccharides was investigated. The results showed that the optimal extraction conditions as followed: the enzyme concentration was 1 420 U·g-1, the ultrasonic power was 500 W, the extraction time was 46 min, the solid-liquid ratio was 1 g∶32 mL. Under these conditions, the yield of polysaccharides was 22.25%. Moreover, the extracted S. chinensis polysaccharides might improve the SOD level in the LPS-induced HepG2 cells, but reduce the MDA accumulation and ROS fluorescence intensity in the cells, and effectively relieve the LPS-induced oxidative stress in HepG2 cells. The extraction conditions of polysaccharides from S. chinensis were optimized, and it was found that the extracted polysaccharides had good antioxidant stress ability.
