摘要: 目的:探讨地参多糖不同醇沉组分的制备工艺,考察其对高糖诱导大鼠肾小球系膜细胞(HBZY-1)的影响。方法:地参
水提液经脱蛋白、大孔树脂柱层析分离,得地参粗多糖,对地参粗多糖进行分级醇沉获得待测组分,以高糖诱导HBZY-1为模
型细胞进行体外活性测试。结果:得到的3个不同醇沉组分(LLP-30%、LLP-60%、LLP-90%)在0.25~4.00 mg/mL浓度下,对正
常HBZY-1细胞均无毒性;LLP-60%、LLP-90%对高糖诱导HBZY-1细胞的增殖具有显著抑制作用(P<0.01),且能促进细胞超
氧化物歧化酶含量上升,丙二醛和活性氧含量降低。结论:地参多糖组分的提取和分离制备工艺切实可行,其中活性组分
LLP-90%不仅含量最高,而且抑制高糖诱导HBZY-1细胞的增殖及缓解细胞氧化应激效果最为显著,为地参作为糖尿病肾病
功能性食品开发提供基础。

Abstract: Objective: To investigate the preparation process of Lycopus lucidus polysaccharides (LLP) with different ethanol
precipitation fractions and evaluate their effects on high glucose-induced rat glomerular mesangial cells (HBZY-1). Methods: The
crude LLP was obtained by deproteinization and macroporous resin column chromatography, and the components were obtained by
fractional ethanol precipitation. The activity of high glucose-induced HBZY-1 cells was tested in vitro. Results: Three different
ethanol precipitation fractions (LLP-30%, LLP-60%, and LLP-90%) showed no toxicity to normal HBZY-1 cells at concentrations
ranging from 0.25 to 4.00 mg/mL. LLP-60% and LLP-90% exhibited significant inhibitory effects on the proliferation of high glucoseinduced
HBZY-1 cells (P<0.01) and promoted the content of superoxide dismutase while reducing the contents of malondialdehyde
and reactive oxygen species. Conclusion: The extraction, separation and preparation process of LLP are feasible, and the active
component LLP-90% not only has the highest content, but also exhibits the most significant effects on inhibiting the proliferation of
high glucose-induced HBZY-1 cells and alleviating cellular oxidative stress, which provided the basis for the development of L.
lucidus as a functional food of diabetic nephropathy.

Key words: Lycopus lucidus polysaccharides, fractional ethanol precipitation, glomerular mesangial cells, proliferation, oxidative stress
