摘要

目的

优化铁皮石斛多糖的提取工艺，初步研究其对小鼠急性肺损伤（ALI）的改善作用。

方法

以铁皮石斛为原料，采用超声辅助热水浸渍法提取铁皮石斛多糖；以铁皮石斛多糖提取率为响应值，通过单因素实验和Box-Behnken响应面法优化料液比、提取时间、提取温度。通过脂多糖诱导建立ALI小鼠模型，以醋酸泼尼松（5 mg/kg）为阳性对照，考察低、中、高剂量铁皮石斛多糖（50、100、200 mg/kg）对模型小鼠肺湿/干重比和肺组织病理形态（苏木精-伊红染色、Masson染色）的影响。

结果

铁皮石斛多糖的最优提取工艺为料液比1∶25（g/mL），提取时间1 h，提取温度58 ℃；该工艺所得铁皮石斛多糖的平均提取率为37.75%（RSD＝1.12%，

＝3），与预测值（38.63%）的相对误差为2.28%。与模型组比较，阳性对照组和铁皮石斛多糖各剂量组小鼠的肺湿/干重比均显著降低（

＜0.05或

＜0.01），肺组织病理变化（肺泡结构严重破坏，肺泡间隔明显增宽，大量炎症细胞浸润及成纤维细胞增生）均有不同程度缓解。

结论

优化的铁皮石斛多糖提取工艺可行，且所得的铁皮石斛多糖对小鼠ALI有一定的改善作用。

Abstract

OBJECTIVE

To optimize the extraction process of polysaccharides from

Dendrobium officinale，

and preliminarily study its effect on acute lung injury （ALI） in mice.

METHODS

Using

D. officinale

as raw material， the polysaccharides were extracted from

D. officinale

by ultrasonic-assisted hot water immersion. Using the extraction rate of

D. officinale

polysaccharides as response value， the single-factor experiments and Box-Behnken response surface method were used to optimize the ratio of material to liquid， extraction time and extraction temperature. ALI mice were induced by lipopolysaccharide. Using prednisone acetate （5 mg/kg） as the positive control， the effects on the mass ratio of wet and dry lung and pathological changes of lung tissue （HE staining and Masson staining） of low-dose， medium-dose and high-dose

D. officinale

polysaccharides （50，100，200 mg/kg） were investigated.

RESULTS

The optimal extraction technology of

D. officinale

polysaccharides was as follows： the ratio of material to liquid was 1∶25 （g/mL）， the extracting time was 1 h， and the extracting temperature was 58 ℃. Under these conditions， the average extraction rate of

D. officinale

polysaccharides was 37.75% （RSD＝1.12%，

＝3）， the relative error of which with predicted value （38.63%） was 2.28%. Compared with the model group， the ratios of wet and dry lung in the positive control group and

D. officinale

polysaccharides groups were all decreased significantly （

＜0.05 or

＜0.01）， and the pathological changes in lung tissue （severe destruction of alveolar structure， significant widening of alveolar septa， extensive infiltration of inflammatory cells and proliferation of fibroblasts） were alleviated to varying degrees.

CONCLUSIONS

The optimal extraction process of

D. officinale

polysaccharides is feasible； the obtained polysaccharide extract has a certain improvement effect on ALI in mice.
