目的 优选甘草制巴戟天Morindae Officinalis RadixPraeparata的最佳炮制工艺,并考察其炮制前、后总寡糖对雄性小鼠睾丸支持细胞(TM4)氧化损伤的保护作用。方法 采用多指标-响应面法,以D-果糖、D(+)-无水葡萄糖、蔗糖、蔗果三糖、耐斯糖、1F-果呋喃糖基耐斯糖共6种糖类成分的含量为评价指标,利用层次分析法(analytical hierarchy process,AHP)-熵权法计算各评价指标的权重系数和综合评分;进一步利用Box-Behnken设计-响应面法(Box-Behnken design-response surface method,BBD-RSM)考察甘草用量、闷润时间、煎煮时间对甘草制巴戟天炮制工艺的影响,优选最佳炮制工艺;按照最佳炮制工艺制备甘草制巴戟天,并评估甘草制前、后巴戟天总寡糖对H2O2诱导的TM4细胞氧化应激损伤的保护作用。结果 甘草制巴戟天的最佳炮制工艺为100 g生巴戟天饮片,甘草用量8 g,闷润时间1.0 h、煎煮时间35 min。药效实验结果表明,甘草制巴戟天总寡糖可显著增强谷胱甘肽过氧化物酶(glutathione peroxidase,GSH-Px)、过氧化氢酶(catalase,CAT)和超氧化物歧化酶(superoxide dismutase,SOD)活性(P<0.01)、减少丙二醛(malonaldehyde,MDA)含量(P<0.05),且抗氧化应激损伤作用优于生品总寡糖。结论 运用AHP-熵权法结合BBD-RSM优选制巴戟天炮制工艺,结果准确、可行;药效实验结果为巴戟天甘草制的合理性提供实验依据。

Objective To optimize the processing technology of Gancao (Glycyrrhizae Radix et Rhizoma, GRR) processed Bajitian (Morindae Officinalis Radix, MOR) and compare the effects of MOR oligosaccharides on the oxidative damage of testicular support (TM4) cells in male mice before and after processing. Methods A multi-index-response surface methodology was used, with D-fructose, D(+)-glucose, sucrose, kestose, nystose, and 1F-fructofuranosylnystose as evaluation indicators. Analytical hierarchy process (AHP)-entropy weighting method was used to calculate the weight of each indicator and determine the comprehensive score (OD). Furthermore, Box-Behnken design-response surface methodology (BBD-RSM) was used to investigate the effects of GRR dosage ratio, moistening time and decoction time on the processing technology of MOR. The processed MOR was prepared according to the optimal processing technology to evaluate the protective effect of MOR oligosaccharides on oxidative stress damage induced by hydrogen peroxide in male mice testicular support cells. Results The best processing parameters were 100 grams raw MOR and 8 g GRR dosage for moistening for 1 h, decocting time was 35 min. The results of pharmacodynamic experiments demonstrated that GRR processed MOR oligosaccharides had significantly enhanced GSH-Px, CAT and SOD enzyme activities, reduced MDA contents (P < 0.05), and had stronger antioxidative effects than the raw MOR oligosaccharides. Conclusion In this experiment, the AHP-entropy weighting method combined with BBD-RSM was used to optimize the process parameters of GRR processed MOR, which was accurate and feasible. And the results of pharmacodynamic experiments could provide experimental basis for the rationality of GRR processed MOR.
