摘 要 目的:优化生脉饮多糖的提取工艺,并探讨生脉饮及其多糖对脾虚模型大鼠肠道功能的调节作用。方法:采用硫酸苯酚
法测定多糖含量,并计算多糖提取率;以此为考察指标,采用单因素试验和正交试验,对生脉饮多糖提取工艺的料液比、提取时间、
提取温度、提取次数进行优化,并进行验证试验。将 80 只雄性 SD 大鼠随机分为空白组,模型组,生脉饮低、中、高剂量组(350、
700、1 400 g/L,按生药量计)和生脉饮多糖低、中、高剂量组(24.5、49、98 g/L,按生药量计),每组10只。除空白组外,其余各组大鼠
均灌胃大黄水煎液10 mL/kg复制脾虚模型,每天1次,连续15 d。自第16天起,空白组和模型组大鼠均灌胃等容水,其余各组大鼠
均灌胃相应药液,每天1次,连续10 d。观察各组大鼠的一般情况,记录体质量,并采用间苯三酚法或酶联免疫吸附测定法检测其
血清D-木糖、胃泌素(GAS)、血管活性肠肽(VIP)含量。结果:生脉饮多糖最优提取工艺为料液比1 ∶ 10(g/mL)、提取时间45 min、
提取温度 80 ℃、提取次数 1 次。验证试验结果显示,3 次提取的多糖提取率分别为 7.43%、7.64%、7.80%(RSD=1.01%,n=3)。
造模后,除空白组外的其余各组大鼠均出现了大便溏稀、体形消瘦、食量减小等症状,且其体质量和血清D-木糖含量均较空白组
显著降低(P<0.01)。末次给药后,各给药组大鼠上述症状均有不同程度的改善,且除模型组外的其余各组大鼠的体质量以及各
组大鼠血清D-木糖含量均较同组造模前或给药前显著增加(P<0.05或P<0.01);与空白组比较,模型组大鼠体质量和血清GAS
含量均显著降低,血清VIP含量显著增加(P<0.01);与模型组比较,生脉饮中剂量组和生脉饮多糖低、高剂量组大鼠体质量以及
生脉饮中、高剂量组和生脉饮多糖低、中剂量组大鼠血清D-木糖、GAS含量均显著增加,生脉饮各剂量组和生脉饮多糖低、中剂量
组大鼠血清VIP含量均显著降低(P<0.05或P<0.01)。结论:优化的生脉饮多糖提取工艺稳定、可行。生脉饮及其多糖可有助于
恢复脾虚模型大鼠的肠道功能,这种作用可能与其调节肠道GAS、VIP等因子分泌有关。

ABSTRACT OBJECTIVE:To optimize the extraction technology of Shengmaiyin polysaccharide, and to investigate the
regulation effects of Shengmaiyin and its polysaccharide on intestinal function of spleen deficiency model rats. METHODS:The
contents of polysaccharide were determined by phenol-sulfuric acid method,and the extraction rate of polysaccharide was
calculated. Using extraction rate of Shengmaiyin polysaccharide as investigation index,singel factor and orthogonal tests were used
to optimize material-liquid ratio,extraction time,extraction temperature and extraction times of Shengmaiyin polysaccharide.
Validation test was also conducted. Totally 80 male SD rats were randomly divided into blank group,model group,Shengmaiyin
low-dose,medium-dose and high-dose groups(350,700,1 400 g/L,by crude drug),Shengmaiyin polysaccharide low-dose,
medium-dose and high-dose groups(24.5,49,98 g/L,by crude drug),with 10 rats in each group. Except for blank group,other
groups were given Rheum palmatum water decoction 10 mL/kg to induce spleen deficiency model,once a day,for consecutive 15
d. Since the 16th day,blank group and model group were given isovolumic water intragastrically,while other groups were given
corresponding drugs,once a day,for consecutive 10 d. The general status of rats and body weights were recorded in each group.
The serum contents of D-xylose, gastrin (GAS) and
