摘要：

对南酸枣皮进行体外模拟胃肠液消化与溶剂提取，研究不同提取方法对南酸枣皮中总多酚、总黄酮、原花青素释放的影响，并通过透析袋模拟肠道的吸收作用，考察其生物利用率。结果表明：体外消化过程中酚类化合物主要在胃部释放，经模拟胃液消化1 h后，总多酚、总黄酮、原花青素释放量分别为73.72、38.55、37.53 mg/g；肠液消化2 h后，总多酚、总黄酮释放量分别增加10.29 mg/g和8.78 mg/g，而部分原花青素发生分解，降幅为17.87%；透析袋内总多酚、总黄酮、原花青素释放量分别为5.94、5.48、3.21 mg/g，生物利用率分别为7.07%、11.59%和10.42%，因此黄酮类化合物最可能被人体吸收利用。不同处理方法的多酚类化合物的释放量为模拟胃肠液消化＜传统热水浸提＜超声波辅助乙醇提取（化学提取＞中药口服＞直接食用）。

Abstract:

The aim of this research was to access the release of total phenolics, flavonoids and procyandines from
Choerospondias axillaris fruit peel during in vitro simulated gastro-intestinal digestion and solvent extraction, and the
bioavailability of the components were also studied by simulating intestinal adsorption using dialysis. Results indicated
that the phenolic compounds were mainly released in the gastric phase. After digested in simulated gastric juice for 1 h,
the release amount of polyphenols, flavonoids and procyanidins were 73.72, 38.55 and 37.53 mg/g, respectively; after
2 h intestinal digestion, the release amount of polyphenols and flavonoids increased by 10.29 and 8.78 mg/g, respectively,
however, 17.87% of procyandines were degraded. In addition, the contents of polyphenols, flavonoids and procyanidins
in the dialysis bag were 5.94, 5.48 and 3.21 mg/g, and the corresponding bioavailability was 7.07%, 11.59% and 10.42%,
respectively. Therefore, flavonoids are the most available component for human adsorption and utilization. Different
treatment methods released phenolic compound in the order: simulated gastro-intestinal digestion < traditional hot water
extraction < ultrasonic assisted ethanol extraction.
