摘  要:
研究了葡萄籽中低聚原花青素的提取条件,考察了提取温度,时间,磷酸浓度对提取液总酚含量的影响,并对提取物的溶解性作了分析。结果表明:3%磷酸的乙酸乙酯-水溶液作提取剂,室温下搅拌提取10h的条件最适,所得产物颜色淡,水溶性好,其低聚原花青素提取率大于2.0%,总酚含量大于70%。

摘  要:
The extraction of oligomeric proanthocyanidins(OPC) from grape seeds was studied in this paper. Some factors,including extracting time, extracting temperature and the concentration of phosphoric acid were studied. The optimal conditionswere: ethylacetate-water containing 3% phosphoric acid and stirring at room temperature for ten hours. The yield of oligomericproanthocyanidins was more than 2.0% and the polyphenolic content more than 70%. The sample was grayish and showed goodwater solubility.
