小分子团磁化水提取金花茶活性成分

Extraction of Active Components from Camellia Oleifera Tea by Magnetized Small Molecules Group Water

实验取多个平行样品在相同条件下进行二次蒸馏,测定最终浓缩固体物的提取率以及浓缩液总黄酮和茶多酚的含量。结果表明,小分子团磁化水对金花茶的提取率及浓缩固体物中总黄酮的含量均大于超纯水所得。例如分别用超纯水与小分子团磁化水提取,则所得的固体物质量(mg)依次为14.17/22.48、14.36/21.38、14.17/20.88;总黄酮的质量(mg)依次为1.49/1.95、1.89/2.60、1.48/2.32。如果分别用超纯水与小分子团磁化水提取,则所得的茶多酚的质量(mg)以超纯水为高,它们依次为23.92/19.58、26.73/21.21、27.06/23.96。实验结果提示,利用小分子团磁化水能有效提高金花茶叶中固体物和总黄酮的提取率,但未能提高茶多酚提取率。

The difference extraction rate of active component from fresh camellia oleifera tea was compared by using small magnetized molecule group water and using ultrapure water.In the experiment,several parallel samples were taken to carry out secondary distillation under the same conditions.Determining the extraction rate of the final concentrated solids,And the contents of total flavonoids and tea polyphenols in the concentrated solids.The results showed that the extraction rate and the content of total flavonoids in the concentrated solids of camellia oleifera tea by magnetized small molecular group water were higher than those by ultrapure water.The solids obtained by magnetized small molecular group water and ultrapure water were 14.17/22.48,14.36/21.38,14.17/20.88,respectively;The contents of total flavonoids in solid were 1.49/1.95,1.89/2.60,1.48/2.36 respectively.The mass(mg)of the tea polyphenols obtained by the ultrapure water method and the magnetized small-molecule group water method were higher than those of the ultrapure water method,which were 23.92/19.58,26.73/21.21,and 27.06/23.96,respectively.The experimental results suggest that the use of magnetized small-molecule group water extraction can effectively improve the extraction rate of solids and total flavonoids in camellia oleifera tea,but fails to improve the extraction rate of tea polyphenols.
