盐地碱蓬中黄酮类物质的提取及抗氧化性研究

A Study of the Extraction of Flavonoids and in Suaeda Salsa

论述了从65%乙醇浸提法从盐生植物—盐地碱蓬中提取黄酮类化合物,得到粗黄酮,并经聚酰胺柱层析得精制黄酮。利用分光光度法测定其总黄酮含量,并通过NBT法对所提取的黄酮类化合物的抗氧化性进行了研究。同时研究表明,盐地碱蓬中黄酮类化合物对猪油的自氧化有一定的抑制作用。

Total flavonoid was extracted from Suaeda salsa by using 65% alcohol, followed by purification with polyamide pole to obtain refined flavonoid. The contents were determined by spectrophotometric methods. The antioxidant property of total flavonoid was studied by NBT. The present study also shows lard autoxidation can has inhibited in some degree by the flavonoid in Suaeda salsa.
