摘要: 芹菜叶富含黄酮类物质,通过浸提、硅胶柱层析、重结晶得到精提物。经HPLC-ESI-MS鉴定,其中主要成分为芹菜苷,纯度达93.22%。芹菜苷具有强抗氧化性,总抗氧化活性为1.1 U/μg;能够有效清除亚硝基(SC2516.53μg/ml);螯合亚铁离子(SC50 8.53μg/ml);能够增强油脂稳定性,抑制油脂自由基,对豆油和猪油的保护因子分别为2.13、2.14。

Abstract: Leaf of Apium graveolens L. var. dulce is rich in flavonoids. The refined extract was obtained by means of successive extraction,silica gel column chromatography and recrystallization. According to identification results with HPLC-ESI-MS,the refined extract mainly consists of apiin with 93 % of purity. The total antioxidant activity of the refined extract is 1.1 U/μg,SC25(the quarter-maximal scavenging concentration) for scavenging nitrite is 16.53μg/ml and SC50(the half-maximal scavenging concentration) for scavenging ferrous is 8.53 μg/ml. Moreover,it can enhance the stability of lipids and inhibit lipid free radicals,and the protection factors(PFs) to bean oil and lard are 2.13 and 2.14,separately.

Key words: leaf of Apium graveolens L. var. dulce, apiin, nitrite, ferrous, lipid free radicals
