摘要: 选择黑龙江省鹤北林业局区域内常见的松针品种为研究对象,利用不同的溶剂萃取其中的黄酮类和多酚类化合物,并测定了其对DPPH自由基的清除效果。结果显示,醇提法获得的松针样品中总黄酮含量、总多酚含量和对DPPH自由基的清除效果明显优于水提法,测定不同品种间活性物质含量和DPPH自由基清除能力的结果显示如下的顺序:红松>落叶松>樟子松。

关键词: 松针, 黄酮, 多酚, DPPH自由基

Abstract: Common varieties of pine needles from Heilongjiang province were selected as the research subject,the flavonoids and polyphenols compound were extracted by different solvents,and DPPH free radical scavenging activities were determined.Results showed that the total flavonoids content,total polyphenol content and DPPH free radical scavenging activities of pine needles extracted by ethanol was better than that by water.The contents of bioactive compounds and DPPH free radicals scavenging activities were significant different between different varieties of pine needles,and showed in following order: Pimcs koraiensis> Larix geelinii>Pinus slverstris.

Key words: pine needles, flavonoids, polyphenols, DPPH free radical
