摘要: 向日葵是世界上著名的油料作物和观赏植物之一,其次生代谢产物具有多种生物医药活性。本文研究了绿原酸、多糖、黄酮和多酚4种次生代谢产物在向日葵各生长阶段的分布和积累情况,结果表明:成熟期的向日葵花盘多糖含量最高为52.2 mg·g-1,开花期的向日葵花盘绿原酸含量最高为2.64 mg·g-1,苗期的叶中黄酮和多酚的含量最高分别为20.94和11.75 mg·g-1。综合考虑这4种次生代谢产物的分布和积累情况,花期的向日葵花盘和现蕾期的叶最具有药用开发价值。

Abstract: Helianthus annuus L. is one of the most famous ornamental plants and the oil crops in the world, its secondary metabolites have various biological and medical activities. We studied the distribution and accumulating regularity of four secondary metabolites-chlorogenic acid, polysaccharides, flavonoids and polyphenols in various growing stages of H.annuus L.. The higest chlorogenic acid content of 2.64 mg·g-1 was in faceplates on flowering stage, the highest polysaccharide content of 52.2 mg·g-1 was in faceplates on maturity stage, and the highest flavonoids and polyphenols contents of 20.94 and 11.75 mg·g-1, respectively, were in leaves on seedling stage. Considering the distribution and accumulating regularity of these four secondary metabolites, the faceplates on flowering stage and leaves on budding stage have the most important medicinal value in H.annuus.

Key words: Helianthus annuus L., chlorogenic acid, polysaccharide, flavonoids, polyphenols
