| 摘 要： | 黄酮和皂苷不仅是植物中重要的防御性次生代谢产物,而且具有显著的药理和生理活性,对于植物的抗性研究和工业化应用具有重要意义。对鹰嘴紫云英(Astragalus cicer L.)、红豆草(Onobrychis viciaefolia Scop)、百脉根(Lotus corniculatus L.)、小冠花(Coronilla varia L.)、黄花草木樨(Melilotus officinalis(L.)Desr.)和苜蓿(Medicago L.)多种豆科牧草中总黄酮和总皂苷的周年积累规律和分布特点进行研究,以期为豆科牧草建立科学的牧刈制度和合理应用提供理论依据。结果表明:总黄酮和总皂苷在不同属间和品种间的动态变化各不相同;在不同组织中的分布也不同,在整个生育时期,均为叶片中的含量多于茎秆中的。前5种豆科牧草的总黄酮含量显著高于苜蓿,是提取总黄酮的优质材料;红豆草、鹰嘴紫云英、黄花草木樨及苜蓿的总皂苷含量均高于小冠花和百脉根,是提取皂苷产品的优质材料。

| Abstract: | Flavonoids and saponins not only are typical secondary metabolites,but also display obviously biological and pharmacological activities which are important to plant resistance research and industrial application.Annual accumulation patterns and distribution characteristics of total flavonoids and saponins in Astragalus cicer L.,Onobrychis viciaefolia Scop,Lotus corniculatus L.,Coronilla varia L.,Melilotus officinalis(L.) Desr.and Medicago L.were investigated in order to provide theoretical foundation for scientific grazing and mowing systems and reasonable application of legumes.Results showed that total flavonoid and saponin contents vary from genus to genus,from cultivar to cultivar,and also from tissue to tissue.Both total flavonoid and total saponin contents in leaf tissue were greater than that in stem tissue during whole growth period of all tested legume grass.The total flavonoids contents of Astragalus cicer L.,Coronilla varia L.,Lotus corniculatus L.,Onobrychis viciaefolia Scop and Melilotus officinalis(L.) Desr.were more than Medicago L..While the total saponins contents of Coronilla varia L.and Lotus corniculatus L.were less than that of Astragalus cicer L.,Onobrychis viciaefolia Scop,Melilotus officinalis(L.) Desr.and Medicago L.. |
