摘要
为甘草优良品种选育提供材料和理论依据,采用HPLC法、紫外分光光度法,对不同甘草植株根及地上部分药用成分甘草酸、甘草黄酮、甘草多糖含量进行比较分析。结果表明,不同甘草植株根及地上部分3种药用成分含量差异显著。根中甘草酸含量最高为最低的13倍以上,甘草黄酮含量最高为最低的1.6倍以上,甘草多糖含量最高为最低的2.5倍以上。认为甘草酸、甘草黄酮、甘草多糖含量均较高的3个植株可作为优良类型培育优质的甘草栽培品种;甘草酸、甘草黄酮、甘草多糖含量的高低与甘草植株高矮和茎表皮颜色没有必然联系。
The contents of glycyrrhizic acid,flavoniods and glycyrrhiza polysaccharide in root and aerial parts of different Glycyrrhiza uralensis samples were compared to provide excellent cultivars and theoretical basis for the breeding of fine varieties of licorice.HPLC and UV spectrophotometry were used to determine the contents of glycyrrhizic acid,flavoniods and glycyrrhiza polysaccharide to analyze different samples.There were significant differences among different samples on the contents of glycyrrhizic acid,flavoniods and glycyrrhiza polysaccharide both in root and aerial parts.Glycyrrhizic acid content of roots up to 13 times higher than the lowest,the highest content of flavonoids was 1.6 times higher than thelowest,the highest content of glycyrrhiza polysaccharide was more than 2.5 times the lowest.The 3 plants which had much more glycyrrhizic acid,flavoniods and glycyrrhiza polysaccharide could be used to nurture cultivars with higher chemical constituents.There was no correlativity between apparent characters such as height of plant and color of stem and the contents of glycyrrhizic acid,flavoniods and glycyrrhiza polysaccharide.
