摘要:
采用高效液相色谱二极管阵列检测法(HPLC-DAD)快速测定桑树(Morus alba L.)上桑叶和桑枝条皮层(以下简称桑枝皮)中的4种色素(叶黄素、β-胡萝卜素、叶绿素a和叶绿素b)含量,分析各种色素含量在不同叶位和不同桑树品种间存在的差异。结果表明,不同叶位桑叶中的类胡萝卜素含量高于叶绿素含量,但不同叶位桑叶中的上述色素含量具有差异,总体上是成熟叶或老叶中的含量较高,其中β-胡萝卜素、叶绿素b在第7位成熟叶中的含量最高,分别为254.06、117.66 μg/g;叶绿素a在第11位成熟叶中的含量最高,为78.77 μg/g;叶黄素在第5位衰老叶中的含量最高,为250.66 μg/g。不同桑树品种桑叶和桑枝皮中的色素总含量有差异,在10个供试品种中对于桑叶而言含量最高的是湖桑32(1 128.32 μg/g);对于桑枝皮而言,沙二含量最高(190.21 μg/g)。桑枝皮中色素平均总含量在100 μg/g左右,约为桑叶的1/8。所以,从废弃的桑枝条皮层中或从桑枝皮加工废料中提取或回收脂溶性的叶绿素和类胡萝卜素特别是叶黄素是切实可行的。测定方法和试验结果可为今后更好地开发和利用桑树资源特别是桑树枝条皮层中的色素提供重要的试验数据。
