| 摘 要： | 目的]以花楸树为研究对象,探究不同部位物质成分组成和含量差异以及不同生境条件对物质含量的影响。方法]采用有机溶剂浸提及液相色谱法测定了花楸树不同部位(嫩枝、嫩叶、成熟叶、鲜果和干果)营养和药用物质。结果]结果表明:花楸树不同部位含有丰富的营养和药用物质,其中成熟叶片中维生素C、类胡萝卜素和黄酮类物质含量较高,干果中蛋白质、可溶性糖、总酚、花色苷和单宁含量较高;与北京花楸相比,花楸树不同部位蛋白质、花色苷、黄酮类物质和总酚含量均较高,其中果实中花色苷和类胡萝卜素含量分别约为北京花楸的3倍和5倍,成熟叶片中的黄酮类物质和总酚含量约为2倍;花楸树新鲜果实中黄酮类和酚类物质种类丰富,其中槲皮素和表儿茶素的含量最高,且分别约为北京花楸的1.5倍和3倍。结论]与北京花楸相比,花楸树的营养物质和药用成分的含量更高,值得加强其果实和叶片中黄酮和果实酚类物质资源的开发利用。

| Abstract: | Objective] Taking Sorbus pohuashanensis as object to study the discrepancy among different parts of S.pohuashanensis and the impact of different habitat conditions on the content of the substances. Method] The nutritive and medicinal substances of different parts of S. pohuashanensis(twigs, young leaves, mature leaves, fresh fruits and dried fruits) were extracted by organic solvent and the compositions were determined by liquid chromatography.Result] Different parts of S. pohuashanensis are rich in nutritive and medicinal substances. The contents of vitamin C, carotenoids, flavonoids in mature leaves and protein, soluble sugar, total phenols, anthocyanin, tannin in dried fruits are higher than that in other parts. Compared with S. discolor, the contents of protein, anthocyanin, flavonoids and total phenols in S. pohuashanensis are higher. The contents of anthocyanin and carotenoids in fruits of S. pohuashanensis are about 3 times and 5 times of that in S. discolor respectively. The contents of flavonoids and total phenols in mature leaves of S. pohuashanensis are about 2 times of that in S. discolor. The fresh fruit of S. pohuashanensis is rich in flavonoids and phenolic compositions, of which the contents of quercetin and epicatechin are the highest, and about 1.5 times and 3 times of that in S. discolor respectively. The contents of various substances in fresh fruits of S. pohuashanensis are different in different habitats. Conclusion] S. pohuashanensis is of higher nutritive and medicinal components than S. discolor, and the flavonoid and phenols contents in leaves and fruits is worth to be further exploited and utilized. |
