摘要 楤木属(Aralia Linn.)植物作为食药兼用的野生植物,营养和医用价值极高。探究不同种楤木嫩芽中内含物含量的差异性和相关性,为选育推广营养价值较高的楤木提供参考。以棘茎楤木、圆叶楤木嫩芽为研究对象,测定其嫩芽的叶绿素、花青素、蛋白质、维生素C、皂苷、黄酮、多酚7种内含物含量,并进行差异性和相关性分析。研究发现棘茎楤木嫩芽中的花青素、皂苷和多酚含量显著高于圆叶楤木中的含量,棘茎楤木中的黄酮含量显著低于圆叶楤木嫩芽中的含量,棘茎楤木和圆叶楤木嫩芽中叶绿素、维生素C和蛋白质含量无显著差异。初步认为棘茎楤木的营养价值略高于圆叶楤木。 Aralia Linn.,as a wild plant with both food and medicine functions,has extremely high nutritional and medical values.The difference and correlation of inclusions in the buds of different Aralia species were explored,so as to provide reference for breeding and popularizing Aralia with higher nutritional value.The contents of chlorophyll,anthocyanin,protein,vitamin C,saponin,flavone and polyphenol in the buds of Aralia echinocaulis and Aralia caesia were determined,and the differences and correlations were analyzed.The results showed that the contents of anthocyanins,saponins and polyphenols in the buds of Aralia echinocaulis were significantly higher than those in Aralia caesia,and the contents of flavonoids were significantly lower than those in Aralia caesia.There were no significant differences in the contents of chlorophyll,vitamin C and protein between Aralia echinocaulis and Aralia caesia.Initially,It is considered that the nutritional value of Aralia echinacea is slightly higher than that of Aralia caesia.
