木本森林蔬菜金雀花花蕾中类黄酮及主要营养成分分析

Flavonoids and Main Nutritional Components in Flower Buds of Caragana sinica,A Woody Forest Vegetable

为了探究木本森林蔬菜金雀花食用部位的营养价值,以新鲜金雀花花蕾为材料,对其花蕾中类黄酮和花青素进行靶向定量分析,并对粗蛋白、可溶性糖、脂肪、氨基酸、矿物元素等主要营养成分进行测定分析。结果显示:金雀花花蕾鲜样中总类黄酮含量为0.74 mg/g,含量最高的儿茶素达到95.58 ng/mg,总花青素的含量(16.06μg/g)远远低于总类黄酮的含量(0.74 mg/g),类黄酮为金雀花花蕾主要的活性化学物质;金雀花花蕾中粗蛋白含量23.65 g/100g、维生素C 40.00μg/100 mg、可溶性总糖86.80 mg/g、总膳食纤维23.40 g/100g;富含22种氨基酸,含有镁、磷、钾、钙等矿物元素,没有检测到有毒有害矿物元素。金雀花新鲜花蕾中主要营养成分安全、齐全,建议适宜地区推广种植。

In order to investigate the nutritional value of the edible parts of Caragana sinica,a woody forest vegetable,the flavonoids and anthocyanins in fresh C.sinica flower buds were targeted and quantitative analyzed,and the main nutritional components were determined.The results showed that the content of total flavonoids was 0.74 mg/g,and the highest content of catechins was 95.58 ng/mg.The content of anthocyanins(16.06μg/g)was much lower than that of flavonoids(0.74 mg/g).Flavonoid was the main active chemical substance in C.sinica flower buds.The main nutritional components were as follows:crude protein 23.65 g/100 g,vitamin C 40.00μg/100 mg,total soluble sugar 86.80 mg/g,total dietary fiber 23.40 g/100 g,22 kinds of amino acids,magnesium,phosphorus,potassium,calcium and other mineral elements.No toxic and harmful mineral elements were detected.The main nutritional components in fresh flower buds of C.sinica are safe and complete.It is suggested to popularize planting in suitable areas.
