摘要:

以野生贯筋藤花为材料,采用相关国家标准规定方法,研究其常规、微量营养成分以及重金属。结果表明,野生贯筋藤花中水分含量为90.67%,蛋白质含量为2.55%,脂肪含量为3.33%,灰分含量为2.07%;野生贯筋藤花富含维生素和矿物质,每100 g中有硫胺素0.134 mg、核黄素0.050 5 mg、VC 63.3 mg;钙、磷、钾、铁、锌、铜含量分别为768、594、5 240、13.7、2.98、1.64 mg/kg。此外,野生贯筋藤花还含有丰富的赖氨酸等必需氨基酸和黄酮类成分,且重金属污染小,绿色无污染。野生贯筋藤花营养丰富、食用价值高、开发潜力较大。

Abstract:

This study aimed to analyze the nutritional composition of the edible flowers from Dregea sinensis Hemsl. The
fresh flowers of Dregea sinensis Hemsl were determined for macro- and micro-nutrients, and harmful heavy metal elements.
The results showed that the flowers contained 90.67% water, 2.55% protein, 3.33% fat, 2.07% ash, 0.134 mg/100 g thiamine,
0.050 5 mg/100 g riboflavin, 63.3 mg/100 g ascorbic acid, 768 mg/kg calcium, 594 mg/kg phosphorus, 5 240 mg/kg
potassium, 13.7 mg/kg iron, 2.98 mg/kg zinc, and 1.64 mg/kg cuprum. In addition, the edible flowers were also rich in
vitamins and minerals and contained 0.134, 0.050 5 and 63.3 mg/100 g of thiamine, riboflavin and VC, and 768, 594, 5 240,
13.7, 2.98 and 1.64 mg/kg of calcium, phosphorus, potassium, iron, zinc and copper, respectively. Essential amino acids
such as lysine, and flavonoids were abundant in the flowers of Dregea sinensis Hemsl, which were free from heavy metal
pollution. Thus, the flowers of Dregea sinensis Hemsl have high nutritional value and a great development potential.
