Abstract:

Abelmoschus moschatus Medicus was used as the research object to analyze its nutrition and active ingredients， which was expect to provide a theoretical basis for its deep processing and development of functional food resources. Nutritional contents and active contents from Abelmoschus moschatus Medicus were determined by national standard and colorimetric method. The results showed that okra was rich in total sugar （8 478.12 mg·100 g^-1 FW）， crude fibre （2 433.57 mg·100 g^-1 FW）， protein （386.32 mg·100 g^-1 FW） and essential amino acids. The crude fat content in okra was lower （110.84 mg·100 g^-1 FW） than that in other vegetables， and the crude fat was mainly composed of unsaturated fatty acids such as linoleic acid and so on， which accounted for about 48.95 % of the total fatty acids content. Okra was also particularly rich in potassium （1 309.21 mg·100 g^-1 DW）， which was a high K/Na ratio vegetable. Polysaccharide， polyphenols and flavonoids were main active substances in okra， their contents were 2 362.52， 65.64 and 12.01 mg·100 g^-1 FW. It can be seen that okra is a kind of green and healthy vegetable with rich nutrition， deserving further investigation on its application value.

摘要：

对黄秋葵的营养成分和活性成分进行了系统分析，以期为其精深加工及功能食品资源研究与开发提供理论依据。采用国标法和比色法分别对黄秋葵的营养成分和活性成分进行分析。结果表明，黄秋葵中总糖含量丰富,为8 478.12 mg·100 g^-1 FW，富含粗纤维(2 433.57 mg·100 g^-1 FW)、蛋白(386.32 mg·100 g^-1 FW)及人体必需氨基酸；粗脂肪含量低(110.84 mg·100 g^-1 FW)，脂肪酸组成以亚油酸等不饱和脂肪酸为主，占总脂肪酸的48.95%；钾元素含量高，为1 309.21 mg·100 g^-1 DW，是一种高钾/钠比蔬菜。此外，多糖、总酚和总黄酮作为主要活性物质，含量分别达到2 362.52、65.64和12.01 mg·100 g^-1 FW。结果表明，黄秋葵营养成分和活性成分丰富，是一种绿色健康的保健蔬菜，值得深入研究其应用价值。
