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.
