Analysis and comparison of nutrients and active substances in five kinds of okra

Through measuring nutrients and active substances of five kinds of okra to compare the differences between different varieties.The results showed that the ash, crude fat, crude protein, total sugar, polysaccharide, total flavonoids content in five kinds of okra tender pod were 4.33~6.53, 1.54~2.05, 1.96~2.46, 64.35~68.64, 2.60~2.87, 1.66~1.97 g·100 g-1, the coefficient of variation were 14.36%, 9.62%, 10.22%, 2.38%, 3.95%, 7.36%. The ash, crude fat, crude protein, total sugar, polysaccharide, total flavonoids content in five kinds of okra tender seed were 4.50 ~5.95, 15.05 ~ 17.37, 22.73 ~ 25.36, 20.48 ~25.03, 1.20~1.59, 2.03~2.20 g·100 g-1, the coefficient of variation were 11.67%, 4.91%, 4.21%, 8.19%, 9.47%, 2.89%.The nutritional components of five kinds of okra tender pods mainly contained total sugar, followed by ash, crude protein, crude fat content was the lowest.Five kinds of okra tender seed mainly contained crude fat, crude protein, polysaccharide, the proportion of the three was balanced.The polysaccharide content of five okra tender pods were higher than that of tender seeds, the content of total flavonoids was lower than that of tender seeds ( p < 0.05) .The polysaccharide and total flavonoids content of okra tender pods and seeds were higher than the old pods and seeds ( p < 0.05) .
