黄秋葵不同组织总黄酮与粗多糖含量的比较

Flavonoids and Polysaccharide Content in Different Organization of Abelmoschus Esculentus

目的:研究黄秋葵不同组织中总黄酮和粗多糖的含量,为其综合利用提供理论依据。方法:采用紫外分光光度计法测量黄秋葵嫩叶、种子、老叶、茎杆、果荚和嫩果中总黄酮和粗多糖的含量。结果:黄秋葵不同部位中总黄酮的含量以嫩果为最多,为2.12%,嫩叶、种子、老叶、茎杆和果荚含量较低。粗多糖也以嫩果含量最高,为5.59%,其次为果荚、老叶、茎杆、嫩叶,种子含量最低。对于不同长度的黄秋葵嫩果,其长度越短总黄酮含量越高;而粗多糖含量随着黄秋葵嫩果长度的增加呈先降低后增多的趋势。结论:黄秋葵各部位总黄酮和粗多糖的含量以嫩果最高,总黄酮以Ⅰ类嫩果含量最高,为2.53%,粗多糖以Ⅳ类嫩果含量最高,为5.59%。

Purpose：Study the flavonoids and polysaccharide content in the different parts of okra,to provide theoretical basis for its com-prehensive utilization.Methods：Used UV spectrophotometer to determination flavonoids and polysaccharide content in tender leaves, seeds, old leaves, stem, fruit pods and fruitlet of okra.Results：The most content of flavonoids in different parts of okra is fruitlet, to 2.12%, the content in tender leaf, seed, old leaves, stem and pod is low.The most polysaccharide content is fruitlet too, is as high as 5.59%, followed by pod, old leaves, stem, leaf, seed content is the lowest.For different lengths of okra fruitlet, the flavonoids content is higher when the fruitlet is shorter;the polysaccharide content increased after the first reduce trend with the increase of okra soft fruit length.Conclusions：The flavonoids and polysaccharide content in fruitlet is highest.Flavonoids content inⅠlevel fruitlet is highest, at 2.53%;polysaccharide content inⅣlevel fruitlet is highest, at 5.59%.
