柑桔类水果所含有的人体保健物质,目前已分离出30余种,其中主要有:类黄酮、单萜、香豆素、类胡萝卜素、类丙醇、吖啶酮、甘油糖脂质等

类黄酮:柑橘类水果所含的类黄酮有三种类型:Ⅰ型是以芦丁为代表的一般性黄酮类;Ⅱ型是橘皮苷、柚皮苷之类柑橘类水果特有的黄烷酮;Ⅲ型是其他蔬菜水果中至今尚未发现而只有柑橘类才具有的柑橘黄酮等含有聚甲氧基的特殊黄酮类物质。

类胡萝卜:众所周知,许多蔬菜、水果中含有类胡萝卜素,这是对人体健康具有重要作用的万分。对类胡萝卜素的生理功能及其机理的研究近年发展很快,我国也已利用这类物质研制成一些保健食品并实现了工业化生产。

香豆素:柑橘中所含有的香豆素是目前已被科学家充分肯定的抗癌物质。研究结果表明,香豆素的抗癌功能形成途径主要有二:一是香豆素通过解毒酶的作用使癌物质解毒;二是与癌物质拮抗抑制其代谢的活性化。这两方面的作用主要在癌的起始阶段产生抑制效果。

单萜、三萜 柑橘中含有大量以(R)—柠檬烯为代表的萜类化合物。萜是构成柑橘独特芳香的物质,具有使人的中枢神经镇静化的作用,近年的研究还确认它具有减轻应激的效果,能使人消除疲劳。

柠檬苦素:柠檬苦素是柑橘果汁饮料的苦味成分,柑橘果实中的含量约为100-200ppm。但是,近年研究发现,柠檬苦素也具有抑制肿瘤的功能。

橘子的介绍

橘子为芸香科植物福橘或朱橘等多种橘类的成熟果实。橘子常与柑子一起被统称为柑橘,颜色鲜艳,酸甜可口,是日常生活中最常见的水果之一。

橘子的营养

1. 橘子富含维生素C与柠檬酸,前者具有美容作用,后者则具有消除疲劳的作用;
2. 橘子内侧薄皮含有膳食纤维及果胶,可以促进通便,并且可以降低胆固醇;
3. 橘皮苷可以加强毛细血管的韧性,降血压,扩张心脏的冠状动脉,故橘子是预防冠心病和动脉硬化的食品,研究证实,食用柑橘可以降低沉积在动脉血管中的胆固醇,有助于使动脉粥样硬化发生逆转;
4. 在鲜柑橘汁中,有一种抗癌活性很强的物质“诺米灵”,它能使致癌化学物质分解,抑制和阻断癌细胞的生长,能使人体内除毒酶的活性成倍提高,阻止致癌物对细胞核的损伤,保护基因的完好。
