| 1. | The vegetables contain lutein and zeaxanthin
上述蔬果里面含有黄体素和玉米黄质。 |
| 2. | Lutein and zeaxanthin that help promote sharp and detailed eye vision
叶黄素和玉米黄质有助于促进敏锐的视觉。 |
| 3. | Lutein and zeaxanthin
叶黄素和玉米黄素 |
| 4. | Green leafy vegetables are the best plant source , but egg yolks are an even more concentrated source
绿叶蔬菜是叶黄素和玉米黄素最好的植物来源，蛋黄中的含量甚至更高。 |
| 5. | Contains beta - carotene , alpha - carotene , lutein and zeaxanthin , all of which help to relieve tired and dry eyes , at the same time strengthening and protecting the eye cells
含多种胡萝卜素、叶黄素及玉米黄质，保护及强化眼球细胞，改善眼睛疲倦、眼乾等情况。 |
| 6. | Lutein is an active carotenoid and potent natural source antioxidant . it is extracted from marigold flowers and contains a normal blend of carotenoids including : zeaxanthin and cryptoxanthin
叶黄素是一种活性类胡萝卜素，它是天然的抗氧化剂重要来源，取自万寿菊花，它含有一种纯混合类胡萝卜素：玉米黄质和隐黄质。 |
| 7. | Lutein , zeaxanthin and p - cryptoxanthin content in peel was about 2 . 5 - 15 times as their respective content in pulp on the basis of fresh weight hence the peel was the principal location for the carotenoid stock in citrus fruit . 2
与果肉相比，柑橘果皮单位鲜重叶黄质、玉米黄素、 -隐黄质的含量为果肉的2 . 5 15倍，是柑橘主要的类胡萝卜素库存部位。 |
| 8. | With development and maturation of citrus fruit , chlorophyll content of citrus fruit peel decreased , being acompanied by a gradual decrease in a - carotene and p - carotene which are known to be in the upstream of carotenoid biosynthesis pathway . the decrease continued up to complete vanishment of the carotenes . on the other hand , p - cryptoxanthin , p - citraurin and zeaxanthin that are in the downstream of carotenoid biosynthesis pathway increased steadily and became the principal carotenoid components
随着柑橘果实发育和成熟，果皮叶绿素含量下降，与此同时，位于类胡萝卜素生物合成途径上游的-胡萝卜素、 -胡萝卜素等胡萝卜素成分逐渐下降直至消失，而在类胡萝卜素生物合成途径下游的-隐黄质、 -柠乌素、玉米黄素等叶黄素成分逐渐上升，使得类胡萝卜素总量先略微下降后迅速上升；果实褪绿并呈现其特征色泽。 |
| 9. | L . in both peel and pulp of citrus fruit , the major carotenoids were lutein , zeaxanthin and p - cryptoxanthin . p - carotene content was lower than lutein , zeaxanthin and p - cryptoxanthin content and a - carotene was less than p - carotene . among the 53 varieties tested , lycopene was detected only in pulp of cara cara navel orange
柑橘果皮和果肉中均以叶黄质、玉米黄素、 -隐黄质为主， -胡萝卜素含量较低， -胡萝卜素极低；参试品种除红肉脐橙果肉含有番茄红素外，其余均未检测到。 |
| 10. | Xanthophyli cycle has been widely concerned since the finding that it has the function in heat dissipation . with the trans - thylakoid ph gradient , zeaxanthin ( z ) together with antheraxanthin ( a ) can absorb excess energy from chlorophyll and release it as heat , thus protect the photosynthetic apparatus from photodamage by high light . violaxathin de - epoxidase ( vde ) is the key enzyme in xanthophylls cycle
目前普遍认为叶黄素循环的色素定位于天线色素蛋白复合体上，在跨膜质子梯度( ph )形成后，玉米黄质( z )和环氧玉米黄质( a )能够从叶绿素中吸收过多的激发能，并以热能的形式耗散到体外，从而保护光合器官免受强光的破坏。 |
