In order to elucidate the physiological mechanism of carotenoid formation in citrus fruit , we determined a - carotene , p - carotene , lycopene , p - cryptoxanthin , zeaxanthin and lutein content in 53 varieties that belong to various citrus types using hplc , analyzed the possible connection between color formation and carotenoid accumulation , and studied the effects of light . ga3 and mpta on carotenoid biosynthesis in peel of citrus fruit . the results are summarized below 為探討柑橘果實類胡蘿卜素形成的生理機制,本論文運用hplc技術測定了我國寬皮柑桔類、橙類、柚類及雜柑類等不同柑橘類型共53個品種(系)的-胡蘿卜素、 -胡蘿卜素、番茄紅素、 -隱黃質、玉米黃素、葉黃質六種類胡蘿卜素的含量,分析了柑橘果實不同色澤的呈現與果皮類胡蘿卜素積累的可能聯系,并探討了光照、 ga _ 3 、 mpta等不同處理對柑橘果皮類胡蘿卜素形成的調控機制,主要結果如下: 1

Their clients include several major food and pharmaceutical companies which have asked for vehicles for nutraceuticals such as lycopene ( which can lower the risk of contracting prostrate or breast cancer ) , phytosterol ( which helps prevent the accumulation of cholesterol ) , and lutein ( which retards cataract growth ) 他們的客戶包括一些大型食品及制藥公司,要求制作的“納米車“包括能降低患收縮無力前列腺癌和乳腺癌的可能性的番茄紅素,有助于防止膽固醇積累的植物甾醇,以及能阻止白內障形成的葉黃素。

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葉黃質、玉米黃素、 -隱黃質為主, -胡蘿卜素含量較低, -胡蘿卜素極低;參試品種除紅肉臍橙果肉含有番茄紅素外,其余均未檢測到。

And they used themselves as guinea pigs . after taking a lutein supplement for 140 days , they found that the macular pigment levels in their own eyes increased from 20 to 40 percent , which would reduce the amount of blue light reaching the macula by 30 to 40 percent 研究人員以自己來做實驗,結果發現在口服了140天黃體素補充劑之后,他們眼睛里的黃斑色素含量提高了20 %到40 %不等,且藍光到達黃斑的量減少了30 %到40 % 。

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 與果肉相比,柑橘果皮單位鮮重葉黃質、玉米黃素、 -隱黃質的含量為果肉的2 . 5 15倍,是柑橘主要的類胡蘿卜素庫存部位。

The company strictly adheres to every quality indicator of the ssop system . it supplies a series of high quality products , such as chilli red pigment , lutein , capsanthin , chilli extract , chilli oil , garlic powder and garlic oil 公司嚴格遵循ssop衛生質量指標,向客戶提供辣椒紅色素、辣紅素、辣椒精、辣椒油以及蒜粉、大蒜精油等一系列優質產品。

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 葉黃素是一種活性類胡蘿卜素,它是天然的抗氧化劑重要來源,取自萬壽菊花,它含有一種純混合類胡蘿卜素:玉米黃質和隱黃質。

Since all subjects were receiving multivitamin throughout the trial , preservation of visual function may in part be attributed to multivitamin , or its combination with lutein 由于在整個實驗過程當中,所有受試者都服用了復合維生素,保存視功能可能也跟復合維生素有關,或者復合了葉黃素。

Macular degeneration : a carotenoid called lutein - which is found mostly in leafy greens - may help prevent the deterioration of the retina that causes blindness in older people 黃斑退化癥多數葉菜類中均可發現的類胡蘿卜素黃體素,可以幫助預防視網膜退化,這種疾病經常造成老人失明。

Provides significant levels of phytonutrients : 1 - 10 mg lutein , 1 - 10 mg lycopene , and 50 - 250 mg flavonoids from multiple sources 提供顯著劑量的植物性營養: 1 - 10毫克的葉黃素、 1 - 10毫克的蕃茄紅素以及從多種來源中取得50 - 250毫克的類黃酮。

In order to detect the lutein content in plants by hplc , different pre - treatment methods were used to compare the effect of the extraction 摘要采用高效液相色譜分析方法分析測定植物樣品中的葉黃素含量,對不同的前處理方法進行了實驗。

In fruit of most citrus reticulata varities , p - cryptoxanthin was the main carotenoid component in pulp and its content approximated lutein content in peel 在寬皮柑橘中,果肉以積累-隱黃質為主,果皮-隱黃質與葉黃質含量接近。

Lifepak includes significant amounts of antioxidants such as the carotenoids , lutein , lycopene and a number of potent bioflavonoids 如沛內含顯著數量的抗氧化物,包括類胡蘿卜素、葉黃素、蕃茄紅素以及若干的生物類黃酮。

Subjects received multivitamin supplementation in addition to their lutein or placebo throughout the trial 整個實驗,受試者都補充復合維生素,不管是葉黃素還是安慰劑。

Long ? term lutein and multivitamin effects on vision in rp patients need to be further investigated 長期的葉黃素和復合維生素對rp患者的視力作用需要進一步研究。

No adverse effects were observed for lutein , while one patient could not tolerate multivitamin 沒有發現葉黃素有不良作用,其中有一名患者不能忍受復合維生素。
