  • Lycopene是番茄,番茄产品和其他红色水果和蔬菜中天然存在的类胡萝卜素; 具有抗氧化作用。
  • 番茄红素(Lycopene)是一种很强的抗氧化剂,具有极强的清除自由基的能力,对防治前列腺癌、肺癌、乳腺癌、子宫癌等有显著效果,有效抑制癌细胞的扩散和复制,还有预防心脑血管疾病、提高免疫力、保护细胞DNA免受自由基损害,防止细胞病变、突变、癌变;含强力抗氧化生物活物质,能促使细胞的生长和再生,美容袪皱,维持皮肤健康,延缓衰老等功效,有“植物黄金”之称,被誉为“21世纪保健品的新宠”。它是自然界中最强的抗氧化剂,其抗氧化作用是β-胡萝卜素的2倍,VE的100倍。在清除人体“万病之源”――自由基方面,番茄红素的作用比β-胡萝卜素更强大。2003年,美国《时代》杂志把番茄红素列在“对人类健康贡献最大的食品”之首,番茄红素也因此被称为“植物中的黄金”,番茄红素已在欧美、日本和中国港台地区被广泛接受。对防治前列腺疾病、前列腺癌、肺癌、胃癌、乳癌有奇效,有效抑制癌细胞的扩散和复制,被西方国家称为“植物黄金”。
    一、预防和抑制癌症:最新研究成果表明,每天摄取30毫克番茄红素,可以达到预防前列腺癌、消化道癌以及膀胱癌等多种癌症的效果。人体无法合成番茄红素,必须从膳食中摄取,吃一个生番茄只能吸收0.05毫克的番茄红素。因此,在前列腺疾病的治疗中,补充番茄红素是必不可少的。
    二、保护心血管:在动脉粥样硬化的发生和发展过程中,血管内膜中的脂蛋白氧化是一个关键因素。番茄红素在降低脂蛋白氧化方面发挥着重要作用。据报道,口服天然番茄红素,能使血清胆固醇降至5.20毫摩尔/升以下,番茄红素用于防治高胆固醇和高血脂症,可以减缓心血管疾病的发展。
    三、抗紫外线辐射功能:番茄红素能对抗紫外线损伤。研究人员给10名健康人各补充28毫克β-胡萝卜素和2毫克番茄红素1-2个月,结果服用番茄红素人群紫外线引发红斑的面积减少,程度减轻。
    四、抑制诱变作用:肿瘤生成的重要机制之一是组织细胞在外界诱变剂的作用下发生基因突变,而番茄红素能阻断这个过程,发挥抗癌作用。如地中海地区居民在煎烤鱼和肉的同时使用番茄酱,减少了烹调过程中杂胺等诱变剂的形成。所以虽然当地居民喜食易致癌的煎烤食物,但是宫颈癌、前列腺癌以及肝癌的发病率却很低。延缓衰老。
    五、增强免疫力:番茄红素可以最有效地清除人体内的自由基,保持细胞正常代谢,预防衰老。番茄红素在体内通过消化道粘膜吸收进入血液和淋巴,分布到睾丸、肾上腺、前列腺、胰腺、乳房、卵巢、肝、肺、结肠、皮肤以及各种粘膜组织,促进腺体分泌激素,从而使人体保持旺盛的精力;清除这些器官和组织中的自由基,保护它们免受伤害,增强机体免疫力。印度学者指出,番茄红素可令不育男子精子数量增加、活力增强,从而医治不育问题。番茄红素可大大改善皮肤过敏症,消除因皮肤过敏而引起的皮肤干燥和瘙痒感,令人感觉轻松愉快。番茄红素大量存在于体内各种黏膜组织,长期服用可以改善各种因体内黏膜组织破坏而引发的各种不适。如干咳、眼睛干涩,口腔溃疡,保护胃肠道黏膜组织等。
    六、番茄红素还具有极强的解酒作用。酒精在人体内的代谢过程主要是氧化还原反应,会产生大量的自由基。平时服用番茄红素,可以增加酒量;喝酒前服用,解酒效果显著,可以减轻酒精对肝脏的损伤;而醉酒后服用,可以减轻头痛、呕吐等醉酒症状。
    七、番茄红素还具有预防骨质疏松、降血压、减轻运动引起的哮喘等多种生理功能。番茄红素没有任何副作用,非常适合长期保健服用。
    八、番茄红素可帮助预防及改善前列腺增生、前列腺炎等泌尿系统疾病,并有助于提高男性精子质量,降低不育风险。一项来自美国哈佛大学的研究发现类胡萝卜素与前列腺癌有一定的关系。在类胡萝卜素的研究中,只有番茄红素具有明确的保护作用。男性每天在饮食中服用最大剂量的番茄红素(每天6.5毫克以上)与服用最少者相比,可以使前列腺癌发生的危险减少21%。番茄红素大量存在与番茄中,番茄红素可消除令男性不育的有害化学物。因此多喝番茄汤可以有效增强男性的生育能力。英国科学家发现,令番茄汤呈现红色的茄红素,或许能把男性体内的精子强化成超级精子,科学家由此推断男士只要每日饮一碗番茄汤,将能大大增强生育能力。英国朴茨茅斯大学生化科学部的5名泌尿科专家随机挑选了平均年龄在42岁左右的精壮男士,要求他们在两周内每天饮用一碗番茄汤,其间收集他们的精液样本。结果发现,精液内可消除令男性不育的有害化学物自由基的茄红素水平显著增加,升幅介乎7%到12%。

体外研究 由于人类无法从头合成番茄红素,因此必须从饮食中充分摄取番茄红素以从其健康促进效果中受益。番茄红素在1.25μM的生理相关浓度下显着抑制前列腺癌和乳腺癌细胞生长,并且还导致细胞中κB磷酸化抑制剂减少30-40%[1]。西红柿中一种主要类胡萝卜素的番茄红素的摄入量增加,作为全反式异构体消耗减少酒精诱导的2E1细胞凋亡并降低前列腺癌,肺癌和消化道癌症的风险。番茄红素通过作为单线态分子氧和过氧自由基清除剂起到防光氧化过程的作用,并且可以与其他抗氧化剂协同作用[2]。作为类胡萝卜素的番茄红素可以以三种不同的机制与活性氧物质(ROS)的类型反应:I)通过电子转移,II)通过氢原子转移或III)通过加合物形成。番茄红素能够主要通过物理猝灭使单线态氧失活[3]。番茄红素通过抑制PKC途径引起的NADPH氧化酶降低SK-Hep-1细胞中的ROS产生[5]。
体内研究 番茄红素是人血浆中最主要的类胡萝卜素,半衰期约为2-3天[2]。番茄红素或加工番茄可能导致血管壁内膜中层厚度减少[3]。番茄红素对大鼠肾上腺皮质中ATZ诱导的毒性具有保护作用。这些影响可能归因于番茄红素的抗氧化特性及其激活Nrf2/HO-1途径的能力[4]。番茄红素可改善肝毒性,起抗氧化剂作用,降低GSSG,调节tGSH和CAT水平,减少氧化损伤[5]。
细胞实验 用(0,0.5,1.25,2.5和5μM)番茄红素处理PC3细胞和MDA-MB-231细胞48小时。使用比色MTS测定方法测量细胞存活/生长。向每个孔中加入MTS-PMS复合物(20μL)。活细胞的催化活性导致甲dye染料产生,然后量化。将细胞与染料一起孵育1小时,然后在分光光度计上读取492nm处的吸光度[1]。
动物实验 大鼠:番茄红素溶解在玉米油中。将35只成年雄性白化病大鼠随机分成5组:未处理对照组,媒介物对照组(每天接受0.5毫升玉米油),番茄红素(10毫克/千克体重/天),ATZ(溶于0.5毫升玉米油300毫克/千克) bw /天)和ATZ +番茄红素。所有治疗均通过口服强饲法治疗4周[4]。

可采用三孢布拉氏霉的两性菌株发酵生产β胡萝卜素。将三孢布拉氏霉的“+”和“-”菌株分别在液体培养基中26℃培养48h,将各培养液分别添加于发酵培养基中,用量各为10%左右,发酵两天后,加入β紫罗兰酮,于发酵温度26~28℃,pH=57~70条件下再发酵3~6天。然后将培养物用湿热杀死(100℃中10~15min),以阻止胡萝卜素的再发酵分解。发酵培养基中含有油脂,在发酵过程中产生的胡萝卜素溶解在油中,故发酵结束后将菌体过滤掉,胡萝卜素即存在于滤液中。滤液在50~55℃真空干燥,然后用石油醚萃取,再上柱层析,浓缩收集液后即得β胡萝卜素。
