Lycopene is important for men , especially for prostate health . vitamin a and zinc help protect the reproductive organs and together with lycopene can provide a big boost to prostate health 番茄红素对男士健康尤其重要，有效促进前列腺健康，预防前列腺细胞病变；而维他命a和锌也能保护性器官细胞，两者一起补充，男士无后顾之忧。
Loaded with the antioxidant lycopene , tomatoes and cooked tomato products pack a big health punch ( at 32 milligrams , 1 cup of spaghetti sauce serves up the day ' s recommended intake ) 番茄内含有抗氧化作用的番茄红素，生番茄和熟番茄可以在健康方面带给人很大作用(一天建议摄入量为32毫克，一杯意大利面酱就可以达到这个建议摄入量的水平) 。
Researchersat warsaw agriculture university found organic tomatoes contained morevitamin c , beta - carotene and flavonoids than conventional ones . theywere lower , however , in lycopene , which is another beneficial nutrient 华沙农业大学研究人员发现，与传统西红柿相比，有机西红柿含有较多的维生素c 、 b -胡萝卜和黄酮，但另一种有益的营养成分番茄红素含量却较低。
American association for cancer research shows that daily doses of lycopene , and antioxidant that ripens tomatoes and gives them their red color , may not only prevent prostate cancer but shrink existing tumors as well 美国肿瘤研究协会的一份研究报告表明，每天服用一定剂量的番茄红素和能使西红柿成熟变红的抗氧化剂，不仅能预防前列腺癌，而且能使已存在肿瘤缩小。
Northern blot analysis showed higher expression level of pds gene in the stigma and anther than in the leaf and stem . the information we have got is very important for the further research of gene structure , expression and function of phytoene desaturase 此基因的克隆，为深入研究八氢番茄红素脱氢酶基因结构、表达和调节机制及其结构和功能的关系奠定了重要的基础。
Sequence analysis showed highly similarity to other plants such as narcissus pseudonarcissus . , and they all possess a short highly conserved n - terminal sequence encoding a dinucleotide cofactor binding site . thus it is a new member of phytoene desaturase gene family 由此可认为该番红花八氢番茄红素脱氢酶基因在结构上与其它植物八氢番茄红素脱氢酶基因是同源的，是八氢番茄红素脱氢酶基因家族中的一个新成员。
Phytoene desaturase ( pds ) has recently been identified as an important enzyme in carotenoid metabolitic pathway . a new full - length cdna clone encoding phytoene desaturase gene was isolated from stigma of saffron using rt - pcr and race techniques ( ( genbank accession no . ay 183118 ) ) 其中主要的活性成分是西红花甙，需经类胡萝卜素代谢途径合成，而八氢番茄红素脱氢酶( phytoenedesaturase )是此途径中的一个早期关键酶。
For prokaryotic expression , the coding region of the cdna of the phytoene desaturase gene was cloned by pcr and inserted into a prokaryotic expression vector pet - 21a ( + ) . the gene was overexpressed in e . coli bl21 ( de3 ) and gave rise to a 63 kd mature protein in response to the iptg induction 用pcr方法扩增番红花八氢番茄红素脱氢酶( pds )编码区序列，定向克隆到表达载体pet一艺1a ( + )上，获得重组质粒pet一21a ( + ) / cspds 。
In the may issue of cancer epidemiology , biomarkers & prevention , researchers based at the national cancer institute and fred hutchinson cancer research center report that lycopene , an antioxidant predominately found in tomatoes , does not effectively prevent prostate cancer 来自美国国家癌症研究所和佛瑞德?哈金森癌症研究中心的研究人员在《癌症流行病学、生物标记物和预防》 5月刊发表的报告指出，西红柿中的主要抗氧化成分? ?番茄红素，不能有效地预防前列腺癌。
The results showed as follows : lycopene could not be detected in every variety during growing , showed that lycopene is transformed into a - carotene and 0 - carotene immediately in course of the biosynthesis of carotenoids , so lycopene can not be accumulated in carrots 试验结果表明：在各品种胡萝卜的整个肉质根膨大期间均检测不到番茄红素，说明胡萝卜在合成胡萝卜素过程中，所合成的番茄红素都及时被lyc转化成了-胡萝卜素和-胡萝卜素，因此在胡萝卜中无法得到积累。
