The results show that the ratios of chlorophyll to carotenoid, purpurin and red pigment for four maize genotypes decrease under low P dose. Those of "7922" and "Ye107" are 0.4~0.8 times those under high P dose, with much higher decrease than in "178" and "(superscript *)082".

结果表明，低磷条件下，玉米叶片叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素均减少，其中基因型"7922"和"掖107"的叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素减少幅度较大，为高磷条件下的0.4~0.8倍，且减少幅度高于"178"和"082"。

In order to study the protection of β-carotene and vitamin C against the transformation of human lung fibroblasts cell induced by nickel sesquioxide, HLF cells were treated repeatedly by different concentrations of Ni2O3 in vitro.β-carotene (5.4mg/L) and vitamin C(1.8mg/L) were added into the media containing Ni2O3 (1.0mg/L) respectively. The identification of malignancy of the transformation of HLF cell was carried out by the tests of ConA and the growth on semisolid agar culture. The results showed that Ni2O3 could induce the malignant transformation of HLF cell. The transformed cell proliferated rapidly.

为了探讨三氧化二镍(Ni2O3)诱导人肺成纤维细胞恶性转化作用以及β-胡萝卜素和维生素C的保护作用，用不同浓度的Ni2O3在体外多次处理HLF细胞，利用刀豆凝集素A凝集实验和软琼脂集落形成实验进行转化细胞的恶性鉴定；同时添加β-胡萝卜素(5.4mg/L)和维生素C的食物(1.8mg/L)，观察对Ni2O3转化作用的影响。

Carotene is one of the prevalent carotenoids in diets and also a scavenger of singlet oxygen.

而-胡萝卜素是饮食中，含量较高的一种类胡萝卜素，具有清除单态氧，及延缓脂质过氧化的抗氧化能力。

The results showed that sweet pepper from Guangdong province is the best candidate for extraction and the best extracting conditions are as follows: alcohol solution (95%) as menstruum, the ratio of powder and menstruum at 1:16g/ml and at the temperature of 50 ℃ for 3 h. The condensed umber oily product has high ASTA value (≥1000) and Hg element lower than 0.01 mg/kg.

辣椒红素是有一定辣味的粘性油状液体，在浓绸时为深红色，在浓度较低时为橙黄色到黄色，构成辣椒颜色的是类胡萝卜素，其中包括一部分胡萝卜素，但主要是叶黄素类的辣椒红素(Capsanthin，分子式C40H56O3)和辣椒玉红素(Cap sorubin，分子式C40 H56 O4)。

It was also found that beadlet carotenoids, especially anthaxanthin and lutein, had better antioxidative effectiveness compared to oil-soluble carotenoids.

同时乳化态的类胡萝卜素抗氧化效果较脂溶性的类胡萝卜素效果显著。

Carotene and bixin inhibited the of MCF-7 human breast cancer cell significantly. The effects of carotenoids were pleiotropic.β-Carotene can activate PPARγ signal pathway and regulate expression of the downstream and relative genes, and impel cytochrome C liberation from mitochndria and increase the level of reactive oxygen species in cell.

胡萝卜素与胭脂树橙显著抑制乳腺癌MCF-7细胞的生长，β-胡萝卜素的抑制作用可能是多效性的，一是激活PPARγ信号系统，调节PPARγ下游基因及相关基因表达，另一个是促使线粒体中的细胞色素C释放，引起细胞内活性氧生成增加，导致细胞活力下降或坏死。

The oxidation of methyl linoleate was inhibited by β-carotene, lutein and bixin in a dose-dependent manner. Lutein and zeaxanthin suppressed the hydroperoxide formation more efficiently than β-carotene and bixin at 41.7×10-6mol/L. Lutein inhibited the oxidation of methyl linoleate as efficiently as zeaxanthin.

表明β-胡萝卜素，叶黄素及胭脂树橙都按依赖于剂量的方式抑制亚油酸甲酯氢过氧化物的形成。41.7×10 -6mol/L的叶黄素及玉米黄质的抑制活性相近，高于β-胡萝卜素与胭脂树橙的活性，后两者活性近似。

The result shows that the greater positive influence is from the dissolutions of carotene and browning reaction,next come the cembratriendid compounds and hypoglycemia compounds,while the negative influence is from indoles,toluene and some aldehydes,and the negative influence from...

结果表明，对评吸结果影响较大的是胡萝卜素降解产物类和棕色化反应产物类；类西柏烷类和苯丙氨酸类中性致香物质的贡献较小；负面影响较大的成分主要集中在吲哚、甲苯及一些醛类上，类胡萝卜素降解产物类和棕色化反应产物类中的个别成分也有一定的负面影响。

Lycopene was osculant,β-carotene showed matroclinous and transgressive inheritance, so Liriodendron interspecific hybrids with fresher perianth segment could be selected by Liriodendron chinense ?

胡萝卜素表现为偏母超亲遗传，选用β-胡萝卜素含量高的鹅掌楸个体作母本进行杂交，有望选育出花色橙黄的杂交鹅掌楸个体。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。
