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"。

The selective absorption of carotenoids and the specific interaction between carotenoids during their absorption which people focus attention upon are discussed.

细胞对β-胡萝卜素的摄入和分泌表现出浓度依赖性、时间依赖性和饱和性；对不同类胡萝卜素的吸收表现出选择性；类胡萝卜素在吸收过程中表现出相互影响。

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。

Innovations in commercializing cheaper sources of carotenoids are expected to reduce the cost of producing carotenoids.

找到便宜的类胡萝卜素原料，并使之商品化，有望减少类胡萝卜素产品的生产成本。

The carotenoids may prevent the carcinogenesis of BQE indued hamster oral cancer by act as suppressor inhibiting the expression of PCNA and CK14. By the way, the anti-cancer mechanism of different carotenoids may be not the same pathway.

类胡萝卜素能预防口腔癌症的发生，在细胞增殖、细胞异常化生、乳突瘤和恶性肿瘤病灶中PCNA和CK14的表现降低，而不同的类胡萝卜素之间预防癌症的机制可能不尽相同。

There are different views about the mechanism of carotenoids absorption.

关于类胡萝卜素的吸收机制说法不一，目前体外培养的细胞模型被广泛用于类胡萝卜素的吸收研究。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
