High performance liquid chromatographyanalysis showed the mango fruit of these two cultivars contained 3 carbohydrates, 11 organic acids and 4 carotenoids. The carbohydrates were composed of fructose, glucose and sucrose; the organic acids were oxalic acid, tartaric acid, quinin acid, malic acid, ascorbic acid, lactic acid,α-ketoglutaric acid, citric acid, fumaric acid, succinic acid and gallic acid; the carotenoids were violaxanthin,β-carotene, lutein, lycopene.

高效液相色谱分析表明，芒果果实共含3种糖、11种有机酸和4种类胡萝卜素，即果糖、葡萄糖和蔗糖；草酸、酒石酸、奎尼酸、苹果酸、抗坏血酸、乳酸、α-酮戊二酸、柠檬酸、富马酸、琥珀酸和没食子酸；堇菜黄素、β-胡萝卜素、叶黄素和番茄红素。

The result indicates that the best method for extracting β-carotene is to saponify the test specimen one hour with 4% NaOH methyl alcohol solution in 60-70'c and then to separate with 3:7 acetone-benzine component solvent as extraction solvent, MgO as the absorbent, the acetone-benzine as the eluent. Extracted solvent has been determined in the color dish condition (1cm) by ultraviolet spectrophotometer at 447 nm. The result shows that the β-carotene in carrotis 0.134 mgg^(-1), 0.0863mgg^(-1) in red pepper and 0.0426 mgg^(-1) in spinach.

结果表明，比较优先的β-胡萝卜素提取方法是：试样用4% NaOH甲醇溶液在60℃~70℃皂化1h，用3：7的丙酮－石油醚混合溶剂提取，以Mgo为吸附剂，丙酮－石油醚为洗脱剂分离，提取液用紫外分光光度计在波长447nm，1cm比色皿条件下测定，得出蔬菜中β-胡萝卜素含量：胡萝卜为0.134mgg^(-1)，红椒为0.0863mgg^(-1)，菠菜为0.426mgg^(-1)。

The transformed cell could be agglutinated by lower concentration of ConA and could grow in semisolid agar.

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。

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。

This product not only contains the various nutrients in the carrot such as vitamins,β-carotene (converting to vitamin A in vivo), protein, active enzymes, minerals (potassium, sodium, calcium, magnesium, iron and zinc) but also is replenished with concentrated carrot essence and red tomato (containing abundant vitamin A, B, C, potassium, sodium and magnesium), which makes it more nutritious and easier to be absorbed by the body. It is the indispensable natural healthy food for the modern.

胡萝卜素不仅保留了胡萝卜所含有的多种维生素、β-胡萝卜素（在体内可转化为维生素A）、蛋白质、活性酶和矿物质（钾、钠、钙、镁、铁、锌）等营养成分，而且因添加了适量的胡萝卜浓缩素、红番茄（含丰富的维生素A、B、C及矿物质磷、钾、钠、镁等营养成分），使其营养成分更加丰富并且更容易被人体均衡吸收，是现代人不可缺少的健康食品。

Close correlation was also found between the SOD activity and the cell density and substance accumulation. When SOD activity is higher or lower than 0.710×10^8 cells^(-1)min^(-1), the cell density and accumulation of 13-carotene and protein were lower. When SOD activity reached 0.710×10^8 cells^(-1) min^(-1), the cell density, and accumulation of β-carotene and protein were the highest.

盐藻SOD活性与细胞密度及物质积累关系密切：在SOD活性为0.710×10^8 cells^(-1)min^(-1)左右时，盐藻细胞密度、β-胡萝卜素和蛋白质的积累量都最高，而在SOD活性较低或较高时，盐藻细胞密度、β-胡萝卜素和蛋白质的积累量都较低。
