Four kinds of main carotenoids from Ipomoea batatas were determined by external standards.

以外标定量法对红心薯中的4种主要类胡萝卜素(β-胡萝卜素，叶黄质，堇黄质，新黄质)进行了定量，结果较为满意。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

本文对鹅掌楸、北美鹅掌楸和杂交F_1的花果共11 个数量性状进行分析，并应用高效液相色谱对上述三大类群花被片类黄酮糖苷配基和结合糖及类胡萝卜素进行了定性和定量研究，结果如下：鹅掌楸和杂交鹅掌楸花被片类黄酮糖苷配基为花青素、6-羟基黄酮和反式查尔酮，糖苷配基结合糖为葡萄糖、鼠李糖和半乳糖；类胡萝卜素为β-胡萝卜素和番茄红素。

By feeding with the n-carotene of 0, 0.5, 1.0, 1.5, 2.0 and 2.5 g/kg diet, the influences of β-carotene on the body colour of the 450 red-white koi carps (Cyprinus carpio L.) and the deposition position of n-carotene in the carp body were investigated by the spectrophotometer method.

通过投喂含有β-胡萝卜素为0、0.5、1.0、1.5、2.0、2.5g/kg的人工配合饲料，采用光谱法，对β-胡萝卜素对450尾红白锦鲤体色的影响及其在体内的沉积部位进行了研究，并用色谱方法对β-胡萝卜素在体内的色素组分进行了研究。
