青色素

ABSTRACT］ Objective To assess the safety of sweetpotato anthocyanin.

目的 对青紫薯色素安全性进行评价。

After 2 months, the samples of skin, scale, head and fm ray of the carps were selected for the subsequent analysis of determining their total carotenoid contents and the absorbance values, so the above solutions were evaporated to dryness, and then were measured by the thin layer chromatography. The results show that the spectrum of total pigment of koi carp had two absorption peaks in visible light (454 nm and 470 nm). The growth rate, weight gain and specific growth rate of red-white of koi carp fed with 1.0 g/kg β-carotene tended to be obviously higher than the control group (P.05), while the FCR of groups fed with 1.0~2.5 g/kg β-carotene was significantly lower than the control group (P.05). The colouring of red-white and red region in koi carp was the best at 1.5~2.0 g/kg β-carotene in diet, while the n-carotene added in the diets did not have any effects on total carotenoid concentration of skin/scale of white region. The n-carotene mainly deposited in skin and fin ray. And it mainly transformed into astaxanthin in koi carp.

结果表明，红白锦鲤总色素光谱在可见光区（454nm和470nm）有两个吸收峰，β-胡萝卜素在1.0g/kg组的增长率、增重率、特定增长率显著高于对照组(P.05)，1.0~2.5g/kg各组的饵料系数均显著低于对照组(P.05)；对于鲤的红白和红色区域，β-胡萝卜素的添加量为1.5~2.0g/kg时，对红白锦鲤体色的增色效果最好：β-胡萝卜素对红白锦鲤白色区域总类胡萝卜素的含量影响很小；β-胡萝卜素在红白锦鲤体内的主要沉积部位是皮肤和鳍条；β-胡萝卜素在红白锦鲤体内主要转化为虾青素。

OBJECTIVE To investigate the effects of Folium Isatidis on the activity and mRNA expression of CYP2E1 in mouse liver microsome.

目的：了解大青叶对细胞色素P450 2E1(CYP2E1)酶活性及其信使核糖核酸表达的影响。

As a result penicillium of Ma Erni humble is double photograph bacterium, mould bacterium colony can discover the broom shape mycelial of diagnostic sex,; of pigment of rose of water-solubility of the generation after sanded Paul fosters 3 days is medullary inside and outside of cell of blood of the week outside mixing all can discover spore;PAS coloring sees bacterium body show circle, elliptic or sausage shape, size is differ, it is 2~8 μ M about, color of afterbirth wall incarnadine and clear and successive, it is thus clear that inside the cell of sausage shape one apparent horizontal stroke is lain between, afterbirth is qualitative not easy and chromatic.

结果马尔尼菲青霉菌为双相菌，霉菌型菌落可发现特征性的扫帚状菌丝，沙保罗培养3天后产生水溶性玫瑰色素；骨髓和外周血细胞内外均可发现孢子；PAS染色可见菌体呈圆形、椭圆形或腊肠状，大小不一，约为2~8μm，胞壁染红色且清楚连续，在腊肠状的细胞内可见一明显的横隔，胞质不易着色。

Staining of ancient China is contained in natural plant pigments, such as the indigo blue dye.

我国古代染色是采用天然植物中所含的色素，如染青蓝色的靛蓝。

The results from the fact that it is not affected by cyanine-glycoside,what it contains and from which it derives its color,as well as the factors such as temperature,oxygen,light and acid.

而它具有着这一特征是由于它不受花青甘色素的影响，它包含并从中产生的颜色以及其他的因素，例如：温度、氧气、光线和酸。

The results showed that the chemical properties of two kinds of Perillas were quite different; Pigment stability of Japanese red Perilla to heat and light was better than that of local Perilla.

结果表明：不同种类紫苏的水溶性色素物质的化学性质有较大差异，红紫苏色素对热、光等的稳定性及多酚类物质含量、色素含量、抗氧化活性均高于紫青紫苏。

Methods The experimental mice were given 200 g/L sweetpotato anthocyanin with a dose of 36 mL/kg, three times a day, for 14 days. Body weight and death rate were recorded. The mutagenicity of sparfloxacin on CHL cell in the presence and absence of S9mix was evaluated.

采用最大给药量试验，小鼠每天3次、每次36 mL/kg灌胃给予200 g/L的青紫薯色素水溶液14 d，观察其体质量变化和死亡情况；以仓鼠肺成纤维细胞行染色体畸变试验，对青紫薯色素进行毒理学评价。

This pigment is soluble in acid water, alcohol and methanol. The pigment is bluish-green in neuter and yellow under alkaline conditions. The maximum absorptive peak of ultraviolet-visible spectrogram of the pigment is at 530~540 nm.

该色素易溶于酸性的水、乙醇、甲醇，色素在酸性条件下显红色，在中性和碱性条件下显青绿色至黄色；色素在530~540nm处有最大吸收峰；最佳提取溶剂为pH2的55%乙醇溶液。

By using competitive adsorption of activated carbom to remove unfavorable influence of carbon in carbonaceous gold concentrate on leaching process, the leaching rate of gold concentrate can be improved to 88% as compared with 10%by direct cyanidation.
