查询词典 pigment

The results showed that the ultrasonic extraction is a rather ideal method of extracting red P. tha fortuneana pigment. Cyanidin3glucoside can be hydrolysised to aglycon cyanidin under the conditions of 90℃, 9％HCl and 11min.Silica gel thinlayer chromatography with developping agent benzene∶ethyl acetate∶formic acid = 2∶2∶1 is better to separate cyanidin. Cyanidin is stable to heat and light, unstable to Zn2+ and Fe3+ and Cu2+, insensitive to Co2+ and Bi3+, befitting to acidic condition.

Callus deried from petiole explants of Panax japomcus ar. major produced three cyanidin glycosides as major anthocyanin pigments in darkness. Anthocyanin synthesis was remarkably stimulated by 2,4-dichlorophenoloxyacetic acid in combination with kinetin in MS medium. The pigment content of the callus reached up to 34. 14 mg/g fw.

从珠子参(panax japonicus ar.major)叶柄诱导的愈伤组织在暗培养条件下主要形成3种花色甙色素，且均以矢车菊素为甙元。2，4-二氯苯氧乙酸和激动素的组合能明显地促进色素的合成，色素含量可达34.14mg/g fw。

组分1、组分2和组分3在模1上得分与其在混合样品中的实际相对浓度具有良好的线性关系，相关系数分别达到0.98222，0.97865和0.99788，证实了利用三维荧光光谱和PARAFAC模型分类测量浮游植物浓度的可行性。

Original oils, in addition to three main contain glycerol, but also contains a small amount of free acids, phospholipids, sterols, and vitamins pigment composition, according to different needs, from using phospholipid, drying, deacidification, deodorizer, bleaching methods refined.

原始的油脂中，除主要含有三甘油酯外，还含有少量游离酸、磷脂、甾醇、色素和维生素等成分，可根据不同的需要，用脱磷脂、干燥、脱酸、脱臭、脱色等方法精制。

It is well known that retinal pigment epithelial cells are predominant proliferative cells in PVR which is an excessively wound healing response occurring after RPE cell wounding. The activated RPE cells migrate from their normal, sessile state to vitreous and onto both surfaces of the retina, in which they begin to dedifferentiate, migrate, proliferate, change phenotype and secrete ECM.

既往研究证明视网膜色素上皮(retinal pigmentepithelial，RPE)细胞是参与PVR的主要细胞，PVR是视网膜脱离后RPE细胞损伤的一种自我修复过程，是一种过度的眼内创伤修复反应；RPE细胞在正常位置上处于静止状态，而在某些病理条件下，如视网膜裂孔形成和视网膜脱离后，RPE细胞脱离原位，开始去分化、移行、增生、发生表型转化并分泌胶原等ECM，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

The oil content of too little, too much flour and may not be very good delivery pigment granules and remain in the formation of monlchamus in deink.

腮弓周围出现数个小隆起，这腮沟逐渐演变为外耳道，周围的小隆起则合并并逐渐变为外耳门，视网膜色素开始出现，使眼也变得更加明显。

Particularly it has unique advantage for drying polymers and resins; dyestuff and pigment; ceramics, glass; derust agent; pesticide; carbohydrate, dairy products; detergent and surfactant; fertilizer, organic compound, inorganic compound and so on.

在聚合物和树脂类；染料、颜料类；陶瓷、玻璃类；除锈剂、杀虫药类；碳水化合物、乳制品类；洗涤剂和表面活性类；肥料类；有机化合物、无机化合物液体物料的干燥上，表现得尤为突出。

First, removing protein by Sevage method. According to literature, it had best efficiency when polysaccharide liquid 2mg·mL~(-1) was treated with chloroform: n-butanol (3:1) and repeated for 3 times. Second, moving pigment with H_2O_2. In order to shorten the time and prevent the broken of structure of polysaccharide, the experiment was operated at 37℃. The following were dialyzation, concentration(60℃) and freeze-drying.

首先Sevage法除蛋白，根据文献，确定氯仿：正丁醇为3：1，多糖浓度2mg·mL~(-1)时，重复三次，除蛋白效果最佳；脱色采用了双氧水氧化法，为加快脱色时间，又要避免双氧水对多糖结构的破坏，实验在37℃下进行；透析、浓缩、干燥过程同样为了保证多糖结构的完整性和提取后物质疏松易溶解，先透析，然后60℃浓缩，最后是冷冻干燥。
