Analysis of the material change, garlic cells bioactive aliphatic thio cysteine sulfoxide and thiosulfate propenyl cysteine sulfoxide sulfur compounds in garlic, such as the role of enzymes, the generation of thiobarbituric acid sub - ester, propylene-based thiosulfinates, allyl thiosulfinates as garlic pigment precursor substances, and further changes occurred in the green garlic.

从物质变化分析，大蒜细胞中的生物活性物质硫代脂肪族半胱氨酸亚砜和硫代丙烯基半胱氨酸亚砜等含硫化合物在蒜酶的作用下，生成硫代亚磺酸酯、丙烯基硫代亚磺酸酯、烯丙基硫代亚磺酸酯，作为大蒜色素物质的前体，进一步发生大蒜绿变。

Both Pro40 and Va145 are situated at a critical positions of cytochrome 〓 and play significant role on the structure, propery and function of this electron transfer protein.

可见，Pro40及Va145处在细胞色素〓的十分重要的位置上，对该电子传递蛋白的结构、性质和发挥功能具有重要作用。

Methods Reverse hemagglutination test was used for identification of Fral. The Y. pseudotuberculosis sensitive to PstI and the bacteriostastic ring were used for identification of PstI. The low-calcium medium was used for identification of Vwa and Jackson-Burrows medium was used for identification of Pgm.

采用反向间接血凝试验检测FraI；利用假结核菌对PstI敏感可产生抑菌环的复盖种子层法检测PstI；采用乏Ca(上标 2+)时37℃鼠疫菌不能生长观察Vwa，利用色素培养基观察Pgm。

It is known as pudendum itches at the early days, with the symptoms such as vagina red and turgescence or itches, its skin thickens, sometimes there is lichen-like pathological changes comes up, and even the pigment of skin falls off.

初期称外阴瘙痒症，症状为外阴红肿、瘙痒、皮肤增厚、可有苔癣样病变出现，皮肤色素脱落。

Extracts the Pyracantha fortuneana red pigment with soaking the acidic edible 70% ethyl alcohol,and conducts the research to this pigment stability.

因此，探求并开发天然食用色素资源是食品科学领域极有吸引的研究方向之一，具有重要的经济价值和社会意义。

There are variety of B vitamins in wheat grain, such as thiamine, riboflavin and pyridoxine. The objective of this study was to understand the content of B vitamins (thiamine, riboflavin and pyridoxine) in colored grain wheat, and their Patterns of variation, and provide a theoretical basis for optimization of B vitamins content in wheat breeding.

小麦籽粒含有多种B族维生素，本研究通过测定24个不同粒色的小麦品种中维生素B1、维生素B2、维生素B6及籽粒色素含量，并研究不同颜色的小麦籽粒中B族维生素含量与小麦籽粒颜色的关系及其变异规律，为B族维生素的利用及小麦品质育种提供依据。

The oxidation mechanism of synephrine was also investigated;(2) The electrochemical behavior of twelve flavonoids (quercetin, morin, fisetin, luteolin, isorhamnetin, myricetin, hyperoside, quercitrin, puerarin, farrerol, naringenin and hesperidin) was investigated. The method for the determination of flavonoids was developed by using different pulse voltammetry, and the detection limit was in the range of 10-7~10-9 mol/L. This method has been successfully employed to determine the total amount of flavonoids in pericarpium citri reticulatae and quercetin in the spiked human blood plasma samples.
