Now the known species of luciferin was variety,which had large differences on structure?property and synthesis.At present the research is focus on the biosynthesis of luciferin.

现在已知的荧光素种类繁多，不同来源的荧光素在结构、性质与合成上大不相同，荧光素在生物体内的生成问题是目前研究的焦点。

In the biological area developed a world-leading levels of biological air purification pad, biological Penetrant, chitin textiles

在生物领域开发出了具世界领先水平的生物空气净化垫、生物渗透剂、甲壳素纺织

Short chain fatty acid, propyl alcohol, methionine and dimethylamide are the possible precursors for spiramycin formation. Addition of 0.6% propyl alcohol into fermentation medium increases the spiramycin productivity by 24%, while addition of short chain fatty acids, methionine, or dimethylamide has a repression effect on spiramycin production.

合成螺旋霉素的前体物质可能有短链脂肪酸、丙醇、蛋氨酸和二甲胺等，在发酵培养基中加入0.6％的丙醇可以使螺旋霉素的发酵单位提高24％，而短链脂肪酸、蛋氨酸和二甲胺对菌体生长和螺旋霉素的生物合成有不同程度的抑制作用。

By the catalyzed of F3H, F3'H and F3'5'H, the biosynthesis of anthocyanins branched three pathway to form pelargonidin, cyanidin and delphinidin separately. DFR, F3'H and F3'5'H are the most important genes for introducing new metabolic branches by genetic transformation to plants that lack some kinds of flower pigments.

花色素苷的生物合成主要由于F3H，F3'H和F3'5'H三个关键酶的作用形成3个分支，最终分别生成橙色到砖红色的天竺葵素糖苷，红色的矢车菊素糖苷和蓝色到紫色的飞燕草素糖苷，因此， F3'H，F3'5'H和DFR基因是利用遗传转化引入花卉植物原本缺乏的花色代谢途径的关键基因。

Characteristics of Inclusions: After the tea is kept for a long period of time in a stall and deep fermentation processing begins, the specialties of material and manufacturing make many bioreactions occur for thorough activation of microbes to excrete extra-cellular enzymes, which impacts over 500 stuffs of tea. Theses microbes contain catechin, polyphenols, amylase, cellulose, protein, lipid ,alcohol, ketone, vitamin, microorganism, and organic acid, making them transform, isomerize and degrade, polymerize and couple, so as to produce amylase, thearubigins, theaflavins, cellulose, and microelements that other commercial teas could not produce or produce too little.

三、 内含物的特点：由于原料、制造的特别性，经长期陈化和深发酵的过程，茶叶内含物发生多种生物生化反应，充分激活微生物分泌胞外酶，作用于茶叶中的内含儿茶素、多酚、多糖、纤维素、植物素、蛋白质、脂类、醇类、酮类、维生素、微量元素、有机酸等500多种物质，使之转化、异构降解聚合耦联，生成其他商品茶无法比拟和缺乏的多糖、茶红素、茶黄素、纤维素、微量元素等，并形成以菇稀醇类为主体香气。

The study is possible for experimenters to offer theoretic direction while developing new type quercetin metal complex with higher activity antioxidants. At the same time, the study offer theoretical foundation that quercetin can be used as a kind of antidote for superfluous meatal ion in body.

本文通过对槲皮素金属配合物的合成、生物活性及其量子化学的较深入地研究，为进一步寻找高效、低毒的抗氧化性槲皮素配合物提供了一定的参考价值，同时为槲皮素可作为体内过多金属离子的解毒剂提供了依据。
