天然染料是指自然界植物、动物或矿物中含有丰富色素且具有染色价值的天然材料，也包括从这些天然材料中提取色素制成的利于环保、益于健康的有机染料。天然媒染剂是指在染色过程中，使色素和纤维增强染着亲和力的酸、碱、蛋白质、单宁或金属离子等天然媒介物质。由于大多数天然染料属于媒染染料，在其染色中媒染是不可缺少的工艺步骤，需要通过天然媒染剂，运用先媒染、中媒染、后媒染或同浴媒染等方法，使色素渗入、定着于纤维中，达到发色和固色的目的。

本文以苹果籽壳为原料，首次研究了天然苹果籽壳色素的提取和光谱学特性，并考察了金属离子、pH值、光照、温度、氧化还原剂以及常用食品添加剂对其稳定性的影响。结果表明，苹果籽壳色素易溶于碱性水溶液，不溶或者难溶于非极性溶剂。紫外-可见光谱分析表明，色素在264 nm处有吸收峰。稳定性试验表明，色素易与二价或者三价金属离子形成沉淀，在偏酸至中性范围内较稳定，对光、热、氧化剂、还原剂以及各种食品添加剂耐受性强。该色素有望开发成为安全可靠的天然植物色素添加剂。
The extraction, spectroscopy characteristic of the pigment from apple seed shells were studied for the first time, and the effects of different factors (such as metal ions, pH, light, temperature, oxidants, reducing agents and food additives) on the stability of the pigment were also investigated. The results were as follows: The pigment was soluble in alkaline solution, insoluble or poorly soluble in nonpolar solvents. The UV-visible spectrum analysis revealed that there was an apparent absorption peak near 264 nm. The pigment solution was easily precipited when some divalent and trivalent metal ions were added. In addition, it was suitable for use in acidic and neutral conditions and could be relatively stable for light, temperature, oxidants, reducing agents and some kinds of food additives. Therefore, the pigment from apple seed shells was a kind of safe and reliable natural plant pigment.

Controversy on environment and food safety of transgenic products mainly focused on its containing antibiotics and herbicides-tolerant genes as selectable marker genes in recent years. Therefore, it is necessary and urgent to find safer and more efficient marker genes as alternatives. Some pigments, such as anthocyanin, synthesis in plants are controlled by anthocyanin synthesis enzymes and transcriptional regulatory factors. Some studies have demonstrated that visible color changes occurred in transformed phenotype by introducing these genes into plants. In addition, the products or intermediate products in anthocyanin biosynthesis pathway are all natural pigments which are benefitial to human health. Therefore, the genes or transcriptional regulatory factors responsible for anthocyanin biosynthesis could be used as selectable marker gene in plant transformation. In this paper, we gave a brief introduction of the research progress on plant transformation with visible marker genes, whi
