Vitamin E is an antioxidant that helps neutralize superfluous free radical, which was generated by exposure to sunlight, pollution, radiation, pressure etc. In addition, it helps prevent arterial disease, lower the haemoconcentration, repair damaged tissue, and moisturize and nourish skin, delay ageing.

维生素E是一种强抗氧化剂，有助于中和人体因日晒、污染、放射物、压力等产生的过量自由基，可防止动脉疾病，降低血液浓度，修复损伤组织，滋润肤质，延缓衰老。

The results indicated that 40% ethanol and water can dissolve Berberis heteropoda pigment better; the pigment is stable in acidic condition; iron ion can increase the absorbency of the pigment; the influences of reducing agent is greater than oxidizer＇s.

结果表明，小檗色素在40％的乙醇溶液及水中的溶解效果最好；在酸性条件下色素较稳定；铁离子对其有增色作用；氧化剂、还原剂对色素稳定性均有影响，其中以还原剂影响较大。

This essay focuses on the extraction of Berberis heteropoda pigment with different impregnants, the influences that different pH condition and different mentalion take on the Berberis heteropoda pigment＇s stability, as well as that oxidizer and reducing agent take on its stability.

研究了不同溶剂对小檗色素的提取效果，以及不同pH、不同金属离子、氧化剂和还原剂对该色素稳定性的影响。

The pigment of Berberis heteropoda Schrenk is a type of anchocyanin and it is strong in resistance against light and to some extent, good in enduring heat and low consistence oxide. But it is poor in resistance against reductant and preservative. It can be applied to the condition of PH. It is also found that sucrose and most of metal ions do not exert negative effects on the stability of the pigment, except Fe3+, Fe2+and low consistence Pb2+, which have some extent effects. Adding stability matter can improve its stability. The harm trace elements contains are within requirement of the National Standard on food safety, As the lexicological study indicates that the pigment does not have any toxicity and mutagenesis, it can be used as edible pigment.

结果表明：大孔树脂吸附-解吸附法纯化黑果小檗色素实验室工艺简单易行，色素回收率高；黑果小檗色素属于花色苷类色素；耐光性好；对热有一定耐受性；对低浓度氧化剂有一定耐受性；耐还原性差；对防腐剂耐性差；适用PH＜6条件下使用；蔗糖和大多数金属离子对色素无不良影响，但Fe~(3+)、Fe~(2+)、Sn~(2+)和低浓度pb~(2+)对色素有影响，加入稳定剂后，可提高色素的耐热性、耐氧化性、耐防腐剂能力；经对有害微量元素进行检测和毒理试验表明，该色素安全无毒，可以作为天然食用色素使用。

It contains vitamin c, antioxidants, hyaluronic acid, but its main ingredients are peptides.

它包含维生素C ，抗氧化剂，透明质酸，但其主要成分是多肽。

Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali; UHMWPE has a fine corrosion resistance to inoxidable acid (dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid), ammonia, amine and various alkali and salty solutions. Both materials can't resist the corrosion of strong oxidable acid.

在常温下，PVF2对卤素、卤代烃、强氧化剂、沸酸、碱等多种有机溶剂都有良好耐蚀性；UHMWPE对非氧化性酸(稀硫酸、硝酸及浓度较大的盐酸、磷酸、氢氟酸、甲酸、乙酸)、氨和胺及各种碱、盐溶液都有良好的耐蚀性，两种材料都不耐强氧化性酸的腐蚀。
