Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.

结果表明，1，拟南芥AtSIRT1与人的同源蛋白hSIRT4相同，定位于线粒体，可能参与呼吸作用和电子传递，SIRT2与人的同源蛋白hSIRT6相同，定位于细胞核，可能同它的功能类似，在延缓衰老及调节细胞寿命方面起作用。2，AtSIRT1突变，可引起幼苗和植株的子叶变黄和早衰；AtSIRT2突变，可引起叶片发紫，沉积大量花青素。3，SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体，说明Sirtinol在拟南芥中的作用机制不同于其他生物。4，AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似，揭示其功能的相似性。5，在大肠杆菌中过量表达了其中一个基因(AtSIRT2)，可体外检测其酶学活性，进一步证明其功能。

Result:The best prescription was : Lecithin: Sodium Cholate =8∶1,Lecithin:Proanthocyanidins =15∶1,sonde-type ultrasound time was 5 min,the entrapment efficiency of FNL was 67.13%,and the results revealed the FNLs were sphere like with the mean size of 168.3 nm,the mean Zeta potential was –86.6 mV.

结果：最佳处方和制备工艺条件为卵磷脂与胆酸钠的质量比为8∶1、卵磷脂与原花青素的质量比为15∶1、探头式超声5 min。包封率为67.13%，所得柔性纳米脂质体为类球形实体粒子，平均粒径168.3 nm，平均Zeta电位-86.6 mV。

Professor Corder concludes: The traditional production methods used in Sardinia and south western France ensure that the beneficial compounds, procyanidins, are efficiently extracted.

Corder教授总结出在撒丁岛和法国的西南地区使用的传统的酿酒方式能保证原花青素被有效地萃取出。

Color may also be modified by traces of iron and other metal salts and organic substances, for example cyanin is red in roses but blue in the cornflower.

此外一些微量的离子，金属盐以及其他的有机物质也可以改变其显色，例如花青素在玫瑰中显红色而在玉米花中显蓝色。

Cy3G was one of important red-series anthocyanins, soCy3G would play a significant role in true-red crape myrtle breeding.
