This product not only contains carotin, VA , niacin, ascorbic acid,lactochrome, linolic acid , medlar polyoses, calcium, phosphorus, iron, and protein etc, but also is replenished with red chinese date ( containing protein, polyoses, VC and other vitamins, CAMP, and ursolic acid etc) and seabuckthorn ( containing VA, VC,VE,VK,VB1,VB2, flavonoid, and coumarin etc.), which make it more nutritious and easier to be absorbed by the body.

枸杞红素不仅保留了枸杞中的胡萝卜素、维生素A、烟酸、抗坏血酸、核黄素、亚油酸、枸杞多糖、钙、磷、铁、蛋白质等成分，而且因添加了红枣（含有蛋白质、多糖、维生素C等多种维生素、环磷酸腺苷及熊果酸等成分）、沙棘（含有维生素A、C、E、K、B1、B2、黄酮类、香豆素等成分）使其营养成分更加丰富并且更容易被人体均衡吸收。

ALP would play a role in improving antioxidative ability of body,decreasing the damage of free radical to the body and maintaining the body weight of normal adult mice.The antioxidation of ALP maybe relate to Se,Vitamin E,β- carotin and flavonoids that ALP contained. 2.ALP has the different antioxidative mechanism from that Vitamin E has.

ALP 能提高正常小鼠血中 GSH-Px 活力及 SOD 活力，降低其 MDA含量(P.05)，有效防止受辐射成年小鼠血及肝脏中 GSH-Px 活力的降低和 MDA 含量的增加(P.05)，因此具有抗辐射、抗氧化的作用，ALP的抗氧化功能可能与其所含的硒、维生素 E、β-胡萝卜素以及异黄酮类物质有关。2。

The rose gene has not produced "the flavonoid 3'5'- hydroxide enzyme" which the blue color delphinium Colored pigment needs, therefore the blue rose was considered is not impossible, thus English blue rose has "is impossible" meaning.

玫瑰花基因没有生成蓝色翠雀花素所需的"黄酮类化合物3'5'-氢氧化酶"，因此蓝玫瑰被认为是不可能的，因而英语blue rose有"不可能"之意。

Based on the previous literatures, the following major innovation works were carried out in this dissertation:(1) The derivatization reaction conditions of ephedrine and pseudoephedrine with sensitive derivation reagent in aqueous system were studied and two new methods were developed for the assay of them by microemulsion electrokinetic chromatography and micellar electrokinetic chromatography with LIF detection. The sensitivity and analysis times were greatly improved compared with the previous reports;(2) A new method of CZE with indirect LIF detection was developed for the simultaneous determination of six coumarin compounds (esculin, esculetin, isofraxidin, genistein, naringin and sophoricoside) with fluorescein as the probe. The proposed method enlarges the application range of LIF detector, and provides new approach for the analysis of certain compounds difficult to derivatize;(3) Based on the above research, an MEKC with indirect LIF detection method for the simultaneous determination of adenine and guanine in DNA extracts from fungus, maize and soybean was established;(4) A new method for the investigation of the complexes formed between human serum albumin and ampicillin sodium under the simulated physiology conditions using laser light scattering technique was developed.

该论文在综述前人工作的基础上，开展了如下未见文献报道的创新性的研究工作：(1)使用灵敏的衍生试剂对麻黄碱和伪麻黄碱在水体系中的衍生反应条件进行了系统研究，建立了微乳电动色谱-激光诱导荧光检测法和胶束电动色谱—激光诱导荧光检测法测定麻黄碱和伪麻黄碱的灵敏分析新方法，与以前的报道相比，灵敏度和分析时间均有很大改善；(2)使用荧光素钠作为背景荧光试剂，建立了同时分析测定六种黄酮类化合物(秦皮甲素、秦皮乙素、异秦皮定、染料木素、柚皮苷和槐角苷)的毛细管区带电泳—间接激光诱导荧光检测新方法，扩大了激光诱导荧光检测的应用范围，对难衍生化合物的分离分析提供了一种新思路和新途径；(3)以荧光素钠作为背景荧光试剂，建立了一种用于同时测定食品提取DNA中的腺嘌呤和鸟嘌呤含量的胶束电动色谱—间接激光诱导荧光检测新方法；(4)用动态和静态激光散射法研究了模拟生理条件下人血清白蛋白与氨比西林钠盐相互作用所形成的复合物，为药物分子与蛋白质的相互作用、药代动力学等的研究提供了一种新思路。
