For example Jie carotene and tomato red, while the opposite is carotene, lutein also contains functional fragments such as a typical representative of a hydroxyl group, an epoxy group and an oxo group. lutein group was canthaxanthin (canthaxanthin), . zeaxanthin and astaxanthin under insect astaxanthin is 3,3 - dihydroxy -p, P- carotene 4,4, - synthetic astaxanthin dione CAS number is 7542-45-2 and its non- enantiomer (3S, 3'S), (3R, 3, S) and (3R, 3, R) 1: 2:. mixture 1 isolated from natural sources of astaxanthin CAS number is 472-61- 7. Astaxanthin is a pigment, it was found that in many crustaceans (Crustaceae) such as normal-worm in (// o attach an ^ gammarws), found in salmon (Sa / amo s "/ ar), and flamingo feathers found (for example, P / zoewcc ^ en ^ n ^ Z? er). astaxanthin is mainly used for all kinds of animals, especially salmon, trout, shrimp, sea bream, fish and poultry Servo feed ingredients. Recently natural astaxanthin is also used as food, nutraceutical or cosmetic additives with antioxidant properties. astaxanthin may be obtained by fermentation (Biotechnol. Letters 10 (1988) 609-614), or from WO -A89 / 1997 and EP329754 disclosed microalgae obtain .WO-A86 / 6082 describes a method for separating from a natural source of astaxanthin, which is from crustacean shells carried out by extraction .US2004253664 describes the use of eukaryotic microbes into 4 right foot carotenoids, lutein and preparation of apo carotenoids. alternative sources of extraction of natural astaxanthin is Aquasta ™, its proprietary plant by wiping the yeast Phaffia yeast prepared the product obtained further astaxanthin is using chemical synthesis, such as described in US 5,654,488. 使用少量（通常约50pl-1000|il的虾青素有机溶剂溶液）虾青素结晶形式进行的扫描是在试管或孔板皿（well plate cups)中进行的，通过加入反溶剂或者通过蒸发而使试管/皿中的虾青素结晶，通过测量它们的特征拉曼光谱、X-射线粉末衍射图以及其它物理参数来确定晶体的结构。 Use a small amount (typically about 50pl-1000 | il of an organic solvent solution of astaxanthin) scanning the crystalline form of astaxanthin is conducted in a test tube or plate dish (well plate cups) carried out by the addition of anti-solvent or by evaporation The tubes / dish astaxanthin crystal, by measuring their characteristic Raman spectroscopy, X- ray powder diffraction pattern and other physical parameters to determine the crystal structure. 使用少量基本上包含多种水平的不同类胡萝卜素化合物的虾青素进行受控制的结晶，出乎意料地产生两种分别形成或者在混合物中一起形成的不同奸青素晶型。 Use a small amount of astaxanthin essentially comprises a variety of different levels of carotenoid compounds were controlled crystallization, unexpectedly produce two different rape are formed or astaxanthin crystal form in the mixture formed together. 通过将所测定的拉曼光谱与两种晶型在几个已知重量比的"最佳配比"下的平均单独光谱进行比较，从而确定晶型混合物中单独晶型的含量。 Measured by the Raman spectra and two crystal forms in several known weight ratio of the average individual spectra "optimum ratio" under are compared to determine the crystal mixture in a single crystal of content. 两种单独晶型在混合物中的存在是在"最佳配比" 的特征拉曼光谱中反映出来的，其中除了单独晶型I和晶型II的光语峰以外，没有观察到另外的特征峰。 Two separate crystal presence in the mixture is reflected in the "best ratio" feature Raman spectrum, which in addition to a single crystal type I and type II crystal light language peak was not observed Additional features peak. 考察与工业中使用极性、非极性、质子惰性和质子性溶剂进行的溶剂除去和晶体回收相关的因素，其涉及对虾青素的毒性（例如溶剂残留）、溶解性以及稳定性。 Investigation and industry use of polar and non-polar, aprotic solvent and protic solvent removal and recovery factors associated crystal, which involves the toxicity of astaxanthin (such as residual solvent), the solubility and stability. 它们意外地显示虾青素晶型i或n的形成是独立于所使用的溶剂或结晶方法的，但其实质上取决于类胡萝卜素化合物的存在和浓度。 They unexpectedly showed formation of astaxanthin crystal type or n i is independent of the use of solvents or crystallization process, but it essentially depends on the presence and concentration of carotenoid compounds. 出乎意料的是，虾青素可以以两种不同的晶型存在并且作为两种晶型的混合物出现，这取决于制备晶体的条件。 Surprisingly, astaxanthin can be in two different crystal forms exist and appear as a mixture of two crystal forms, depending on the conditions for preparing the crystal. 这些内容清楚地表明两种工业应用的晶型以及两种晶型的混合物可以在控制的条件下从虾青素的溶液中制备。 These contents clearly show polymorphs as well as mixtures of two industrial applications of two crystal forms can be prepared from a solution of astaxanthin under controlled conditions. 制备用于鱼饲料和营养品应用以及生命科学工业中其它分支的虫下青素组合物的已知技术，没有披露制备特定晶型以及特别是两种晶型混合物的可能性，所述特定晶型以及两种晶型混合物明显的特征在于X-射线粉末衍射图和拉曼光谱，以及至少一种其它物理参数例如熔点、在有机溶剂中的溶解度、DSC扫描。 Preparation for the next application of fish feed and nutrition and life sciences industry in other branches of insects known techniques astaxanthin composition, the possibility of the preparation of a specific polymorph and in particular the two crystal mixture did not disclose the specific crystal type and a mixture of two distinct polymorphs wherein X- ray powder diffraction pattern and Raman spectroscopy, and at least one other physical parameter such as melting point, solubility in organic solvents, DSC scan. 晶型在有机溶剂和油中具有不同的溶解度，这使得加工和配制虾青素组合物时有了更宽泛的选择。 Polymorphs have different solubility in organic solvents and oils, which makes processing and have a wider choice when astaxanthin compositions may be formulated. 而且，在口服给药之后，晶型可以影响体内的溶解速率并且允许在油性给药媒介中更高的（过饱和的）浓度，这可以提供更高的吸收和生物利用度。 Further, after the oral administration, the crystal form can affect in vivo dissolution rate and allow administration in an oily medium higher (supersaturated) concentration, which can provide a higher absorption and bioavailability. 虾青素晶型的X-射线衍射图是使用BrukerD8改进型记录的。 Astaxanthin crystal form of X- ray diffraction patterns are recorded using BrukerD8 improved.
