Introduction: Natural astaxanthin also known as astacin, is a kind of precious health ingredients, is used for development to enhance immunity, anti-oxidation, anti-inflammatory, eyes and brain health, regulating blood lipids and other natural and healthy products. At present, the main used as a raw material for human health food and medicine; aquaculture (currently the main salmon, trout and salmon), poultry feed additive and additives of cosmetics. It can significantly improve the body's immunity, because of its non-specific combination with skeletal muscle, can effectively remove the free radicals which are generated by the movement of the muscle cells, strengthen aerobic metabolism, so it has a significant anti fatigue effect.

3.1 Methods of Manufacturing
71, 9 g (0, 125 mol) ASTAXANTHIN-C15-PHOSPHONIUMSALZ P5 (X~ = BRO- mid) wurden in 150 ML Methanol vorgelegt. Bei 0C gab man 11, 4 g GIO-DIAL Ia (95percent ig ; das entspricht 0, 0475 mol) zu. Dann tropfte man innerhalb von 1H bei 0C 24, 8 g einer 30percent igen Lsung von Natriummethylat in Methanol (= 0, 137 mol NaOMe) zu, rhrte eine weitere Stunde bei 0C nach und lies dann auf Raumtemperatur kom- men. Man tropfte eine Lsung von 1, 5 G (25 mmol) Essigsure in 115 ml Wasser zu, erhitzte auf Rckfluss (ca. 75C) und rhrte 20 h unter Rckfluss nach. Man lies auf Raumtemperatur kommen und filtrierte das Kristallisat ab. Der Filterkuchen wurde zweimal MIT JE 100 ML EINES 60 : 40 (V/V) -GEMISCHES AUS METHANOL/WASSER, einmal mit heiem Wasser (100 ml) und einmal mit Methanol (100 ml ; 25C) gewaschen und im Vakuumtrockenschrank bei +50C getrocknet. Auswaage : 23, 5 g Astaxanthin = 83, 0percent Ausbeute (bezogen auf eingesetztes Ia) ; Reinheit nach HPLC : 99, 17percentThe concentrated solution of Example 6 was added dropwise to a solution of triphenylphosphine (11.8 kg) and 1, 2-epoxybutane (130 g) in ethyl acetate (44 kg) at 0 to 30 ° C., and the reaction mixture was added dropwise at the same temperature And the mixture was stirred for 24 hours. The precipitated solid was collected by filtration and the wet crystals were dissolved in methylene chloride (39 kg). The obtained solution was added dropwise to ethyl acetate (305 kg) while stirring, and solid precipitation was confirmed. The precipitated solid was collected by filtration and dried in vacuo to give the title compound (3.95 kg, purity 87.5percent (trans form), 5.8percent (cis form)) as a white solid. The purity of the product was determined by high performance liquid chromatography (column: YMC-PAC ODS-A manufactured by YMC and mobile phase: acetonitrile with 0.1percent trifluoroacetic acid / 0.1percent aqueous trifluoroacetic acid = 5-95 / 45 to 5). 2, 7-dimethylocta-2, 4, 6-triene-1, 8-dialdehyde (0.484 kg), the compound of Example 7 (1) (3.90 kg), 2, 6-di-t-butyl-p-cresol (32.5 g) and 1, 2-epoxybutane (1.9 kg) were suspended in 2-propanol (15 kg) and the suspension was heated under reflux for 30 hours under a nitrogen atmosphere. The reaction mixture was cooled to -5 to 5 ° C. and stirred for 1 hour, and the precipitated solid was collected by filtration to give the title compound (1.53 kg, yield 86.9percent, purity 98.8percent, optical purity 97. 9percent ee) as a deep violet solid. The purity of the product was determined by high performance liquid chromatography (column: Triart C 18 ExRS Plus manufactured by YMC and mobile phase: acetonitrile with 0.025percent trifluoroacetic acid / 0.025percent aqueous trifluoroacetic acid = 30 to 98 / 2), respectively. The optical purity of the product was determined using high performance liquid chromatography (column: YMC CHIRAL Cellulose-SB manufactured by YMC and mobile phase: hexane / tetrahydrofuran = 85/15)
