Identification of Vitamins and antioxidant in Carrot by HPLC

Vitamins and antioxidant were important Component for carrot . HPLC analysis proved that in carrot contains Soluble Vitamins (184.74 mg/ml Vita C,. 3394.08mg/ml Vita.B3,147.675 Vita.B2,12.918Vita.B6,21.903Vita.B1) and (34.481mg/ml Vita.A,652,488 Vita .E)and many types of antioxidant (56.005 mg/ml Carotine,580.380 Carotine,299.890 mg/ml lutein) Key word: carrot ,antioxidant INTRODUCTION Carrot is a good source of vitamins (A,B,C) and contains folic acid and trice element (K, Na ,Mg ,P , S, MN ,Fe ,Cu ) and Zn (1). vegetables are sources of health-promoting active in neutralization of reactive oxygen species(2)among them carrot has nutritional value and high concentration of bioactive constituents(3). Carrot is important root vegetables rich in carotenoids and dietary fibers with functional components including phenolic compound(4) and their antioxidant capacity have been determined(5). the presence of phenolic compounds in Carrot contributes to their sensory qualities ,like colours(6,7.8). There is two types of antioxidant lipophilic (carotenoids) and hydrophilic (phenolic compounds)characters (9,10,11). The presence of phytochemicals and vitamins in Carrot has been recently considered of crucial nutritional Importance in the prevention of chronic diseases ,such as cancer , cardiovascular diseases and diabetes (12,13,14) MATERIAL AND METHOD Plant material The plant Carrot was collected from Tikrit city ,salahaldin . the root were washed with distilled water ,sample preparation is similar to the preparation of medicinal herbs. Fresh carrots were sliced by BRAUN blender (Germany) and dried at +40 c Methods Analysis of soluble vitamins in carrot The main compound were separated on FLC (Fast liquid chromatographic)column under the optimum condition Mobile phase: (A)0.01M potassium phosphate pH 2.6:5Mm octane Sulphonate (ion-pair) (B) acetonitrile , A:B (9:1,V/V) detection UV set at 270nm, Flow rate 1.5ml /min . six stander solutions25mg/ml were used Analysis of vit A and E in carrot Mobile phase: nhexane :isopropanol , (99:1.0, v/v) Flow rate 1.2 ml/min. two stander solution 25mg/ml were used Analysis of antioxidant Column:C-18(50*20mm) Mobile phase acetic acid ,methanol Flow rate 1ml/min . four stander solution 25mg/ml were used. All the chromatographic analysis done by HPLC( Shimadzu ,JAPAN) . The concentration of identified compound was calculated to the equation(15,16) Conc. Of sample(mg/ml)=Area of sample/Area of stand. *C*D C=Conc.of standard solution D=Dilution factor RESULTS AND DISCUSSION The HPLC analysis of soluble vitamins in the carrot showed five peaks fig.(1) with different Rt (1.958,3.137,4.193,4.957,7.008) min. and area for each peak were (47453,85273,33927,3641,5122) showed in table(1) Table1:Retention Times and Area under curves for soluble vitamins Rt.

HPLC analysis of vitaA and E showed 2 peaks fig.(3) with different Rt (1.84,3.848) min. and the area for each peak were (114945,188898) Table (3). Ilham Nazhan Numan et al /J. Pharm. Sci. & Res.
