Quantitation of minerals iron and calcium from vegetables, for example, spinach and vegetables Cantonese coccinia grandis by means of Atomic Absorption Spectrophotometry analysis of whether the quantity of iron minerals found in fruits and vegetables, there is a maximum quantity of 196 coccinia grandis.10 mg/kg on a mg/kg and spinach vegetable 147.49 Guangdong 111.53 mg/kg best vegetables that have the most calcium are vegetables, Cantonese with calcium is 11319.46 mg/kg up to a spinach 1294.67 mg/kg and vegetable calcium cannot be found in finding coccinia Indica performance analysis of threshold values by the lowest concentration that can be detected (LOD) and the lower threshold value in quantity (LOQ) of iron is equal to 1 and 0.4423.4741 ppm of calcium is equal to 0.6357 and 2.1155 ppm, respectively. To find the percent return of iron is equal to 99.96% of calcium is equal to 99.44%, which is the accepted benchmark.
