The graphite furnace–atomic absorption spectrometry determined the presence of sodium (6.38 ppm), potassium (701.93 ppm), calcium (371.28 ppm), magnesium (54.78 ppm), cadmium (0.013 ppm), zinc (0.256 ppm) and lead (0.200 ppm). The content of peel, moisture and ash of C. macrophylla was measured as 18.35%, 23.75% and 2.04%, respectively. Among thirty compounds identified using gas chromatography–mass spectrometry, limonene is the major compound (72.85%). The vitamin C (ascorbic acid) content of C. macrophylla juice was determined as 55.0 mg/100 g. The fruit diameter, fruit weight and percentages of juice, peel and seed were determined as 91.4 mm, 276.5 g, 47.92%, 26.37% and 19.20%, res...
