In this study, the chemical compositional characteristic of citrus fruits sampled from the central part of India has been carried out. Sugars, organic acids and minerals have been estimated in citrus fruits. D-limonene was also studied in orange and sweet lime fruit rinds and juice using GC/MS. D-limonene content in rinds of orange fruits ranged between 13.72 to 34.55 g kg−1and in lime fruits between 17.33 to 38.71 g kg−1. The ratio of citric acid to isocitric acid ranged between 78.9 to 129 confirming the authenticity of fruit juices. Minerals such as Ca and P were also analyzed using ICP-AES. Ca/P ratio is useful for studying the nutritional requirements of the fruit juices. A probable mechanism of D-Limonene formation in fruits is also discussed.
