Vitamin C (VC), known as L-ascorbic acid, is an essential nutritive component of the human diet that must be derived from vegetable, fruit, and food crops. Hence, VC is an important analyte in many agricultural products and their processing products. Moreover, the importance of VC in various physiological and biochemical fields of crops has extensively been reviewed elsewhere [1–5]. VC is an irreplaceable cofactor in several pathways, including the xanthophyll cycle; synthesis of hormones, hydroxyproline-rich proteins, and important cell wall components [5]. VC also plays a number of important roles in physiological and biochemical analysis of crops [4,6,7] such as the regulation of cell division, flowering
