Changes

All parts of the plants of citrus sp. contain coumarins and psoralins. The fruits contain flavonoids and limonoids. The flavonoids comprise three main groups—flavanones, flavones and 3-hydroxyflavylium (anthocyanins); flavanones being predominantly followed by flavones and anthocyanins. Bitter flavonoids do not occur in lemon and lime. Lemon juice is a richer source of antiscorbutic vitamin (contains 40–50 mg/100 g of vitamin C) than lime, and a fair source of carotene and vitamin B. Volatile oil (about 2.5% of the peel) consists of about 75% limonene, alpha-and beta-pinenes, alpha-terpinene and citral. The fruit juice also contains coumarins and bioflavonoids.<ref name="chemical composition"/>
