Hesperidin is a natural occurring flavanone glycoside present in citrus fruits that exhibits antioxidant, neuroprotective, and antiinflammatory activities. Rodrigues, in Studies in Natural Products Chemistry, 2018 Hesperidin For example, in the Solanum lycopersicum peel, the level of chalcone synthesis and flavanone 3-hydroxylase gene expression is higher than the chalcone isomer, indicating the accumulation of the high amount of naringenin. Distribution of naringenin in different parts of fruit depends on the concentrations of biosynthesis enzymes. Naringenin is found as “Naringin” which is an inactive form and converted into “Naringenin” by intestinal bacteria. The skin of tomato contains Naringenin-chalcone, converted to Naringenin during ketchup making process. Naringenin was initially reported to be isolated from celery seeds, grapefruit leaves. Naringin (Naringenin-7-neohesperidoside) is the main flavonoids found in grapefruits, oranges, and low amount of naringenin are found in tomatoes as well.

The solid tissues possess the highest concentration, whereas juice contains a fair amount of flavanones as well.

Primarily the source of flavonoids to human was dietary intake and these are present in nearly all citrus fruits but the concentration is different depending on the type and variety of the fruit, time of harvesting and environmental condition, e.g., Citrus aurantium (19.7 μg/mL) Citrus reticulata (3383.6 μg/mL) Citrus clementina (8.0 μg/mL) Citrus bergamia (22.3 μg/mL) Citrus paradisi (230.0 μg/mL). In smaller quantities it is also found in bergamot, cocoa, water mint, Drynaria, as well as in beans. Naringenin is present in citrus fruits like grapefruits (115–384 mg/L), sour orange (> 100 mg/L), tart cherries, tomatoes (0.68 ± 0.16 mg/100 g), Greek oregano.
