Phenolic compounds play an important role in defense system of the plants and animals against various fungal, bacterial and viral diseases. High performance liquid chromatographic (HPLC) analysis of the pulp of six varieties of Citrus fruits showed that they content good amount of phenolic acid. Lemon pulp (C. lemonum) had five phenolic acids viz., tannic, gallic, ferulic, o-coumaric and cinnamic acids in which gallic acid (32.18 μg/g) was maximum, followed by tannic (12.49 μg/g), ferulic (1.89 μg/g), o-coumeric (1.34 μg/g) and cinnamic (0.26 μg/g fresh wt) acids. Among other varieties having four phenolic acids, viz., tannic, gallic, ferulic and o-coumeric acids were detected. Juice from the pulps of citrus fruits are incorporated in daily dietary food, hence they might be playing a great role in imparting resistance to human body.
