Ceriops decandra is a mangrove tree species, reputed for its folkloric uses in the treatment of gastrointestinal disorders, infection, snakebites, inflammation, and cancer. Different parts of the plant are rich with various phytoconstituents which include diterpenoids (ceriopsin A-G), triterpenoids (lupeol, α-amyrin, oleanolic acid, ursolic acid), and phenolics (catechin, procyanidins).These phytoconstituents and their derivatives could form a new basis for developing new drugs against various diseases. The objective of the present study is to compile the phytochemical, ethnobotanical, biological, and pharmacological significance of the plant to provide directions for future research to find out therapeutically active lead compounds for developing new drugs against diseases of current interest including diabetes, inflammation, and cancer.
