The Onchidium genus (Mollusca, Gastropoda, Pulmonata, Systellommatophora, Onchidiidae family) is used as the important economical shellfish, due to the high nutritional value and medicinal value. Research over the previous decades indicated that Onchidium sp. mainly contains polypropionates, depsipeptides, terpenoids and other chemical components. Many biological activities of Onchidium (e. g., cytotoxic activities against tumor cells, anti-viral and anti-bacterial activities) have been reported. This review reports a total of 60 compounds, synthetic work and biological studies on Onchidium genus, covering the literature from 1978 to date, with a view to providing a reference and helping for the in-depth research of this genus.
Keywords: Onchidium genus; biological activity; natural products; polypropionates; secondary metabolites.
