| Abstract: | Chemical investigation of the aerial part of Chonemorpha griffithii has led to the isolation of 20 compounds, comprising six lignans (1–6), six triterpenoids (7–12), four phenolic acids (13–16), two flavonoids (17 and 18), one cyclitol (19) and one aliphatic acid (20). Among them, 5′-methoxy-7′-oxomatairesinol (1) was identified to be a new lignan. It is the first report of the presence of those compounds in this genus. Two 24-methyl-29-norcycloartane triterpenoids (10 and 11) were considered as the chemotaxonomic markers for the species C. griffithii. |
