Abstract: The twigs and leaves of Pithecellobium clypearia (Jack.) Benth are used as common Chinese traditional herbal medicine to treat upper respiratory tract infection, acute gastroenteritis and bacterial dysentery. The study isolated nine compounds from the EtOAc extract, all of which were obtained from Pithecellobium Mart. for the first time. Based on 1 H-NMR and 13C-NMR data, the structures of these compounds, including two ladiosiplodins and two dihydroisocoumarins, were elucidated.

Key words: Pithecellobium clypearia (Jack.) Benth, ladiosiplodins, dihydroisocoumarins
