One new indole alkaloid (1), together with a known indole alkaloid (2), one triterpene (3) and two sterols (4-5), were isolated from the fruits of Capparis masaikai (Capparceae). Their structures were identified on the basis of their MS, 1D NMR and 2D NMR spectra and by comparison of their data with those reported previously in the related literatures. To our best of knowledge the compounds 1-5 were isolated from this plant material for the first time.
