Rosanortriterpenes A-B, two new nortriterpenes from the fruits of var. .

One new oleanane-type nortriterpene, rosanortriterpene A (), and one new ursane-type nortriterpene, rosanortriterpene B (), were isolated from the fruits of var. . The structures of - were fully characterised on the basis of extensive spectroscopic analysis, including IR, HRESIMS, as well as 1D and 2D NMR spectral data (HSQC, H-H COSY, and HMBC).
