A new rearranged clerodane diterpenoid, tinocrispide was isolated from the stems of Tinospora crispa along with thirteen known compounds including eight clerodane diterpenoids. Among the known compounds baenzigeride A, (6S, 9 R)-vomifoliol and steponine are being reported for the first time from T. crispa. Their structures were elucidated by 1 D and 2 D NMR and confirmed by HRESIMS. The 13C NMR data of borapetol A has been revised.
