N2 - A new hexacyclic alkaloid, chilocorine C (4), has been isolated from Chilocorus cacti and. characterized on the basis of its IR, UV, MS, and NMR data. Although its structure is closely related to that of exochomine (1) (isolated from Exochomus quadripustulatus) and to chilocorine A (2) and B (3) (obtained previously from C. cacti), the presence of a hydroxymethyl substituent on the saturated tricyclic moiety represents an unexpected structural variation on the dimeric alkaloid theme.
