Four lignans and six kauranes, (+)‐ epi ‐syringaresinol ( 1 ), annocherin A (16β‐hydroxy‐17,19‐diacetoxy‐ ent ‐kaurane) ( 2 ), (+)‐syringaresinol ( 3 ), (+)‐ dia ‐syringaresinol ( 4 ), liriodendrin[(+)‐syringaresinol‐di‐ O ‐β‐ D ‐glucopyranoside] ( 5 ), 16α‐hydro‐17‐acetoxy‐ ent ‐kauran‐19‐oic acid ( 6 ), 16β‐hydro‐17‐hydroxy‐ ent ‐kauran‐19‐al ( 7 ), 16α‐hydro‐17‐hydroxy‐ ent ‐kauran‐19‐al ( 8 ), 16β‐hydro‐17‐hydroxy‐ ent ‐kauran‐19‐oic acid ( 9 ) and 16α‐hydro‐17‐hydroxy‐ ent ‐kauran‐19‐oic acid ( 10 ) were isolated from the stems of Annona cherimola. Among them, 1 is obtained for the first time from natural sources and 2 is a new compound. The structures of these compounds were characterized and identified by spectral analyses.
