Their structures were identified as 11-hydroxytabersonine (1) , venalstonid (2), sandine (3), oleanolic acid (4), ursolic acid (5), betulin (6) , (+)-pinoresinol (7), (-)-syringaresinol (8), 8-hydroxypinoresinol (9), (-)-latifolin (10) , cirsilineol (11) , loganin (12) , dibutylterephthalate (13) , and beta-sitosterol(14).
