From the root tuber of Stephania cepharantha HAYATA (Japanese name "Tamasaki-tsuzurafuji") cultivated in Japan, cepharanthine (I), isotetrandrine (II), cycleanine (III), and berbamine (IV) were isolated together with a new crypto-phenolic base of bisbenzylisoquinoline type, cepharanoline (decomp. 270°, [α]^<35>_D +319° (CHCl_3), C_<36>H_<36>O_6N_2). The O-methylcepharanoline (mp 103°, [α]^<30>_D +287° (CHCl_3), C_<37>H_<38>O_6N_2) was identified by comparison with cepharanthine (I). The mass spectrum of cepharanoline revealed that the phenolic hydroxyl in cepharanoline is present in 4'-position. These experiments revealed that cepharanoline is represented by formula VII.
