Boi and its original plant Sinomenium acutum from Japan were compared with Seifuto and its botanical origins from China in terms of their internal transcribed spacer (ITS) sequences and major chemical components. Boi, Seifuto, and their botanical origins overall showed seven variable sites in the ITS sequence and six genotypes. Japanese S. acutum and Boi had one nucleotide variation at position 593 to show two genotypes (J1 and J2) and their heterozygote (J3). Seifuto samples and their botanical origins, S. acutum and S. acutum var. cinereum from China, showed three genotypes (C1, C2, and C3), which did not agree with the botanical classification, indicating that they cannot be distinguished according to their ITS sequences. All Seifuto samples from Henan market showed the same ITS genotype (C1). The Japanese and Chinese genotypes differed in the nucleotide position 424, which can be used to distinguish the country of origin of these materials. In the HPLC analysis of six major components, sinomenine (1), magnoflorine (2), menisperine (3), 6-O-methyllaudanosoline glucoside (4), liriodendrin (5), and menisdaurin (6), all were detected in Boi, whereas five (all except for menisdaurin) were detected in Seifuto. The main component in the rhizome of Seifuto was sinomenine, whereas magnoflorine was the main component in the rhizome and the climbing stem of Boi. The content of sinomenine in Seifuto was almost twice that in Boi. Although the individual content of alkaloids 1-4 differed between Boi and Seifuto, the total contents of these alkaloids were comparable between them both in the climbing stem and rhizome.
