title: A new anti-HBeAg lignan, kadsumarin A, from Kadsura matsudai and Schizandra arisanensis.
abstract: A new C18 dibenzocyclooctadiene lignan, kadsumarin A (1) was isolated from Kadsura matsudai Hayata and Schizandra arisanensis Hayata. The anti-HBeAg test revealed that kadsumarin A had activity at a concentration of 40 micrograms/ml (= 90.1 microM). Its structural elucidation by spectral analysis was discussed in this note.
