概要
- 論文の詳細を見る
From a MeOH extract of the leaves of Clethra barbinervis Sieb. et Zucc., ryobunins A–C, three new triterpene glucosides, i.e. one ursane, one seco-ursane and one oleanane-type glucoside, along with four known compounds were isolated. Their structures were elucidated based on chemical and spectral evidence.
