- 論文の詳細を見る
A new tetrahydroxy triterpene acid, named clethric acid (I), in addition to barbinervicand rotundic-acids, has been isolated from the leaves of Clethra barbinervis SIEB. et ZUCC and clethric acid was elucidated as 3α, 19α, 23,24-tetrahydroxyurs-12-en-28-oic acid by the chemical and spectral evidences. The ^<13>C-nuclear magnetic resonance spectra of the methylates and acetyl methylates of clethric acid, pomolic acid, rotundic acid and barbinervic acid were studied.
