CHEMICAL CONSTITUENTS FROM THE LIVERWORT RICCARDIA NAGASAKIENSIS

Abstract

  The bisbibenzyls marchantin C and riccardin A along with the previously known eudesmane (+)-ent-selin-1 1-en-4β-ol were isolated from the liverwort Riccardia nagasakiensis. Phytol and the sesquiterpenoids β-elemene, longifolene, γ-cadinene and spathulenol were detected by GC-MS. Chemosystematics of some Riccardia species will be discussed.
