Capoamycin-type antibiotics (2-5) and polyene acids (6, 7) were isolated from marine Streptomyces fradiae strain PTZ0025. Their structures were established by extensive nuclear magnetic resonance (NMR) and high resolution electron spray ionization mass spectroscopy (HRESIMS) analyses and chemical degradation. Compounds 3, 4, 6, 7 were found to be new and(More)
A novel baccharane-type triterpenoid glycoside named fatsioside A (1), together with ten oleanane glycosides, were isolated from the fruits of Fatsia japonica. The structure of fatsioside A was assigned as 3β,15α,18α-trihydroxy-18,19-secolupane-12,19-dione 3-O-β-D-glucopyranosyl-(1 → 2)-β-D-glucopyranoside by extensive NMR and HRESIMS analyses.
