Three New Sesquiterpenoid Glucosides of Ficus pumila Fruit.
摘要:
As the glycosyl constituents of Ficus pumila L. fruits (Moraceae), three new sesquiterpenoid glucosides, pumilasides A, B and C were isolated together with benzyl β-D-glucopyranoside, (E)-2-methyl-2-butenyl β-D-glucopyranoside and rutin. Their structures were characterized as (1S, 4S, 5R, 6R, 7S, 10S)-1, 4, 6-trihydroxyeudesmane 6-O-β-D-glucopyranoside, (1S, 4S, 5S, 6R, 7R, 10S)-1, 4-dihydroxymaaliane 1-O-β-D-glucopyranoside and 10α, 11-dihydroxycadin-4-ene 11-O-β-D-glucopyranoside by spectral and chemical methods.
Six newhighlyoxygenated eudesmane sesquiterpenoid glucosides, senedensiscins A–F (1–6), were isolated from the aerial parts of Senecio densiserratus. Their structures with the absolute configurations were established on the basis of spectroscopic analyses and chemical methods. These compounds represent an unprecedented type of sesquiterpenoid glucoside with the angeloyl group directly connected to
