Four new dammarane-type triterpene saponins named floranotoginsenosides A (1), B (2), C (3) and D (4), together with five known triterpene saponins, were isolated from the flowers of Panax notoginseng. Their structures were elucidated on the basis of spectral and chemical evidence.

BACKGROUND Platycodon grandiflorum is the only species in the genus Platycodon of the family Campanulaceae, which has been traditionally used as a medicinal plant for its lung-heat-clearing, antitussive, and expectorant properties in China, Japanese, and Korean. Oleanane-type triterpenoid saponins were the main chemical components of P. grandiflorum and platycodin D was the abundant and main bi...

In this research, aerial parts of Euphorbia denticulata Lam were collected from Sanandaj city in Kurdistan province at the West of Iran. It was extracted by maceration using acetone as solvent. Isolation of compounds were carried out with repeated column chromatography using silica gel and normal preparative HPLC using YMC-Pack-Sil column and hexane: ethyl acetate as mobile phase. The structure...

Five new oleanane-type saponins, named ligushicosides A-E, and three known oleanane-type saponins were isolated from the roots of Ligulariopsis shichuana. Their structures were established by a combination of spectroscopic techniques, including 1D and 2D NMR and high resolution electrospray ionization mass spectroscopy (HR-ESI-MS). Furthermore, all isolates were evaluated for their yeast α-gluc...

Saponins are a structurally diverse class of compounds occurring in many plant species, which are characterized by a skeleton derived of the 30-carbon precursor oxidosqualene to which glycosyl residues are attached. Traditionally, they are subdivided into triterpenoid and steroid glycosides, or into triterpenoid, spirostanol, and furostanol saponins. In this study, the structures of saponins ar...

Seven new dammarane-type triterpenoid saponins, chikusetsusaponin FK1 (1), chikusetsusaponin FK2 (2), chikusetsusaponin FK3 (3), chikusetsusaponin FK4 (4), chikusetsusaponin FK5 (5), chikusetsusaponin FK6 (6), and chikusetsusaponin FK7 (7), and eleven known triterpenoid saponins, ginsenoside Rb3 (9), ginsenoside Rc (10), chikusetsusaponin VI (11), ginsenoside Re (12), ginsenoside Rg1 (13), pseu...
