Abstract
Three new sulfated triterpene glycosides, asprellanosides C-E (1-3), were isolated from the roots of Ilex asprella. Their structures were elucidated as 3β-[(2-O-sulfo-β-d-xylopyranosyl)oxy]urs-12,19(29)-diene-28-oic acid 28-β-d-glucopyranoside (1), 3β-[(2-O-sulfo-β-d-xylopyranosyl)oxy]urs-12,19-diene-28-oic acid 28-β-d-glucopyranoside (2), and 3β-[(2-O-sulfo-β-d-xylopyranosyl)oxy]urs-12,19-diene-28-oic acid (3) on the basis of the spectral and chemical methods.
