title: A new triterpenoid and a new glycoside from Pilea cavaleriei.
abstract: A new triterpenoid, 11α,12α-epoxy-3β-hydroxy-24-nor-olean-4(23)-en-28,13β-olide (1), and a new glycoside, benzyl 2-O-β-d-apiofuranosyl-(1 → 2)-β-d-glucopyranosyl benzoate (2), together with eight known triterpenoids (3-10), were isolated from Pilea cavaleriei subsp. cavaleriei. Their structures were established on the basis of spectroscopic analysis including HR-ESI-MS, 1D NMR, and 2D NMR techniques. All compounds showed no anti-hepatitis C virus activity.
