title: Triterpenoids from Viburnum betulifolium.
abstract: Two new triterpenoids, ursa-12-sene-3β,11β-diol 3-O-palmitate (1) and ursa-12-sene-1β,3β,11α-triol 3-O-palmitate (2), were isolated from the 70% aqueous acetone extract of the aerial parts of Viburnum betulifolium, together with the artificial diene derivative of 2, ursa-12-dien-1β,3β-diol 3-O-palmitate (2a). Their structures were characterized by various spectroscopic methods, including 1D NMR, 2D NMR, and HR-ESI-MS.
