Abstract:
A new taraxer-based triterpenoid ester, taraxer-14-en-30-al-3β-O-palmitate(1), was isolated from the whole plant of Wedelia trilobata, along with six known compounds, ent-kaur-16-en-19-oic acid(2), 16α-hydroxy-ent-kauran-19-oic acid(3), tara-xerol(4), β-amyrin(5), 1β-acetoxy-4α, 9α-dihydroxy-6β-isobutyroxyprostatolide(6), and stigmasterol(7). Their structures were elucidated with use of a combination of spectroscopic techniques(IR, HR-ESI-MS, 1 D, 2 D NMR data) and chemical methods.
