Abstract:
A new triterpenoid ester, 7β-hydroxyl-hop-22(29)-en-3β-O-palmitate (1), was isolated from the stems and leaves of Scurrula parasitica parasitic on Nerium indicum, along with nine known compounds, uvaol (2), 3-epi-ursolic acid (3), 3β-hydroxyl-hop-22(29)-ene (4), 3β, 15α-dihydroxyl-lup-20(29)-ene (5), lup-20(29)-en-3-O-α-D-glucoside (6), stigmasterol-3-O-β-D-glucoside (7), digitoxin-3-O-α-D-glucoside (8), behenic acid (9), octacosyl alcohol (10). Their structures were elucidated using a combination of 1D and 2D NMR techniques (COSY, HMQC, and HMBC) and HR-ESI-MS analyses. Compounds 2-10 were isolated from this plant for the first time.
