  • 摘要:

    Two new triterpenoid saponins, latifoloside I (1), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl 3β, 21α, 28-trihydroxy-urs-12-ene 21-O-β-D-glucopyranoside; latifoloside J (2), 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-3β, 21α-dihydroxy-ursolic acid 21-O-β-D-glucopyranoside, along with two known compounds, latifoloside C (3) and latifoloside E (4), were isolated from the bark of Ilex latifolia THUNB. Structure assignments were established on the basis of spectroscopic data and chemical evidence.
