Anti-Inflammatory and α-Glucosidase Inhibitory Triterpenoid with Diverse Carbon Skeletons from the Fruits of .

The fruits of Tratt. are edible nutritional food with high medicinal value and have been traditionally used as Chinese folk medicine for a long time. In this study, 26 triterpenoids including four new pentacyclic triterpenoids, roxbuterpenes A-D (, , , and ), along with 22 known analogues (, , -, , and ), were isolated from the fruits of .

Grevillosides R-S: glucosides of 5-alkylresorcinol derivatives from roots of (Thunb.) A. DC.

Grevillosides R-S (), two new glucosides of 5-alkylresorcinol derivatives, were isolated from the roots of (Thunb.) A. DC.

Terpenoids with Cytotoxic Activity from Roots of Ardisia crispa.

Three new terpenoids, ardisiacrispins G-I (1, 4 and 8), and eight known compounds, cyclamiretin A (2), psychotrianoside G (3), 3-hydroxy-β-damascone (5), megastigmane (6), corchoionol C (7), zingiberoside B (9), angelicoidenol (10), trans-linalool-3,6-oxide-β-D-glucopyranoside (11) were isolated from the roots of Ardisia crispa. The chemical structures of all isolated compounds were elucidated by extensive spectroscopic analyses, such as HR-ESI-MS, 1D and 2D NMR spectra. Ardisiacrispin G (1) represents the oleanolic-type scaffold featuring a rare 15,16- epoxy system.
