ABSTRACT
Phytochemical investigation on an EtOH extract of the leaves of Mons yunnanensis led to the isolation and characterization of 11 isoprenylated phenolic compounds, morusyunnansin G (1), morachalcone B (2), cudraxanthone M (3), cudraxanthone D (4), sanggenofuran B(5), moracin D (6), moracin C (7), moracin I (8), demethylmoracin I (9), morachalcone A (10), and isobacachalcone (11). Compound 1 is a new compound and compounds 2-11 were isolated from this plant for the first time.

Three new isoprenylated flavones, hypargyflavones A-C (1-3, resp.), and one novel stilbene derivative, hypargystilbene A (4), together with seven known compounds, 5-11, were isolated from the stems of Artocarpus hypargyreus Hance. The structures were elucidated by spectroscopic methods. Hypargyflavone A (1), cudraflavone C (8), brosimone I (10), and norartocarpin (11) showed inhibitory effects on pancreatic lipase.
