Macaranga denticulata is a 15‐18 m tall plant with rounded edges and long, rounded bark, 5 mm wide black covered with glands. In traditional medicine, this plant was used to treat fulminant hepatitis, dysentery, and urinary retention. In previous studies, we reported 13 isolated compounds from the fruits of Macaranga denticulata . This work presented the isolation and structural characterizations of seven compounds: 5‐(( E )‐3,5‐dihydroxystyryl)‐3‐(( E )‐3,7‐dimethylocta‐2,6‐dien‐1‐yl)benzen‐1,2‐diol ( 1 ), poilaneic acid ( 2 ), stigmast‐4‐en‐6 β ‐ol‐3‐one ( 3 ), epi‐taraxerol ( 4 ), rel ‐5‐(3 S ,8 S ‐dihydroxy‐1 R ,5 S ‐dimethyl‐7‐oxa‐6‐oxobicyclo[3,2,1]‐oct‐8‐yl)3‐methyl, 2 Z ,4 E ‐pentadienoic acid ( 5 ), ellagic acid 3,3'‐dimethyl ether‐4‐ O ‐ β‐ D ‐ glucopyranoside ( 6 ), 3‐hydroxypropanoic acid ( 7 ). The structures of the isolated compounds were elucidated from their mass and NMR spectral data.
