Abstract From the fruit coats of the medicinal plant Madhuca latifolia were isolated three new compounds, the triterpenoid madhucic acid (=3 β‐ (octanoyloxy)‐11‐oxoolean‐12‐en‐28‐oic acid; 1 ), the untypical isoflavone madhushazone (=9‐methoxy‐7‐(2,3,6‐trimethoxyphenyl)‐[1,3]dioxolo[4,5‐ g ][1]benzopyran‐8(8 H )‐one; 2 ), and a bis(isoflavone) named madhusalmone (=5,14‐dimethoxy‐3,12‐bis(3,4,5‐trimethoxyphenyl)‐1,6,8,10,15,17‐hexaoxanaphtho[2′,3′: 6,7]cyclodeca[1,2‐ b ]naphthalene‐4,13(4 H ,13 H )‐dione; 3 ), as well as eight known constituents, and their structures were elucidated by spectral analysis, including 2D‐NMR techniques.
