Chemical Constituents from the Fruits of Madhuca latifolia

From the fruit coats of the medicinal plant Madhuca latifolia were isolated three new compounds, the triterpenoid madhucic acid (=3β‐(octanoyloxy)‐11‐oxoolean‐12‐en‐28‐oic acid; 1 ), the untypical isoflavone madhushazone (=9‐methoxy‐7‐(2,3,6‐trimethoxyphenyl)‐1,3]dioxolo4,5‐g]1]benzopyran‐8(8H)‐one; 2 ), and a bis(isoflavone) named madhusalmone (=5,14‐dimethoxy‐3,12‐bis(3,4,5‐trimethoxyphenyl)‐1,6,8,10,15,17‐hexaoxanaphtho2′,3′: 6,7]cyclodeca1,2‐b]naphthalene‐4,13(4H,13H)‐dione; 3 ), as well as eight known constituents, and their structures were elucidated by spectral analysis, including 2D‐NMR techniques.
