The title compound, C20H18N2O4, is a chalcone derivative of pyrazole. The pyrazole ring is inclined at a dihedral angle of 19.29 (12)° to the methoxy­phenyl ring mean plane, and by 1.19 (13)° to the phenyl ring. The mol­ecular structure is stabilized by an intra­molecular O—H⋯O hydrogen bond, making an almost planar (r.m.s. deviation = 0.0243 Å) six membered ring.

A lipoxygenase inhibiting triterpene have been isolated for the first time from the ethyl acetate soluble fraction of whole plant of Solanum surrattense and the structure was assigned on the basis of 1D (1 H NMR, 13 C NMR, DEPT, NOE) and 2D NMR (HMBC, HMQC, COSY, NOESY) experiments. The biological potential of the isolated compound was performed against lipoxygenase enzyme using baicalein as a positive control.
