By the combinative method of fingerprint spectrums, the ultraviolet spectrum group draft of EGB761 was depicted. The established method is characteristic and reproducible and can be used in the identification and quality control of the medical materials, extracts and preparations. The ultraviolet spectrum group draft of EGB761 was tentatively depicted as: lambda max (nm): H2O solution (C = 0.02 mg/ml) 265.00 +/- 1.00, 201.00 +/- 1.00; EtOH solution (C = 0.02 mg/ml) 267.00 +/- 1.00, 210.00 +/- 1.00; CHCl3 solution (C = 0.4 mg/ml) 241.00 +/- 1.00; petroleum benzine solution (C = 0.4 mg/ml) 211.00 +/- 1.00.
