Patent ID: 8428883

Claim:
A computer implemented method for evaluation of a multi-component medicine comprising: providing a programmed processor that performs the following: (1) obtaining chromatographic high performance liquid chromatography fingerprint data of three-dimensional high performance liquid chromatography of the multi-component medicine to be evaluated, (2) combining the chromatographic high performance liquid chromatography fingerprint data obtained in (1) with chromatographic high performance liquid chromatography fingerprint data of three-dimensional high performance liquid chromatography of other multi-component medicines of the same kind forming a chromatographic high performance liquid chromatography fingerprint data reference group, (3) allocating variable axes to the number of multi-component medicine and the elution time or detection wavelength of the chromatographic high performance liquid chromatography fingerprint data reference group of (2) above and regarding a signal strength as a characteristic amount, (4) obtaining a unit space from the characteristic amount of (3), and (5) obtaining the Mahalanobis distance of the multi-component medicine to be evaluated from the unit space obtained in (4).
