Internal standard method for detecting content of doped wild spina gleditsiae in spina gleditsiae decoction pieces

The invention discloses an internal standard method for detecting the content of wild spina gleditsiae doped in spina gleditsiae decoction pieces, and the adulteration amount X of the wild spina gleditsiae in the spina gleditsiae decoction pieces and the peak area Y of the wild spina gleditsiae component in the chromatogram of the spina gleditsiae decoction pieces have a quadratic function relationship and accord with the Lambert-Berr law. The method disclosed by the invention conforms to a scientific theory, the method is simple and convenient in experimental operation, can complete sample detection in a short time, can simply, quickly and accurately detect whether the spina gleditsiae decoction pieces are adulterated with wild spina gleditsiae or not and the adulteration proportion of the wild spina gleditsiae, provides a brand-new method for detecting adulteration of the traditional Chinese medicine decoction pieces, and provides a new visual field for quality control of the traditional Chinese medicine de
