Recognition of Radix Paeoiae Alba Herbs(Fam. Ranunculaceae) with HPLC Fingerprint Spectra

Abstract

The relative-area difference sequence (ΔSr sequence) analytical method is proposed, with which the most similar herbal samples can be determined according to their contents. Together with common and variation peak ratio dual-index sequence analysis, one can identify the most similar sample group in the two-dimensional sequence accurately; therefore, the method can evaluate the quality of herbs.
