Protein-Based Fingerprint Analysis for the Identification of Ranae Oviductus Using RP-HPLC [PDF]

open access: yesMolecules, 2019
This work demonstrated a method combining reversed-phase high-performance liquid chromatography (RP-HPLC) with chemometrics analysis to identify the authenticity of Ranae Oviductus. The fingerprint chromatograms of the Ranae Oviductus protein were established through an Agilent Zorbax 300SB-C8 column and diode array detection at 215 nm, using 0.085 ...
