[Retracted] Topical Treatment with Xiaozheng Zhitong Paste (XZP) Alleviates Bone Destruction and Bone Cancer Pain in a Rat Model of Prostate Cancer-Induced Bone Pain by Modulating the RANKL/RANK/OPG Signaling

Figure 1

HPLC analysis of the components of XZP. XZP were extracted with ethanol and the representative active components in the XZP extracts were characterized by HPLC using the standard components of (A) tetrahydropalmatine, (B) imperatorin, (C) isoimperatorin, (D) coptisine, and (E) palmatine chloride. Data are representative chromatographic histograms at 280 nm of XZP (a), characterized profile (UV chromatograms at 280 nm) of the standard compounds (a), XZP ethanol-extracts (b), and blank (c) from three independent experiments. (d) The structures of standard compounds.
