  • In this study, we developed and validated the HPLC method using the isolated components from Erycibae caulis. Their structures were elucidated by spectroscopic methods including UV, $^1H$-NMR, $^{13}C$-NMR, FAB-Mass and ESI-Mass as Compound 1 (crypto-chlorogenic acid), Compound 2 (scopolin), Compound 3 (neochlorogenic acid) and Compound 4 (3,4-di-O-caffeoylquinic acid). Major three compounds and scopoletin were decided as representative components of Erycibae caulis. We established HPLC analytical method by using the representative components and 20 commercial samples which were collected considering to various cultivated area. The HPLC fingerprinting was successfully achieved with an AKZO NOBEL Kromasil 100-5C18 column. The mobile phase consisted of 0.5% acetic acid in water (A) and methanol (B) using gradient method of 85(A) to 50(A) for 35min. The fingerprints of chromatograms were recorded at an optimized wavelength of 330 nm. This developed analytical method was validated with specificity, selectivity, accuracy and precision. And it is suggested that scopolin, scopoletin, neochlorogenic acid, 3,4-di-O-caffeoylquinic acid were more than 0.162%, 0.133%, 0.057%, 0.044%, respectively. In addition, principal component analysis (PCA) was performed on the analytical data of 20 different Erycibae caulis samples in order to classify samples collected from different regions. We hope that this assay can be readily utilized as quality control method for Erycibae caulis.

  • Objectives : The aim of the present study is to examine the effect and mechanism of Erycibae Caulis and Corydalis Tuber Pharmacopuncture (ECP) on a mouse model with collagen induced rheumatoid arthritis (CIA). Methods : We evaluated the Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Creatinine, and the Blood urea nitrogen (BUN) of serum to examine the safety of this study. In vivo, we compared the results of the non-treated group, the normal saline pharmacopuncture treated control group, the indomethacin treated group and the ECP group. We evaluated rheumatoid arthritis manifestation and the Rheumatoid Arthritis Index (AI). Also, immune cells in blood affected by ECP were evaluated by calculating the level of white blood cells (WBC), neutrophil, lympocytes and monocytes. Next, the level of Immunoglobulin M (IgM), Immunoglobulin G (IgG), Interleukin (IL)-$1{\beta}$, IL-6, IL-17, Tumor Necrosis Factor (TNF)-${\alpha}$ and Granulocyte-macrophage Stimulating Factor (GM-CSF)in serum were measured. We examined the imaging of cartilage degeneration using micro CT-arthrography of the hind paw. Additionally, we examined the effects of reducing bone volume (BV) ratio and bone surface/bone volume (BS/BV) ratio with 3D Micro-CT. Finally, we did a histopathologic examination analysis. Results : The absence of liver and kidney toxicity was evident. In vivo, edema of the joints of the ECP group decreased greatly in macroscopic observation. AI measurement of the ECP group also decreased significantly compared to the control group. The level of WBC, neutrophil, lympocytes, and monocytes in the blood decreased but there was no statistical significance of this data. IgM of the ECP group decreased significantly compared to the control group. IL-$1{\beta}$, IL-6, TNF-${\alpha}$, and GM-CSF production of the ECP group decreased significantly compared to the control group. As a result of examining joint condition with 3D micro CT, deformation and destruction of the joint was shown to have decreased. Bone density of ECP group increased at a statistically significant level compared to the control group. Degree of joint inflammation of ECP group decreased significantly compared to the control group. After H&E and M-T staining, infiltration of immune cells, subsidence of the cartilage, damage to the synovial cells and joint erosion decreased. Conclusion : This study showed that ECP hindered the process of rheumatoid arthritis and protected joints and cartilage.
