RESUMO
Objective:To investigate constituents containing phenolic hydroxyl or carboxylic acid (excluding diarylheptanoids) from Curcumae Rhizoma and Sparganii Rhizoma herbal pair and single herb. Method:Multiple chromatographic separation techniques, including silica gel,MCI gel and Sephadex LH-20 gel, were employed to isolate and purify the compounds. Their structures were identified by means of the nuclear magnetic resonance (NMR),mass spectrometry (MS) and physicochemical properties. Constituents were quickly analyzed by UPLC-LTQ-Orbitrap-MSn,and scanned in positive and negative ion modes. Result:These compounds were determined as trans-p-hydroxycinnamic acid(1),vanillic acid(2),protocatechuic acid(3),fumalic acid(4),succinic acid(5),succinic acid monomethyl ester(6),docosanoic acid(7),azelaic acid(8) and p-hydroxybenzaldehyde(9). Forty compounds were speculated by comparing mass spectrometry data,retention times of some compounds and reference materials,including 14 phenols and 26 organic acids. Among the compounds of herbal pair,8 phenols and 22 organic acids in Sparganii Rhizoma as well as 11 phenols and 13 organic acids in Curcumae Rhizoma were identified. Cleavage pathways of main compounds were described. Conclusion:There are abundant phenols and organic acids in Curcumae Rhizoma and Sparganii Rhizoma herbal pair and single herb. The results enrich pharmacodynamic material basis of Curcumae Rhizoma and Sparganii Rhizoma herbal pair.
RESUMO
<p><b>OBJECTIVE</b>To explore the effect of ligustrazine on the migration of bone marrow mesenchymal stem cells (BMSCs) and protein expressions of matrix metalloproteinase-2 and-9 (MMP-2 and MMP-9) in vitro.</p><p><b>METHODS</b>BMSCs were in vitro isolated and cultured using whole bone marrow adherent method, and phenotypes [surface positive antigens (CD29 and CD90) and negative antigens (CD34 and CD45)] identified using flow cytometry. BMSCs were divided into the blank control group, 25, 50, 100 µmol/L ligustrazine group, and the GM6001 group (100 µmol/L ligustrazine +MMPs inhibitor GM6001 ). The migration of BMSCs was tested by Transwell chamber test and wound healing assay after treated with ligustrazine for 24 h. The protein expressions of MMP-2 and MMP-9 were detected by Western blot.</p><p><b>RESULTS</b>The third passage BMSCs grew well in uniform morphology. The expression rate of CD29, CD90, CD34, and CD45 was 96.9%, 97.3%, 0.2%, and 3.0%, respectively. Compared with the blank control group, the number of migrated cells and relative distance of cell invasion increased, and the protein expressions of MMP-2 and MMP-9 were elevated in each ligustrazine group (P < 0.05, P < 0.01). Compared with 100 µmol/L ligustrazine group, the number of migrated cells and relative distance of cell invasion decreased in 25 and 50 µmol/L ligustrazine groups and the GM6001 group (P < 0.01). Protein expression of MMP-2 decreased in 25 and 50 µmol/L ligustrazine groups (P < 0.01).</p><p><b>CONCLUSION</b>Ligustrazine could promote the migration of BMSCs in vitro, and its mechanism might be related to up-regulating expression levels of MMP-2 and MMP-9 protein.</p>
