Abstract:
Objective:The HPLC fingerprinting of Swertia mussotii was established to study the correlation between chemical components and ecological factors in different areas. Method:The fingerprint of S. mussotii was established by high performance liquid chromatography (HPLC),and the evaluation and analysis were made based on the " Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System 2004A Edition" promulgated by the National Pharmacopoeia Commission. The analysis was carried out on a Wondasil C18 column(4.6 mm×250 mm,5 μm), with methanol-0.2%phosphoric acid as the mobile phase for gradient elution,and the column temperature was set at 30℃. The flow rate was 1.0 mL·min-1, and the detection wavelength was set at 245 nm. And data on ecological factors in each sample habitat, such as climate and soil, were collected. The gray correlation and bivariate analysis were carried out on the chemical constituents and ecological factors of medicinal materials in different areas using DPS data processing system and SPSS 21.0 statistical software. Result:The HPLC fingerprint of S. mussotii was established,a total of 12 common fingerprint peaks were marked, and the chemical constituent of the seven peaks were determined. The chemical constituents, such as swertiamain and mangiferin of S. mussotii, were significantly correlated with ecological factors. Moreover,the chemical constituents were obviously affected by the monthly average temperature range,annual precipitation,precipitation seasonality in the climatic factors,the soil organic carbon ratio and soil pH in the soil factors. Conclusion:The chemical constituents of S. mussotii have a correlation with the external ecological factors,the findings could provide a basis for the artificial planting of the medicinal material and the scientific connotation of the " environment-based" theory for Tibetan medicines.
