Abstract:
Objective:To study the correlation of eight chemical components in Miao medicine Periploca forrestii from different producing areas with the ecological and soil factors. Method:The contents of neochlorogenic acid， chlorogenic acid， cryptochlorogenic acid， isochlorogenic acid B， isochlorogenic acid A， isochlorogenic acid C， procyanidin A2， and periplocin were simultaneously determined by ultra-performance liquid chromatography （UPLC）. The root soil samples from various producing areas were collected for testing various soil factors， followed by climate data extraction with ArcGIS and topographic data recording using GPS. SPSS 24.0 was employed to conduct the bivariate analysis and stepwise regression analysis of the eight chemical components in P. forrestii from different producing areas with the ecological and soil factors. Result:Stepwise regression equations of the content of eight chemical components against ecological and soil factors were established. The findings demonstrated that neochlorogenic acid was negatively correlated with precipitation in the coldest season and chlorogenic acid negatively correlated with precipitation in the driest month. Cryptochlorogenic acid was negatively correlated with precipitation in the coldest season and average temperature in the warmest season， but positively with selenium. Isochlorogenic acid B was mainly affected by soil factors. Specifically， it was positively correlated with available iron and molybdenum but negatively with total phosphorus and available phosphorus. Isochlorogenic acid A was positively correlated with molybdenum but negatively with the coefficient of variation of precipitation. Isochlorogenic acid C showed a positive correlation with exchangeable magnesium. Procyanidin A2 exhibited a positive correlation with molybdenum and a negative correlation with available potassium. Periplocin was negatively correlated with the coefficient of variation of precipitation. Conclusion:The correlation between the eight chemical components of P. forrestii and the ecological and soil factors has been clarified， which will provide reference for the introduction， cultivation， and standardized planting of P. forrestii and also a theoretical basis for further research on its ecological and soil factors and quality formation mechanism.
