Spectrum-Effect Relationship of Ethyl acetate Fraction in Ethanol Extract fromXiaoyaosan(XYE-E) for Antidepressant Effect Based on1H-NMR / 世界科学技术-中医药现代化

ABSTRACT

Thearticle is aimed to find the correlation between bioactive components of XYE-E and the antidepressant efficacy, by analyzing the immovability time in tail suspension test (TST) and forced swimming test (FST). Using the method of gray relational analysis, correlation analysis and regression analysis, relating the peak area of each common peak of1H-NMR spectra with the immovability time in TST or FST, we found that there were total 14 chemical components identified in the1H-NMR spectrum of XYE-E. Among them, 8 compounds, including saikosaponin a, saikosaponin c, saikosaponin E, saikosaponin F, saikosaponin G, saikosaponin b2, atractylenolide I and atractylenolide II, had significant correlation with antidepressant efficacy.
