Analysis method for antioxidant activity of peganum harmala plants from different producing areas

The invention belongs to the technical field of metabonomics, and particularly discloses an analysis method for the antioxidant activity of peganum harmala plants from different producing areas based on a metabonomics technology. The method comprises the following steps: analyzing peganum harmala from different producing areas, and acquiring metabolite information, mineral element content data and DPPH free radical semi-inhibition concentration data in a peganum harmala extract; screening out differential metabolites according to the collected nuclear magnetic resonance spectrogram data, and analyzing the correlation between the semi-inhibitory concentration and the mineral element content and the correlation between the semi-inhibitory concentration and the differential metabolite content. According to the method, a nuclear magnetism, inductively coupled plasma atomic emission spectrometry and spectrophotometric combined technology is adopted, peganum harmala plants in different regions are taken as research
