A metabolomics discrimination-based strategy for screening the antithrombin active markers of perilla seeds: A natural oil crop.

Natural crops oil with high nutritional value has gradually attracted attention. Perilla seeds are regarded as a source of functional edible oil in America, Asia and European countries due to its abundant nutrients. In this research, samples were extracted by different polarity solvents and evaluated their thrombin inhibition activities in vitro. Metabolomics combined with chemometrics revealed the antithrombin active markers of perilla seeds. The enzyme kinetics and molecular docking results were useful in clarifying their inhibition of thrombin. The orthogonal experimental design was applied to optimize the extraction process of six antithrombin active markers from perilla seeds. The results showed that rosmarinic acid, luteolin, luteolin-7-O-glucoside, α-linolenic acid, linoleic acid, and oleic acid were screened out as functional and active markers. Besides, perilla seeds as a natural oil crop had the potential of antithrombin. It can also be applied in the food field because of its nutraceutical functions. Metabolomics combined with chemometrics will facilitate the discovery of functional, active markers in perilla seeds, which is conducive to accurate quality control.
