Assembly of synthesis pathway of naringenin, shown by Fig.1.

Fermentation results by HPLC test

During the HPLC testing, we purchased final and intermediate metabolism products standard, naringenin, taxifolin, eriodictyol and catechin, and used them in the subsequent HPLC tests.

Catechin and other intermediate metabolites were confirmed by comparing the samples with the standard.
