Chromatographic profile of RHTR by UPLC-MSE. TIC on ESI+ of AE (a) and FF (b) from RHTR showing the metabolic profiles of both samples with 173 preidentifications. The main compounds are indicated by the number of the corresponding order of appearance in Additional file 3: Table S1. The most abundant compounds in AE and FF are marked in red. The compound with higher relative abundance was identified, and a fingerprint of AE-RHTR by UPLC-PAD analysis at λ 280 nm is indicated in the corresponding inset. The results are representative of three biological replicates (n = 3, in triplicate)
