Abstract

Seedlings of Rumex acetosa L. (sorrel) were grown in floating system and two consecutive cuts took place: 15 (C1) and 30 (C2) days after sowing. An untargeted metabolomics approach was utilised to fingerprint phenolics and other health-related compounds in sorrel leaves, as well as to unveil differences between the two cuts. The untargeted approach allowed to putatively identify 458 metabolites considering both the cuts. Three new terpenoids and two new phenylpropanoid glycosides (dihydrosyringin and dihydroconiferin) with antifungal and anti-inflammatory activity were annotated. Overall, leaves from C2 had lower level of secondary metabolites (44 were down-accumulated), especially sesquiterpenes and stilbenes. Conversely, anthocyanins showed a relevant increase in C2 than in C1 leaves. The dataset suggests that sorrel leaves represent a good source of nutraceutical compounds and unveils the pivotal effect of pre-harvest factor in secondary metabolite profile.
