Representative ¹H NMR spectrum of one extract of S. rosmarinus (accession 2, Supplementary Table S1 ), from δ _H 0.0 to 8.5 ppm, with annotation of the metabolites of the Chenomx 500 MHz custom library (CCL). Regions δ _H 0.9–2.1, δ _H 3.6–5.2, δ _H 6.0–8.1 (dotted boxes) were expanded. The peaks used for the quantification of the identified CCL metabolites are annotated with numbers. Keys: 1, 12-O-methylcarnosic acid; 2, 7-O-methylrosmanol; 3, methylrosmarinate; 4, genkwanin; 5, epicatechin; 6, isorhamnetin-3-O-β-D-rutinoside; 7, carnosic acid; 8, diosmetin; 9, luteolin; 10, scutellarein; 11, acacetin; 12, carnosol; 13, catechin hydrate; 14, gallic acid; 15, rosmarinic acid; 16, ferulic acid; 17, caffeic acid; 18, coumaric acid; 19, chlorogenic acid; 20, rutin; 21, quercetin; 22, apigenin; 23, isorosmanol; 24, apigenin-7-O-β-D-glycoside; 25, kaempferol; 26, isorhamnetin-3-O-rutinoside (narcissin); 27, epiisorosmanol.
