The present work is the first report on the ingredients of the P. × commixta hybrid, a plant of the genus Phlomis . So far, thirty substances have been isolated by various chromatographic techniques and identified by spectroscopic methods, such as UV/Vis, NMR, GC-MS and LC-MS. The compounds are classified as flavonoids: naringenin, eriodyctiol, eriodyctiol-7-O- β -D-glucoside, luteolin, luteolin-7-O- β -D-glucoside, apigenin, apigenin-7-O- β -D-glucoside, diosmetin-7-O- β -D-glucoside, quercetin, hesperetin and quercetin-3-O- β -D-glucoside; phenylpropanoids: martynoside, verbascoside, forsythoside B, echinacoside and allysonoside; chromene: 5,7-dihydroxychromone; phenolic acids: caffeic acid, p -hydroxybenzoic acid, chlorogenic acid, chlorogenic acid methyl ester, gallic acid, p -coumaric acid and vanillic acid; aliphatic hydrocarbon: docos-1-ene; steroids: brassicasterol and stigmasterol; a glucoside of allylic alcohol, 3-O- β -D-apiofuranosyl-(1→6)-O- β -D-glucopyranosyl-oct-1-ene-3-ol, was fully characterized as a natural product for the first time...
