Abstract
Chromatographic investigation of phenolic, flavonoid and coumarin contents of Thymus capitatus revealed the presence of 5 compounds of flavonoids,one phenolic acid and 3 compounds of coumarins, identified through Rf- values, complete and partial acid hydrolysis, UV spectral data, mass spectral data; 1H -NMR and 13C-NMR analysis, where the following flavonoids  were  proved  to be  present in Thymus  capitatus:  kaempferol –3–rutinoside, kaempferol–3–0-rhamnoside,4–0-glucoside, rutin, apigenin – 7 – 0- rhamanoglucoside, quercetin and P- coumaric acid. Meanwhile the coumarins were scopoletin, 6, 7 dimethoxycoumarin and herniarin. The percentage of total flavonoids reached 0.30%.
