The mineral contents, flavonoid, total phenol and anthocyanin contents of aerial parts of Sideritis and Origanum species. K was found high in both plant species. While K contents of Sideritis change between 10184.91 mg/kg (Sideritis libanotica Labill. subsp. linearis) and 17182.86 mg/kg (S. hispida), K contents of Origanum ranged from 10265.40 mg/kg (Origanum majorana) to 21293.79 mg/kg (O. vulgare). While the crude protein contents of Sideritis change between 1.55% (S. libanotica Labill. subsp. linearis) and 7.83% (S. perfoliata), protein contents of Origano species ranged from 1.99% (O. leptocladum) to 5.51% (O. vulgare). Also, the flavonoid contents of Sideritis plants change between 246.34 (S. libatotica Labill. subsp. linearis) and 2013.33 (S. hololeuca), the flavonoid contents of Origanum plants ranged from 345.38 (O. onites) to 1730.47 (O. majorana). The highest total phenol was found in S. congesta (6814.31) plant.
