Physiological studies on the chemical constituents of three Lamiaceae species, Phlomis aurea, Ballota undulata, and Nepeta septemcrenata, growing in different circumstances in South Sinai, Egypt.

Abstract

The goal of this study was to see how habitat differences affected chemical constituents of 3 different species: Phlomis aurea, Ballota undulata, and Nepeta septemcrenata. All analyses were conducted in the Saint Katherine Protectorate, South Sinai, Egypt, across four wadis (Wadi Gebal, Wadi Graginya, Wadi El-Arbae'en, and Wadi Abu-Tuweita) and the Musa's Gorge. In all species, there was a noticeable variance in the biochemical content of the examined plants across different habitats. Phlomis aurea in Wadi Gebal had the highest total soluble carbohydrate value, while Nepeta septemcrenata at Musa's Gorge had the highest water-soluble protein value. In the same period, Phlomis aurea reached its highest level of free proline at Musa's Gorge and total phenols at Nepeta septemcrenata plants reached their highest level (0.892mg/g dry wt) at Wadi El-Arbae'en.
