Understanding the diversities in medicinal and aromatic plants is essential for comprehensively characterizing their chemical composition, especially when dealing with specimens from various regions with distinct geographical backgrounds. The purpose of this study was to evaluate the chemical characteristics and economic yield of anise fruit and curled parsley plant volatile oils under various Egyptian locations. The study was carried out over two consecutive seasons, 2021/2022 and 2022/2023. Six sites were selected to assess anise and curled parsley plants cultivation across three distinct governorates: A) El-Minia Governorate (Old Land, Biosystem Farm, and Sekem Farm), B) Bahariya Oasis (Lena Farm and Sekem Farm), and C) Aswan Governorate (Wadi El-Noqra).The investigation revealed significant effects of location on the weight and yield of anise fruit, the old land in El-Minia's Governorate had the greatest values. The percentages of essential oils were different by location, with Sekem Farm (Oasis) having the greatest amount. Old Land (El-Minia) had the greatest amount of essential oil per plant. The GC-MS method identified the major components of anethole and estragole, these components were different in composition across locations. For the curled version of Parsley, the Lena Farm (Oasis) farm's herb weight and essential oil were the highest. In Egypt's cross country, the composition of oil was erratic in Parsley, the Wadi El-Nokra (Aswan) district had a different composition than the Lena Farm district. The appropriate choice of agro-ecological zone and location is pivotal in enhancing the essential oils' content and composition. El-Minia's clay-loam soil is beneficial to the cultivation of anise. Conversely, El-Bahariya Oasis has a sandy soil type and is ideal for cultivating fluffy Parsley.
