The medicinal composition of rosemary essential oil has led to its widespread use in the food, cosmetic, health and herbal industries. In the present work, seasonal variations of essential constituents of essential oil, essential oil yield were evaluated. The predominant components of rosemary were: camphene, limonene, α-pinene, camphor, borneol, linalool, 1,8-cineole, (E)- caryophyllene and bornyl acetate. The highest rate of linalool was seen in summer, while camphor, limonene and borneol showed the highest percentage in cold season. Some of the compounds such as α-pinene, camphene, bornyl acetate and ()- caryophyllene in the spring with the activation of some important plant enzymes such as peroxidase showed the highest amount. It is hoped that this research will provide very useful information about the best time to harvest the valuable rosemary plant and can be useful for the health, food and herbal industries that use this plant.
迷迭香精油的药用成分使其在食品、化妆品、健康和草药行业得到广泛应用。本研究评估了迷迭香油的主要成分和精油产量的季节性变化。迷迭香的主要成分有：莰烯、柠檬烯、α-蒎烯、樟脑、龙脑、芳樟醇、1,8-桉叶素、(E)-丁香烯和乙酸龙脑酯。夏季时，芳樟醇含量最高，而樟脑、柠檬烯和龙脑在寒冷季节的百分比最高。春季的一些化合物，如α-蒎烯、莰烯、乙酸龙脑酯和( )-丁香烯，随着一些重要植物酶（如过氧化物酶）的激活，含量最高。希望本研究能为收获珍贵迷迭香植物的最佳时间提供非常有用的信息，并能为使用该植物的健康、食品和草药行业提供帮助。
