Optimization of Technology for Ultrasonic-assisted Extraction of Volatile Oil from Rosmarinus officinalis

Rosemary, which has physiological effects such as protecting human cellular tissues, preventing the occurrence of many diseases, protecting the cardiovascular and cerebrovascular circulation system, anti-cancer and anti-aging, has broad application prospects in food, cosmetics, medicine and other fields.

Objective： To optimize the ultrasonic-assisted extraction process of volatile oil from Rosmarinus officinalis  

Method：The extraction technology of volatile oil from Rosmarinus officinalis L.is optimized through single factor test and orthogonal test,with the extraction yield of volatile oil as the evaluation index.Result：The order of influencing factors of ultrasonic-assisted extraction of volatile oil from Rosmarinus officinalis L.is solvent to material ratio,ultrasonic time and extraction temperature and all of them are significant factors.The optimum extraction parameters are as follows：the solvent to material ratio of 10 （mL/g）,the extraction temperature of 50 ℃ and the ultrasonic time of 35 min.Under the optimum conditions,the extraction yield of volatile oil can reach 1.536%.Conclusion：This extraction process is rational,stable and feasible,and can provide useful information for industrial production.

This ultrasonic assisted extraction Rosmarinus officinalis method has simple process, economy, and high extraction rate.

This ultrasonic assisted extraction equipment can be used for various process operations in the traditional Chinese medicine, food, and chemical industries, such as atmospheric pressure, micro pressure, water decoction, warm soaking, hot reflux, forced circulation, percolation, aromatic oil extraction, and organic coal recovery. It is particularly suitable for hospitals, pharmaceutical factories, and research institutions to develop new products and for small-scale production.
