Evaluation of a simple and promising method for extraction of antioxidants from sea buckthorn (Hippophaë rhamnoides L.) berries: Pressurised solvent-free microwave assisted extraction

► In this study we developed a new method of free-solvent microwave assisted extraction. ► Free solvent MAE gave an extract more antioxidant than conventional extraction methods. ► Free solvent MAE gave an extract richest than conventional extraction methods. ► Free solvent MAE allowed to extract phenolic compounds from sea buckthorn berries.
