| Abstract | ||
| Egyptian medicinal and aromatic plants (MAPs) sector suffers from poor drying conditions of the product in terms of quality and safety standards, lack of professional advisory services, in addition to a high undeveloped value chain. Four designs were established in this study and focused on different methods for chamomile drying, the results of the 8/9/2 (B) design of the solar-assisted stack dryer were a masterpiece and promising for drying chamomile plant. The results of volatile oil extraction showed that an increased yield of volatile oil extraction by 30 % compared with traditional drying methods (control). GC-MS analysis indicated the essential oil chemical composition for the new drying method, were found to be the main active compound Bisabolol oxide A which were 54% in 8/9/2 (B) design of the solar- assisted stack dryer compared with the control which was 38.36% in control. The study method was promising and distinctive because it increases the yield of volatile oil extraction, maintains chemical structure compared with the control. | ||
