Abstract
Different drying methods (Shade, Sun and Electric oven at 35Co and 50 Co were studied. Effects of these methods on percentage and composition of volatile oils and antioxidant activity (DPPH) of chamomile, peppermint, rosemary and sweet basil plants were studied.Using dry method in shade gave the highest mean value of DPPH% for all experimental plants compared with other drying methods. Shade drying generally seemed better, especially with regard to essential oil and major’s compoundspercentage of plants experiment followed by oven at (35 Co) drying method. ADDITIONAL INDEX words: Drying methods, chamomile, peppermint, rosemary and sweet basil, DPPH%, chamazulen, menthol, borneol and linalool
