The extraction of paeonal from cotex moutan
Abstract:The experimental conditions were obtained by positive coross trial and got the paeonol from moutan by the method of water vapour distillation.Thus, The best parameter of technology showed that the distillation time of five hours,the flow rate of five milliliters per minute and the water multiple of eighteen.
Key words: paeonol; cotex moutan; water vapour distillation
