Study on industrialization production technology of decoction pieces shuangfei of Platycodon grandiflorum

Objective:To establish industrialization production technology parameter for decoction pieces shuangfei of Platycodon grandiflorum.Methods: Taking platycodin D,polysaccharide and the appearance of the decoction pieces shuangfei of Platycodon grandiflorum as the quality evaluation indexes,we investigated the size of Platycodon grandiflorum,the best slicing extent,the best slicing thickness,drying temperature and drying time.Results: The optimal processing was as follows: the diameter of Platycodon grandiflorum was about 1.5 cm,moistend the selected Platycodon grandiflorum until the water content was 55%~60%.Then rolled them into 1.5 cm thickness pieces.Dryed them at 60 ℃ for 8~9 h and packed them after they were cold.Conclusion: The industrialization production technology for decoction pieces shuangfei of Platycodon grandiflorum is stable and the efficiency is improved.
