Quality control of Platycodon grandiflorum (Jacq.) A. DC. based on value chains and food chain analysis.

Platycodon grandiflorum (Jacq.) A. DC. has been proposed as a medicine and food homology, thus playing an important role in disease prevention and health promotion, with great potential for research and value in clinical application. We aimed to analyze stakeholders' production behavior and financial performance from a value chain (VC) perspective and provide a basis for improving the quality of P. grandiflorum and the interests of stakeholders. P. grandiflorum collected from different producing areas were chemically analyzed, and the quality of platycodin D was evaluated. Rstudio3.6.0 was used to analyze the correlation between total platycodins (as platycodin D, platycoside E, and platycodin D) and platycodin D in P. grandiflorum, providing the basis for quality control of P. grandiflorum. In addition, we studied the anti-inflammatory and anti-cancer activities of P. grandiflorum extract under different links. Based on the food chain energy pyramid, the transfer efficiency of active components of P. grandiflorum in different links was studied. Accordingly, 10 different types of VCs were determined in producing P. grandiflorum. Our results show that vertical coordination has led to a more consistent traceability system and strict regulation of supply chains.
