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

ABSTRACT: 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 D₃) 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.

Project description:BackgroundCampanulaceae species are known to have highly rearranged plastid genomes lacking the acetyl-CoA carboxylase (ACC) subunit D gene (accD), and instead have a nuclear (nr)-accD. Plastid genome information has been thought to depend on studies concerning Trachelium caeruleum and genome announcements for Adenophora remotiflora, Campanula takesimana, and Hanabusaya asiatica. RNA editing information for plastid genes is currently unavailable for Campanulaceae. To understand plastid genome evolution in Campanulaceae, we have sequenced and characterized the chloroplast (cp) genome and nr-accD of Platycodon grandiflorum, a basal member of Campanulaceae.ResultsWe sequenced the 171,818 bp cp genome containing a 79,061 bp large single-copy (LSC) region, a 42,433 bp inverted repeat (IR) and a 7840 bp small single-copy (SSC) region, which represents the cp genome with the largest IR among species of Campanulaceae. The genome contains 110 genes and 18 introns, comprising 77 protein-coding genes, four RNA genes, 29 tRNA genes, 17 group II introns, and one group I intron. RNA editing of genes was detected in 18 sites of 14 protein-coding genes. Platycodon has an IR containing a 3' rps12 operon, which occurs in the middle of the LSC region in four other species of Campanulaceae (T. caeruleum, A. remotiflora, C. takesimana, and H. asiatica), but lacks accD, clpP, infA, and rpl23, as has been found in these four species. Platycodon nr-accD contains about 3.2 kb intron between nr-accD.e1 and nr-accD.e2 at the same insertion point as in other Campanulaceae. The phylogenies of the plastid genomes and accD show that Platycodon is basal in the Campanulaceae clade, indicating that IR disruption in Campanulaceae occurred after the loss of accD, clpP, infA, and rpl23 in the cp genome, which occurred during plastid evolution in Campanulaceae.ConclusionsThe plastid genome of P. grandiflorum lacks the rearrangement of the IR found in T. caeruleum, A. remotiflora, C. takesimana, and H. asiatica. The absence of accD, clpP, infA, and rpl23 in the plastid genome is a synapomorphic characteristic of Campanulaceae. The chloroplast genome phylogeny supports the hypothesis that chloroplast genomic arrangement occurred after accD nuclear transfer and loss of the four genes in the plastid of early Campanulaceae as a lineage of asterids.
