The present invention, in preparing a medicinal Platycodon root powder, (i) decomposes the cell wall by enzyme treatment, (ii) forms an antimicrobial and moisture-protective layer through coating with grapefruit seed extract and fructooligosaccharide, and (iii) recovers and concentrates residual saponins through low-temperature extraction and re-mixing, thereby providing a powder having high saponin and flavonoid contents and excellent storage stability without high-heat processing. This powder has high utility as a material for medicinal Platycodon root syrup, powdered beverages, and health functional food ingredients.

The application belongs to the technical field of pharmaceutical compounds, and particularly relates to a platycodon grandiflorum polysaccharide as well as a preparation method and application thereof. The platycodon grandiflorum polysaccharide is named as PGP-1. The platycodon grandiflorum polysaccharide PGP-1 is simply and efficiently extracted from the platycodon grandiflorum root through an improved extraction process. Pharmacological activity shows that the PGP-1 has significant immunoregulatory activity and inhibits cancer cell proliferation, which indicates that the PGP-1 can be applied to preparation of immunoregulatory drugs or antitumor drugs, and provides a new choice for development of immunoregulatory drugs and antitumor drugs.

The invention discloses burkholderia paragallinarum for improving the quality of platycodon grandiflorum as well as a fungicide and application of the burkholderia paragallinarum. According to the invention, an endophytic strain Paraburkholderia strudomiana R23C2 capable of promoting the accumulation of the triterpenoid saponin components of platycodon grandiflorum is separated and screened from platycodon grandiflorum roots, a compound microbial agent is designed based on the strain, and experimental studies prove that the strain and the compound microbial agent can promote the accumulation of the triterpenoid saponin components of platycodon grandiflorum, so that the yield of the platycodon grandiflorum triterpenoid saponin components is increased, and the yield of the platycodon grandiflorum triterpenoid saponin components is increased. And the economic benefit of the platycodon grandiflorum planting industry can be effectively improved by popularization and application.

The application provides osmanthus fragrans plant extract mosquito repellent spray with long-acting mosquito repellent and itching, swelling relieving effects and a preparation method thereof, and relates to the technical field of mosquito repellent products.
