Chaenomeles speciosa (Sweet) Nakai), belonging to the family Rosaceae papaya, is widely planted in China, mainly distributed in Shaanxi, Gansu, Hubei, Shandong and other places, with a long planting history
.
Wrinkled papaya contains a variety of nutrients such as sugar, protein, fat, etc.
, and also contains polyphenols, flavonoids, polysaccharides, saponins and other bioactive ingredients, which has the effect
of regulating qi, relaxing muscles and activating the body, and gastric dampness.
In recent years, due to the high nutritional value and medical health care functions of wrinkled papaya, more and more researchers are committed to the research of
wrinkled papaya.
Some studies have shown that wrinkled papaya has antioxidant, anti-inflammatory, bacteriostatic, antitumor and other biological activities
.
Although wrinkled papaya has been used in the treatment of inflammation, the anti-inflammatory effects of phenolic substances in it and their molecular mechanisms are unknown

In recent years, Yuncheng County, one of the "three breakthroughs" counties of our hospital, has actively introduced and standardized the planting of wrinkled papaya, which has become an important economic resource
for the county's rural revitalization.
Based on the rich resources of wrinkled papaya in China, this study studied the anti-inflammatory effect and mechanism of phenolic extract in LPS-induced RAW264.
7 cell inflammation model for the first time, which provided a theoretical basis for the application of phenolic substances in wrinkled papaya in anti-inflammatory treatment, and at the same time, it will effectively enhance the industrial value of wrinkled papaya, which has important economic value and social significance
for promoting the development of wrinkled papaya industry in China 。 Graduate student Hu Fuxia is the first author, and Liu Chao, associate researcher of the Institute of Agricultural Products Processing and Nutrition, is the co-first author, and the paper has been strongly supported
by the major scientific and technological innovation project of the key research and development plan of Shandong Province.
