The changes of intestinal microflora in feces were sequenced by amplicon of 16S rDNA. The results showed that compared with the blank control group, all the doses of pueraria decreased inflammatory factors and improved the immune state of the body, and the low dose was the most significant (P < 0.05). Flow cytometry results showed that the number of T and B lymphocytes in serum of pueraria root extract in each dose group was significantly increased (P < 0.05), and the increase rate was most significant in low dose group (P < 0.01). 16S rDNA amplified sequencing results showed that pueraria root extract could specifically increase the abundance of immune-related intestinal microorganisms, such as Clostridium difficile, Roche, Parabacteroides dieldii , enterococcus, etc. The difference analysis of Alpha diversity index between groups suggested that pueraria root could improve the abundance and distribution uniformity of intestinal microorganisms. PCoA analysis indicated that pueraria could significantly change the species abundance and composition of intestinal microorganisms. Therefore, pueraria root can improve immune function, reduce inflammatory factors, increase the number of T and B lymphocytes, besides, it may play an immunomodulatory role by changing the intestinal microflora, such as parabens Diels, and increasing the diversity of intestinal microflora","PeriodicalId":12938,"journal":{"name":"Hans Journal of Food and Nutrition Science","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80763456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Eigh-teen batches of Fenggang zinc-selenium tea samples in different processing stages were pre-treated by wet digestion and microwave digestion. The contents of zinc and selenium in Fenggang zinc-selenium tea samples during processing were determined by inductively coupled plasma mass spectrometry (ICP-MS), and their contents were analyzed by systematic difference analysis and systematic cluster analysis. Results: The contents of zinc and selenium in Fenggang Zinc and Selenium tea at different processing stages were all within the standard range, and there was no significant difference in the contents of zinc and selenium in Fenggang zinc and selenium tea at different processing stages (P > 0.05), which was consistent with the results of systematic cluster analysis. Conclusion: The study showed that the contents of zinc and selenium in Fenggang Zn-selenium tea had no significant difference in each processing process, indicating that the processing technology had little influence on the tea.","PeriodicalId":12938,"journal":{"name":"Hans Journal of Food and Nutrition Science","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90472471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The overall average oil content of dried whole fruit of introduced seabuckthorn was 16.59% (114 samples), the lowest content was more than 10%, and the highest content “201322” reached 23.50%. The oil content of introduced seabuckthorn dry pulp was 20.23% ± 6.13%, which was 0.97% higher than 19.26% ± 7.44% of dry seed. There was little difference in oil content between pulp and seed. The oil content of dry whole fruit of introduced seabuckthorn was 16.59% ± 5.91%, which was 0.97% higher than 15.62% ± 5.05% (28 samples) of hybrid seabuckthorn. There was also little difference in oil content between introduced and hybrid seabuckthorn. The oil content of dry whole fruit in Xinjiang is the highest, up to 16.09% ± 5.70%, the second and third was 14.50% ± 8.88% in Liaoning and 11.75% ± 8.71% in Heilongjiang respectively. There was a large gap in the oil content of dry whole fruit among the three places. Seabuckthorn was introduced and sampled for three consecutive years to determine the oil content of dry whole fruit, which was 10.63% ± 4.04% in 2016, 21.90% ± 5.61% in 2017 and 15.83% ± 1.83% in 2018. The oil contents of the dry whole fruit in the three years showed obvious fluctua-tions of “small-large-small”. Though both the oil content of introduced seabuckthorn and hybrid seabuckthorn were very high, there were still large differences among specific varieties. The va-rieties with high oil contents, such as “201322” “201308” “201313”, etc., could be selected for es-tablishing seabuckthorn industrial raw material forest with oil as the main goal for comprehen-sive development and utilization in the suitable areas in China.","PeriodicalId":12938,"journal":{"name":"Hans Journal of Food and Nutrition Science","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78526595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
