Therefore, the in-depth research, development and utilization of resveratrol is particularly important and has economic significance and social value. This paper reviews the research of resveratrol in recent years at home and abroad in terms of extraction technology and antioxidant activity. It was found that the current extraction methods of resveratrol were divided into ultrasonic extraction method, enzyme extraction method, microwave-assisted extraction method, supercritical fluid extraction method, etc. through the comparative analysis of various methods, in order to improve the extraction efficiency of resveratrol, and the antioxidant properties of resveratrol were reviewed, in order to provide a reference for the further development of resveratrol.","PeriodicalId":16596,"journal":{"name":"Journal of Organic Chemistry Research","volume":"13 02","pages":"146-154"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pdf.hanspub.org/jocr_2970303.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147903765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the correlation coefficient between the average SPAD values at the middle 1/2 and upper and lower 3cm of rice leaves and the average SPAD values of the entire leaf was the highest. The average value, standard deviation, and coefficient of variation of SPAD values on both sides of rice leaves are as follows: smooth side > rough side, smooth side < rough side, smooth side < rough side, with a close 1:1 relationship between the front and back sides. The correlation between the color feature parameter G-B value and SPAD value is the best, and a functional relationship model is constructed, Y SPAD = − 0.4541X G-B + 64.4618 (n = 48, df = 45, R 2 = 0.7475, F = 133.2052, p < 0.01). In summary, color recognition devices based on smartphones can provide a new method for monitoring rice nitrogen nutrition, replacing expensive, cost-effective, and cumbersome instruments.","PeriodicalId":16596,"journal":{"name":"Journal of Organic Chemistry Research","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81056103","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}

Eight Guizhou green teas were produced with two different rolling degrees, no rolling and heavy rolling, different aroma raising temperatures, and different aroma raising times. By detecting the quality components of tea polyphenols, amino acids, and phenol ammonia ratio, the quality of Guizhou green tea produced with no rolling and heavy rolling was analyzed and evaluated in multiple dimensions, by combining artificial sensory evaluation and intelligent sensory evaluation analysis, the optimal processing technology for Guizhou green tea has been identified. Results: The results showed that green tea that was not rolled and baked at 60 ˚C until fully dried, and flavored at 75 ˚C for 30 minutes had high polyphenol and amino acid content and low phenol ammonia ratio, excellent taste quality, and the highest sensory evaluation score. Conclusion: Sensory evaluation combined with physicochemical index analysis shows that the comprehensive quality of green tea is the best when it is not rolled, baked to dryness at 60 ˚C , and flavored at 75 ˚C for 30 minutes.","PeriodicalId":16596,"journal":{"name":"Journal of Organic Chemistry Research","volume":"118 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89348039","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}
