Comparison of nutritional quality during fruit development of Phyllanthus emblica
摘要
Abstract
To decipher the dynamic changes in nutritional characteristics of Phyllanthus emblica fruits during fruit development,this study measured the nine nutritional components in fruit during four fruit development stages.For comparison purposes,two varieties of P.emblica cv.'Gaoligong Mountain'and'Baoshan No.2'were used as samples.Correlations and principal component analysis of the quali-ty indicators of fruits were conducted to determine the optimal time of harvest.Results showed significant differences(P＜0.01)between each of the quality indicators in different developmental stages.Moreover,there were different trends of changes in each quality indicator during different development stages.Total acid,total sugar,vitamin C,and polyphenol content tended to increase and then decrease as the fruit developed,while soluble solids content tended to decrease and then increased.A strong correlation(r＞0.9)was observed between total sugars and polyphenols in both two varieties.Results obtained from the current report showed that the best time to harvest both two va-rieties was around October 15.At this time,the highest contents of total acid,vitamin C,total sugar,tannins,and polyphenols were ob-served in both two varieties,as well as the highest content of soluble solids was observed in'Gaoligong Mountain'and the highest content of gallic acid was observed in'Baoshan No.2'.关键词
