Comparison of storability and seasonal changes on new flavonoids, polyphenolic acids and terepene compounds of Citrus paradisi (grapefruit) cv. shamber through advance methods

Abstract The significance of grapefruit is laying in its unique medicinal values and health related compounds. This article discusses the influence seasonal variations storage periods on synthesis accumulation new polyphenolic compounds, terpenes, flavonoids sugars profiling ( Citrus paradisi ) cv. shamber juice were evaluated under advance techniques. individual sugar (total sugar, fructose, glucose sucrose) phenolic acids essential groups terpene compounds measured at five harvesting times, from early to late stages compare days (0, 15, 30, 35, 45 65). higher contents obtained December harvested fruits while comparison 65 reduced however others maintained Limonene, Quercetin, Perillyl alcohol Monoterpenes 35 day showed constant terpenes little reduction terepene storage. It may conclude that mid date was best for good all these present amount
