Flavonoids are a group of polyphenolic compounds ubiquitous in many plants including fruits, vegetables, nuts, seeds, grains, tea and wine (Hollman & Katan, 1999). Flavonoids belong to two classes i) Flavanones and ii) Flavones. The most common flavanones are hesperetin from oranges and naringenin from grapefruit. The most common flavones, also known as polymethoxylated flavones, are tangeretin...

Fifteen polymethoxyflavones (PMFs) and hydroxylated PMFs were isolated from sweet orange (Citrus sinensis) peel extract and synthesized to investigate their biological activity. All obtained compounds were tested in HL-60 cancer cell proliferation and apoptosis induction assays. While some PMFs and hydroxylated PMFs had moderate anti-carcinogenic activities, 5-hydroxy-6,7,8,3',4'-pentamethoxyfl...

Spore-forming bacteria are a great concern for fruit juice processors as they can resist the thermal pasteurization and high hydrostatic pressure treatments that juices receive during their processing, thus reducing microbiological quality safety. In this context, our objective was to evaluate efficacy of Ultraviolet-C (UV-C) light at 254 nm on bacterial spores Alicyclobacillus acidoterrestris,...

India is sitting on a gold mine of well-recorded and traditionally well practiced knowledge of herbal medicine. General phytochemical screening of Citrus sinensis (Orange) belonging Rutaceae family revealed the presence of flavones glycoside. The aim of this study is to identify and characterize the bioactive principle compound (Hesperidin) from the dried peel of C. sinensis fruit. It has wide ...

the oxidation of lipids change organoleptical properties, nutritional value and shelf life of oils, and produce undesirable compounds that are not safe for customer”s health. there is many methods for prevention of oxidation such synthetic antioxidants, (bha, bht, tbhq, gallatester).synthetic antioxidants, have undesirable effects such cancer, motation in human body, therefore it was removed fr...

Carotenoids are pigments found in various types of fruits and vegetables that provide yellow, orange, red colors. This study aimed to extract yellow pumpkin skin using edible oil solvents. The extraction process was carried out ultrasound-assisted (UAE) method with virgin coconut (VCO) palm kernel (PKO). Yellow peel powder sizes 40 mesh 100 were extracted variations time (30 minutes, 60 90 minu...

Water stress affects many agronomic traits that may be regulated by the phytohormone abscisic acid (ABA). Within these traits, loss of fruit quality becomes important in many citrus cultivars that develop peel damage in response to dehydration. To study peel dehydration transcriptional responsiveness in harvested citrus fruit and the putative role of ABA in this process, this study performed a ...

A series of monoliths are prepared from orange peels and chemically activated with H 3 PO 4 , KOH, ZnCl 2 , and water vapor without a binder. The monoliths were characterized by N 2 adsorption-desorption isotherms at 77 K, Boehm titrations and XPS. Thereafter, monoliths were tested for their ability to establish NO x retention. The results show that the retention capacities of NO x were a funct...
