The objective of the present work is extraction of pectin from waste of orange fruit peel and further characterization for useful alternative pharmaceutical excipient. The pectin was subjected to phytochemical and physicochemical characterization of its safety and suitability to use as binding and suspending agent. FT-IR spectroscopy, DSC studies were performed for drug, orange peel pectin powd...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were com...

This study evaluated the effect of foliar biostimulants on fruit quality of adult 'Valencia' orange and 'Biancolilla' olive trees. Half of the selected orange and olive trees were sprayed twice before harvest with the SUNRED® commercial mix containing phenylalanine, methionine, mono-saccharides and oxylipins from plant extracts as well as potassium salts and urea. Orange and olive yields and fr...

The aim of this study is to develop an extraction method for the producing of a safe and efficient source of antioxidant compounds from fresh and pre-treated sweet orange (Citrus sinensis cv shahsavari) peel. Three types of solvents (100% ethanol, 100% water and ethanol-water mixtures at the ratios of 35:65 and 65:35, v/v), three duration times (60, 120 and 240 min) were chosen as the parameter...

Production of intracellular β-xylosidase was studied in cultures of Penicillium janthinellum grown on citrus fruit waste supplemented cultivation media. Both dried orange peel and sweet lime peel could induce the production of this enzyme. The working strain showed a pronounced optimum pH and temperature for β-xylosidase production at 6.0 and 27 °C, respectively. The enzyme production was found...

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...

the use of natural extracts as one of good antioxidant source is increasing to improve fish quality. the present study aims at investigating antioxidant effect of orange peel extract on the quality of common carp fillet during refrigerated storage (4°c). fish fillets were treated by 0, 1 and 5 % concentration of orange peel extract, packed and then stored in refrigerator. chemical parameters (p...

The aim of present work was to extract pectin from dried orange fruit peels to assess its binding property in tablets using paracetamol as model drug. Initially orange fruit peel powder was subjected to simple water based soxhlet extraction and pectin was isolated using ethyl alcohol as precipitating agent. Thereafter, four batches were formulated using pectin in different proportions. A refere...

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 effect of some natural wastes (orange pomace, orange peel, lemon pomace, lemon peel, apple pomace, pear peel, banana peel, melon peel and hazelnut shell) on the production of xylanase from Trichoderma harzianum 1073 D3 has been studied and maximum activity has been observed on melon peel (26.5 U/mg of protein) followed by apple pomace and hazelnut shell. Also, molasses could be used as an a...
