Chemical Examination of Citrus sinensis Flavedo Variety Pineapple
نویسندگان
چکیده
Phytochemical examination of Citrus sinensis flavedo var. Pineapple resulted in the isolation of six compounds characterized as tetracosane, ethyl pentacosanoate, tetratriacontanoic acid, tangertin, beta-sitosteryl-beta-D-glucoside and 3,5,4'-trihydroxy-7,3'-dimethoxy flavanone 3-O-beta-glucoside. Of these 3,5,4'-trihydroxy-7,3'-dimethoxy flavanone 3-O-beta-glucoside is a hitherto unreported compound.

Cellulase Activity, Endogenous Abscisic Acid, and Ethylene in Four Citrus Cultivars during Maturation.
At maturity, the fruit of two early maturing orange cultivars, Hamlin and Pineapple (Citrus sinensis [L.] Osbeck), contained more ethylene and abscisic acid than the late maturing Valencia and Lamb Summer (C. sinensis [L.] Osbeck) cultivars. Ethylene (up to 95 nl/l in internal atmosphere) and abscisic (50 mug/kg dry weight flavedo) increased most rapidly in Pineapple, leading to increased cellu...

Antibacterial activity on ATCC strains of Escherichia coli, Salmonella enterica, Salmonella enteritidis, and Salmonella choleraesuis and spasmolytic effect on contraction on rat ileum trips were determinate. Eight organic extracts (hexanic and methanolic) of albedo (mesocarp) and flavedo (pericarp) of two varieties (Valencian and National) of Citrus sinensis (L.) Osbeck of Yucatán, México, were...
متن کاملCharacterization of Pinalate, a novel Citrus sinensis mutant with a fruit-specific alteration that results in yellow pigmentation and decreased ABA content.
The characterization of a novel mutant, named Pinalate, derived from the orange (Citrus sinensis L. Osbeck) Navelate, which produces distinctive yellow fruits instead of the typical bright orange colouration, is reported. The carotenoid content and composition, and ABA content in leaf and flavedo tissue (coloured part of the skin) of fruits at different developmental and maturation stages were ...
متن کاملRidges and Sectors Induced in Olive Fruits by Fumigation with Hydrocyanic Acid.
In a previous paper (1), the authors have shown that the fumigation of citrus trees with hydrocyanic acid (HCN) for pest control, at a time of the year when the fruit buds are in a certain stage of development, produced ridges and sectors in the outer portion of the peel (flavedo) of the fruit. In the navel orange, Valencia orange and grapefruit varieties, fumigation of trees in February produc...
