Investigation of the chemical structure and analgesic and anti-inflammatory properties of polysaccharides that constitute the dietary fibers of soursop (Annona muricata) fruit.

Soursop fruits are widely used in the folk medicine to treat a variety of health conditions. Once the chemical structure of dietary fibers from fruits is closely related to its biological functions in the human body, we aimed to explore structural features and biological activity of dietary fibers from soursop. Polysaccharides that constitute the soluble and insoluble fibers were extracted and further analyzed using monosaccharide composition, methylation, molecular weight determination and C NMR data.

Characterization and technological properties of peach palm (Bactris gasipaes var. gasipaes) fruit starch.

Peach palm fruit mesocarp (Bactris gasipaes var. gasipaes) is already consumed in the Northern region of Brazil, after its cooking and is known as a source of starch and carotenoids and like all fruits it has low storage stability. This work characterized the starch extracted from the mesocarp of peach palm fruit using with water in terms of its physical and chemical properties.

Pectic type II arabinogalactans from starfruit (Averrhoa carambola L.).

A structural characterization of polysaccharides from edible tropical fruit named starfruit (Averrhoa carambola L.) was carried out. After the purification steps, two homogeneous fractions were obtained.

Structural characterization of a rhamnogalacturonan I-arabinan-type I arabinogalactan macromolecule from starfruit (Averrhoa carambola L.).

A structural characterization of polysaccharides obtained from edible tropical fruit named starfruit (Averrhoa carambola L.) was carried out. After fractionation by freeze-thaw and Fehling precipitation, a pectic polysaccharide was obtained.
