Arabinan-rich pectic polysaccharide fraction from Malpighia emarginata fruits alleviates inflammatory pain in mice.

Malpighia emarginata (Malpighiaceae), popularly known as "acerola", is a tropical and subtropical fruit native to the Americas. Despite its high vitamin C content, which gives it a high antioxidant property, soluble dietary fibers, such as polysaccharides, are also abundant constituents of acerola (10% of the dried fruit). The acerola cold-water soluble (ACWS) fraction presented anti-fatigue and antioxidant effects in vivo and in vitro.

Pre-season in soccer: a paradox between a high volume of technical/tactical training and improvement in the neuromuscular performance of elite women soccer players.

Background: there is a paradox between the development of strength-power abilities and the high volume of technical/tactical training in elite soccer players during the pre-season. This concurrent effect between aerobic and neuromuscular training regimes induce impairment in power performance.

Methods: this study aimed to investigate the effect of an equalized program of strength-power training (4-5 sessions/week) and soccer training (4-6 sessions/week) in power and aerobic performance during 8-weeks of pre-season in elite women soccer players.

Young culm of Dendrocalamus asper, Bambusa tuldoides and B. Vulgaris as source of hemicellulosic dietary fibers for the food industry.

Bamboo is a grass that has gained economic attention in the food industry as a source of dietary fiber, and the young bamboo culm may be an alternative to supply fibers to the market. The objective was to evaluate and characterize different portions (bottom, middle and top) of the young bamboo culm fibrous fractions from Dendrocalamus asper, Bambusa tuldoides and B. vulgaris regarding their color parameters, physicochemical composition and hemicellulosic polysaccharide characterization.

Anti-fatigue activity of an arabinan-rich pectin from acerola (Malpighia emarginata).

A fraction composed of an arabinan-rich pectin was extracted from acerola fruit (Malpighia emarginata) and named ACWS. This fraction presented 93% of total carbohydrate, relative molecular weight of 7.5×10g/mol, galacturonic acid, arabinose, galactose, xylose and rhamnose in 52.

Structure and intracellular antioxidant activity of pectic polysaccharide from acerola (Malpighia emarginata).

Malpighia emarginata is a tropical fruit plant, found naturally in the Caribbean islands and South America that produces an edible fruit known as acerola or Barbados Cherry. Its polysaccharides were obtained by aqueous extraction, subjected to a freezing and thawing process and ultrafiltration. A homogeneous fraction (ACWS-01E) was analyzed by sugar composition, HPSEC, methylation and NMR spectroscopy analyses.
