“…These tannin contents are higher that those reported by other Acacia gums submitted to purification process, such as A. tortuosa, A. macracantha and A. glomerosa (Abed El Kader et al, 2003). The gum samples from A. farnesiana and A. cochliacantha were not purified and could present condensed tannins free and tannins joined to protein fraction and fibre.…”

“…This indicates that the C.vitifolium gum does not retain a quantity of water such as to influence the activation of enzymes http://ijfaas.com and the proliferation of organisms during food storage and transportation (Sonnergaard, 1999 The ash percentage, Table 1, is relatively high, above the 4% maximum limited reported by FAO (1998) for food and pharmaceutical quality gum arabic (Yusuf, 2011) ; nevertheless it suggests that is present an important proportion of inorganic constituents. Most gum exudates are polysachaccharides containing various metal ions which are partially neutralizing the carboxylic groups of the uronic acids (El Kader et al, 2003). The cationic composition of the ash, Table 2, demonstrated that the three major metallic cations are Ca> Mg> Na which may be a good source of mineral nutrition.…”

The physicochemical parameters of Cochlospermum vitifolium were evaluated and they were linked to certain functional properties of industrial interest. The physicochemical parameters were determined by the classic methodology used for carbohydrates and the functional properties, as reported in the literature. The results obtained showed that the gum object of this study is low soluble in water (32.00%), which it corresponds with a relatively high values of swelling index (19.60) and water absorption capacity (77.30%). Also, the high intrinsic viscosity of the C. vitifolium exudate (16.97 dl/g) was related to a high molar mass (8.50 x 10 6 g/mol). These characteristics confer to bototo gum a potential use as a thickener and stabilizer of emulsions. On the other hand, the emulsifying capacity of 84.80 % may be attributed to hydrophobic groups present in its structure (i.e. acetyl and methyl of rhamnose) rather than to the low protein content (0.88%). The gum gels at a minimum concentration, (4.5%), and the mechanism of gelification may be related with interchain crosslinks, established through the divalent cations (predominant in the polymer), which may form junction zones. The C. vitifolium gum exhibits important physicochemical and functional parameters which could serve as a criterion for testing its use in various industries.

“…Phytochemical screening of the bark extract demonstrates the presence of saponins, and anti‐ Scytalidium bioguided fraction shows that triterpenoid saponins were responsible for this activity. Previous phytochemical experimentations of fruit and gum revealed the presence of saponin, polysaccharides and tannins (Abed El Kader et al ., ; De Pinto et al ., ; Hess et al ., ; Rodríguez and Fondevila, ).…”

Screening of the antifungal activities of ten Guadeloupean plants was undertaken to find new extracts and formulations against superficial mycoses such as onychomycosis, athlete's foot, Pityriasis versicolor, as well as the deep fungal infection Pneumocystis pneumonia. For the first time, the CMI of these plant extracts [cyclohexane, ethanol and ethanol/water (1:1, v/v)] was determined against five dermatophytes, five Candida species, Scytalidium dimidiatum, a Malassezia sp. strain and Pneumocystis carinii. Cytotoxicity tests of the most active extracts were also performed on an HaCat keratinocyte cell line. Results suggest that the extracts of Bursera simaruba, Cedrela odorata, Enterolobium cyclocarpum and Pluchea carolinensis have interesting activities and could be good candidates for developing antifungal formulations.
