“…The EG spectrum showed bands similar to standard galactomannans. The result agreed with those reported by Andrade et al (1999) and Azero and Andrade (2002). The spectra of the purified and cross-linked gum showed differences in the bands in some spectral regions.…”

“…The main difference between galactomannans is their mannose to galactose ratio (M/G) and the sequential distribution of galactopyranosyl substituents on the mannopyranosyl backbone. In C. pulcherrima endospermic gum, the M/G ratio is 2.8 (Andrade et al, 1999), but the sequential distribution of the galactopyranosyl unit is unclear. C. pulcherrima, a small tree known, as Pride of Barbados, "flamboianzinho", "flaboiant mirim", "barba de barata" and "brado de estudante", is widely used in many countries in popular medicine, showing many properties, including its use as an emmenagogue, antihemorrhagic agent and abortifacient and also in the treatment of infections (Alanis et al, 2005, Chiang et al, 2003, Patil et al, 1997.…”

“…When the same numerical values of the shear rate (γ • ) and frequency (ω) are considered, the γ • dependence of the viscosity (η) and the ω dependence of the complex viscosity (η*) are closely superimposable for both galactomannan solutions, which means that the Cox-Merz rule was satisfactorily followed, 24 as previously observed for other galactomannans from non-conventional sources. 25 The effect of the addition of the PJ galactomannan to κ-carrageenan solutions was investigated. The κ-carrageenan sample was obtained from Hypnea musciformis and purified as the sodium salt form.…”

A galactomanana de Prosopis juliflora (PJ) foi obtida por extração em água, a 50 °C, a partir de sementes moídas. As suas características estruturais e as propriedades em solução foram comparadas com as de uma amostra comercial de goma guar (GG). Após degradação parcial, as amostras resultantes foram submetidas à espectroscopia de 13 C RMN. As razões manose/galactose de PJ (M/G = 1,64) e de GG (M/G = 1,85) foram determinadas a partir das áreas relativas aos picos atribuídos a C-1. A expansão das linhas do C-4 revelaram diferenças na estrutura fina das duas galactomananas. A viscosidade intrínseca determinada para a amostra de GG, [η] = 10,3 dL g -1 , foi ligeiramente maior do que a determinada para a PJ, [η] = 9,4 dL g -1 . Experimentos dinâmicos realizados nas mesmas concentrações mostraram comportamentos viscoelásticos similares para as duas gomas. Nenhum aumento no módulo de armazenamento (G′) foi observado para misturas κ-carragenana/PJ em 0,1 mol L -1 KCl em uma concentração total de 1,0 g L -1 , em relação à κ-carragenana sozinha. Géis fortes, obtidos pela mistura de κ-carragenana e PJ ou GG em 0,25 mol L -1 KCl em uma concentração total de 10 g L -1 apresentaram propriedades mecânicas similares.The galactomannan from Prosopis juliflora (PJ galactomannan) was extracted from milled seeds in water at 50 o C. Its structural and solution properties were characterised in comparison with a commercial sample of guar gum (GG galactomannan). After partial degradation, the resulting samples were submitted to 13 C-NMR spectroscopy. The mannose to galactose (M/G) ratios of PJ (M/G = 1.64) and GG (M/G = 1.85) galactomannans were estimated from the relative peak areas of the corresponding C-1 lines. Expansion of the C-4 lines revealed differences in the fine structure of the two galactomannans. The intrinsic viscosity determined for the GG sample, [η] = 10.3 dL g -1 , was slightly higher than that determined for PJ galactomannan, [η] = 9.4 dL g -1 . Dynamic experiments carried out at the same concentrations showed similar viscoelastic behaviours for the two gums. No enhancement in the storage modulus (G′) was observed for κ-carrageenan/PJ mixed solution in 0.1 mol L -1 KCl at 1.0 g L -1 total polymer concentration, in relation to κ-carrageenan alone. Self-supporting gels obtained by mixing κ-carrageenan and PJ or GG galactomannans in 0.25 mol L -1 KCl at 10 g L -1 total polymer concentration displayed similar mechanical properties.

“…[26] The galactomannans is obtained from the seeds of Caesalpinia pulcherrima and Cassia javanica. [27] The presence of galactomannans (<1%) significantly improved the freezethaw stability and increase in the gelatinization temperature. [28] Locust bean gum and GG mixing in sago starch increase thermal and rheological properties.…”

The present review explains nutritional, therapeutic, and pharmaceutical potential of plant gum that is commonly applied to water-soluble, non-starch polysaccharides of commerce. This article also emphasizes commercial and domestic uses of important products of gum such as chicle and jelutong mainly non-elastic gums or chewing gums. These are also used in food, pharmaceutical, paper textile, and other industries. The present review also explains various biological activities such as antidiarrheic, antitumor, anti-inflammatory, anti-arthritic, antiparasitic, gastrourinary, antitumor, antiparasitic, antioxidant, chemopreventive, and gastroprotective activity of plant gums. These reduce stomach inflammation, system cleansing or to settle the intestines. Other uses for mesquite gum include treatment for lice, sore throat, cough, laryngitis, fever reduction, painful gums, and hemorrhoids and it can be used as a purgative. Gum arabic is a water-soluble dietary fiber rich in Ca , and decreases plasma phosphate concentration as well as urinary excretion of phosphate and Na + . Gums are used as adhesives, crystallization inhibitors, emulsifying agents, emulsion stabilizers, encapsulating agents, film formers, foam stabilizers, suspending agents, suspension stabilizers, or syneresis inhibitors and impart other specific properties. The gum is also used to a limited extent in polishes, contact insecticides and pesticides, photographic emulsions, and pharmaceuticals. This article suggests wider use of plant gums in generation of drug delivery system for cancer and brain tumor therapy. There is no doubt that chemical constituents of plant gums can be largely used for making therapeutic drugs because of their broadspectrum biological effectiveness.
