“…Para el inicio de las pruebas fitoquímicas y de actividad biológica, se procedió a utilizar el extracto metanólico para los estudios biodirigdos fitoquímicos ya que de acuerdo con un trabajo llevado a cabo por Mora et al (2021), los extractos metanólicos de semillas de ambas especies vegetales, presentaron mayores rendimientos comparados con los demás solventes de extracción: L. leucocephala: metanol: 5.29% > hexano: 1.95% > acetona: 0.67%; L. esculenta: metanol: 4.32% > hexano: 4.28% > acetona: 0.64%. El presente trabajo corrobora que los valores más elevados, corresponden a los extractos, particiones y fracciones metanólicas y acuosas de ambas especies de Leucanea (Tabla N° 2 y Tabla N° 3), lo que sugiere que la mayoría de los metabolitos contenidos en estas plantas y sobre todo en las semillas son de naturaleza polar, como fenoles, taninos o saponinas, entre otros; seguido de metabolitos primarios como lípidos asociados a tejidos de reserva y afines a solventes no polares como el hexano (Román-Cortés, 2014). Trabajos realizados por Savita y Preeti, (2015) con tres extractos diferentes de hojas de L. leucocephala Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas / 666 reportaron que el extracto metanólico tuvo el rendimiento más elevado de 2.43% en comparación con los extractos obtenidos con acetona y cloroformo (1.05 y 0.96% respectivamente), por su parte Mora-Villa, (2017) reportó rendimientos de los extractos crudos de semillas con valores similares a los obtenidos: L. leucocephala: metanol: 4.34% > hexano: 2.04% > acetona: 0.53%; L. esculenta: hexano: 5.09% > metanol: 4.23% > acetona: 0.63%.…”

Phytochemical bio-guided studies are used to find compounds with biological activity. Flavonoids from seeds of Leucaenaspecies have antimicrobial activity in strains of medical interest, therefore, fresh seeds were collected from the town of Tlayacapan, Morelos, Mexico. The methanolic extracts were obtained by the maceration technique, targeted fractionation was performed using adsorption and molecular exclusion chromatographic techniques; to observe the antimicrobial activity, agardiffusion techniques were used; spectrometric and spectroscopic techniques were used for the characterization of D-pinitol, resulting from the fractionation of L. leucocephala. Antimicrobial activity was found on strains of Escherichia coliCUSI and Staphylococcus aureusATCC 29213 of the most polar fractions, identifying the responsible compounds by HPLC: caffeic acid, gallic acid, p-coumaric acid, quercetin, catechin and apigenin, these compounds can inhibit the activation enzymatic, synthesis of nucleicacids and proteins, chelating with different ions, etc.

“…They make up 50% of the dry weight of the seed (Ter Meulen et al, 1979;Middelbos and Fahey, 2008;Ahmed and Abdelati, 2009). In leucaena seeds, the carbohydrate concentration ranges from 35-60%, Table 1 (Sethi and Kulkarni, 1995;Román-Cortés et al, 2014) and the metabolic conversion rate in animal models range from 10.7 to 12.4 kilojoule per gram on a dry basis, kj g db -1…”

“…In Mexico, the seeds of various species are consumed, especially Leucaena esculenta and Leucaena leucocephala. Protein concentration of these species varies from 26 to 31%, while the carbohydrate concentration range is 57 to 61% (Román-Cortés et al, 2014). Additionally, the seeds contain some non-polar vitamins, as well as compounds of phenolic origin that can exert a biological function such as nutraceuticals or probiotics (Román-Cortés et al, 2014).…”

“…The tannins, trypsin inhibitors, phytic acid, tannins, oligosaccharides and mimosine have been reported as unwanted/anti-nutritive compounds in leucaena seeds. The biological effect of those anti-nutritive molecules directly affects the digestibility of protein and carbohydrates (Román-Cortés et al, 2014;Tran et al, 2016). The non-protein amino acid called mimosine, acid (S)-α-Amino-β-[1-(3-hydroxy-4oxopyridin), inhibits some intracellular processes (Tran et al, 2016;Chaichun et al, 2019) and can be used as an immunosuppressive, antiarrhythmic and hypocholesterolemic agent (Syamsudin et al, 2010).…”

The consumption of legume seeds has benefits for human nutrition and health. Seeds of Leucaena leucocephala and Leucaena esculenta are fast-growing legumes that are used for a variety of purposes. In general, they are used to preserve/restore the soil; the foliage can be used as fodder for livestock and the seeds for human consumption in rural populations. Leucaena seeds are a source of nutrition, since they contain proteins, carbohydrates and lipids (including omega 3, 6 and 9 unsaturated acids). The protein fraction has shown pharmaceutical effects of interest (analgesic, lipolytic, emollient, anticancer, anti-inflammatory, anti-coagulant and anti-diabetic) and some techno-functional properties for the food industry. However, the main limitation to the human consumption of leucaena seeds is the presence of mimosine, an antinutrient that produces side effects such as alopecia, growth retardation, cataracts and infertility in animals. In this sense, some technological processes that could contribute to its decrease. This work was carried out at the Nutraceuticals Department of the Interdisciplinary Research Center for Integral Regional Development, Oaxaca Unit, Mexico. A comprehensive and integrative review of research work carried out in different parts of the world was conducted. The bibliographic search was carried out from January 2020 to January 2022. Several databases such as Scopus, Latindex, Dialnet, Redalyc.org, FAO and Academic Google were explored. A total of 81 documents were used to prepare this review document. This review integrates aspects related to the potential use of leucaena seeds in human nutrition: nutritional composition, pharmacological, techno-functional properties, the processes to improve digestibility and reduce toxicity.

“…Galactomannan edible coatings (konjac, Cassia grandis and Gleditsia triacanthos), as well as guar and locust bean gum, have been used for food and agricultural applications (Mikkonen, et al, 2010;Vox, et al, 2013;Albuquerque, et al, 2017). Leucaena leucocephala (guaje), a legume native from Mexico, belongs to family Fabaceae (Ferreira, et al, 2016;Mittal, et al, 2016) and it is rich mainly in protein (31,70%) and carbohydrates (61,31%) (Román-Cortés, et al, 2014;Almeida Filho, et al, 2016). The principal carbohydrate fraction is the soluble fiber galactomannan, which is formed by linear chains of β-(1-4)-D-mannose units substituted by single α-D-galactose units at O-6 (Ferreira, et al, 2016;Mittal, et al, 2016).…”

Biopolymers are useful in the industry due to its elastic properties and sustainability as replacements of non-renewable polymers. In this article, bioplastics were produced and characterized using chitosan (CH), sodium alginate (SA), and galactomannan (GAL) from insects (Hermetia illucens), brown algae (Macrocystis pyrifera) and seeds (Leucaena leucocephala), respectively. The structure of biopolymers was observed by infrared spectroscopy (FTIR) and characterized by viscosity at different concentrations. The developed bioplastics were characterized by color and mechanical properties (texture). The results were compared to standard samples (commercial). The FTIR spectra confirmed the presence of the typical structure (footprint) for the obtained polymers. The SA showed significantly higher viscosity for all concentrations compared to the standard and the other polymers. The bioplastics strength was similar among CH, SA and GAL for all concentrations; only SA (0,5%) demonstrated higher strength than the standard. For color measurements, hue value indicated a red-yellowish color and the chrome increased directly proportional with polymer concentration. The observed properties suggest that these sustainable sources might be an alternative to bioplastic production, which can be extended to functionalization and molecular interactions for broad applications in different industries.
