Nutritional reserves of Vochysiaceae seeds: chemical diversity and potential economic uses

Abstract

Contents of proteins, carbohydrates and oil of seeds of 57 individuals of Vochysiaceae, involving one species of Callisthene, six of Qualea, one of Salvertia and eight of Vochysia were determined. The main nutritional reserves of Vochysiaceae seeds are proteins (20% in average) and oils (21.6%). Mean of carbohydrate contents was 5.8%. Callisthene showed the lowest protein content (16.9%), while Q. cordata was the species with the highest content (30% in average). The contents of ethanol soluble carbohydrates were much higher than those of water soluble carbohydrates. Oil contents lay above 20% for most species (30.4% in V. pygmaea and V. pyramidalis seeds). The predominant fatty acids are lauric (Q. grandiflora), oleic (Qualea and Salvertia) or acids with longer carbon chains (Salvertia and a group of Vochysia species). The distribution of Vochysiaceae fatty acids suggests for seeds of some species an exploitation as food sources (predominance of oleic acid), for other species an alternative to cocoa butter (high contents or predominance of stearic acid) or the production of lubricants, surfactants, detergents, cosmetics and plastic (predominance of acids with C 20 or C 22 chains) or biodiesel (predominance of monounsaturated acids). The possibility of exploitation of Vochysiaceae products in a cultivation regimen and in extractive reserves is discussed.

Vochysia rufa Stem Bark Extract Protects Endothelial Cells against High Glucose Damage

“…V. rufa stem bark is rich in carbohydrates, mainly reducing sugars such as inositol, galactose, glucose, mannose, sacarose, arabinose and ribose. Additionally, the presence of polyphenols and triterpenes has been reported in other Vochysia species [ 9 , 11 ]. The in vivo hypoglycemic effect of polysaccharide has been reported for other species such as Coptis chinensis or Taxus cuspidata , where an efficient antidiabetic effect and antioxidant activity on diabetic mice was observed [ 22 , 23 ].…”

“…Vochysia rufa Mart belongs to the Vochysiaceae family and grows as a neotropical tree in Brazil [ 8 ]. The seed of V. rufa is recognized for its nutritional value, due to its content in proteins, sugars, oil and fatty acids, mainly stearic and oleic acids [ 9 ]. Into the seed cell walls, arabinose, galactose and glucose have been shown as the most abundant constituents, followed by mannose and rhamnose.…”

Tratamientos pregerminativos y germinación de semillas de Vochysia lehmannii en los llanos orientales de Colombia

“…El género Vochisya se distribuye desde Mesoamérica hasta el norte de Suramérica (Cordero et al, 2003;Stafleu, 1948), hace parte del orden Polygalales (subclase Rosidae) y es uno de los siete géneros con amplia distribución tropical (Mabberley, 2017). Por su arquitectura y floración de color amarillo intenso tiene usos ornamentales y la madera se utiliza para construcción (Williams, 2005), las semillas presentan uso alimenticio y son procesadas como sustituto a la manteca de cacao (Mayworm et al, 2011). Además, las especies del género Vochysia guardan similitud en cuanto a su morfología floral (Oliveira y Gibbs, 1994) y en las características cualitativas y cuantitativas de la madera (Williams, 2005), sus semillas pueden ser deshidratadas hasta 6.4 % (Salazar y Vázquez, 1999), es decir, son semillas intermedias (Ellis et al, 1990;Hong et al, 1996), y alcanzan porcentajes de germinación arriba de 80 % (Blanche et al, 1991;Kleber et al, 2018) con tendencia a la asincronía.…”

Composição química dos grãos e da cera foliar de variedade Glycine max (L.) Merrill cv. MG/ BR-46 Conquista cultivada sob atmosfera enriquecida de gás carbônico e temperatura elevada

“…Mayworm & Salatino (1996a, b) determinaram o teor e distribuição dos ácidos graxos de espécies da Caatinga e do Cerrado, na busca de novas fontes de sementes oleaginosas potencialmente econômicas. Sementes de Vochysiaceae nativas do Brasil também revelaram potencial como fontes de óleo para diversas aplicações (Mayworm et al, 2011).…”
