Classes of secondary metabolites identified in three legume species R. Bras. Zootec.
Nepomuceno,Delci de Deus; Almeida,João Carlos de Carvalho; Carvalho,Mário Geraldo de; Fernandes,Renata Duarte; Catunda Júnior,Francisco Eduardo Aragão.
The objective of this study was to identify secondary metabolite classes of tropical kudzu, perennial soybean and archer legumes through identification by phytochemical screening and confirmation by infrared (IR), ¹H and carbon-13 NMR spectroscopy of fractions obtained by organic solvents partition of crude extracts. These analyses allowed for proposing the presence of the following metabolite classes: reducing sugars, saccharides, saponins, cardiac glucosides, terpenes, coumarins, tannins, alkaloids and flavonoids. The tannins, saponins, alkaloids, organic acids and flavonoids had special consideration because they are toxic compounds and can affect the animal metabolism.

Dry matter production and chemical composition of tropical forage legumes under different shading levels Animal Sciences
Almeida, João Carlos de Carvalho; Morais, Leonardo Fiusa de; Araújo, Raphael Pavesi; Morenz, Mirton José Frota; Abreu, João Batista Rodrigues de; Soares, Felipe Almeida.
This study aimed to evaluate the shading influence on production and qualitative traits of four tropical forage legumes (calopo, puero, archer and perennial soybean). Legumes were cultivated under levels of artificial shading (0; 30; 50 and 70%) from January 2006 to June 2007. Dry matter production (DM), crude protein (CP), neutral detergent fiber (NDF), cellulose (CEL), hemicellulose (HEM) and lignin contents were evaluated. In the summer, increases in legumes DM yield were observed when grown under increasing shading levels. Calopo, puero, and archer production showed quadratic effect. Regression analysis derivation for dry matter yield showed levels of maximum values at 35.0; 33.78 and 45.45% in the summer and 34.94; 34.83 and 33.29% in the fall....
