Sustainable management and use of a medicinal emblematic plant in Chile: Buddleja globosa Hope
Provedor de dados: 85
Autores: Wilckens,P; Fernández,MP; Gómez,M; Peña,I; Montenegro,G.
Buddleja globosa Hope is a well-known native, medicinal plant because of its digestive and cicatrizing properties. Due to the increasing domestic and international demand, B. globosa abundance and distribution in Chile has resulted in the intensive exploitation of the plant's natural habitat, without consideration of the plant's regenerative capacity. The main objective of this research was to establish the B. globosa growth cycle and model its regeneration cycle. This would allow for more productive, efficient and sustainable use and management of this species, thus ensuring its long-term conservation. We selected two study sites, one wild and another one cultivated. In each one, ten individuals were marked as control treatments, for further observations,...

Antioxidant and bacteriostatic effects of the addition of extract of quillay polyphenols (Quillaja saponaria) in the marinade of broiler chicken
Provedor de dados: 89
Autores: Fellenberg,MA; Espinoza,A; Peña,I; Alarcón,J.
The nutritional and sensorial characteristics of chicken meat can be affected by oxidative rancidity, process of oxidation of lipids in the meat that constitutes one of the main forms of food deterioration. This problem may be prevented or reduced by adding antioxidants to the meat during the process of marination. In the present study, the addition of a polyphenol-rich quillay extract (QLPerm®) at 5 levels (0, 0.05, 0.10, 0.15, and 0.20%) to the marinade of chicken meat was evaluated. The marinated meat was stored under refrigeration (6 ºC) for 0, 2, 4, 6, and 8 days. Basal and induced lipid oxidation was evaluated by TBARS analysis. Microbiological quality was assessed by total coliforms and mesophillic aerobe counts. The application of this natural...

Effect of dried extract of boldo (Peumus Boldus Mol.) on growth and oxidative tissue status of broiler chickens
Provedor de dados: 89
Autores: Fellenberg,MA; Delporte,C; Backhouse,N; Peña,I; Speisky,H.
The addition of antioxidants to broiler diets has been shown to enhance their antioxidant status. Since boldo (Peumus boldus Mol.) leaves contain highly antioxidant molecules, a dried extract of boldo (DEB) was added to broiler diets to improve "in vivo" antioxidant tissue status and to favor animal growth. A DEB standardized for antioxidant content was prepared and added to poultry diets at three different levels (low-DELB, medium-DEMB, and high-DEHB) for a period of 6 weeks. A single negative control (no added antioxidant) and one positive control (supplementation with 200 mg/kg vitamin E) were used. Plasma antioxidant capacity (PAC), thiol content (GHS), and basal and induced lipoperoxidation of liver, leg and breast tissues were determined in birds at...
