| A erva-de-São-João é uma planta medicinal empregada no tratamento antidepressivo. A hipericina é considerada um dos compostos que contribui para o efeito medicinal da planta. Uma vez que a concentração e a quantidade do princípio ativo pode ser afetada pela nutrição das plantas, este trabalho teve por objetivo avaliar os efeitos do pH do solo e da adubação fosfatada sobre o crescimento inicial e a produção de hipericina em erva-de-São-João. O experimento foi realizado em Lages, SC, de julho a dezembro de 2003, em casa de vegetação. Utilizou-se delineamento experimental inteiramente casualizado (fatorial 4 x 3), correspondendo a quatro valores de pH (4,1; 5,5; 6,0 e 6,5) e três doses de P (0, 50 e 100 mg kg-1 de solo), com quatro repetições. Foram... |

| Abstract This research was carried out to evaluate centesimal [dry matter (DM), ash, and crude contents of proteins (CP), fats (CFt) and fiber (CFb)] and mineral composition (Ca, Mg, N, P, K, Fe, Zn, Cu and Mn) of peel and flesh tissues of feijoa fruit (cultivars Alcântara, Mattos, Helena and Nonante, and accession 2316). The genotypes had, in the flesh, DM of 12.10-15.40%, ash of 0.33-0.40%, CP of 0.95-1.45%, CFt of 0.56-1.72%, and CFb of 1.39-2.43%, and in the peel DM of 12.8-17.27%, ash of 0.30-1.49%, CP of 0.56-0.88%, CFt of 0.57-0.90%, and CFb of 2.54-3.98%. The contents of Ca, Mg, K, N and P in the peel were 96-116, 20-30, 1588-3635, 1096-1643 and 68-83 mg kg-1 FW, respectively, and in the flesh were 56-92, 17-29, 1358-2917, 2017-3384 and 255-374 mg... |

| Abstract: The objective of this work was to evaluate the physicochemical attributes and vitamin C contents of fruits of five Brazilian genotypes of feijoa (Acca sellowiana), at harvest and after cold storage. The Alcântara, Mattos, Helena, and Nonante cultivars, as well as accession 2316, were studied. The assessed attributes were: fresh mass loss, titratable acidity, soluble solids contents, soluble solids contents/titratable acidity ratio, pH, skin and flesh color, texture, and vitamin C contents (skin and flesh). After storage, there were reductions of 2.9% in soluble solids contents, of 32.2% in titratable acidity, and of approximately 85% in texture attributes, besides increases of 36.3% in the soluble solids contents/titratable acidity ratio and of... |

| Abstract: The objective of this work was to quantify the total phenolic content (TPC) and total antioxidant activity (TAA) of fruit from Brazilian genotypes of feijoa (Acca sellowiana). Skin and flesh tissues of the fruit were evaluated for the Alcântara, Helena, Mattos, and Nonante cultivars, and for the 2316 accession. TPC and TAA were both assessed in aqueous and hydroalcoholic extracts, and TAA was assayed by the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS [2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)] methods. The TPC values, for aqueous extracts of the skin and flesh tissues, were 114.9 and 88.3 mg gallic acid equivalent (GAE) per 100 g fresh weight (FW), respectively. The corresponding values for TAA determined by the DPPH method, the... |

| Abstract: The objective of this work was to characterize entire flowers of the feijoa (Acca sellowiana) genotypes 'Alcântara', 'Helena', 'Mattos', 'Nonante', and the accession 2316 for dry matter, total antioxidant activity (TAA), and the contents of soluble solids, ascorbic acid, total anthocyanins, total flavonoids, and total phenolic compounds (TPC), as well as for the petal surface areas and colors. The TAA was quantified by the ABTS and DPPH methods. Flowers of the accession 2316 and of the cultivars Alcântara and Helena showed the highest contents of anthocyanins and flavonoids, as well as the highest values of TPC and TAA. The feijoa genotypes cultivated in Southern Brazil show high contents of soluble solids and represent a natural source of... |
