1. Phenolic content and antioxidant activity of parts of Passiflora edulis as a function of plant developmental stage
ABSTRACT Passiflora edulis Sims var. flavicarpa O. Deg. (Yellow-passion fruit) is the native plant species most used by juice industries in Brazil while its leaf extracts are widely employed in folk medicine. This study evaluated the phenolic content of leaves, roots, fruit shells and pulp of plants of P. edulis in juvenile, flowering and fruiting stages. Th

3. Fruit sphere microenvironments and berry phenolic content of Cabernet Sauvignon (Vitis vinifera L.) cultivated under rain-shelter systems with coloured plastic film
Abstract Rain-shelter cultivation has been proven an important cultivation method for grape-plantings in continental monsoon climate zones, of which white plastic films are the most common shelter material. However, while this method and material reduces the occurrence of the disease, it can also decrease the grape berry quality. Five colours (including red,

4. Quality of 'Delta Valencia' orange grown in semiarid climate and stored under refrigeration after coating with wax
The effects of carnauba-based wax on the quality of 'Delta Valencia' orange produced in Ceará state, Brazil, were studied. The fruits were coated with carnauba-based wax and refrigerated (7 ± 2 ºC and 85 ± 2% R.H.) for 28 days. The quality attribute parameters assessed were weight loss, peel color (brightness, hue angle, and chromaticity), peel moisture,

7. Potencial de utilizaÃÃo de frutos de genÃtipos de muricizeiros cultivados no litoral do Cearà / Potential use of fruits cultivated genotypes muricizeiros the coast of Ceara
The objective of this work was to evaluate fruits of nance (Byrsonima dealbata), from different genotypes, by means of the physical and physical-chemical characterization. Fruits of nance were collected of from genotypes of the three experimental station of EMBRAPA - Empresa Brasileira de Pesquisa AgropecuÃria, in CearÃ, Brazil. Eighteen genotypes of nance

8. Carotenoides e compostos bioativos : relação com propriedades anti-radical livre e corante em frutas tropicais / Carotenoids and bioactive compounds : relationship between free radical scavenger properties and color in tropical fruits
The increased demand for high life quality has been associated to healthy food, increasing the industry interest for functional foods, which are defined as any food or bioactive compounds with potential to be benefic for the consumer health. The bioactive compounds found in foods, such as carotenoids, phenolic compounds and ascorbic acid (AA) are involved wi

9. Qualidade e atividade antioxidante total de pedÃnculos de clones comerciais de cajueiro anÃo precoce / Quality and activity total antioxidant capacity of penduncles of commercial grain stalks of clones of dwarf cashew apple tree.
Cashew has big importance in Brazilian culture of fruits, principally in Northwest region, presenting very expressive social and economic activity. Accordingly to some studies cashew apple has a high vitamin C, carotenoids and phenolics compounds contents. More than vitaminic potential, these compounds have antioxidant potential to cashew pulps.

10. Attractive and defensive functions of the ultraviolet pigments of a flower (Hypericum calycinum)
The flower of Hypericum calycinum, which appears uniformly yellow to humans, bears a UV pattern, presumably visible to insects. Two categories of pigments, flavonoids and dearomatized isoprenylated phloroglucinols (DIPs), are responsible for the UV demarcations of this flower. Flavonoids had been shown previously to function as floral UV pigments, but DIPs h

11. Structural analysis, plastid localization, and expression of the biotin carboxylase subunit of acetyl-coenzyme A carboxylase from tobacco.
Acetyl-coenzyme A carboxylase (ACCase, EC 6.4.1.2) catalyzes the synthesis of malonyl-coenzyme A, which is utilized in the plastid for de novo fatty acid synthesis and outside the plastid for a variety of reactions, including the synthesis of very long chain fatty acids and flavonoids. Recent evidence for both multifunctional and multisubunit ACCase isozymes

12. Pigmented Soybean (Glycine max) Seed Coats Accumulate Proanthocyanidins during Development.
The dominant I gene inhibits accumulation of anthocyanin pigments in the epidermal layer of soybean (Glycine max) seed coats. Seed-coat color is also influenced by the R locus and by the pubescence color alleles (T, tawny; t, gray). Protein and RNA from cultivars with black (i,R,T) and brown (i,r,T) seed coats are difficult to extract. To determine the natur
