1. DETERMINATION OF CHEMICAL PROFILE OF Eugenia dysenterica ICE CREAM USING PS-MS AND HS-SPME/GC-MS
The incorporation of Cerrado fruits in food products such as ice cream has many advantages because it represents a source of nutrients and bioactive compounds. Given the demand for less laborious methods to analyze food, the paper spray ionization mass spectrometry technique was applied for the first time for a rapid characterization of the chemical componen

2. Identificação e determinação da atividade antioxidante de carotenoides e antocianinas de frutas / Identification and antioxidant activity determination of carotenoids and anthocyanins from fruits
Considerando a importancia de carotenoides e antocianinas, tanto como pigmentos naturais como pelas suas propriedades antioxidantes, este trabalho foi desenvolvido com o objetivo de avaliar, por meio de cromatografia liquida de alta eficiencia acoplada aos detectores arranjo de diodos e espectrometro de massas (HPLC-DAD-MS/MS), a composicao de carotenoides e

3. Procedimentos analíticos para identificação de antocianinas presentes em extratos naturais
Anthocyanins are among the most important plant pigments. Due to their potential benefits for human health, there is considerable interest in these natural pigments. Nonetheless, there is great difficulty in finding a technique that could provide the identification of structurally similar compounds and estimate the number and concentration of the species pre

4. Optimization of extraction, sterilization and identification of anthocyanins obtained from fruits / Otimização da extração, esterilização e identificação de antocianinas obtidas a partir de frutas
Anthocyanins (ACYS) are natural pigments of plant origin, chemically classified as flavonoids. The industrial use of ACYS is restricted according to some limitations, such as its high cost and relative low stability. In this context, the objective of this study was to use jaboticaba (Myrciaria cauliflora), mulberry (Morus nigra), blackberry (Rubus spp) and j

5. Extraction, purification and isolation of anthcyanins from Syzygium cuminii and evaluation of their biological activities / Extração, purificação e isolamento de antocianinas de jambolão (Syzygium cuminii) e avaliação dos seus efeitos biologicos
Anthocyanins, the natural pigments chiefly responsible for red, blue and purple hues in a great range of flowers and fruit, are used as food dye and pH indicators. Anthocyanins are a member of the family of flavonoids, polyphenolic compounds whose biological properties have been extensively described in literature. Even though anthocyanins are plentiful in n

7. A cytochrome b5 is required for full activity of flavonoid 3′,5′-hydroxylase, a cytochrome P450 involved in the formation of blue flower colors
The substitution pattern of anthocyanin pigments is a main determinant of flower color. Flavonoid 3′,5′-hydroxylase (F3′5′H) is a cytochrome P450 enzyme (Cyt P450) that catalyzes the 3′,5′-hydroxylation of dihydroflavonols, the precursors of purple anthocyanins. Species such as rose and carnation lack F3′5′H activity and are, therefore, unabl

8. Characterization and Functional Identification of a Novel Plant 4,5-Extradiol Dioxygenase Involved in Betalain Pigment Biosynthesis in Portulaca grandiflora
Betalains are pigments that replace anthocyanins in the majority of families of the plant order Caryophyllales. Betalamic acid is the common chromophore of betalains. The key enzyme of the betalain biosynthetic pathway is an extradiol dioxygenase that opens the cyclic ring of dihydroxy-phenylalanine (DOPA) between carbons 4 and 5, thus producing an unstable
