“…catechins and procyanidins (Monties, 1968;Oleszeck et al, 1988). Other classes such as flavonols (Monties, 1968;Teuber and Herrmann, 1978;Dick et al, 1987) and dihydrochalcones have been found. In the latter case, phloridzin and phloretin-xyloglucoside have been identified (Oleszek et al, 1988).…”

Phenolic compounds and polyphenol oxidase (PPO) activity in the fruits of 11 apple cultivars before and after bruising were studied in relation to their susceptibility to browning. The degree of browning has been determined by the simultaneous measurements of soluble (absorbance at 400 nm) and insoluble (lightness) brown pigments. The sum of these two expressing the extent of browning, closely correlated with the amount of phenolics (hydroxycinnamic derivatives and flavan-3-01s) degraded. Maturity did not appear to greatly influence the development of browning.

“…1,2 Previous papers have reported on the chemical composition of apple varieties from the USA and from Europe, identifying the main components as esters of caffeic and coumaric acids, procyanidines and flavonols (quercetin glycosylated derivatives). [3][4][5][6][7][8][9][10] In recent years, an increasing number of publications have reported the chemistry of flavonols, especially in view of their biological (antibacterial, antiviral, anti-inflammatory, anti-allergic, anti-trombotic, vasodilatory, anti-mutagenic and neoplastic) properties and their ability to protect against or inhibit the development of cancer when consumed on a regular basis. 11 Notwithstanding the data available from apple samples cultivated in the Northern hemisphere, it must be pointed out that the production of flavonols may vary in response to different environmental conditions.…”

Este trabalho apresenta a primeira investigação sobre a estrutura química dos flavonóis presentes em cascas das três variedades de maçãs mais cultivadas no Brasil: Gala, Golden e Fuji. As análises foram feitas por CL/UV/EM (cromatografia líquida de alta eficiência com detector UV com arranjo de diodos acoplada à espectrometria de massas), usando adição pós-coluna de reagentes de deslocamento de UV e também espectrometria de massas de múltiplos estágios (EM n ) com ionização "electrospray" no modo negativo. A identificação "on-line" com base nos dados de CL/UV/EM demonstrou a presença de rutina, hiperosídeo, isoquercitrina, quercitrina e outros três derivados de quercetina-3-O-pentosídeo. As análises por CL/UV/EM também demonstraram que as três variedades de maçã têm perfis cromatográficos semelhantes.This work describes the first detailed investigation into the chemical structures of flavonols present in the three apple varieties most commonly cultivated in Brazil: Gala, Golden and Fuji. The analyses were carried out by LC/UV/MS (high-performance liquid chromatography coupled to diode array UV detection and mass spectrometry), using post-column addition of UV shift reagents, as well as multiple stage mass spectrometry (MS n ) with electrospray ionization in the negative ion mode. Rutin, hyperoside, isoquercitrin, quercitrin, quercetin and three other quercetin-3-pentoside derivatives were identified through the characterization of on-line-based LC/UV/MS data. LC/UV/MS analysis also revealed that the three apple cultivars have similar chromatographic profiles. Keywords: apple, flavonols, LC/UV/MS, UV shift reagents IntroductionApple (Malus domestica Borkh., Rosaceae) cultivation stands out as an important and rapidly growing market segment in Brazil. While a few traditional apple varieties have been locally grown, such as Rainha, Soberana and Brazil varieties, other varieties such as Gala, Golden and Fuji have proved superior in terms of growth and productivity, particularly in Brazil's southern and central regions. 1,2 Previous papers have reported on the chemical composition of apple varieties from the USA and from Europe, identifying the main components as esters of caffeic and coumaric acids, procyanidines and flavonols (quercetin glycosylated derivatives).

Objective: M. floribunda is an ornamental and landscape plant in Turkey and it's small fruits are consumed as food. Antimicrobial, antioxidant activities and phytochemical contents of M. floribunda were investigated. Material and Method: M. floribunda was collected from different localities in the province of Elazig-Turkey. The nutritive value (flavonoid, sugar, fatty acid, vitamin, protein, element), antioxidant (lipid peroxidation, glutathione amounts and DPPH) and antimicrobial activities (on thirteen bacteria, three yeast and two dermatophyte) of M. floribunda were determined. Results: Vitamin (1.73-3.5 µg/g A, 1.32-1.44 µg/g D, 2.75-2.83 µg/g E, 2.64-3.30 µg/g K), flavonoid (33-253 µg/g routine, 93-123 µg/g morin, 0.22-0.32 µg/g quercetin, 292-356 µg/g naringenin), sugar (97-820 µg/g), protein (1.4-1.6 µg/g) and phytosterol (0.27-1.74 µg/g ergosterol, 26-36 µg/g stigmasterol, 95-121 µg/g β-sitosterol and 0.21-0.35 µg/g retinol) levels can vary. In vitro medium, it is determined that in FeCl group, LPO amounts increases in a large ration with respect to the control group and LPO levels in groups which includes plant extracts and FeCl 2 , decreases in certain amounts. It was determined that the radical scavenging activity of the fruits increased due to the dose. Four different fatty acids were identified in the fruit. Fruits were found to different levels of sugar. Vitamin E in the examples were determined high rate. Protein found up to 1.686 mg/g. Ca content was the most detected in the all samples. Extracts inhibited the development of microorganisms at different rates. Conclusion Although studies on this type were limited, similarities and differences were seen in the results compared to other studies.
