“…Entre os alimentos em estudo cita-se o arroz, no qual a maior atividade antioxidante está presente em grãos integrais devido à concentração de polifenóis encontrados na casca do arroz (Paucar-Menacho et al, 2007;Quagliariello et al, 2016 (Zhang et al, 2015;Thammapat et al, 2016).…”

“…As cultivares brasileiras e italianas analisadas demonstraram que o arroz integral contém cerca de 10% da casca e aproximadamente 2,5% de óleo, importante do ponto de vista nutricional e funcional, o que o torna mais atrativo quando comparado ao arroz branco e o parboilizado, cujo processo retém oligoelementos ao migrar para o interior do arroz, porém não permite manter as substâncias lipossolúveis, como os tocoferóis e o γ-orizanol, devido à influência do binômio tempo e temperatura do processo (Kim et al, 2007;Walter, M., Marchesan, E., 2011;Oluremi et al, 2013;Zhang et al, 2015).

“…Os resultados obtidos para ambos os extratos apontam a influência dos processos industriais sobre a atividade antioxidante do arroz (Walter, M., Marchesan, E, 2011;Zhang et al, 2015 Este método apesar de ser amplamente utilizado por diversos autores para avaliar a capacidade antioxidante do extrato metanólico das amostras analisadas tem como princípio a inibição do radical estável 2,2-difenil-1-picrilidrazil (DPPH•) pelos antioxidantes (Moon, Shibamoto, 2009;Scherer, Godoy, 2009;Deng et al, 2011;Kedare, Singh, 2011) .…”

ESTUDO DOS ÁCIDOS GRAXOS E DAS PROPRIEDADES ANTIOXIDANTES DE ARROZ (Oryza sativa L.) BRUTO, INTEGRAL, PARBOILIZADO E BRANCO COMERCIALIZADOS NO BRASIL E NA ITÁLIA

Resumo: O arroz destaca-se como o cereal de maior consumo no mundo por ser fonte de vitaminas, minerais, fibras, compostos bioativos e ácidos graxos insaturados. Partindo deste pressuposto o objetivo deste trabalho foi estudar e quantificar os ácidos graxos, polifenóis totais e a capacidade antioxidante total com os métodos DPPH• (extrato metanólico) e com fotoluminescência (extrato metanólico e lipídico) de amostras de arroz bruto, integral, parboilizado e branco comercializado no sul do Brasil (Vale do Itajaí) e na região do Vale do Pó, no norte da Itália. Os resultados deste trabalho demonstraram que 95% do conteúdo de lipídios totais, nas respectivas tipologias de arroz de ambos os países, é representada pelo ácido palmítico, oleico e linoleico. Em relação ao conteúdo de polifenóis totais, o valor médio máximo obtido foi 477 g Eq

“…Традиционные чернозерные сорта имеют мелкое зерно и более низкую урожайность по сравнению с белозерными. Поэтому при создании новых сортов риса селекционеры стремились преодолеть эти недостатки, скрещивая образ-цы риса с окрашенным перикарпом зерна и белозерные сорта с высокими показателями хозяйственно ценных признаков (Maeda et al, 2014;Zhang et al, 2015;Рысбекова и др., 2017).…”

Genetic Resources of Rice (Oryza Sativa L.) With Colored Pericarp

The rice plant (Oryza sativa L.) provides nutrition for more than half the world's population. Traditionally it is considered an Asian crop, but it is also cultivated in Africa, America, Australia and Southern Europe. The main areas of rice growing in the world are occupied with the white-grained varieties. Wild-growing ancestors of cultural rice had a colored grain pericarp. In the countries of traditional rice growing, along with white-grained varieties, red and black grain rice varieties are grown as a dietary and therapeutic product. It is used for food without preliminary grinding of the grains, therefore all nutrients and biologically active substances this culture is valued for are preserved. Rice with the colored grain pericarp has a higher antioxidant activity than white-grained. The review presents data on the content of antioxidant compounds in the varieties of the red-and black-grained rice: phenolic acids, flavonoids, γ-oryzanol, anthocyanins, proanthocyanidins, etc. Aiming at these useful properties of rice plants with a colored grain pericarp, the leading rice-growing countries work on breeding of the modern pigmented rice varieties. In European countries, Italy and France, the red and black grain varieties of rice with a high content of phytochemical elements have also been bred based on Asian varieties. Breeding of rice varieties with colored grain pericarp was started in the Russian Federation in 2001. As a result, the following rice varieties were developed: red-grained Mars and Rubin (2012), as well as the black-grained glutinous variety Yuzhnaya Noch (2014), which are included in the RF State Register of Protected Breeding Achievements. These varieties have been revealed to contain a large amount of oleic and linolenic acids (up to 43 % each), whereas only their traces are found in the white-grained rice variety Rapan. There are significant differences in the content of antioxidants: Rapan has 7 mg/100 g; Mars and Rubin, 45 mg/100 g; Yuzhnaya Noch, 105 mg/100 g. These varieties have been introduced into commercial production and are used for dietary nutrition and as a starting material for the creation of new exclusive varieties of rice.Key words: red rice; black rice; rice varieties; hybridization; breeding; antioxidants; anthocyanins; proanthocyanidins; nutritional value.Рис посевной (Oryza sativa L.) обеспечивает питание более полови ны населения Земли. Традиционно он считается азиат-ской культу рой, но возделывается также в Африке, Америке, Австралии и Южной Европе. Основные площади посева риса в странах мира занимают белозерные сорта. Дикорастущие предки культурного риса имели окрашенный перикарп зерна. В странах традиционного рисоводства наряду с белозерными сортами выращивают крас нозерный и чернозерный рис для использования в качестве дие тического и лечебного продукта. Его употребляют в пищу без предварительного шлифования крупы, поэтому сохраняются все питательные и биологически активные вещества, которыми ценит ся эта культура.

Cimicifugae Rhizoma (sheng ma) is a well-known traditional Chinese medicine, which has been demonstrated to possess anti-inflammatory, antipyretic and analgesic activities. In the present study, a simple and efficient HPLC-DAD (high-performance liquid chromatography coupled with diode array detection) method was developed and validated for simultaneous quantification of 19 chemical components (including 16 phenolic acids, one coumarin and two alkaloids) in Cimicifugae Rhizoma. The result indicated that this method could effectively evaluate the quality of Cimicifugae Rhizoma and provide a valuable reference for further study. Additionally, the antioxidant activity of Cimicifugae Rhizoma was evaluated by DPPH (1,1diphenyl-2-picrylhydrazyl) radical scavenging assay. The results showed that the content of phenolic acids and antioxidant activity exhibited significant correlation coefficients.
