“…The presence of various functional components like polysaccharides, flavonoids, and carotenoids in L. barbarum L. fruits is believed to be responsible for these effects (He et al 2012;Yao et al 2011). Several physiological studies have focused on polysaccharides and carotenoids; however, flavonoids have been less investigated, especially for their antioxidant activity (Amagase and Farnsworth 2011;Potterat 2010).…”

Polyphenols are the important active compounds present in the fruits of Lycium barbarum L. The objectives of this study were to develop an ultra-high performance liquid chromatography with UV detection (UHPLC-UV) method for qualitative and quantitative analyses of phenolic acids and flavonoids in fruits of L. barbarum L. The isolation and enrichment of polyphenols from fruits were carried out by ultrasound-assisted extraction (UAE) in conjunction with solid-phase extraction (SPE). The analytes were separated on a Poroshell 120 EC-C18 column using a binary mobile phase composed of aqueous 0.05 % trifluoroacetic acid and acetonitrile in the gradient elution mode. Under these conditions, phenolic acids and flavonoids were separated in 11 min. The selectivity of the developed UHPLC-UV method was confirmed by comparison with ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analysis. The validation parameters such as linearity, sensitivity, precision, and accuracy were found to be highly satisfactory. The optimized method was successfully applied to the analysis of polyphenols in fruits of L. barbarum L. Additionally, their free radicalscavenging activity was assessed by 1,1-diphenyl-2-picrylhydrazyl radical (DPPH • ).

“…Na "goji berry" o flavonoide encontrado é conhecido por rutina. (FOOD INGREDIENTES BRASIL, 2009;(AMAGASE & FARNSWORTH, 2011) Os pesquisadores AMAGASE & NANCE (2011) realizaram um estudo com homens e mulheres acima do peso, porém saudáveis, avaliando o aumento do gasto calórico e diminuição da circunferência abdominal a partir do consumo de um suco à base de "goji berry". Dois grupos foram usados para a pesquisa: um grupo placebo (15 pacientes), e um grupo que fez suplementação com a bebida à base de "goji berry" (14 pacientes).…”

“…Seu nome botânico surgiu em 1753 pelo botânico sueco Carolus Linnaeu. (AMAGASE & FARNSWORTH, 2011) Pertencente à família Solanaceae de plantas angiospermas e de ordem Solanales, a Lycium barbarum L. pode chegar até 3 metros de altura. Suas folhas são verdes e cinzas (alternadamente) e lanceoladas.…”

“…Seu pericarpo é de coloração vermelha a vermelho escuro. (AMAGASE & FARNSWORTH, 2011) Não se conhece ao certo seu país de origem, porém, sabe-se que a fruta cresce naturalmente na Ásia principalmente no noroeste da China (Tibet e Mongolia). (AMAGASE & FARNSWORTH, 2011) …”

“…Pelo fato do AA ser instável, sua absorção se torna rápida, porém sua capacidade de armazenamento fica prejudicada e, consequentemente, seu uso terapêutico. No entanto, o AA-2βG é mais estável que o AA, surgindo assim uma nova possibilidade para o uso medicinal da Lycium barbarum L. (ZHANG et al, 2011;AMAGASE & FARNSWORTH, 2011) Outra propriedade de interesse é a presença do carotenoide zeaxantina, que se encontra em evidência em relação a outras fontes vegetais. (BORGUINI et al, 2012) A "goji berry", de acordo com o estabelecido na Resolução n° 16/1999, é enquadrada como um novo produto, visto que é um alimento que não é conhecido no Brasil, mas com um histórico de consumo em outro país.…”

RESUMO:A ''goji berry'' (Lycium barbarum L.) tem seus primeiros relatos na China onde era utilizada como planta medicinal. A "goji berry" é um fruto com um grande potencial antioxidante devido à presença de flavonoides, além de ser fonte de um análogo do ácido ascórbico denominado ácido ascórbico 2-O-β-D-Glucopiranosílico ou AA2βG, bem como ser fonte natural do carotenoide zeaxatina. Apresenta também polissacarídeos específicos que se mostram eficientes no aumento da atividade de enzimas antioxidantes. Nos dias atuais chegou ao mercado com a promessa de emagrecimento. Estudos realizados com uma bebida à base do suco desta fruta apontaram para uma possível diminuição da circunferência abdominal em indivíduos que fizessem o uso diário desta bebida. No entanto, as propriedades do ácido ascórbico 2-O-β-D-Glucopiranosílico (eficaz no tratamento da Desordem Osteogênica de Shionogi (DOS)), e a zeaxantina (importante aliado na prevenção da Degeneração Macular Relacionada a Idade (DMRI)), não são devidamente valorizados pela área de saúde até o momento. Cuidados devem ser tomados com a ingestão da fruta, pois pode levar a alergia pacientes que já tenham sido sensibilizados com o tomate, além de apresentar alguma interação com medicamentos antiplaquetários, diminuindo sua eficácia. A procedência de produto também deve ser conhecida visto que se encontrou níveis alterados de metais e pesticidas em amostras desidratadas de "goji berry" analisadas na Espanha. Palavras-chave: Lycium barbarum L.; goji berry; ácido ascórbico 2-O-β-DGlucopiranosílico; zeaxantina; efeitos adversos goji berry. ABSTRACT:The goji berry (Lycium barbarum L.) has its first reports in China where it was used as a medicinal plant. The goji berry is a fruit with a great antioxidant potential due to the presence of flavonoids, besides being a source of an analogue of ascorbic acid named 2-O-β-D-Glucopyranosyl Ascorbic Acid or AA2βG and as a natural source of carotenoid zeaxhantin. It also has specific polysaccharides that can increase the antioxidant enzymes activity. Nowadays it is offered in the market promising weight loss. Studies using its juice as a drink showed a possible decrease in waist circumference in individuals who uses daily this drink. However, the 2-O-β-D-Glucopyranosyl ascorbic acid properties (effective in the treatment of Osteogenic Disorder Shionogi (ODS)), and zeaxanthin (important in preventing Age-Related Macular degeneration (AMD or ARMD)), are not properly valued by health area yet. The goji berry intake may cause allergy to the patients who have already been sensitized with tomato, as well as presenting some interaction with antiplatelet drugs, reducing its efficacy. Dehydrated samples of goji berry were analyzed in Spain and have been found altered levels of metals and pesticides, demonstrating the importance of product origin identification. Key words: Lycium barbarum L., goji berry, foods for weight loss, 2-O-β-DGlucopyranosyl ascorbic acid, zeaxhantin, goji berry allergy. INTRODUÇÃOConhecida desde longa data na China, a "goji...
