          Abstract

          Abstract This research presents the results of the proximal analysis of turmeric rhizome flour (Curcuma longa) from different areas of Valle del Cauca (Colombia) and the quantitative estimation of the uptake of the radical 2,2-diphenyl-1-Picrylhydrazyl (DDPH) of the methanolic extracts of the flour. The results of the proximal analysqAis evidence that some parameters do not show evident differences. However, others, such as total fat, show differences between the turmeric crops with conventional and agroecological fertilization. The values obtained from the different samples for proteins and carbohydrates are in an average normal range (9.3% and 70.5%, respectively), which fulfills the requirement to be a nutritional supplement. The free radical uptake (FRS) test of the extracts showed an antioxidant activity of the different samples tested for FRS50 (%) of 2.11 ± 0.06 µg/mL (Yumbillo, Y), 1.34 ± 0.26 µg/mL (Guacas, G), 4.22 ± 0.06 µg/mL (Magdalena, M), 9.16 ± 0.32 µg/mL (Commercial, C), 1.29 ± 0.26 µg/mL (Santa Rosa de Tapias, SR), and 1.33 ± 0.05 µg/mL (Limonar, L), which were contrasted with the values of quercetin (Q) 1.01 ± 0.51 µg/mL, vitamin C (V) 2.07 ± 0.45 µg/mL, and piperine (P ) 0,0 µg/mL. The proximal nutritional value plus the oxidizing activity, due to the concentration of phenolic compounds, make turmeric flour a functional food.

          Resumo Esta pesquisa apresenta os resultados da análise proximal da farinha de rizoma de cúrcuma (Curcuma longa) de diferentes áreas do Vale do Cauca (Colômbia), além da estimativa quantitativa da captação do radical 2,2-difenil-1-Picrylhydrazyl (DDPH) dos extratos metanólicos da farinha. Os resultados da análise proximal mostram que alguns parâmetros não mostram diferenças óbvias. No entanto, outros, como gordura total, mostram diferenças entre a cúrcuma das culturas com adubação convencional e agroecológica. Os valores obtidos nas diferentes amostras para proteínas e carboidratos estão em uma faixa média normal (9,3% e 70,5% respectivamente), que estão dentro dos valores necessários para ser um suplemento nutricional. O teste de captação de radicais livres (FRS) dos extratos mostrou uma atividade antioxidante das diferentes amostras testadas para FRS50 (%) de 2,11 ± 0,06 μg/mL (Yumbillo, Y), 1,34 ± 0,26 μg/mL (Guacas, G), 4,22 ± 0,06 μg/mL (Magdalena, M), 9,16 ± 0,32 μg/mL (Comercial, C), 1,29 ± 0,26 μg/mL (Santa Rosa de Tapias, SR) e 1,33 ± 0,05 μg/mL (Limonar, L), que foram contrastados com os valores de quercetina (Q) 1,01 ± 0,51 μg/mL, vitamina C (V) 2,07 ± 0,45 μg/mL e piperina (P ) 0,0 μg/mL. O valor nutricional proximal mais a atividade oxidante, devido à concentração de compostos fenólicos, fazem da farinha de cúrcuma um alimento funcional.

          Biological activities of curcuminoids, other biomolecules from turmeric and their derivatives – A review

          In recent years, several drugs have been developed deriving from traditional products and current drug research is actively investigating the possible therapeutic roles of many Ayruvedic and Traditional Indian medicinal therapies. Among those being investigated is Turmeric. Its most important active ingredient is curcuminoids. Curcuminoids are phenolic compounds commonly used as a spice, pigment and additive also utilized as a therapeutic agent used in several foods. Comprehensive research over the last century has revealed several important functions of curcuminoids. Various preclinical cell culture and animals studies suggest that curcuminoids have extensive biological activity as an antioxidant, neuroprotective, antitumor, anti-inflammatory, anti-acidogenic, radioprotective and arthritis. Different clinical trials also suggest a potential therapeutic role for curcuminoids in numerous chronic diseases such as colon cancer, lung cancer, breast cancer, inflammatory bowel diseases. The aim of this review is to summarize the chemistry, analog, metal complex, formulations of curcuminoids and their biological activities.

            Degradation of Curcumin: From Mechanism to Biological Implications.

            Curcumin is the main bioactive ingredient in turmeric extract and widely consumed as part of the spice mix curry or as a dietary supplement. Turmeric has a long history of therapeutic application in traditional Asian medicine. Biomedical studies conducted in the past two decades have identified a large number of cellular targets and effects of curcumin. In vitro curcumin rapidly degrades in an autoxidative transformation to diverse chemical species, the formation of which has only recently been appreciated. This paper discusses how the degradation and metabolism of curcumin, through products and their mechanism of formation, provide a basis for the interpretation of preclinical data and clinical studies. It is suggested that the previously unrecognized diversity of its degradation products could be an important factor in explaining the polypharmacology of curcumin.

              Biological activities of Curcuma longa L.

              There are several data in the literature indicating a great variety of pharmacological activities of Curcuma longa L. (Zingiberaceae), which exhibit anti-inflammatory, anti-human immunodeficiency virus, anti-bacteria, antioxidant effects and nematocidal activities. Curcumin is a major component in Curcuma longa L., being responsible for its biological actions. Other extracts of this plant has been showing potency too. In vitro, curcumin exhibits anti-parasitic, antispasmodic, anti-inflammatory and gastrointestinal effects; and also inhibits carcinogenesis and cancer growth. In vivo, there are experiments showing the anti-parasitic, anti-inflammatory potency of curcumin and extracts of C. longa L. by parenteral and oral application in animal models. In this present work we make an overview of the pharmacological activities of C. longa L., showing its importance.
