1. Screening and Binding Analysis of Flavonoids with Alpha-Amylase Inhibitory Activity from Lotus Leaf
Lotus leaf is gaining growing popularity due to its various benefits and widely usage. In this paper, ten flavonoids in lotus leaf extract were analyzed by high performance liquid chromatography (HPLC). Centrifugal ultrafiltration combined liquid chromatography was used to screen alpha-amylase inhibitors from ten flavonoids mixture and the binding degrees ra

2. Antioxidant α-amylase inhibitors flavonoids from Iris germanica rhizomes
ABSTRACT A new isoflavonoid glycoside, iridin A (9), along with eight known isoflavonoids: irilone 4'-methyl ether (1), irilone (2), irisolidone (3), irigenin S (4), irigenin (5), irilone 4'-O-β-D-glucopyranoside (6), iridin S (7), and iridin (8) were separated from Iris × germanica L., Iridaceae, rhizomes. The structural elucidation of these flavonoids wa

3. Metanolic extract of Malpighia emarginata bagasse: phenolic compounds and inhibitory potential on digestive enzymes
ABSTRACT Adding value to fruit residues is of great interest, since they can be presented as a viable solution in search of new drugs for the treatment of obesity and related diseases, due to bioactive substances, especially phenolic compounds. Thus, the objective of this study was to prepare the methanol extract of acerola bagasse flour, in order to evaluat

4. Effect of soaking on the nutritional quality of pequi (Caryocar brasiliense Camb.) peel flour
Pequi peel comprises 76% of the whole fruit and it is discarded during consumption. Thus, pequi peel has been considered a solid residue, although it has potential for use in various applications. Limitations in the use of this material are mainly due to the lack of information of its nutritional composition, especially about the toxic or antinutritional fac

5. Inhibition of pancreatic lipase by extracts of Baccharis trimera (Less.) DC., Asteraceae: evaluation of antinutrients and effect on glycosidases
In order to confirm the traditional use of Baccharis trimera (Less.) DC., Asteraceae, for the reduction of weight, plant extracts were evaluated on the activity of pancreatic lipase (PL), an enzyme responsible for hydrolysis of triacylglycerols in the diet for its subsequent absorption. The aqueous and infused extracts did not show inhibitory activity on the

6. Mutants of common bean alpha-amylase inhibitor-2 as an approach to investigate binding specificity to alpha-amylases.
Despite the presence of a family of defense proteins, Phaseolus vulgaris can be attacked by bruchid insects resulting in serious damage to stored grains. The two distinct active forms of a-amylase inhibitors, a-AI1 and a-AI2, in P. vulgaris show different specificity toward a-amylases. Zabrotes subfasciatus a-amylase is inhibited by a-AI2 but not by a-AI1. I

8. As Enzimas presentes no trato digestivo dos insetos : um alvo susceptível de inibição
Seeds of scarlet runner bean (Phaseolus coccineus L.) were analyzed for -amylase inhibitor (-AI) activity. By using polyclonal antibodies raised against pure a−AI-1 from common bean (Phaseolus vulgaris L.) it was possible to detect the typical -AI polypeptides (Mr 14 -18 kDa) as well as a large polypeptide of Mr 32,000 Da. Differential inhibition curve

9. Caracterização bioquímica de amêndoas cruas e torradas de chichá ( Sterculia striata A. St. Hill &Naudin) / Biochemical characterization of raw and roasted almonds of chichá ( Sterculia striata A. St. Hill &Naudin)
Many species from Cerrado remain unknown in their biochemical characteristics and in their potential for food processing. This work had as objective to characterize the almond of chichá from the specie Sterculia striata A. St. Hill &Naudin, originated from Corrente (Piauí) in their biochemical components, analyze the changes in the chemical composition and

10. Enzimas de organismos aquÃticos e suas aplicaÃÃes fisiolÃgicas
In the last years, there has been a general increase in human demand for fishery products, followed by a significant increase in the world production of aquatic organisms. The growth of fishery industry generates, as consequence, large amounts of wastes and by-products rich in biomolecules, which are discharged into envioronment. Fishery wastes can be used i

11. Filogeografia molecular e atividade de enzimas digestivas do caruncho-do-feijão Acanthoscelides obtectus (Bruchidae:Coleoptera) / Phylogeography and molecular activity of digestive enzymes of bean-weevil, Acanthoscelides obtectus (Bruchidae:Coleoptera)
In the world, Brazil stands out as a major producer and consumer in the world of common bean, Phaseolus vulgaris, however has low productivity due to several factors among them, low technological level used in the cultivation and lack of care mainly plant grain during the storage of . Large losses in the storage of bean (P. vulgaris) are attributed to grain

12. Ação inibitória de extratos de plantas do Cerrado sobre α-amilases com ênfase em Kielmeyera coriacea
α-amylases are digestive enzymes widely distributed in microrganims, plants and animals, that catalyze hidrolysis of α-1,4 glicosidic bonds and act in carbohydrate metabolism. The inhibition of α-amylases can be applied on control of insect pests that depends on starch-rich diet to energy production, reducing the amount of nutrients to avoid i
