15. A comparison of plating and reverse transcriptase polymerase chain reaction followed by microchip electrophoresis for the inactivation of Alicyclobacillus acidoterrestris using saponin
Foi utilizada a reação em cadeia da polimerase via transcriptase reversa (RT-PCR) seguida por eletroforese capilar em microchip para avaliar a viabilidade de esporos de Alicyclobacillus acidoterrestris após a inativação com saponina e temperatura. O método demonstrou ser adequado para tal propósito, além de ser mais rápido e sensível que a tradicio

16. Application of foam column as green technology for concentration of saponins from sisal (Agave sisalana) and Juá (Ziziphus joazeiro)
Saponins, molecules classified as triterpenic or steroidal glycosides, are metabolites distributed in all the plant kingdom that can be used for the production of foods, cosmetics, and pharmaceuticals, as well as in soil bioremediation. Saponins are normally extracted from natural resources with water, ethanol and/or methanol, and then concentrated by liquid

17. Saponins, tannins and flavonols found in hydroethanolic extract from Periandra dulcis roots
Periandra dulcis Mart. ex Benth. Fabaceae (Syn.: P. mediterranea (Vell.) Taub.) is native to the northern and middle parts of Brazil. In Brazilian ethnomedicine, their roots are used as anti inflammatory, expectorant, diuretic and laxative. An HPLC-ESI-MS/MS system was employed to provide a rapid method to make a tentative characterization of the compounds f

18. Caracterização nutricional e antinutricional de folhas de Abelmoschus esculentus (L.) Moench; atividade microbiológica da lectina presente na fração 30%
The non-conventional vegetabless leafy such as seeds, stems, leaves and crumbs, can be inserted in food as an alternative source of nutrients. Among the alternatives, there is okras leaves (Abelmoschus esculentus), vegetable belonging to the Malvaceae family, is widespread in tropical regions. However, the bioavailability of nutrients can be affected by anti

19. Anti-schistosomiasis triterpene glycoside from the Egyptian medicinal plant Asparagus stipularis
Bioassay-guided isolation using an in vitro assay testing for anti- schistosomiasis yielded a novel triterpene saponin, asparagalin A, from the n-butanol extract of the roots of Asparagus stipularis Forssk., Asparagaceae. The structure was elucidated by spectroscopic analysis and chemical transformations. Administration of asparagalin A resulted in a retarda

20. Avaliação in vivo da eficiência de dois imunógenos recombinantes derivados do peptídeo SBm7462 para o controle do carrapato Rhipicephalus (Boophilus) microplus (Canestrini 1887) / Evaluation efficacy in live of two recombinant immunogens derivatives of peptide SBm7462 in the control of the tick Rhipicephalus (Boophilus) microplus (Canestrini 1887)
Recombinant peptides rBmseq1 and RBmseq4 were evaluated as immunogenic for the control of ticks R. (B. ) microplus in test of stable. We used 17 bovine animals of the half-breed average degree of blood of 7/8 (H/Z), which were kept under the management routine in the Sector of isolation of bovine animals in the Department of Veterinary UFV. The animals were

23. Obtenção e caracterização de frações purificadas de saponinas de chenopodium quinoa e avaliação da formação de complexos do tipo iscom : atividades biológicas das frações e dos complexos formados
Chenopodium quinoa (quinoa) seeds are a rich protein source and well-known for their high saponin content. Chemically, quinoa saponins are triterpene glycosides being phytolaccagenic, hederagenin, oleanolic and serjanic acids the most common aglycones found in seeds. Its immunoadjuvant properties have been examined and the results obtained were conflicting.

24. Triterpenes and new saponins from Ilex chamaedryfolia: chemotaxonomic tool to ilex species differentiation
Three saponins were isolated from leaves of Ilex chamaedryfolia. Their structures were established by spectroscopic and mass spectrometry data as the new saponin 3β-O-β-D-glucopyranosyl-(1-3)-α-L-arabinopyranosyl-20( S)-19α-hydroxyurs-12-en-28-oic acid 28-O-β-D-glucopyranosyl-(1-3)-β-D-glucopyranosyl ester, the new saponin 3β-O-β-D-glucopyranosyl-(1-
