Journal ArticleDOI
Saponins of Agave: Chemistry and bioactivity.
TL;DR: The present review describes 141 steroidal saponins and sapogenins of Agave and covers the literature published from 1970 to 2015, a comprehensive and coherent presentation of the structures, methods of chemical profiling, structure elucidation and biological activities.
Journal ArticleDOI
Effect of in vitro drought stress on phenolic acids, flavonols, saponins, and antioxidant activity in Agave salmiana
TL;DR: Plants cultured in vitro increased their saponin content and antioxidant activity in response to drought stress induced via PEG, and total phenolic compounds did not significantly differ between treatments.
Journal ArticleDOI
Agave as a model CAM crop system for a warming and drying world
TL;DR: Despite the many unknowns regarding agaves, they provide a means to resolve disparities in resource availability and needs between natural and human systems in semi-arid regions and show considerable promise as an alternative source for food, alternative sweeteners, and even bioenergy.

Biological activities of Agave by-products and their possible applications in food and pharmaceuticals
Julio Cesar Lopez-Romero,Jesús Fernando Ayala-Zavala,Gustavo A. González-Aguilar,Etna Aida Peña-Ramos,Humberto González-Ríos +4 more
TL;DR: Agave leaves are considered a by-product of alcoholic beverage production (tequila, mezcal and bacanora) because they are discarded during the production process, despite accounting for approximately 50% of the total plant weight, and these by-products constitute a potential source of Agave extracts rich in bioactive compounds.

Journal ArticleDOI
Use of a Free Radical Method to Evaluate Antioxidant Activity
TL;DR: The antiradical properties of various antioxidants were determined using the free radical 2,2-Diphenyl-1-picrylhydrazyl (DPPH*) in its radical form as discussed by the authors.
Journal Article
Colorimetry of Total Phenolics with Phosphomolybdic-Phosphotungstic Acid Reagents
TL;DR: In this paper, the use of Folin-Ciocalteu reagent rather than the FolinDenis reagent, gallic acid as a reference standard, and a more reproducible time-temperature color development period was investigated.
Journal ArticleDOI
Antioxidant activity applying an improved ABTS radical cation decolorization assay.
Roberta Re,Nicoletta Pellegrini,Anna R. Proteggente,Ananth S. Pannala,Min Yang,Catherine Rice-Evans +5 more
TL;DR: A method for the screening of antioxidant activity is reported as a decolorization assay applicable to both lipophilic and hydrophilic antioxidants, including flavonoids, hydroxycinnamates, carotenoids, and plasma antioxidants.
Journal ArticleDOI
Standardized Methods for the Determination of Antioxidant Capacity and Phenolics in Foods and Dietary Supplements
TL;DR: Methods available for the measurement of antioxidant capacity are reviewed, presenting the general chemistry underlying the assays, the types of molecules detected, and the most important advantages and shortcomings of each method.
