Resumen o descripción

The agave or maguey is endemic to America and Mexico is the place where you will find the

largest number of species of agave. In Zacatecas, Mexico, in the south and southeast regions

of the state grown Agave tequilana Weber (blue agave) and A. salmiana ssp. crassispina

(green agave) for the main production of beverages like “aguamiel, “pulque” and “mezcal”,

but due to the growth of this last activity, are being generated large amounts of waste solid

such as bagasse and leaves of agave, which are important to evaluate their possible use.

Zacatecas generated annually at least 21000 tons being about 30 percent agave leaves and

the rest agave bagasse. Currently they are not given an application to the leaves of agave and

has been found to exist in these residues some secondary metabolites of interest as saponins.

Agave saponins are amphipathic glycosides with triterpene or steroid skeletons whose

structural diversity is related to the wide range of biological effects are source sapogenins

basis for synthesis of therapeutic importance sterols. But the extraction, purification and

identification of these compounds are methodological challenges. The aim of this work is to

extract saponins and characterize the waste generated of the agribusiness mezcal.

Characterized by optical and scanning electron microscopic bagasse fiber and infrared

spectroscopy the content of organic matter, and calcium carbonate was evaluated. The

analysis of the composition of the leaves indicate a high content of crude fiber but low

content in fat and protein. Extracts from fresh leaves which were purified by column

chromatography and analyzed by thin layer chromatography were obtained to evaluate

saponins. All with the intention of seeking the possible uses of these compounds and the

reduction of waste generated in the production of mezcal.
