“…Some studies have used Agave tequilana to produce bioethanol [8,9], mainly due to its high content in carbohydrates. Saponines obtained from Agave americana were also studied as an additive in animal feeding, effectively increasing lamb growth [10], while others have studied the potential of salts found in Agave americana for fertilizers [11].…”

This paper summarises the results obtained from the characterization assays from century plant (Agave americana L.), determining the chemical composition of different parts of the plant. Fibres were obtained by means of a mechanical device, specifically designed and built for Agave americana leaves processing. Obtained fibres were subjected to thermogravimetric analysis and infrared spectra, and their chemical composition was also determined by quantitative acid hydrolysis. Once obtained, fibres were blended up to 40% (in weight) to obtain composites by compression moulding, using polyethylene as matrix; mechanical testing show improvements in elastic modulus for both tensile and flexural tests; increase in flexural maximum strength were also found for the composites, while tensile strength is slightly reduced with the introduction of agave fibres. The research is part of a project developed in the Macaronesian region, which aim is to demonstrate the feasibility of using biomass from invasive plant species in the composites sector as a way of financing control campaigns and habitats conservation labours, which is the main novelty of this research.

“…Moreover, other reports describe the presence of saponins in lechuguilla (Sidana et al, ; Soto, Lugo, Díaz, & Villanueva, ); nevertheless, there is no identification and classification of secondary metabolites present in the guishe extracts. In the present study, we report early identification of the molecules contained in guishe crude extract and the effect of the crude extract as a feed additive for shrimps.…”

“…Furthermore, recent studies show that guishe is composed of biomolecules such as phytochemicals, glucans and micronutrients as vitamins (Almaraz‐Abarca, Delgado‐Alvarado, Avila‐Reyes, Uribe‐Soto, & Gonzalez‐Valdez, ; Sidana, Singh, & Sharma, ). These biomolecules can be extracted and applied in different industrial sectors to give value to the by‐product, thus A. lechuguilla exploitation.…”

Evaluation ofAgave lechuguillaby‐product crude extract as a feed additive for juvenile shrimpLitopenaeus vannamei

et al. 2020

Agave lechuguilla is a succulent plant species, mainly distributed in the northeast of Mexico and south of the United States of America. The main use for this plant is the fibre´s extraction (known as Tampico fibres), resulting in 15% of fibres and 85% of a by‐product waste named guishe. The lechuguilla collectors, normally incinerate the guishe, thus causing environmental contamination. Interestingly, recent studies showed that guishe contains molecules with nutritional properties, such as saponins, flavonoids and sugars. Therefore, in this work, we evaluated the effect of the crude extract of guishe as a feed additive in whiteleg shrimp diets. According to that, MS‐HPLC analysis of the extract showed the presence of saponins such as diosgenin, smilagenin, hecogenin, manogenin, tigogenin hexose, yucagenin, chlorogenin, diosgenin diglucoside and the flavonol, quercetin. After chemical analysis, the crude extract was included into an experimental diet in four levels; 0% (L0%), 0.1% (L0.1%), 0.3% (L0.3%) and 0.6% (L0.6%). Dietary incorporation of the extract was evaluated by zootechnical performance, haemolymph biochemistry, histomorphology and digestive enzyme activity of shrimps. After 5‐week feeding, the L0.3% diet showed significantly higher growth and better feed utilization among treatments. A significant increase in tubule epithelium height and tubule coverage area from hepatopancreas in shrimp under L0.3% diet compared with the control diet suggest an improvement of the health and nutritional status of the shrimp. Inclusion of L0.3% and L0.6% of the crude extract resulted in a reduction in amylase activity, without effect in glucose levels in the haemolymph. Thus, we suggest that lechuguilla guishe crude extract contains nutritional molecules that may be used as a feed additive to promote shrimp productivity.

“…Natural and synthetic saponins inhibit the absorption of cholesterol in the intestine, reduce the concentration of plasma cholesterol in laboratory animals and are used for their pharmacological potential in the treatment of hypercholesterolaemia (Harwood Jr. et al, 1993). In recent studies, Liu et al (2015) reported that the dioscin, a natural steroid saponin that exists widely in various agave plants (Sidana et al, 2016), could cause gradual weight loss without inhibiting appetite or increasing the physical activity of obese mice. In addition, Leal-Díaz et al (2016) demonstrated that steroidal saponins extracted from Agave salmiana were able to reduce obesity-related metabolic abnormalities by promoting an abundance of Akkermansia muciniphila in the intestinal lumen.…”

Agave sisalana is a plant belonging to the Agavaceae family. Sisal juice is constituted of steroidic saponins which are precursor molecules of many pharmacologically active steroids. These precursor molecules can act in brain structures that are related to the modulation of emotional disorders. They can act on energy metabolism or directly on the absorptive process of fats. The objective of this research was to identify the biocompounds present in A. sisalana juice, and to evaluate the effect of different extracts on the expression of defensive behaviours of rats in elevated plus maze and open field tests, and body weight, in a condition that corresponds to an induced menopause. Wistar rats were subjected to bilateral ovariectomy or to a sham surgical procedure under anaesthesia. Following surgery, they were treated gavage with sisal juice -concentrated crude juice (CCJ): 500 or 1000 mg/kg; dried extract (DE): 50, 100 or 200 mg/kg; dry mucilage extract (DME): 25, 50 or 100 mg/kg; and intermediate product (IP): 25, 50 or 100 mg/kg; or distilled water. The results showed the presence of coumarins, flavonoids, condensed tannins, free anthraquinones, alkaloids and saponins in the sisal juice. Both CCJ and DE (100 mg/kg) caused weight loss without alteration of defensive behaviours related to the manifestation of anxiety. As saponins were identified in DE in significant amounts, the observed effects were attributed to this component. Such findings point to A. sisalana as a plant that could potentially be used to treat weight gain during menopause.
