El extracto metanólico de <i>Tillandsia recurvata</i> reduce los niveles de glucosa, triglicéridos y colesterol en sangre

Background: Tillandsia recurvata collected in San Luis Potosí does not have studies focused on its use as an adjuvant in treating diabetes mellitus. Questions and / or Hypotheses: Will Tillandsia recurvata L. (Bromeliaceae) have antidiabetic activity in vitro and in vivo? Studied species: Tillandsia recurvata L. (Bromeliaceae) Study site and dates: T. recurvata was collected in Guadalcázar municipality, San Luis Potosí, México, in December 2021. Methods: The antidiabetic potential of Tillandsia recurvata methanol extract (TRM) was evaluated using in vitro and in vivo models, and its secondary metabolite content was analyzed using Gas chromatography-mass spectrometry. Results: Results demonstrate that extract reduces blood glucose, triglyceride, and cholesterol levels in vivo. In addition, in vitro tests showed that extract diminished the formation of advanced glycation end products, methylglyoxal concentrations, and glycosylated hemoglobin levels. Gas chromatography-mass spectrometry analysis identified several compounds in the extract, including 2-methylbenzaldehyde, 4-hydroxy-2-methylacetophenone, 3',5' dimethoxyacetophenone, pentanoic acid, palmitic acid, linoleic acid, phytol, margaric acid, oleamide, cis-11-eicosenamide, stearic acid, 13-docosenamide, (Z), campesterol, and β-sitosterol. Conclusions: These results highlight the potential of T. recurvata collected in San Luis Potosi as an adjuvant in treatment of diabetes mellitus.
