N2 - Description or the subject. Agave potatorum Zucc. leaves make up the highest proportion of non-valued residue of the agave-mezcal process. Interest in their study lies in the presence of secondary metabolites with potential biological activity. Objectives. To evaluate the effect of a crude (CE) and fractionated extract of Agave leaves on mycelial growth of different strains of the genus Pleurotus. Method: The CE, obtained by maceration of A. potatorum leaves, was fractionated giving rise to ethyl acetate (AcOEt) and aqueous (Aq) fractions, in which a phytochemical screening was assessed. The effect in vitro of the CE and the AcOEt fraction on mycelial growth rate of Pleurotus sp. (12 days at 25 °C) was evaluated, whereas the CE and the Aq fraction were assessed for P. pulmonarius and P. djamor.Results: The CE and the AcOEt fraction at 1 000 ppm increased the mycelium growth rate of Pleurotus sp. by 61 and 36 %, respectively, relative to the control. CE induced greater growth, significantly different from the control at 1 000 ppm, only on P. djamor, while the Aq fraction at 1 000 ppm was not significantly different from the control; and at 5 000 ppm growth in both strains was inhibited. Regardless of the concentration or the fraction assessed, mycelia showed higher density and more aerial growth than the control. Conclusions: The A. potatorum leaf extract contains secondary metabolites capable of accelerating radial growth of Pleurotus strains, which may lead to revaluing the leaves of this Agave.
