Resumen
Cinco compuestos de una cepa comercial del hongo Pleurotus sp. se obtuvieron a partir de extracciones con acetato de etilo y metanol. Los compuestos se aislaron por medio de técnicas como la cromatografía en columna y en capa fina. Los siguientes esteroles fueron identificados mediante espectroscopía RMN 1H: 1) ergosta-5, 7, 22-trien-3β-ol (ergosterol), 2) 5α, 8α-epidioxi-22E-ergosta-6, 22-dien-3β-ol (peróxido de ergosterol), 3) 3β, 5α, 6β, 9α-tetrahidroxiergosta-7, 22-dieno, 4) 3β, 5α, 6β, 9α-tetrahydroxyergosta-7, 22-dien y 5) 3β, 5α, 9α-trihidroxiergosta-7, 22-dien-6-ona.
