“…The crude extracts that showed the greatest change in coloration were: IR005 (Inonotus rickii), previous studies reported sesquiterpenes as inonotic acid A and B in the species I. rickii and in the close species I. obliquus; the presence of inotodiol, lanosterol, β-sitosterol, romadendrane sesquiterpenoids named inonotins (isolated from the culture) and nostane-type triterpenoids was also established for the genus Inonotus (Nomura et al, 2008;Kim et al, 2011;Chen et al, 2014;Isaka et al, 2017). Another positive species was PA008; Lobo et al (1983Lobo et al ( , 1988, Baumert et al (1997), Zamuner et al (2005) and Márquez-Fernandez (2013) described several types of sterols for Pisolithus tinctorius (Pisolithus arhizus) among them ergosterol, lanosterol and derivatives, agnosterol, piscolactone and the pisosteral. Regarding TC009, the positive results coincide with those of Leliebre-Lara et al (2015) who obtained positive results for the species T. versicolor; with respect to AG001 the extract indicated the presence of terpenoid compounds and sterols, previous studies.…”

Evaluación preliminar de compuestos fenólicos, actividad antioxidante y compuestos bioactivos de algunas especies de hongos basidiomicetes de Paraguay. Se realizó la identificación cualitativa de metabolitos secundarios y se cuantificó el contenido de compuestos fenólicos y el potencial antioxidante de extractos etanólicos de ocho géneros de macrohongos Amylosporus, Gloeophyllum, Hydnopolyporus, Inonotus, Laccaria, Lentinus, Pisolithus y Trametes por primera vez para el Paraguay. Los análisis químicos cualitativos revelaron la presencia de varios metabolitos secundarios tales como compuestos fenólicos, esteroles y terpenos. La especie Inonotus splitgerberi presentó valores de 64,81 ± 2,70 mg GAE.g -1 de compuestos fenólicos totales comparables con la especie medicinal Inonotus obliquus. También se proporcionan datos noveles para la especie Amylosporus guaraniticus.

“…However, the 1 H NMR spectrum of compound 4 shows an additional signal at 1.08 (3H, s) corresponding to methyl H-31 and the double signal assigned to H-21 (δ 0.95, 3H, s) appears slightly displaced. These compounds were assigned as 22-S-24-methyl-lanostan-8-en-22, 24'-epoxy-3-ol-24'ona (pisolactone) and 22-S-24, 25 dimethyl-lanostan-8-en-22, 24'-epoxy-3-ol-24'ona (25-methyl-pisolactone) according to their spectral data as compared to with the references consulted Lobo et al, 1983). Baumert et al (1997) reported the presence of triterpenes unfunctionalized at carbon-23, equal to those found in this paper, from mycelium on surface culture, suspension culture and mycorrhiza, differing only in their concentration, resulting in a greater proportion of the triterpenes 2 and 4, when they preceded from mycorrhizal association than in culture in vitro .…”

RESUMENL os hongos micorrizógenos se encuentran en asociación con las raíces de muchas plantas, incluyendo casi todas las especies de árboles como la familia Pinaceae. Algunos derivados triterpé-nicos de lanosterol se han aislado tanto del micelio como de los cuerpos fructíferos del hongo ectomicorrizógeno Pisolithus arhizus. En el presente trabajo, se cultivó una cepa de la especie P. arhizus, aislada de bosques de pino en Oaxaca en condiciones de laboratorio, con el fin de determinar qué tipo de compuestos se pueden encontrar en una cepa mexicana cultivada bajo condiciones asimbió-ticas y sus posibles implicaciones ecológicas. Los resultados confirman que, en la fermentación líquida in vitro del micelio, la cepa aislada de los bosques de México presenta el mismo tipo de triterpenos sin funcionalidad con el carbono-23 como otras cepas procedentes de bosques de Europa y Brasil, a pesar de que se utilizó un medio de cultivo PDA en lugar del medio de cultivo Melin-Norkrans. ABSTRACTM ycorrhizal fungi can be found in association with the roots of many plants, including almost all tree species such as the Pinaceae family. Some triterpene derivatives of lanosterol have been isolated both in the mycelium as well as in the fruiting bodies of the ectomycorrhizal fungus Pisolithus arhizus. In order to determine, what type of compounds can be found as well as any possible ecological implications involved in the case of a Mexican strain cultivated under asymbiotic conditions in the present research work, a strain isolated from P. arhizus from pine woods from Oaxaca was grown under laboratory conditions. These results confirm that the strain isolated from the forests of Mexico presents the same type of triterpenes unfunctionalized at carbon-23 in the in vitro liquid fermentation of mycelium, like other strains from forests in Europe and Brazil, despite the fact that they we used a PDA medium culture instead of a half Melin-Norkrans medium culture.
