Resumen:
Three compounds were were characterized for the first time from the genus Gutierrezia.Flavones and flavonols methoxylated are important groups of compounds in the genus Gutierrezia. These compounds are characterized by a combination of extra oxygenated A-rings, and several B-ring oxygenation patterns. The presence of flavonoids confirms that, like other members of genus Gutierrezia, G. mandonii is able to produceflavonoids with 5,7-dihydroxy-6-methoxy substitution in A-rings, and 40-oxygenation in B-rings.In Gutierrezia, only one aromadendrane sesquiterpenoid, spathulenol 1, has been described.
