Content Of The Polar Fraction Of An European Mushroom: Suillus bellinii (Inzenga) Watling

Suillus bellinii (Inzenga) Watling is a mushroom belonging to the Botelaceae family. The fruiting bodies are characterized by an irregular cap, large pores, a short and squat stem and lastly a whitish dampish flesh with a very sweet taste. Right for these features it is considered one of the most appreciated species of Suillus group. This species, as well as several edible fungi, is often employed as component of low caloric diets. Moreover it’s widely utilized for its high tumor inhibiting and cytotoxic properties. In this work we report the composition of the methanolic fraction obtained from the fruiting bodies of this mushroom. Four major classes of compounds were isolated: fatty acids, terpenoids, amino acids and one aromatic ketone. The fatty acids are still under study to determine the specific compounds as well as the isolated terpenoid and the aromatic ketone. On the other hand it was identified suillin which is formed by a diterpenic chain linked to an aromatic ring in the position 3. This compound was found for the first time in this species although not in the genus and, togheter with isosuillin, it’s responsible for the pharmacological activity of this mushroom. For what concerns the amino acidic part, some were identified like tryptophan and threonine while further analysis is necessary to confirm the suspected presence of valine, leucine and phenylalanine. The presence of amino acids add some nutritional value to this edible fungus.
