Purification and Identification of Chemical Constituents of Basidiomycete Daedaleopsis tricolor Collected from Mazandaran Province, Iran

Abstract

Background and purpose: Mushrooms are natural sources that have antitumoral effects, immunomodulatory and anti-oxidant effects. One of the fungus which remained intact is Daedaleopsis tricolor that belongs to the family of Polyporaceae. There are limited phytochemical investigations on other species of this genus, so, we aimed at performing a phytochemical analysis of this fungus. Materials and methods: Fungal components were extracted by hexane using maceration method. Then, the extract was concentrated under reduced pressure using a rotary evaporator. The concentration extract was subjected to silica gel column chromatography through mobile phases consisting of hexane: ethyl acetate. Three fractions of hexane purified extract were called F3, F2, and F1. They were analyzed by 1H-NMR and 13C-NMR Spectroscopy and DEPT 90 and DEPT 135 experiments. Results: After analysis and receiving the spectrum results and comparing them with other studies, we identified ergosterol derived compounds, ergosterol peroxide, ergosta-7, 22-dien-3β-ol, and linoleic acid. Conclusion: The three compounds, including ergosterol peroxide, ergosta-7, 22-dien-3β-ol, and linoleic acid were reported for the first time in this fungus.
