Abstract
The properties of the fatty substances of three mushrooms (F. fomentarius, T. orientalis and A. tabescens) and their components related to the fatty acids and unsaponifiable matters were investigated.
The mushrooms were dried, crushed and then extracted with ether. The oil contents of the dried matter were 2.7% (F. fomentarius), 0.6% (T. orientalis) and 5.7% (A. tabescens). The main fatty acids were C16 : 0 and C18 : 2 (F. fomentarius and T. orientalis) and C18 : 0 and C18 : 2 (A. tabescens).
The Δ5, 7-sterol-contents in their unsaponifiable matters were 4.2% (F. fomentarius), 11.5% (T. orientalis) and 21.0% (A. tabescens).
The main sterols seemed as Ergosterol in each, but 22, 23-dihydroergosterol was found in A. tabescens being 31% content. The non-sterol parts of the unsaponifiable matters were believed mainly consisting of long-chain alcohols in F. fomentarius and hydrocarbons in T. orientalis and A. tabescens. Moreover a carbonyl compound having mp 246°C was found in the unsaponifiable matter of T. orientalis.
