Abstract
The search for natural products that has therapeutic properties with little or no
side effects has been the main subject around the world. Different plants have
been and are being explored for their medicinal properties. However, higher
fungi remain a vast and a large source of new pharmaceutical products yet to be
explored. The phyto-constituents in the ethanolic extract of Six edible wood
rotten fungi were investigated by Gas Chromatography-Mass Spectrometry
(GC-MS) analysis. The results showed that a total of 25 phyto-constituents were
revealed in Ganoderma lucidum and Pleurotus florida while 17 compounds
were revealed in Pleurotus eryngii and Pleurotus pulmonarius. Pleurotus
ostreatus and Pleurotus sajor-caju recorded 31 and 30 phyto-constituents
respectively. Some constituents were common to all the fungi while some were
absent in some fungi. Generally, most of them occurred in trace amount while a
few of the constituents occurred in large amount. Some bioactive compounds
such as Methyl stearate, Hexadecanoic acid, methyl ester, (Z)-, Hexadecanoic
acid, ethyl ester, 11,14-Octadecadienoic acid, methyl ester and 9-Octadecenoic
acid methyl ester were common to all the fungi extract. Four of the fungi had
cholesterol content which was however in trace amount of 1.37%, 1.22%, 1.16%
and 0.68% for G. lucidum, P. eryngii, P. ostreatus and P. pulmonarius
respectively. Of the compounds, 9-Octadecenoic acid, methyl ester, (E)- had the
highest concentration of 35.08% in P. pulmonarius. This was closely followed
by 11,14-Octadecadienoic acid methyl ester also in P. pulmonarius. Although,
the concentration varied across the fungi extracts. The bio-active components in
these fungi species could serve as a lead for development of novel natural
products with therapeautic properties.
