n the framework of our phytochemical studies on edible
mushrooms, we report herein, the chemical analyses
of selected species of truffles (
Tuber aestivum, T.
melanosporum, T. mesentericum, T. magnatum, T. borchii,
T. brumale
and
T. uncinatum
and
Ganoderma lucidum
)
growing wild in North Greece (all truffles) and Lesvos island
respectively. Truffles are the fruiting bodies of mychorrhizal
filamentous fungi well-known and valuable as food, since
antiquity regarding to their unique taste and peculiar
aroma.
G. lucidum
is the most appreciated and widely used
medicinal mushroom in Asia, since last 2400 years. The aim
of this study was to qualify and quantify their aroma profile
by Headspace Solid-Phase Micro extraction (HS-SPME) οn
fresh, frozen and dried samples, comparing them with five
commercial truffle olive oils of the Greek market. Isolation
procedures through different extractions and analytical
techniques were further evaluated and the isolated
metaboliteswerestructurallydeterminedbymodernspectral
means. All studied samples were compared regarding their
total phenolic content by Folin Ciocalteu. Their antioxidant
and
in vitro
enzyme inhibitory properties were determined
using free radical scavenging (DPPH, ABTS), reducing
power (FRAP, CUPRAC), phosphomolybdenum and ferrous
ion chelating assays, while they were also evaluated against
cholinesterases, α-amylase and α-glucosidase enzymes.
Finally, their antimicrobial activity was evaluated against a
panel of human pathogenic bacteria and fungi showing an
interesting profile.
