The genus Tilia (Tiliaceae) represents 45 species, of which six species
are European. Tilia sp. are simple, cordate or deciduous trees with
long, silicate shaped, 5-valve fruits and fragrant flowers. It is used as a
medicinal tea in traditional medicine for colds, coughs, and hypertension
and as an antioxidant.
Within the scope of this research, Tilia platyphyllos Scop. in the culture
form from Eskişehir was obtained, and infusions were prepared at different
times (including 5 min., 10 min., 15 min., and 30 min., respectively).
Headspace-solid-phase microextraction (HS-SPME) combined with gas
chromatography-mass spectrometry (GC-MS) was used to examine the
volatile components in the infusion extracts. Major volatile compounds of
infusion extracts determined as E)-β-ocimene (15.7-45.9%) and limonene
(11.7-33.4%), respectively. Also, terpinolene (26.0%) were identified as
the main compounds for 30 min infusion. After then, the infusion extracts
were lyophilized, and the antioxidant activity of the infusion extracts were
performed by DPPH· radical scavenging effect. It was determined that
inhibition percentages were relatively high in the concentration range of
10-0.02 mg/mL (5.60-72.45%).
Our first research was the chemical composition and biological activity of
the time-dependent T. platyphyllos infusions.
