| Summary: | Plane
tree belongs to Platanaceae family. There is a widespread belief that Platanus orientalis leaves (POLs) have beneficial
effects on joint disorders. Therefore, many people consume POLs as tea. To our knowledge,
as there is no study on volatile compounds (VCs) of POLs, we objected to determine
the VCs in POLs obtained from Platanus orientalis
trees grown in Hatay province, Turkey. The VCs were extracted using solid phase
micro-extraction (SPME) and analyzed by gas chromatography-mass spectrometry (GC-MS).
A total of 140 VCs were found in POLs. Aldehydes, alcohols, ketones, terpenes and
alkenes were determined in POLs as major VCs groups, which accounted for 32.40 %,
23.51 %, 18.08 %, 10.24 % and 4.82 % of total VCs identified, respectively. Trans, trans-2,4-heptadienal (6.62 %), nonanal (6.46 %), benzaldehyde (6.42
%), cis-3-hexen-1-ol (6.32 %), benzenemethanol
(6.13 %) were the most abundant VCs identified in POLs. Trans-2-hexenal (3.46 %), 3-phenyl-2-butanone (2.87 %), trans-3,5-dimethyl-1,6-octadiene (2.80 %),
6-methyl-5-hepten-2-one (2.56 %), octan-1-ol (2.43 %), trans-geranyl acetone (2.17 %), trans-4,8-dimethyl-1,3,7-nonatriene
(1.98 %), phenyl methyl ketone (1.69 %), 6-methyl-3,5-heptadiene-2-one (1.57 %)
were the second most plentiful compounds found in POLs. 11H-dibenzo[b,e][1,4]diazepin-11-one,5,10-dihydro-5-[3-(methylamino)propyl]
(1.38 %), benzeneethanol (1.36 %) and β-ionone (1.02 %) were found as the third
most abundant VCs. The above-mentioned VCs were accounted for about 57 % of total
VCs identified in POLs. The remaining VCs were below 1.00 % that is, found at trace
levels. According to the VCs profiles of POL, its beneficial effects on health may
be due to aldehydes, alcohols, ketones and terpenes.
