It is considered that different plant organic compounds, known as phytoncides are creditable for positive effects of Forest therapy on human health. Ongoing pandemic has also put these compounds in research focus considering potential use for novel corona virus treatment. This research was conducted in order to examine the potential of Tilia cordata Mill. considering volatile organic compounds (VOCs) content for the use in Forest therapy. In order to determine qualitative and quantitative content of phytoncides, as well the variability among genotypes growing in the same environmental conditions, leaf samples from genotypes of T. cordata were collected from the Fruška gora (Serbia) during 2019. VOCs determined in fresh herbal material were analyzed by HeadspaceGC/MS and VOCs determined in essential oil were obtained by GC/MS. The results showed the presence of 17 different phytoncides (monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene hydrocarbons, oxygenated sesquiterpenes, aliphatic compounds and diterpenes) in all tested genotypes. According to the mean values of the obtained results, the most abundant classes of phytoncides among the examined genotypes were monoterpene hydrocarbons (87.05), followed by aliphatic compounds (36.59) and oxygenated sesquiterpenes (34.60). The highest coefficient of variation (CV) among phytoncide content in tested T. cordata genotypes has been observed within oxygenated monoterpenes (43.12%), sesquiterpene hydrocarbons (28.18%), and diterpenes (27.04%). Some individual monoterpene hydrocarbons, such as o-cymene (19.92%) and a-pinene (17.40%) had the highest CV in terms of its presence in analyzed genotypes. In addition, the principal component analysis (PCA) showed more notable clustering within the VOCs determined in essential oil in comparison to VOCs determined in fresh herbal material. Considering the phytoncide content detected in T. cordata leaves, this species has high potential for the use in human health improvement within Forest therapy.

Microextraction in solid phase from headspace and GC-MS analysis was the method of studying the flowers of Hypericum perforatum in fresh and dry form.The essential oil obtained by hydrodistillation was also analyzed by GC-MS. Identification of the substances was made by comparison of mass spectra with NIST library and standard alkanes were used for the calculation of the linear retention index. The identified compounds were grouped into classes of substances: monoterpene hydrocarbons, sesquiterpene hydrocarbons, oxygenated monoterpenes, oxygenated sesquiterpenes, non-terpene hydrocarbons. The main common constituents were as follows: caryophyllene, β-ocimene, α-pinene, β-pinene, octane-2-methyl. The abundance of the majority compounds, common to the three forms of the plant: essential oil,fresh, and dried plants, was compared.

Research was carried out in order to evaluate the effect of drought and salinity on Citrus aurantium L. plant physiological characteristics, total phenolic, flavonoid and ascorbic acid contents, and volatile organic compounds. C. aurantium plants were exposed to different levels of drought and salinity for an experimental period of 60 days. Moderate water deficit (MWD) and 100 mM NaCl increased significantly leaf total phenolic, flavonoid and ascorbic acid contents. Both drought and salinity promoted the accumulation of essential oil in leaves, while MWD and 100 mM NaCl resulted in the highest concentrations of essential oil. The main compounds of the essential oil were linalool, linalyl acetate, neryl acetate, geranyl acetate and α-terpineol. MWD and severe water deficit (SWD) reduced the concentration of hydrocarbon monoterpenes and promoted the accumulation of oxygenated compounds, while treatment with 50 and 100 Mm NaCl, promoted the accumulation of hydrocarbon monoterpenes and reduced oxygenated monoterpene concentrations in C. aurantium.

Volatile Organic Compounds (VOCs) have many sources, and they have effects on ecology and human health, which has aroused extensive attentions of many researchers. The Chinese and other countries studies in VOCs in atmosphere focused on detecting concentrations and compositions, sources apportionment, secondary pollutants transformation, health effects and other aspects. In the present paper, VOCs level in atmosphere, distribution characteristics and sources apportionment of VOCs in atmosphere were reviewed, the current studies results of VOCs in atmosphere were summarized.
