The properties ofBoswelliaplants have been exploited for millennia in the traditional medicines of Africa, China, and especially in the Indian Ayurveda. In Western countries, the advent of synthetic drugs has obscured the pharmaceutical use ofBoswellia, until it was reported that an ethanolic extract exerts anti-inflammatory and antiarthritic effects. Frankincense was commonly used for medicinal purposes. This paper aims to provide an overview of current knowledge of the volatile constituents of frankincense, with explicit consideration concerning the diverseBoswelliaspecies. Altogether, more than 340 volatiles inBoswelliahave been reported in the literature. In particular, a broad diversity has been found in the qualitative and quantitative composition of the volatiles with respect to different varieties ofBoswellia. A detailed discussion of the various biological activities ofBoswelliafrankincense is also presented.

The essential oils were isolated by hydrodistillation from the hairy roots (HR) and roots of soil-grown plants (SGR) of Rhaponticum carthamoides and were analyzed by GC-MS method. In the both essential oils 62 compounds were identified. The root essential oils showed the differences in the qualitative and quantitative composition. The sesquiterpene hydrocarbons (55–62%) dominated in both essential oils. The major compounds of HR essential oil were cyperene, 13-norcypera-1(5),11(12)-diene, and cadalene while aplotaxene, nardosina-1(10),11-diene, and dauca-4(11),8-diene dominated in SGR essential oil. Both essential oils showed antibacterial activity especially against Enterococcus faecalis (ATCC 29212) and Pseudomonas aeruginosa (ATCC 27853) (MIC value = 125 µg/mL). HR and SGR essential oils also decreased the expression of IL-1β, IL-6, and TNF-α and the ROS level in LPS-treatment astrocytes. This is the first report to describe the chemical composition of R. carthamoides essential oil from hairy roots, its protective effect against LPS-induced inflammation and ROS production in astrocytes, and its antimicrobial potential. The results show that R. carthamoides hairy roots may be a valuable source of the essential oil and may be an alternative to the roots of soil-grown plants.

The steam distillation method was used to obtain samples of essential oil of some species of genus Agastache L. introduced in Belarus. More than 20 components have been identified and determined in the essential oils of Agastache pallidiflora ssp.neomexicana L., Agastache aurantiaca L., Agastache mexicana L., Agastache foeniculum L. by gas liquid chromatography.The quantitative composition of the samples of essential oils depends on the type of plant material. The main its components are limonene, 1.8-cineol, mentone, isomentone, methyl chavicol, methyeugenol. The main component of essential oils Agastache pallidiflora ssp. neomexicana L. и Agastache aurantiaca L is mentone (40–65 %). Essential oil Agastache foeniculum L. is enriched with pulegone and isomentone. Methyl chavicol and methyleugenol dominate in Agastache mexicana essential oil. Distribution of the enantiomers of limonene, menthone and pulegone are shown. Regardless of the plant species, the samples are optically pure in the (+)-pulegone. The nature of the distribution of the enantiomers of limonene and menthone is an individual characteristic of the studied Agastache L. essential oils.

Two different methods of coriander (Coriandrum sativum L.) essential oil isolation, steam distillation and extraction by methylene chloride (Soxhlet extraction) were investigated. After the determination of essential oil content in the investigated drug and in dry extract (using steam distillation), qualitative and quantitative composition of obtained essential oils, determined by TLC and GC-MS methods, were compared. The content of linalool was higher (52.4%) in essential oil obtained by coriander steam distillation than that in essential oil separeted from dry extract (42.8%), and, on the other hand, content of geranyl-acetate was lower (4.6% and 11.7%, respectively).

In order to increase the diversity of medicinal plants and biologically active compounds accumulated in them, considerable attention is given to introduction of Artemisia L. genus plants in Lithuania. The aim of our study was to determinate the qualitative and quantitative composition of essential oils of Artemisia pontica L. introduced in Lithuania. The object of investigation – Artemisiae pontici herba were prepared in the Scientific Sector of Medicinal and Aromatic Plants, Scientific Department of Botanical Garden at Vytautas Magnus University in 2018–2019. Essential oils were separated by hydrodistillation method, their composition was analysed by gas chromatography/mass spectrometry methods in the Faculty of Pharmacy at Lithuanian University of Health Sciences in 2018–2020. The obtained results showed that a statistically significant (p > 0.05) higher amount and diversity of compounds from Artemisiae pontici herba essential oils were assessed in 2018 when HTC = 1.32. A strong correlation (r = 0.740) was assessed between the average of active temperatures and precipitation in 2019. The content of compounds was by 33.3% lower when HTC = 0.91. The other major compounds were 1,8-cineole (46.86%), 1,4-cineole (37.92%) and camphor (29.41–33.02%).

The different methods of mentha extraction, such as steam distillation, extraction by methylene chloride (Soxhlet extraction) and supercritical fluid extraction (SFE) by carbon dioxide (CO J were investigated. SFE by CO, was performed at pressure of 100 bar and temperature of40?C. The extraction yield, as well as qualitative and quantitative composition of obtained extracts, determined by GC-MS method, were compared.

The composition of the volatile fraction of two important forage legumes from Italian sub-alpine N.E. pastureland, namely Trifolium pratense L. subsp. pratense (red clover) and T. repens subsp. repens (white clover) were investigated. The volatile oil was obtained from the fresh aerial parts by steam distillation and analyzed by GC/FID and GC/MS. The oil yield was 0.018 and 0.021% (weight/fresh weight basis) for T. pratense and T. repens, respectively. Several classes of compounds were found in both the oils, including alcohols, aldehydes, ketones, terpenes, esters, hydrocarbons, phenolics and acids. Qualitative and quantitative differences were found.
