In the temperate zone live about 150 species of the Nepeta genus. Our investigations covered the examinations of the volatile oil containing species of the genus endemic in Hungary, Nepeta cataria and Nepeta parviflora. Latter is a relict of the ancient steppe-flora and endemic in Hungary as well. Phytochemical examination of the volatile oil containing plant material has also been carried out. Catnip growing in the Botanical Garden of PTE Department of Botany contained 0,67% volatile oil in May and 0,14% in November. Chemical character of the volatile oils were measured by gas chromatography/mass spectrometry and citronellol, citral-A, citral-B and geraniol components were identified. The composition of the oil of November samples shifted towards citronellol (65%). In both samples insecticide and repellent activity bearing compounds (+)-cis-p-menthane-3,8-diol, and (—)-trans-p-menthane-3,8-diol in 2-2.5 and 4-4.5% amount have been found. The catnip sample deriving from Germany contained a small amount of anetol, citronellol, neral, geraniol and geranial (6-13%), and possibly two isomers of nepetalactone in 23-31%. The Nepeta parviflora endemic in the Nagyvolgy valley near Nagykaracsony consisted of the same compounds in the investigated years (1998-2000). Its limonene, methyl chavicol, b-cariophyllene, b-selinene, b-cubebene, davanone, germacrene-D constituents have been identified. In the year 2000 different GC % of these compounds were detected in the different organs of the plants. The closely related species Nepeta cataria var. citriodora contained 83% citral, and the N. glechoma (= Glechoma hederacea) contained 41% a-cubebene, 20% patchoulenol, 7,7% spathulenol respectively. These compounds were identified by gas chromatography and gas chromatography / mass spectrometry.

The constituents of the volatile oil of Cunila polyantha from Dota, Costa Rica, were investigated using coupled gas chromatography-mass spectrometry (GC-MS) analyses. Menthone (63%), pulegone (14%), P-caryophyllene (4.5%) and 3-octanyl acetate (3%) were found to be the major constituents of the volatile oil.

The chemical composition of the essential oil of Pituranthos chloranthus ssp. cossonianus Maire (Apiaceae) was investigated by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) to reveal 54 compounds. The main constituents were myristicine (27.4%), limonene (15.8%), α-pinene (11.4%), and α-phellandrene (8.3%). The antibacterial activity of the oil was evaluated against several strains and was shown to be significant against Pseudomonas aeruginosa.

Volatile compounds from seven Salvia species and one interspecific hybrid growing at the Dallas Arboretum and Botanical Garden, Texas, US. Salvia coccinea, S. farinacea, S. greggii, S. leucantha, S. longispicata x farinacea, S. madrensis, S. roemeriana and S. splendens were investigated for their chemical compositions using a microdistillation technique. Volatiles were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). One hundred and twenty seven compounds were identified representing 94.3-99.7% of the oils. The major components in each of the seven species were as follows: S. coccinea ( Z)-3-hexenal (31%), viridiflorol (19%); S. farinacea 1-octen-3-ol (30%) and ( Z)-3-hexenal (23%); S. greggii 1,8-cineole (22%), borneol (17%), camphene (11%) and α-pinene (10%); S. leucantha limonene (35%) and α-pinene (17%); S. longispicata x farinacea 1-octen-3-ol (50%) and ( Z)-3-hexenal (24%); S. madrensis ( Z)-3-hexenal (53%); S. roemeriana limonene (49%) and α-pinene (20%); and S. splendens ( Z)-3-hexenal (36%), 2,5-dimethoxy- p-cymene (19%) and linalool (11%). The microdistillation method was fast, practical and a useful technique that enabled the isolation of the volatiles in samples when only limited quantities were available.

Two species of kunci pepet, i.e. K. angustifolia and K. rotunda (Zingiberaceae), had different aromas. We had been analyzed volatile oils of two species by gas chromatography-mass spectrometry (GC-MS). The volatile oils had been got by water-steam distillation. The GC chromatograms of K. angustifolia showed 16 compounds, 5 compounds of them was main compounds, i.e. cycloproazulene (21.86%), alloaromadendrene (20.79%), cyclopropnaphtalene (11.02%), (-)β-elemenene (16.00%), caryophyllene (16.00%), and isobornyl acetate (11.02%). The GC chromatograms of K. rotunda showed 10 compounds, 2 compounds of them was main compound, i.e. tetradecane (26.85%) and benzylbenzoic (55.46%). Based on chemical constituent of volatile oils, the two species of Kaempferia had similarity of 25.00-37.50%. Alloaromadendrene of K. angustifolia and benzylbenzoic of K. rotunda could be used to distinguish the two species of Kaempferia.

Keywords: populus ×berolinensis Dippel., leafs, compounds distilled with water vapor, gas chromatography-mass spectrometry Continuing the comprehensive pharmacognostic study of raw materials of plants of the genus Poplar, the aim of the study was to study the composition and content of compounds volatile with water vapor, Berlin poplar leaves (populus × berolinensis Dippel), which is widely cultivated in Ukraine. Raw materials for research were harvested from trees growing in the botanical garden of Kharkiv National University. V.N. Karazin (50 ° 01′46 ″ N 36 ° 14′02 ″ E.) in June 2019. It was found that the total content of compounds distilled with water vapor was 2026.4 mg / kg. 51 compounds were identified. Dominated by the content of: β-eudesmol (677.0 mg / kg), γ-eudesmol (234.0 mg / kg), α-bisabolol (125.9 mg / kg), eugenol (217.7 mg / kg), cubenol (92.3 mg / kg), quinesol (39.0 mg / kg). The obtained data indicate the prospects for further study of this type of raw material to assess the possibility of using it as a drug.

The aim of the studies was to determine the optimal term of harvest for Satureja montana L. (winter savory) in order to obtain the essential oil rich in antioxidative compounds such as carvacrol, p-cymene, γ-terpinene and β-caryophyllene. Essential oils of S. montanaaerial parts were obtained by hydrodistillation in Deryng-type apparatus and analyzed by gas chromatography/mass spectrometry (GC/MS). In total, 30 compounds were identified in the savory volatile oil under different harvesting terms (before flowering, during flowering and after the flowering), that represented 94.61 to 97.55% of the oils. The major components were carvacrol (65.43 to 69.99%), its precursors: p-cymene (3.69 to 9.69%) and γ-terpinene (1.51 to 5.92%) as well as β-caryophyllene (2.74 to 4.71%). Moreover, the term of harvest had a significant effect on the content of main essential oil constituents. The highest concentrations of carvacrol, γ-terpinene and β-caryophyllene were observed in the herb collected before flowering, while the highest amounts of p-cymene were noted after the flowering.
