The genus Lavandula includes a variety of species under the common name lavender. Bulgaria has a tradition in the production of high-quality lavender oil. This is the result of many years of selection work, which includes the study of introduced samples and their adaptogenic abilities in the country habitat. Three samples of Lavandula angustifolia Mill., that originated from Poland were studied and compared with the Bulgarian varieties “Hemus” and “Sevtopolis”. The content of the essential oils ranged from 0.39% to 3.98%. The chemical composition, determined by GC/MS, revealed the main compounds: linalyl acetate (13.0÷44.9 %), linalool (21.8÷42.1%), β-caryophyllene (4.6÷7.4 %), cis-β ocimene (2.8÷10.5 %), lavandulyl acetate (1.9÷4.3%), terpinen-4-ol (0.3÷2.0 %), limonene+1.8 cineole (2.3÷6.0 %) and trans-β ocimene (0.1÷3.8%). The sample with the dark purple florescence showed promising quantitative and qualitative characteristics of the essential oil and can be involved in the selection program for lavender cultivation.

Herb Species

The restinga is an Atlantic Forest ecosystem characterized by tree, shrub, and herb species that are rich sources of essential oils. In this study, we aim to quantify the essential oil content and determine the chemical constituents of fresh leaves of 14 plant species in a restinga stretch in southern Brazil. Essential oils were obtained by hydrodistillation in a Clevenger-type apparatus and analyzed by gas chromatography coupled to mass spectrometry. Campomanesia reitziana, Cortaderia selloana, and Sophora tomentosa had no essential oils. Total essential oil content ranged from 0.01% (Mikania involucrata) to 1.56% (Varronia curassavica). In total, 60 chemical constituents were identified, representing between 46.2% and 96.5% of the chemical composition of the essential oils. Limonene was the common constituent in all species in which the essential oils were present. The major constituents were ar-curcumene (15.1%) and cis-chrysanthenol (14.2%) in Ambrosia elatior; benzyl benzoate (43.5%) and benzyl salicylate (23.7%) in Aniba firmula; caryophyllene oxide (35.7%) and spathulenol (10.6%) in Austroeupatorium inulaefolium; spathulenol (19.8%) and caryophyllene oxide (14.0%) in Baccharis spicata; caryophyllene oxide (16.3%) in Eugenia astringens; curzerene (30.0%), limonene (13.0%), and germacrone (11.9%) in Eugenia uniflora; caryophyllene oxide (17.1%) and ledol (11.3%) in Lantana camara; caryophyllene oxide (27.7%) and limonene (12.7%) in M. involucrata; 1,8-cineole (19.8%) in Psidium cattleianum; limonene (10.2%) in Schinus terebinthifolius, and allo-aromadendrene (15.2%) in V. curassavica. We expect that our results can assist in selecting species of potential interest for herbal, phytotherapeutic, and cosmetic products.

ABSTRACT: Campomanesia adamantium is a native fruit species of the Cerrado and is used in food and medicines and as bee pasture. The chemical composition of essential oils obtained from plants of the same species have varying constituent proportions due to the influence of extractive factors, environmental, genetic and ontogenetic. This study aimed to identify the influence of hydrodistillation time on the content and chemical composition of essential oil extracted from the leaves of C. adamantium . Treatments consisted of five extraction times (1, 2, 3, 4, and 5h) using Clevenger with five replications in a completely randomized design. It was observed that after two hours of hydrodistillation, the essential oil content remains constant. Regarding the chemical constituents of essential oil, variation of the proportions of the compounds tested occurred at all hydrodistillation times. The compounds spathulenol oxygenated sesquiterpenes and caryophyllene oxide were the majority in the five hydrodistillation times.

The volatile chemical composition of leaf essential oils of three Annona species (Annona cherimola, Annona muricata and Annona squamosa) from the different regions of Kerala, South Indian was determined using gas chromatography-mass spectrometry analysis. A total of 41 constituents belonging to monoterpenoids, sesquiterpenoids and diterpenoids were identified. Monoterpenes and sesquiterpenoids were the major class of volatile compounds in most of the Annona species examined. The study led to the identification of major compounds as germacrene D (23.5%), bicyclogermacrene (14.6%) and β-caryophyllene (11.7%) in A. cherimola, α-pinene (13.3%), β-caryophyllene (11.2%) and β-pinene (10.1%) in A. muricata, and β-caryophyllene (11.9%) and α-pinene (8.2%) in A. squamosa respectively. The examined essential oils showed that β-caryophyllene is the common constituent identified in all the three species and other constituents are more specific for each species under study. Present investigation reports, a comparison of essential oil compositions of three Annona species from Kerala. Results of this study prove that essential oils examined have considerable dissimilarity in chemical composition with previously reported leaf essential oil compositions from other regions. A chemotaxonomic analysis of these essential oils based on the distribution of compounds has revealed an efficient method to differentiate Annona species unambiguously.

The experiment was conducted in the Botanical Garden of UMCS in Lublin. A collection of three ecotypes of <i>Allium ursinum</i> L. from Dukla, Roztocze Region and Bieszczady mountain range, were the subject of our study. The aim of the study was to compare the biometrical features and chemical composition of garlic leaves. There were substantial differences both in growth characteristics and flowering characteristics of the ecotypes of <i>Allium ursinum</i>. The Dukla ecotype formed the longest leaves, whereas the shortest ones were found in the Roztocze ecotype. The Bieszczady ecotype was characterized by the widest leaf blades, the longest leaf stalk and flowering stems as well as the largest diameter of inflorescence. The Roztocze ecotype had the largest number of flowers in an inflorescence, while the Dukla ecotype had the shortest flowering stems and the fewest flowers in an inflorescence. The largest concentration of dry mass in leaves was detected in <i>A. ursinum</i> from Roztocze. The largest concentration of proteins was detected in the leaves of <i>A. ursinum</i> from Bieszczady. The most flavonoids were assayed in the leaves of the Roztocze ecotype of <i>A. ursinum</i>, the fewest in the Dukla one. Phenolic acids were at their highest concentration in the leaves of bear's garlic from Dukla, while the lowest concentration was recorded in the leaves of the ecotype from Bieszczady. The garlic leaves from Dukla had also the highest content of essential oil, while the Roztocze ones had the lowest oil content. The ecotypes of <i>Allium ursinum</i> differed substantially when it comes to the number of components of their essential oils and the amount of selected components.

Psidium guajava L. is native to Central and South America. It is widely distributed and well adapted to Brazil, a producer of essential oils rich in terpenes. The objective of this study was to evaluate the effects of natural and artificial drying on the content and chemical composition of the essential oil of guava leaves (Psidium guajava L.) grown in Rio Verde (GO). The two treatments consisted of drying fresh leaves either naturally in the shade or artificially at 40°C. Chemical composition was analyzed qualitatively and quantitatively by gas coupled with mass spectrometer chromatography (GC/MS) and gas chromatography using a flame ionizer (GC-FID), respectively. The method of drying changed the content and chemical composition of the essential oil of guava leaves. Drying in the shade reduced the content and altered the constituents of the essential oil, whereas drying in an oven at 40°C, despite having reduced the amounts of the constituents, exhibited the highest essential oil content and increased the concentration of certain major constituents as compared to that in the natural shade drying method. The major components found in the essential oil of leaves regardless of the drying processes were trans-caryophyllene, ?-humulene, aromadendrene, ?-selinene, and selin-11-en-4?-ol. According to reports in the literature, these compounds possess fungicidal, insecticidal, antimicrobial, and anti-inflammatory activity, among others beneficial actions.

Aims: The cultivation of medicinal plants in intercropping with other species of agricultural use has been an alternative to make production sustainable in family farming. The objective of this work was to evaluate the growth, biomass production, and chemical composition of the essential oil of mint (Mentha x gracilis Sole) in intercropping with fruit species in an agroforestry system. Study Design:  The experimental design was randomized blocks with four treatments, mint interplanted with citrus (Citrus sinensis L. Osbeck), bananas (Musa spp.), blackberries (Morus nigra), or Barbados cherries (Malpighia glabra). Place and Duration of Study: The experiment was conducted in the agroforestry located in the sector of Olericultura of the Federal University of Technology – Paraná (UTFPR), Brazil, in the period between November 2015 to February 2017. Methodology: We analyzed light intensity, relative chlorophyll index, height, leaf area, biomass accumulation, essential oil content, oil production and chemical composition of mint grown in agroforestry. Results: The highest production of biomass and essential oil were obtained in the intercropping of mint with citrus and Barbados cherries, possibly due to the edaphic climatic conditions, such as greater light intensity, that favored the growth, production, and chemical composition of the mint essential oil. Bananas and blackberries intercropped with mint were not beneficial for the growth and production of essential oils. Conclusion: The intercropping of mint with citrus and Barbados cherries resulted in higher growth, biomass accumulation, and essential oil content and production. The major components of the essential oils were linalool and carvone, with higher percentages in the intercropping of mint with citrus and Barbados cherries. The cultivation of mint by intercropping with fruit species such as citrus and Barbados cherries is an option to diversify the production of medicinal plants, making it sustainable.

The essential oil of Lavandula stoechas was examined by GC and GC-MS. Discs (5 mmi.d.) of the tested fungi ( Alternaria alternata, Fusarium oxysporum and Botritys cinerea) were inoculated separately onto each assay plate and incubated at 25oC for 7 days. The oil yield of dried parts (v/dw) obtained by hydro-distillation was 2.9%. Thirty-two compounds representing 98.3% of the essential oil were determined. Linalool (49.9%), linalyl acetate (14.4%), lavandulyl acetate (5.7%), α-terpineol (5.6%), terpinene-4-ol (5.1%), lavandulol (3.7%), ( E)-β-ocimene (2.6%) and ( Z)-β-ocimene (2.4%) were identified as the main constituents of the oil. In addition, both doses of the lavender oil showed varying levels of inhibitory effects on the mycelial growth of tested fungi used in the experiment. The results demonstrated the strongest effect on B.cinerea, followed by A.alternata and F.oxysporum. The inhibitory effect is probably dependent on the concentration of essential oils.

In this research, the variations in the chemical composition of the Lavandula angustifolia Mill. essential oil, the Romanian variety Moldoveanca 4, obtained from the same culture, in the same harvesting and extraction conditions, during the years 2016-2018, representing the years 2-4 of culture. Lavandula angustifolia Mill. flowers were supplied from an ecological-crops from N-E Romania and the essential oils were obtained by hydro distillation of freshly harvested flowers. To determine the chemical composition, the essential oil was semi-quantitatively analysed by using gas chromatography coupled with mass spectrometry (GC-MS). In all the samples, 30 organic compounds were identified, linalool and linalyl acetate being in similar concentrations (23.51-27.39% for linalool and 26.60-40.66% for linalyl acetate). Changes in chemical composition were observed in 2017 and 2018. Also, in 2017 was determined an increase in the quantity of linalyl acetate (from 26.60 to 40.66 %), and a slight decrease in linalool content; in 2018, the concentration in linalyl acetate remained approximately the same as in 2017 (38.03 versus 40.66 %) and there was an increase in linalool compared to the previous years (27.39 %, compared to 23.51 % in 2017 and 26.22 % in 2016). The chemical composition of the essential oils obtained from flowers of Lavandula angustifolia L., Moldoveanca 4 variety, showed substantial changes of the chemical profile describing the compounds during the analysed three years, as was determined by GC-MS analyses.
