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 essential oils of Blainvellea rhomboidea (Asteraceae) were obtained by hydrodistillation and analyzed by GC/MS and GC/FID. Initially, the essential oil from the aerial parts was investigated. From the 18 identified components, 5-indanol (14.5%) followed by p-cymen-8-ol (10.1%), β-caryophyllene (9.6%), caryophyllene oxide (9.6%), limonene (8.6%), terpinolene (7.8%), and spathulenol (7.7%) were the major constituents. The oil was tested against seven bacterial strains and the results showed significant antimicrobial activity. As a consequence, the essential oils from leaves and from flowers were analyzed separately. The major constituents of the leaf oil were terpinolene (21.2%), β-caryophyllene (19.2%), spathulenol (9.1%), caryophyllene oxide (7.4%), and bicyclogermacrene (7.1%), while the oil of the flowers contained terpinolene (28.1%), 5-indanol (16.3%), p-cymen-8-ol (15.3%) and limonene (14.7%) as prevalent compounds. The oils were tested against the same bacterial strains and the flower oil was the more active. These results indicated that the components of the essential oil from flowers seem to be responsible for the activity.

Varronia curassavica has anti-inflammatory properties because of the terpenes, α-humulene and β-caryophyllene, present in the essential oil. The objective of this study was to evaluate the influence of seasonality on the essential oil of V. curassavica accessions. Leaves from six accessions were collected from the Germplasm Bank of the Federal University of Minas Gerais over 12 months. Correlations between the essential oil content and meteorological factors were determined. Gas chromatography analysis coupled with mass spectrometry was conducted to determine the chemical composition of the essential oil. The content and chemical composition of the oil varied throughout the year. Relative humidity was correlated with accessions ICA-VC2 (-0.64) and ICA-VC4 (0.68). β-bourbonene, β-elemene, spathulenol, germacrene, caryophyllene oxide, α-humulene, and β-caryophyllene occurred in all accessions. Accession ICA-VC3 exhibited lower variation (22.17%), higher average (0.97%) essential oil, and maintained an average abundance of α-humulene greater than 2.6%, which is the amount necessary for phytotherapeutics.

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 Subject

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.
