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 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.

Lippia gracilis, popularly known in Brazil as ‘alecrim-de-tabuleiro’, is used for many purposes, especially as antimicrobial and antiseptic. The drying process of aromatic and medicinal plants aims to minimize the loss of active principles and slow their deterioration, which may greatly influence the yield and chemical composition of some species. The objective of this study was to evaluate the effect of drying times (0, 2, 4, and 8 days) on the content and chemical composition of the essential oil of L. gracilis accessions LGRA-106, LGRA-109, and LGRA-201. The leaves were dried at 40 oC, and essential oil was extracted by hydrodistillation. Chemical analysis was performed by GC/MS. The experiment was carried out in a completely randomized design with three replications. The accessions of L. gracilis LGRA-106, LGRA-109, and LGRA-201 presented higher essential oil at four days of drying time. The accession LGRA-201 showed the highest essential oil yields at four and eight days of drying, with mean values of 0.038 and 0.029 mL g-1, respectively. The drying time did not influence the contents of thymol, methyl-thymol, γ-terpinene, and carvacrol in the essential oils of L. gracilis, but affected the contents of β-caryophyllene, p-cymene, and carvacrol acetate. The essential oils of the three accessions analyzed in this study revealed different chemical profiles.

Alpinia Zerumbet

Alpinia zerumbet is an aromatic and medicinal plant rich in essential oil, known as colônia. Essential oils are derived from secondary metabolism and may be a source of raw materials for cosmetic, pharmaceutical, food and perfumery industry. The plant secondary metabolism and biosynthetic activity can vary according to endogenous and exogenous factors to which it is exposed. In this context, in this study we evaluated the influence of harvest time and plant age of Alpinia zerumbet on biomass and essential oil production. For the harvest time experiment the plants of A. zerumbet were harvested at different times (8, 10, 12, 14, 16 and 18 h), using a completely randomized design with four replications. In the plant age experiment the seedlings were propagated by division of rhizomes and grown in a completely randomized design with treatments consisting of four ages (3, 6, 9 and 12 months after transplanting), with seven replications. The extractions of the essential oil were performed by oil hydrodistillation in Clevenger apparatus and chemical analysis by gas chromatography coupled with mass spectrometry (CG-MS). There was an effect of harvest time on the essential oil content with the highest value (0.48%) found at 14:33 h with no change in the chemical composition. In relation to plant age, there was a significant increase in aboveground biomass of plants, accompanied by increases in height, number of shoots, and essential oil content and yield. The major compound terpinen-4-ol was present in higher concentrations in plants harvested between six and nine months old.

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 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.
