“…The maximum and minimum concentrations of these compounds were observed in the extracts prepared from the aerial parts of the plant collected at the flowering stage and the root collected at the same stage, respectively, and this was coincident with the behavior of the total contents of phenolics, flavonoids, alkaloids, and saponins. Several studies report the antioxidant, antibacterial, and anti-inflammatory activity of these constituents [ 44 , 45 , 46 ]. Kerbouche et al [ 47 ] analyzed the essential oils and ethanolic extracts of the T. polium plant, in which t-cadinol (18.3 %), germacrene D (15.3 %), and β-pinene (10.5 %) were the main compounds.…”

The aim of the present study was to investigate the changes in the content of phytochemical compounds and in vitro antioxidant, antibacterial, and anti-inflammatory activities of Teucrium polium L. aerial parts and root methanolic extracts at different phenological stages (vegetative, flowering, and seeding). The T. polium extracts were analyzed using gas chromatography–mass spectrometry (GC-MS), and their antioxidant properties were tested with the 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide (NO), ferrous ions (Fe2+), and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) methods. Forty-nine compounds were identified with the majority of germacrene D, t-cadinol, β-pinene, carvacrol, bicyclogermacrene, α-pinene, and limonene. The results show that the extracts significantly differ between different phenological stages of the plant material used in terms of the phytochemical composition (total phenolic compounds, total flavonoids, total alkaloids, and total saponin contents) and bioactivities (antioxidant, antibacterial, and anti-inflammatory) (p < 0.05). The highest total contents of phenolics (72.4 ± 2.5 mg gallic acid equivalent (GAE)/g dry weight), flavonoids (36.2 ± 3.1 mg quercetin equivalent (QE)/g dry weight), alkaloids (105.7 ± 2.8 mg atropine equivalent (AE)/g dry weight), and saponins (653 ± 6.2 mg escin equivalent (EE)/g dry weight), as well as antioxidant, antibacterial, and anti-inflammatory activities, were measured for the extract of the aerial parts obtained at the flowering stage. The minimum inhibitory concentration (MIC) values for the extracts were varied within 9.4–300 µg/mL, while the minimum bactericidal concentration (MBC) values were varied within 18.75–600 µg/mL. In addition, they were more active on Gram-positive bacteria than Gram-negative bacteria. The data of this work confirm that the T. polium extracts have significant biological activity and hence can be used in the pharmaceutical industry, clinical applications, and medical research, as well as cosmetic and food industries.

“…The chemical profile of the essential oils of specimen M. multiflora was characterized by hydrocarbon and oxygenated sesquiterpenes, and studies on the essential oils of the Myrcia genus have proven strong the presence of these classes of compounds, as described in two chemical types presented by the essential oils of two specimens of M. tomentosa . Type (A) was characterized by γ-elemene (12.52%), germacrene D (11.45%) and ( E )-caryophyllene (10.22%), while type (B) was characterized by the major compounds spathulenol (40.70%), α-zingiberene (9.58%) and γ-elemene (6.89%) [ 36 ] ( Table 1 ).…”

“…The HCA was carried out by adopting the similarity using Euclidean distance through a 4 × 28 correlation matrix, and the PCA was carried out using the covariance matrix of the samples since all input data were presented as the mass percentage (≥2%). Both HCA and PCA were carried out using all the identified compounds as variables [ 36 , 69 ].…”

“…On the other hand, in the essential oil of E polystachya, germacrene D (18.4%), ishwarane (15.7%), 7-epi-α-selinene (7.5%) and bicyclogermacrene (5.1%) predominated [41]. The compounds γ-elemene (25.89%), germacrene B (8.11%) and (E)-caryophyllene (10.76%) were the main compounds of the essential oil of E. patrisii studied by [36], in which, on the other hand, the γ-elemene content was higher than that found in our study. This hydrocarbon sesquiterpene is reported in essential oil research for its antimicrobial and antiproliferative action [42], while the compound seline-3,11-dien-6-α-ol is described in the literature as a possible insecticidal agent [43] and antioxidant [44].…”

The essential oils of three specimens of Myrcia multiflora (A, B and C) and Eugenia florida were extracted by hydrodistillation, and the chemical compositions from the essential oils were identified by gas chromatography and flame ionization detection (CG/MS and CG-FID). The fungicide potential of the EOs against five fungicide yeasts was assessed: Candida albicans INCQS-40175, C. tropicalis ATCC 6258, C. famata ATCC 62894, C. krusei ATCC 13803 and C. auris IEC-01. The essential oil of the specimen Myrcia multiflora (A) was characterized by the major compounds: α-bulnesene (26.79%), pogostol (21.27%) and δ-amorphene (6.76%). The essential oil of the specimen M. multiflora (B) was rich in (E)-nerolidol (44.4%), (E)-γ-bisabolene (10.64%) and (E,E)-α-farnesene (8.19%), while (E)-nerolidol (92.21%) was the majority of the specimen M. multiflora (C). The sesquiterpenes seline-3,11-dien-6-α-ol (12.93%), eremoligenol (11%) and γ-elemene (10.70%) characterized the chemical profile of the EOs of E. florida. The fungal species were sensitive to the essential oil of M. multiflora (B) (9–11 mm), and the lowest inhibitory concentration (0.07%) was observed in the essential oil of M. multiflora (A) against the yeasts of C. famata. Fungicidal action was observed in the essential oils of M. multiflora (A) against C. famata, with an MIC of 0.78 µL/mL and 3.12 µL/mL; C. albicans, with an MFC of 50 µL/mL and M. multiflora (C) against C. albicans; and C. krusei, with a MFC of 50 µL/mL.

“…In addition, the Myrtaceae species are essential oil-producers which show a chemical variability of cyclic mono- and sesquiterpenes, composed by p -menthane, pinane, bisabolane, germacrane, caryophyllane, cadinane, and aromadendrane skeletons in Psidium genus [ 4 ], and caryophyllane, germacrane, and pinane in Eugenia and Syzygium genera [ 5 ]. Myrtaceae essential oils have many applications in the pharmaceutical, food, and cosmetic industries because of their antifungal, antibacterial, cytotoxic, and insecticidal properties [ 6 ].…”

Myrciaria (Myrtaceae) species have been well investigated due to their chemical and biological relevance. The present work aimed to carry out the chemotaxonomic study of essential oils of the species M. dubia, M. floribunda, and M. tenella, sampled in the Brazilian Amazon and compare them with the volatile compositions from other Myrciaria species reported to Brazil and Colombia. The leaves of six Myrciaria specimens were collected (PA, Brazil) during the dry season, and their chemical compositions were analyzed by gas chromatography-mass spectrometer (GC-MS) and gas chromatography-flame ionization detector (GC-FID). The main compounds identified in the essential oils were monoterpenes with pinane and menthane skeletons, followed by sesquiterpenes with caryophyllane and cadinane skeletons. Among the sampled Myrciaria specimens, five chemical profiles were reported for the first time: profile I (M. dubia, α-pinene, 54.0–67.2%); profile II (M. floribunda, terpinolene 23.1%, α-phellandrene 17.7%, and γ-terpinene 8.7%); profile III (M. floribunda, γ-cadinene 17.5%, and an unidentified oxygenated sesquiterpene 15.0%); profile IV (M. tenella, E-caryophyllene 43.2%, and α-humulene 5.3%); and profile V (M. tenella, E-caryophyllene 19.1%, and caryophyllene oxide 41.1%). The Myrciaria chemical profiles showed significant variability in extraction methods, collection sites, plant parts, and genetic aspects.
