“…Thus, no constant composition of an EO can be expected. Different composition of an EO can lead to different bioactivity [57,59,60]. For the best prediction of EO activity the aromatogram should be performed with exactly the same EO used for therapy, meaning the same charge number.…”

Background: The yeast Malassezia pachydermatis is a commensal but also the most isolated pathogenic yeast in canine otitis externa. Essential oils (EOs) exhibit antimicrobial activity and thus could be an alternative for treatment of otitis. Objective: The aim of this study was to analyse the in vitro efficacy of EOs against M. pachydermatis isolates from canine ears. Materials and Methods: Twenty-two EOs were tested for their in vitro activity against 15 M. pachydermatis isolates by agar disc diffusion. In addition, diluted EOs were tested and volatile antifungal activity was analysed by vapour assay. Results: Most EOs showed in vitro efficacy against M. pachydermatis. A different susceptibility pattern of tested isolates was found. Overall, the most potential EO was lemon grass. Also, cinnamon leaf, clove, manuka, Indian melissa, oregano, palmarosa, and winter savory oil exhibited a strong antifungal activity. Volatile activity was proven by the inhibiting effect in vapour assay. Conclusion: EOs show in vitro activity against M. pachydermatis. This study gives scientific background for the use of EOs in veterinary medicine. Diverse susceptibility patterns of different M. pachydermatis strains emphasise the helpfulness of an aromatogram as one lead for the best choice of an EO for therapy. Antimykotische In-vitro-Wirksamkeit ätherischerÖle gegen Malassezia pachydermatis isoliert aus Hundeohren: Ein Bericht aus dem Routinelabor Schlüsselwörter Ätherische Öle · Malassezia pachydermatis · Otitis externa · Veterinärmedizin Zusammenfassung Einleitung: Der Hefepilz Malassezia pachydermatis gilt als Kommensale, ist aber gleichzeitig auch der am häufigsten isolierte Hefepilz bei caniner Otitis externa. Ätherische Öle könnten aufgrund ihrer antimikrobiellen Eigenschaften als alternative Therapie der Otitis verwendet werden. Zielsetzung: Ziel dieser Studie war die Untersuchung der antifungalen In-vitro-Wirksamkeit ätherischer Öle gegen M. pachydermatis-Isolate aus Hundeohren. Material und Methoden: Die In-vitro-Aktivität von 22 ätherischen Ölen wurde mittels Agar-Plättchen-Diffusionstest gegen 15 M. pachydermatis-Isolate untersucht. Zusätzlich wurden Verdünnungen der ätherischen Öle getestet und die volatile Wirkung mittels "vapour assay" analysiert. Ergebnisse: Die meisten ätherischen Öle zeigten in vitro eine Wirksamkeit gegen M. pachydermatis. Es konnte eine unterschiedliche Empfindlichkeit einzelner M. pachydermatis-Isolate gefunden werden. Lemongrasöl erwies sich als das po-tenteste ätherische Öl. Ebenfalls zeigten Zimtblätter-, Nelken-, Manuka-, indisches Melissen-, Oregano-, Palmarosa-und Bergbohnenkrautöl eine starke antifungale Wirksamkeit. Die volatile Wirkung konnte mittels "vapour assay" gezeigt werden. Schlussfolgerung: In vitro zeigen ätherische Öle eine Wirksamkeit gegen den Hefepilz M. pachydermatis. Diese Studie bietet eine wissenschaftliche Basis zur Anwendung ätherischer Öle in der Veterinärmedizin. Die unterschiedliche Empfindlichkeit der verschiedenen M. pachydermatis-Isolate gegenüber einzelner äther...

“…EOs at the flowering stage. The antioxidant activity of S. macrantha EOs is linked to the presence of the phenolic monoterpenes thymol and carvacrol and their precursor p-cymene which are able to scavenge different radical [36,53,68]. The highest antioxidant activity of the EO from the flowering stage is related to the concomitant presence of thymol and carvacrol which can act synergistically as radical scavengers [69] due to the presence of hydroxyl groups in their structures [70].…”

Essential oils (EOs) from medicinal and aromatic plants are interesting products to be used as natural food preservatives. The EOs from the genus Satureja are reported to inhibit foodborne pathogens being worthy of use as food preservatives. Satureja macrantha is found in Western and Northwest Iran and commonly used as a food flavoring agent and for the treatment of urinary diseases. The objective of the present study was to identify the chemical composition of S. macrantha EOs at different growth stages (vegetative, flowering and fruiting stages) and to evaluate their biological activities. Chemical compositions were analyzed using GC-FID and GC-MS. The antibacterial activity was evaluated using the broth microdilution method against the foodborne pathogenic bacteria Staphylococcus aureus (ATCC23922), Enterococcus faecalis (ATCC29212) (Gram-positive), Enterobacter aerogenes (ATCC13046) and Escherichia coli. The antioxidant activity was estimated using the DPPH, ABTS and reducing power assays. The yields of S. macrantha EOs were in the range of 1.4–1.8%, thus scalable for the manufacture of food preservatives on an industrial level. The main compounds of EOs were carvacrol (42.7–48.2%), thymol (0.2–16.5%), p-cymene (10.1–14.7%) and γ-terpinene (7.9–9.1%) in all phenological stages examined. The strongest antibacterial activity (MICs = 5–20 µg/mL) of the EOs was recorded in samples obtained during the flowering stage where carvacrol (42.7%) and thymol (16.5) were present both at high percentages. On the other hand, the antioxidant activity was found to be slightly higher in the other stages. As the EO obtained at flowering showed the best inhibitory properties against foodborne pathogenic bacteria, it is suggested that plants at this stage can be selected as main sources of food preservative agents.

“…It contains protein (6.3%), fat (5.1%), minerals (3.5%) and carbohydrates (69.4%) (Anjusha and Gangaprasad, 2014). The essential oil (5.8%) obtained by steam distillation of rhizomes contains a-phellandrene, sabinene, cineol, borneol, zingiberene and sesquiterpines (Zhang et al, 2017). Curcumin (diferuloylmethane) is the compound responsible for the yellow colour, and comprises curcumin I (94%), curcumin II (6%) and curcumin III (0.3%) (Xiang et al, 2018).…”

“…The major constituents in Curcuma aromatica rhizome consisted with 8,9-dehydro-9-formyl-cycloisolongifolene (2.7-36.8%), germacrone (4.3-16.5%), ar-turmerone (2.5-17.7%), turmerone (2.6-18.4%), curdione (50.6%), camphor (18.8-32.3%), xanthorrhizol (26.3%), arcurcumene (19.5%), di-epi-α-cedrene (16.5%), curcumol (35.8%), and 1,8-cineole (12.2%) (Tsai et al, 2011). Curcuma phaeocaulis rhizome has 8,9-dehydro-9-formylcycloisolongifolene (15.6-46.2%), germacrone (8.9-21.2%), and curlone (0.8-20.2%) as the main constituents (Zhang et al, 2017).
