Color Yield

This study mainly deals with the effect of hydrodistillation (HD) and water-steam distillation (WSD) methods on the color, yield, and chemical profile of the essential oil (EO) from Cryptomeria japonica fresh leaves from São Miguel Island (Azores Archipelago, Portugal). The yields of EO–HD (pale-yellowish) and EO–WSD (colorless) samples were 1.21% and 0.45% (v/w), respectively. The GC–FID, GC–MS, and 13C-NMR analyses of EO–HD vs. EO–WSD revealed (i) a high-content of monoterpenes (72.8% vs. 86.7%), mainly α-pinene (34.5% vs. 46.4%) and sabinene (20.2% vs. 11.6%), and oxygenated mono- and sesquiterpenes (20.2% vs. 9.6%); (ii) similar sesquiterpene (1.6% vs. 1.6%), β-myrcene (5.9% vs. 5.8%), and camphene (3.5% vs. 3.8%) contents; and (iii) significant differences in other classes/components: EO–HD is richer in oxygenated sesquiterpenes (17.1%, mainly elemol (10.4%) and α-eudesmol (3.4%)) and diterpenes (3%; mostly phyllocladene), while EO–WSD is richer in oxygenated monoterpenes (7.2%, mainly terpinen-4-ol (5.4%)), p-cymene (4.4%), and limonene (3.2%). Overall, the color, yield, and quantitative composition of the EO samples studied are strongly influenced by the distillation method. Nonetheless, this C. japonica leaf EO displayed a consistent α-pinene- and sabinene-rich composition. The same chemotype was found in a commercial Azorean C. japonica leaf EO sample, obtained by industrial steam distillation (SD), as well as in Corsica C. japonica leaf EO–HD. Furthermore, the bioactive composition of our EO samples revealed the potential to be used in green plant protection and in the medical, food, cosmetic, and household industries.

The objective of this study was to evaluate variations in leaf essential oil (EO) content and composition of Juniperus species in the Bighorn Mountains { J. communis L. (common juniper), J. horizontalis Moench. (creeping juniper), and J. scopulorum Sarg. (Rocky Mountain juniper)} in Wyoming, USA. The EO was extracted via steam distillation of fresh leaves (needles). The EO composition of the three Juniper species varied widely. Overall, the essential oil content of fresh leaves was 1.0% (0.4–1.8% range in different accessions) in J. communis, 1.3% (1.2 to 1.6% range) in J. horizontalis, and 1.1% (0.7–1.5% range) in J. scopulorum. The EO chemical profile of J. communis was very different from that of the other two species. The concentration of α-pinene in the oil was 67–80% in J. communis, 2.8–6% in J. horizontalis, and 2.3–13% in J. scopulorum. The concentration of sabinene was 57–61% of the oil of J. horizontalis and 13–59% in oil of J. scopulorum, whereas sabinene was either below 1% or not detected in J. communis. The oils of J. scopulorum and J. horizontalis had higher antioxidant capacity than that of J. communis. The oils of the three junipers did not show significant antimicrobial activity against 10 organisms. The diversity of the essential oil composition of these three junipers may encourage diverse industrial applications of Juniperus leaf essential oil.

ABSTRACT Piper bellidifolium, Piper durilignum, Piper acutilimbum and Piper consanguineum are bushes that occur in the Amazon and are morphologically similar. With the aim of analyzing the chemical profile of the volatile constituents of these species, essential oils from the leaves were obtained through steam distillation and analyzed using gas chromatography-flame ionization detection (GC-FID) and gas chromatograph coupled to a mass spectrometer (GC-MS). The chemical analysis enabled the identification of 95 compounds representing 96.3 ± 0.6% of the P. bellidifolium oil, 95.5 ± 0.71% of the P. durilignum oil, 98.0 ± 1.0% of the P. acutilimbum oil and 96.1 ± 2.1% of the P. consanguineum oil. Although sesquiterpenes were the predominant chemical class in the oils of the four species, qualitative and quantitative differences were found in their chemical composition. The major constituents were (E)-nerolidol (20.3 ± 0.4%) in the P. bellidifolium oil, germacrene D (11.1 ± 0.3%) in the P. durilignum oil, and γ-eudesmol in both the P. consanguineum (18.6 ± 0.5%) and P. acutilimbum (7.5 ± 0.4%) oils. Despite their morphological similarity, a principal component analysis (PCA) of the GC-MS data clearly separated the four species according to the chemical profile of the essential oil extracted from their leaves.

Background: Neuropathic pain is one of the contributors to the global burdens of illness. At present many patients do not achieve satisfactory pain relief even with synthetic pain-killers. Taking this into consideration, it is necessary to search for natural product-derived alternative treatment with confirmed safety and efficacy. Ageratum conyzoides L is a plant often used as analgesic in Indonesia, however, anti-neuropathic pain activity of this plant is still unknown. Objective: To determine the anti-neuropathic pain activity of the essential oil and non-essential oil component (distillation residue) of A. conyzoides L. Methods: We conducted separation of the essential oil component from other secondary metabolites through steam distillation. Both components were tested for anti-neuropathic pain activity using chronic constriction injury animal models with thermal hyperalgesia and allodynia tests. The animals were divided into 7 test groups namely normal, sham, negative, positive (pregabalin at 0.195 mg/20 g BW of mice), essential oil component (100 mg/kg BW), and non-essential oil component (100 mg/kg BW). Naloxone was tested against the most potent anti-neuropathic pain component (essential oil or nonessential oil) to investigate the involvement of opioid receptor. Results: The GC-MS of the essential oil component indicated the presence of 60 compounds. Meanwhile, non-essential oil components contained alkaloid, flavonoid, polyphenol, quinone, steroid, and triterpenoid. This non-essential oil component contained a total flavonoid equivalent to 248.89 ppm quercetin. The anti-neuropathic pain activity test showed significantly higher activity of the essential oil component compared to the non-essential oil component and negative groups (p<0.05). Furthermore, the essential oil component showed equal activity to pregabalin (p>0.05). However, this activity was abolished by naloxone, indicating the involvement of opioid receptor in the action of the essential oil component. Conclusion: The essential oil component of A. conyzoides L is a potential novel substance for use as anti-neuropathic pain.
