Protium aracouchini (Aubl.) Marchand [sin Icica aracouchini Aubl.], which occurs in the Adolpho Ducke Forest Reserve, in the Brazilian Amazon, was evaluated for the presence of galls, for resin exudation and the composition of the essential oils from the aerial parts and the resin. The experiment to stimulate the exudation of resin from the trunk was conducted using a 2-chloroethylphosphonic acid solution. The resin produced after 40 days and the aerial parts had their essential oils extracted in a Clevenger apparatus and the volatile chemical constituents were analyzed using GC/MS. The non-oxygenated sesquiterpenes α-copaene (21.15%) and α-gurjunene (13.69%), in addition to the oxygenated sesquiterpene spathulenol (10.32%), were detected as the majority constituents of the essential oil of the leaves, and a concentration similar to that of α-gurjunene was found in the branches (13.28%). The resin essential oil showed a high concentration of hydrocarbon monoterpenes (76.49%) with a predominance of α-pinene (17.57%) and limonene (46.11%). Four gall morphotypes were found associated with this species. The present study reports for the first time information on the volatile constituents and the resinous potential of P. aracouchini, and registers the morphotypes of the galls that help in the taxonomy of the species.

Salvia leucantha Cav. (Lamiaceae), native to Mexico, is found in Venezuela in parks and gardens. Hydrodistillation of the fresh leaves of this plant yielded 0.05% of essential oil. GC and GC/MS analyses permitted the identification of 30 compounds, which made up 95.9% of the oil. The most abundant constituents were bornyl acetate (24.1%), β-gurjunene (14.8%), β-caryophyllene (14.1%), dillapiol (11.0%) and bicyclogermacrene (8.9%).

Important Constituent

Five batches of Bolivian Schinus molle essential oils were obtained from pilot and industrial-scale hydrodiffusions. They were analyzed by gas chromatography to find 80 known compounds and two unknown molecules. In particular, preisocalamendiol (5.6–11.0 %) was found to be an important constituent of these oils, along with shyobunol (0.6–3.2 %) and several other related oxygenated sesquiterpenes. These compounds, usually found in Acorus calamus, had not been reported altogether in S. molle essential oils previously. These findings, in light of the GABAA positive modulating effect of shyobunone and preisocalamendiol, along with some traditional uses of S. molle, suggest that further investigation of the tranquilizing properties of these Bolivian oils would be of interest.

The composition of the steam volatile constituents of leaf, fruit and bark of Neolitsea pallens (D. Don) syn. Litsea umbrosa var. consimilis Nees Hook f. syn. L. consimilis Nees were analyzed by GC, GC-MS and NMR spectroscopy. The major constituents of the leaf oil were furanogermenone (30.6%), β-caryophyllene (19.3%) and germacrene D (12.7%), while oxygenated sesquiterpenoids (83.6%) constitute the major proportion of the bark oil, which is dominated by furanogermenone (59.1%), germacrone (9.3%), 10- epi-γ-eudesmol (7.8%) and curcumenol (5.3%). The fruit oil was mainly composed of furanogermenone (54.8%), trans-β-ocimene (8.8%), sabinene (6.4%) and germacrene D (4.0%). The major constituents were isolated and characterized on the basis of NMR spectroscopic data. The furano sesquiterpenoids, the major constituents of N. pallens, are of chemosystematic and commercial importance.

Background and Aims: Acorus calamus L. is an indigenous herb in Nepal. It belongs to family Acoraceae and grows in wet land with scented rhizomes. It is also known as Sweet flag in English and commonly as Bojho in Nepal. The present investigation reveals the chemical compositions and antioxidant activity of rhizome essential oil of A. calamus. Methods: Essential oil of rhizomes of Acorus calamus L. from Kaski district, Nepal was extracted by hydrodistillation method and volatile constituents were analyzed Gas chromatography-Mass spectrometry. The antioxidant potential of essential oil was analyzed by 1,1-Diphenyl-2-Picrylhydrazyl (DPPH) scavenging assay. Results: A GC-MS analysis revealed the presence of β-asarone (22.38%), α-asarone (14.97%), 1-(4,6-dimethoxy-2,3-dimethylphenyl ethanone (14.24%), Isoelemicin (5.68%), cis-Methylisoeugenol (4.26%), α-calacorene (4.16%), and other 20 minor components. From DPPH assay, half maximal inhibitory concentration (IC50) value of essential oil was found to be 108.71 µg/mL. Conclusions: These findings have strengthened the A. calamus L. is good source of compounds like β-asarone, α-asarone and can be used as potential antioxidants. BIBECHANA 17 (2020) 89-95

The essential oil from the air dried powder of wild Acorus calamus L. rhizomes was isolated using Clevenger-type hydrodistillation apparatus and its chemical constituents were analyzed by gas chromatography-mass spectrometric (GC-MS) analysis. A total numbers of fourteen chemical constituents were identified and quantified occupying 100 % of total oil composition. The major chemical constituents are reported to be β-asarone (68.96 %), 4-hydroxy-4-methyl-2-pentanone (8.73 %) shyobunone (8.65 %), p-methoxyphenyl butanone (4.16 %) and the minor chemical constituents are δ-cadinene (0.84 %), isoelemicine (2.68 %), muurolene (1.92 %) and cis-ocimene (1.44 %). The antibacterial activity of the essential oil isolated from the wild Acorus calamus L. rhizomes was carried out using paper disc method against one Gram positive bacteria of Staphylococcus aureus and three Gram negative bacteria of Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris. The isolated essential oil from the dry powder of Acorus calamus L. rhizome showed a good potentiality of the antibacterial effect against tested bacteria.

Hydrodistilled essential oil and the corresponding headspace volatiles of Bosnian wild growing Thymus praecox ssp. polytrichus (A. Kern. Ex Borbàs) Jalas and Thymus praecox ssp. skorpilii (Velen.) Jalas were subjected to capillary GC-MS analysis. This work presents a detailed essential oil analysis of these two rare Thymus subspecies from Bosnia, as well as the very first report on their headspace composition. Eighty-seven volatile constituents were identified in four samples. Two alcohols were the major constituents in the essential oil of T. praecox ssp. polytrichus, a monoterpene, linalool (13.9%), and a sesquiterpene, ( E)-nerolidol (10.4%), while linalyl acetate (36.7%) and linalool (22.7%) were the most abundant volatiles in the corresponding headspace sample. Oxygenated monoterpenes (57.5%) predominate in the essential oil of T. praecox ssp. skorpilii with linalyl acetate (28.7%) and linalool (14.4%) as the main representatives. Headspace sample of this subspecies also showed richness in linalyl acetate (52.4%), while the second most abundant compound was α-pinene (14.5%), a monoterpene hydrocarbon.
