“…Our results were in agreement with report by Ebrahimabad et al on chemical components of Stachys inflata Benth essential oil, linalool and terpinol were major components [21] . The result of chemical analysis of Stachys serotina (Host) Fritsch essential oil by Jerkovic et al showed that sesquiterpene hydrocarbons were the most abundant class of isolated volatiles of β-caryophyllene, δ-cadinene and α-humulene, germacrene D [34] .…”

“…The composition of the volatiles is known only for a few species; for example, studies proved that the volatile oil of members of S. lavandulifolia Vahl (sect. Zietenia) consists mainly of monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene hydrocarbons, oxygenated sesquiterpenes, diterpenoids and terpene esters [16][17][18][19][20][21][22][23] . The result of new study showed that the essential oil of Stachys mialhesi de Noé has antioxidant, antinociceptive and antiinflammatory effects in laboratory animals.…”

“…The essential oil showed inhibition of 93.9%, which was comparable with that of BHT (95.2%). Compounds containing hydrogen atoms (eugenol) in the allylic and/or benzylic positions give better activity in this test due to relatively easy abstraction of hydrogen atom from these functional groups by peroxy radicals formed in the test circumstances (Ebrahimabadi et al, 2010). The results of phenolic content assay showed that the essential oil possessed greater antioxidative properties with the value of 660.1 mg gallic acid/g (GA/g), and this is probably due to the high percentage of eugenol as the major component in the oil.…”

Context: The ethnopharmacological study of Beilschmiedia indicates that several species are used for the treatment of various ailments. Objective: This is the first study of the chemical composition of Beilschmiedia pulverulenta Kosterm (Lauraceae) essential oil and its antioxidant, antimicrobial, antityrosinase, antiinflammatory, and anticholinesterase activities. Materials and methods: The antioxidant activities were evaluated by b-carotene, 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, ferric-reducing antioxidant power (FRAP), and phenolic content at different concentrations. The antimicrobial activities against Gram-positive and Gram-negative bacteria and fungi were revealed by disk diffusion and microdilution. The antityrosinase and anti-inflammatory activities were assayed against mushroom tyrosinase and lipoxygenase enzymes. The anticholinesterase activity was analyzed using acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes. Results: Forty-two components were detected in B. pulverulenta oil with eugenol (45.3%) being the major component. The oil phenolic content and the FRAP were 660.1 mg gallic acid/g and 604.0 mg ascorbic acid/g, respectively. The oil gave an IC 50 value of 94.5 mg/mL and an inhibition of 93.9% in DPPH and b-carotene, respectively. The antimicrobial activity showed that the oil had strong activity against all Gram-positive bacteria with an minimum inhibitory concentration (MIC) value each of 62.5 mg/mL and moderate against all fungi with MIC and minimum bactericidal concentration (MBC) values each of 125 mg/mL. The oil showed significant antityrosinase and anti-inflammatory activities with 67.6 and 62.5% inhibition, respectively. In addition, the oil had moderate AChE (56.5%) and BChE (48.2%) activities. Discussion and conclusion: The results show that the oil could potentially be used for nutraceutical industries, food manufactures, and therapeutic agents against various diseases such as inflammation and rheumatism.

“…However, the composition varies strongly between origins [8]. Differences in chemical compositions can affect the biological activities of volatile oils, which include anti-inflammation [9], anti-fungal [10], antioxidant [11] and anticancer activities [12]. The present study mainly focused on the phytochemical analysis of the EOs from P. tobira flowers cultivated in China.…”

Abstract:Background: Pittosporum tobira (Thunb.) Aiton is an aromatic medicinal plant widely cultivated in the world. However, the essential oils (EOs) from P. tobira flowers for anti-cancer potential is still not systematically studied. The present aim to elucidate the phytochemical composition of the EOs and to explore mechanism of anticancer action. Methods: The EOs were extracted and analyzed by headspace solid-phase microextraction (HS-SPME) with gas chromatography-mass spectrometry (GC-MS). Volatile components were identified according to Kovats retention index (KI) and NIST database. The anti-neoplasm mechanisms of the EOs was comprehensively investigated in lung carcinoma A549 and H460 cells. Results: A total of 47 secondary metabolites representing 94.18% of the EOs were successfully identified: monoterpenes and sesquiterpenes were the dominant terpenoids. The EOs exhibited antiproliferative activity on A549 and H460 lung carcinoma cells.Hoechst 33324 fluorescent staining indicated the typical characteristics of apoptosis and induced cycle phase arrest. AnnexinV/PI staining revealed that the number of apoptotic cells was increased.Furthermore, the EOs also induced the caspase-mediated mitochondrial apoptosis pathway. Conclusions:Findings suggest that the full-scale chemical composition and first characterization of anticancer activities of the EOs, it could be used for integrative natural anti-cancer agents in health care should be pay more attention.
