To evaluate the antibacterial activity and chemical constituents of the essential oil from the artemisia argyi grown in Qichun (China). METHODS: Steam distillation method was used to extract volatile oil from Artemisia argyi. The antibacterial effect of the volatile oil was investigated by the plate coating method and the double gradient liquid dilution method. Gas chromatography-mass spectrometry(GC-MS) was applied for the identification of chemical constituents in volatile oil from Artemisia argyi and the relative percentage of each component was calculated by area normalization. RESULTS: The essential oil from artemisia argyi grown in Qichun (China) has significant antibacterial activity against staphylococcus aureus, pseudomonas aeruginosa, salmonella, candida albicans, aspergillus niger and aspergillus flavus. And fifty chemical components were detected in the essential oil, and twenty compounds were identified, accounting for 95.95% of total essential oil. And the artemisol in artemisia argyi grown in Qichun (China) was found to be the highest compared with the same species from other producing areas. CONCLUSION: The essential oil from artemisia argyi grown in Qichun (China) was a potent antibacterial plant extract with potential applications as an antibacterial drugs or food preservative.

Plant-based natural products represent an alternative to chemical compounds for the control of mites in veterinary medicine. Here, the essential oil of Elsholtzia densa (E. densa) Benth was extracted using hydrodistillation at a rate of 1.2%. The chemical composition of the essential oil was determined by gas chromatography-mass spectrometry (GC-MS) analysis. The GC-MS analysis indicated that the principal compounds in the volatile oil of the sample were 4-Pyridinol (28.16%) and thymol (26.58%). The acaricidal activity of E. densa oil against Sarcoptes scabiei (S. scabiei) was tested in vitro. Toxicity test data were analysed using a complementary log-log (CLL) model. The E. densa oil was prepared in five concentrations by dilution with liquid paraffin (1, 2, 4, 8 and 16 mg/ml) and exhibited strong toxicity against S. scabiei with LT<sub>50</sub> values of 16.637, 5.075, 2.884, 1.184 and 0.760 h, respectively. The LC<sub>50</sub> values were 7.678, 4.623, 2.543, 1.502, 1.298 and 0.981 mg/ml for S. scabiei at 1, 2, 4, 8, 16 and 24 h, respectively. Compared to the control, the essential oil showed significant effects against S. scabiei in vitro. At 16 mg/ml, E. densa oil was found to kill all mites within a 16-h period. The results indicate that E. densa oil possesses potential acaricidal activity in vitro and may be exploited as a novel drug for the effective control of S. scabiei.

AbstractThis study was aimed to determine the effect of different boron doses (boron free, pure boron with 8 liters per decare and in 1/8 ratio diluted boron) on the rate and quality of volatile oil in musk grown in Kütahya-Gediz conditions. Essential oil from Musk Sage was obtained by hydrodistillation method (GC-MS/FID). In the analysis carried out in 2017, the rate of essential oil was found to be 0.11% in the plant grown without boron, while it was 0.44% in the plant grown with pure boron. However, this rate was found as 0.23% in the 1/8 boron ratio application. The main components of volatile oil were found as follows: for the boron-free application—spathulenol 23.75%, caryophyllene oxide 19.41%, linalool 10.10%, and sclareoloxide 9.92%; for the pure dose application—spathulenol 26.67%, sclareoloxide 18.81%, and caryophyllene oxide 16.13%; for in 1/8 ratio diluted boron dose application—spathulenol 24.82%, sclareoloxide 16.68%, and caryophyllene oxide 14.86%. It has been observed that pure boron dose has a positive effect on the essential oil ratio and components of Musk Sage.

Background. Herba Siegesbeckiae (HS, Xixiancao in Chinese) is widely used to treat inflammatory joint diseases such as rheumatoid arthritis (RA) and arthritis, and its molecular mechanisms and active ingredients have not been completely elucidated. Methods. In this study, the small molecule ligand library of HS was built based on Traditional Chinese Medicine Systems Pharmacology (TCMSP). The essential oil from HS was extracted through hydrodistillation and analyzed by Gas Chromatography-Mass Spectrometer (GC-MS). The target of RA was screened based on Comparative Toxicogenomics Database (CTD). The key genes were output by the four algorithms’ maximum neighborhood component (MNC), degree, maximal clique centrality (MCC), and stress in cytoHubba in Cytoscape, while biological functions and pathways were also analyzed. The key active ingredients and mechanism of HS and essential oil against RA were verified by molecular docking technology (Sybyl 2.1.1) in treating RA. The interaction between 6 active ingredients (degree ≥ 5) and CSF2, IL1β, TNF, and IL6 was researched based on the software Ligplot. Results. There were 31 small molecule constituents of HS and 16 main chemical components of essential oil (relative content >1%) of HS. There were 47 chemical components in HS. Networks showed that 9 core targets (TNF, IL1β, CSF2, IFNG, CTLA4, IL18, CD26, CXCL8, and IL6) of RA were based on Venn diagrams. In addition, molecular docking simulation indicated that CSF2, IL1β, TNF, and IL6 had good binding activity with the corresponding compounds (degree > 10).The 6 compounds (degree ≥ 5) of HS and essential oil had good interaction with 5 or more targets. Conclusion. This study validated and predicted the mechanism and key active ingredients of HS and volatile oil in treating RA. Additionally, this study provided a good foundation for further experimental studies.
