“…The top three binding compounds, dibutyl phthalate (Ki = 24.22 μM), diisobutyl phthalate (Ki = 26.77 μM) and butyl octyl phthalate (Ki = 12.70 μM), which originate from the leaves of elms, were selected for further electrophysiological and behavioral tests. Other studies have shown that these compounds also occur among the volatiles of some other plants, such as Calycopteris floribunda 39 ; these three odorants could have all elicited strong EAG responses and had significant attractive effects on adult A. quadriimpressum . Because AquaOBP4 also binds to cinnamaldehyde, which is an antifeedant, AquaOBP4 binding might be correlated with host specificity.…”

In this study, the most abundant and antenna-specific odorant-binding protein (OBP) of the elm pest A. quadriimpressum, AquaOBP4, was expressed and purified. The selectivity of AquaOBP4 was investigated by screening against a panel of 40 habitat-relevant compounds. Based on the obtained results, a homologous model of AquaOBP4 was established. This model indicated that AquaOBP4 is highly homologous to DmelOBP LUSH and includes two main binding sites. A docking analysis showed that four of five active ligands bound at Site 1, whereas the other ligand was situated at Site 2. Furthermore, new ligands were docked in the model, and the results of fluorescence-based binding assays of these compounds were highly consistent with the binding conformation and binding affinity predicted by our model. Additionally, three binding odorants derived from elm leaves elicited a strong electroantennogram response and exerted a significant attractive effect on adult A. quadriimpressum. All of the results showed that AquaOBP4 is likely linked to the foraging behavior of A. quadriimpressum. This study provides a new reliable tool for future large-scale compound screenings and revealed several functional chemicals that might aid the development of a better pest management approach for A. quadriimpressum.

We evaluated the total phenolic acid content and antioxidant activity of methanolic and aqueous extracts of Calycopteris floribunda roots. Antioxidant activity of the extracts was determined using Reducing Power Assay and Total Antioxidant Capacity (TAC) assays. Preliminary phytochemical analysis of the extracts revealed the presence of various phytochemicals. The total phenolic content of the extracts was higher in methanol than compared to aqueous extracts and subsequently higher antioxidant activity was also observed in case of methanol extracts. The results revealed that the antioxidant activity of the extracts was positively associated with the total phenolic acid content.

“…In addition, the different chemical compositions and contents of alcohols and fatty acids is probably another important factor affecting the antimicrobial behaviour of oils. Some minor constituents in oils might also play a critical role in antimicrobial activity, possibly by producing a synergistic effect with other constituents (Liu et al 2009). At present, the mode of action of oils from Voacanga seeds on microorganisms is not fully understood.…”

In this study, essential oils from Voacanga africana seeds at different extraction stages were investigated. In the chemical composition analysis, 27 compounds representing 86.69-95.03% of the total essential oils were identified and quantified. The main constituents in essential oils were terpenoids, alcohols and fatty acids accounting for 15.03-24.36%, 21.57-34.43% and 33.06-57.37%, respectively. Moreover, the analysis also revealed that essential oils from different extraction stages possessed different chemical compositions. In the antioxidant evaluation, all analysed oils showed similar antioxidant behaviours, and the concentrations of essential oils providing 50% inhibition of DPPH-scavenging activity (IC50) were about 25 mg/mL. In the antimicrobial experiments, essential oils from different extraction stages exhibited different antimicrobial activities. The antimicrobial activity of oils was affected by extraction stages. By controlling extraction stages, it is promising to obtain essential oils with desired antimicrobial activities.
