Bouea macrophylla is a tree widely grown throughout South East Asia. It is used in folk medicine for the treatment of various illnesses. The present study aimed to identify the chemical constituents and to test the antimicrobial and anticancer activities of an ethanol extract from B. macrophylla leaves. The extract exhibited excellent antibacterial properties against 9 out of 10 target microorganisms. including four Gram-negative bacteria (Escherichia coli, Shigella flexneri, Vibrio cholera, and Pseudomonas aeruginosa) and four Gram-positive bacteria (Staphylococcus aureus, Listeria monocytogenes, Enterococcus faecalis, and Bacillus cereus), as well as a fungus (Candida albicans). In addition, the extract was also tested on HeLa and human colorectal carcinoma (HCT116) cells to evaluate its cytostatic effects. The ethanol extract was able to inhibit the proliferation of HeLa and HCT116 cells, showing IC50 = 24 ± 0.8 and 28 ± 0.9 µg/mL, respectively, whereas the IC50 values of doxorubicin (standard) were 13.6 ± 1.3 and 15.8 ± 1.1 µg/mL respectively. Also, we identified various bioactive compounds in the extract such as polyphenols, flavonoids, caryophyllene, phytol, and trans-geranylgeraniol by GC-MS, which could contribute to the extract’s biological activities. Therefore, our findings strongly indicate that the constituents of the B. macrophylla ethanol extract could be active against the tested bacteria and fungi as well as cancer cells. Further investigation is needed to understand the mechanisms mediating the antimicrobial and anticancer effects and identify signaling pathways that could be targeted for therapeutic application.

The genus Scorzonera comprises nearly 200 species, naturally occurring in Europe, Asia, and northern parts of Africa. Plants belonging to the Scorzonera genus have been a significant part of folk medicine in Asia, especially China, Mongolia, and Turkey for centuries. Therefore, they have become the subject of research regarding their phytochemical composition and biological activity. The aim of this review is to present and assess the phytochemical composition, and bioactive potential of species within the genus Scorzonera. Studies have shown the presence of many bioactive compounds like triterpenoids, sesquiterpenoids, flavonoids, or caffeic acid and quinic acid derivatives in extracts obtained from aerial and subaerial parts of the plants. The antioxidant and cytotoxic properties have been evaluated, together with the mechanism of anti-inflammatory, analgesic, and hepatoprotective activity. Scorzonera species have also been investigated for their activity against several bacteria and fungi strains. Despite mild cytotoxicity against cancer cell lines in vitro, the bioactive properties in wound healing therapy and the treatment of microbial infections might, in perspective, be the starting point for the research on Scorzonera species as active agents in medical products designed for miscellaneous skin conditions.

Although Hypericum species are best known as plants that produce hypericin and are used in folk medicine, their other chemical constituents are poorly understood. Polyphenolic secondary metabolites from whole plants of representative Korean Hypericum species ( H. laxum Koidz., H. erectum Thunb., and H. ascyron L.) were analyzed using a ultra performance liquid chromatography-quadrupole time-of-flight/mass spectrometry (UPLC-Q-TOF/MS)-based approach combined with unsupervised principal component analysis (PCA) multivariate analysis. On the loading scatter plot, significant changes in metabolites were found between species, and three flavonol glycosides (8: quercetin-3- O-galactoside, 12: kaempferol-3- O-glucoside, and 13: quercetin-3- O-rhamnoside) were evaluated as key markers among 17 isolated metabolites. The extracts of H. laxum Koidz. exhibited significant quenching effects on DPPH and ABTS radicals, with IC50 values of 10–20 μg/mL, and were slightly higher in total phenol (TP) and total flavonoid (TF) contents than other species. Additionally, anti-inflammatory activity was observed by reduced nitric oxide (NO) and interleukin-6 (IL-6) production from lipopolysaccharide (LPS)-stimulated macrophages (RAW 264.7 cells). This is the first study to report the presence of bioactive metabolites and their correlating biological activities in H. laxum Koidz.

Viburnum L., is one of the most diverse genera of Caprifoliaceae family. There are 4 species of this genus in Turkey. One of them is Viburnum opulus L. The fruits of V. opulus have been used as an antidiabetic in Turkish folk medicine and a traditional drink named “gilaburu” in Middle Anatolia. Oxidative stress is involved in the cell degenerative changes in the pathogenesis of a wide variety of human chronic diseases, such as cancer. Some of the studies carried out on the V. opulus extracts revealed the presence of phenolic acids, flavonoids, hydroxybenzoic acids, tannins, coumarins, cathechols, iridoid glycosides, antocyanins, and some others. Most of these polyphenols have various biological activities, including antioxidant, cancer chemopreventive, and anticancer activities. This study aimed to assess the in vitro antioxidant properties of the ethanol extract (VOE), decoction (VOD) and fruit juice (VOFJ) from the fruits of V. opulus against hydrogen peroxide (H2O2)-induced oxidative stress in human SH-SY5Y neuronal cells. Our study revealed that the VOE, VOD and VOFJ provided neuroprotection against H2O2-induced oxidative stress. In conclusion, VOE, VOD and VOFJ can be used as a functional dietary ingredient that might help in reducing health problems associated with various oxidative stress insults.

Propolis is a natural product made by honeybees that has been widely used in folk medicine with a broad spectrum of biological activities. To investigate the antidepressant-like activity of propolis extract, CD-1 mice were administered an ethanol extract of propolis (50, 100, or 200 mg/kg, p.o.) prior to the behavioral test. The propolis extract-treated group showed a dose-dependent decrease in immobility time in the FST and tail suspension test without altering locomotor activity. Propolis extract decreased the limbic hypothalamic-pituitary-adrenal axis response to the FST as indicated by an attenuated corticosterone response and decreased in c-fos immunoreactive neurons in the hippocampal dentate gyrus. Western blot analysis revealed a reduction in hippocampal glucocorticoid receptor (GR) expression following the FST, which was reversed by propolis extract. Propolis extract also increased pGR(S220)/(S234) ratio by a differential phosphorylation in S220 and S234. FST-induced downregulation of cAMP-responsive element binding protein phosphorylation at S133 (pCREB) was restored by propolis extract, showing a strong and positive relationship between pCREB and pGR(S220)/(S234) ratio. These findings suggest that the propolis extract potentiates antidepressant-like activity by enhancing GR function which is one of the therapeutic mechanisms of antidepressant; thus, propolis extract may provide a novel therapy for depression.
