RESUMEN
Oliveria decumbens is a folkloric medicinal plant belonging to the Apiaceae family, traditionally utilized to treat various diseases like gastrointestinal disorders, fever, and wounds. This review aims to provide a comprehensive overview of the plant's phytochemical composition and biological properties, with potential implications for various industries and avenues of further research. The data presented here has been compiled through searches utilizing the keyword "Oliveria" across scientific databases such as PubMed, Web of Science, Scopus, ScienceDirect, and SciFinder. Carvacrol and thymol have been identified as the primary volatile constituents, though the complete profile of the plant extract remains to be fully elucidated. Notably, Oliveria decumbens essential oil exhibits significant antibacterial, antifungal, antioxidant, and anticancer properties. Additionally, the plant extract demonstrates promising antiprotozoal, antiviral, hepatoprotective, and immunostimulant effects, although these findings are primarily derived from preliminary studies. While inâ vitro and inâ vivo investigations have validated some traditional uses of O. decumbens, further pre-clinical testing is warranted to ascertain both efficacy and safety profiles. Moreover, the identification of specific components within the plant extract is crucial for a more comprehensive understanding of the mechanisms of action underlying its therapeutic properties within the realm of phytomedicine.

Many flavonoids, as eminent phenolic compounds, have been commercialized and consumed as dietary supplements due to their incredible human health benefits. In the present study, a bioactive flavone glycoside linarin (LN) was designated to comprehensively overview its phytochemical and biological properties. LN has been characterized abundantly in the Cirsium, Micromeria, and Buddleja species belonging to Asteraceae, Lamiaceae, and Scrophulariaceae families, respectively. Biological assessments exhibited promising activities of LN, particularly, the remedial effects on central nervous system (CNS) disorders, whereas the remarkable sleep enhancing and sedative effects as well as AChE (acetylcholinesterase) inhibitory activity were highlighted. Of note, LN has indicated promising anti osteoblast proliferation and differentiation, thus a bone formation effect. Further biological and pharmacological assessments of LN and its optimized semi-synthetic derivatives, specifically its therapeutic characteristics on osteoarthritis and osteoporosis, might lead to uncovering potential drug candidates.
RESUMEN
The rare genus Ducrosia (Apiaceae family) consists of six species, which are mainly native to Asia, specifically to Iran and Iraq. The aerial parts of D. anethifolia, as the most common species, have been traditionally consumed to relieve headache, backache and colic pain, and have also been used as an anxiolytic, an antidepressant, and for treating insomnia. The antispasmodic and carminative effects of D. assadii, and the analgesic activity of D. flabellifolia, along with the insecticidal activities and use as a remedy of skin infections of D. ismaelis, have been previously documented. Among the 49 non-volatile secondary metabolites identified from D. anethifolia and D. ismaelis, 17 linear furanocoumarins and 8 flavonoids have been characterized. The essential oil compositions of four species, including D. anethifolia, D. assadii, D. flabellifolia and D. ismaelis, have been analyzed, whereby aldehyde hydrocarbons, including decanal (10.1â74.0%) and dodecanal (7.2â33.41%), and α-pinene (4.0â70.3%), were identified as the main aroma constituents. From the species of the genus, the bioactivities of D. anethifolia, as well as D. ismaelis, D. assadii and D. flabellifolia, have been previously investigated. Except one clinical trial, all the pharmacological data are derived from preclinical tests, predominantly focusing on antimicrobial, antioxidant, antiproliferative and cytotoxic activities in vitro, and neuroprotective, antidiabetic and analgesic effects in vivo. Considering the vast ethnobotanical uses of the plants in Iranian folk medicine, the phytochemical and pharmacological analysis of un-investigated species might be promising. Furthermore, due to extensive consumption of the Ducrosia genus, more scientific data are needed to support the safety and efficacy of these plants.
RESUMEN
To evaluate the fluctuation of secondary metabolites in Arabian lilac during a year, aerial parts of the plant were harvested in the middle of each month. The essential oils content from fresh and dried plant materials was analyzed by gas chromatography-flame ionization detector (GC-FID) and gas chromatography-mass spectrometer (GC-MS), individually. Phytochemical contents, along with antiradical scavenging potential of the related methanol extracts were separately assessed. The spring and autumn samples (fresh and dried) yielded more essential oil than the other samples. Forty-one compounds were identified totally in the oils and the major constituents characterized were ß-caryophyllene, sabinene, and caryophyllene oxide. The extracts obtained from winter and summer plants possessed the highest total phenolics. The maximum amount of total flavonoid content was measured in winter (December and January), whereas the minimum one was observed in spring (March). The summer and winter samples showed the highest and lowest content of flavones and flavanols, respectively, whereas the anthocyanin content was higher in winter than in summer. Moreover, antiradical activity of the extracts in summer and winter samples was higher than in other seasons. Overall, this study can provide useful information regarding the best harvest period of Arabian lilac to yield the desired compounds for application in phytopharmaceutical and food industries.
