The genus Onosma L. (Boraginaceae) is represented in Turkey by 105 species (110 taxa), 53 of them and 1 variety are endemic for Turkey. Some species of Onosma are used as herbs, traditional medicine such as against burns, wounds and ailments. Hydrodistilled essential oils of the aerial parts of Onosma isaurica Boiss. & Heldr. and Onosma bulbotrichum DC. were analyzed by GC and GC-MS systems, simultaneously. The essential oil of O. isaurica contained hexahydrofarnesyl acetone (20.3%), phytol (19.0%), farnesyl acetone (8.1%) and neophytadiene isomer I/tetradecanal (7.0%) as main constituents. The oil of O. bulbotrichum was characterized by the occurrence of hexahydrofarnesyl acetone (11.6%), farnesyl acetone (9.9%), hexadecanal (8.8%) E-geranyl acetone (7.4%) and neophytadiene isomer I (7.3%) as major components.

“…MeOH-assisted extraction produced the highest yield for C2 (42.18%) while IVLS produced the least yield (17.36%) (Table 4). MeOH was chosen on the basis that it extracts bioactive components including phenolics, flavonoids, alkaloids, and terpenoids besides being reported to increase the extraction yield for Onosma sieheana (6.5%) (Binzet et al, 2019),…”

Plant cells are driven by types and concentrations of plant growth regulators to produce callus mass containing bioactive compounds. This study aimed to induce callus and to observe the histological, phytochemicals, and antioxidant basis of the callus. An efficient callus induction protocol was developed using picloram for Malaysian red ginger, Zingiber officinale var. rubrum. The effect of auxinic picloram herbicide was studied using six different concentrations (0, 0.5, 1, 2, 4, and 8 mg/L) on various explants (leaf sheath, leaf, root) to optimise the callus induction. The induced callus was studied for growth kinetics, anatomical features, antioxidant capacity, and phytochemical content. The highest callogenesis frequency (93.75%) and biomass accumulation (3.68 g) were observed on leaf sheath explant cultured on ½ strength Murashige and Skoog (MS) medium supplemented with 8 mg/L which also requires earlier subculture duration (45 days post-inoculation) in comparison to lower concentrations. Morphological investigation through histological procedure demonstrated friable and non-embryogenic characteristics of the primary and subcultured callus. Cultivated leaf sheath (CLS) methanolic extract showed the highest total phenolic (191.26 mg GAE/g dry extract) and flavonoid (4.54 mg QE/g dry extract) contents contributing to antioxidant activity with an estimated EC50 of 0.208 mg/mL. Although comparatively lower than CLS extract, callus extracts showed higher antioxidant activity and significantly lower EC50 values than in vitro leaf sheath extract. 4H-Pyran-4-one, 2,3-dihydro-3,5-dihydroxy-6-methyl-, phenol, and phenolic glucoside were only present in callus cultures while methyl esters, fatty acids, and phytosterols could be obtained from leaf sheath and callus extracts. In conclusion, the callus culture of Z. officinale var. rubrum is a potential renewable source of bioactive phytochemical compounds and can be employed for biotechnological practices such as elicitor-induced accumulation of secondary metabolites and genetic modification.

“…The essential oils isolated from roots of O. sieheana showed appreciable antibacterial activity against gram negative bacteria (Escherichia coli (MIC: 125 µg/mL) and Pseudomonas aeruginosa (MIC: 125 µg/mL) and gram positive bacteria (Staphylococcus aureus (MIC: 125 µg/mL) and Bacillus subtilis (MIC: 250 µg/mL)) [78]. The n-hexane-dichloromethane mixture extracts of O. argentatum roots showed antibacterial activity against Bacillus sub-tilis, Escherichia coli, and Staphylococcus aureus with MIC values 28, 13, and 32 µg/mL, respectively [18].…”

Ethnobotanical, Phytochemistry, and Pharmacological Activity of Onosma (Boraginaceae): An Updated Review

et al. 2022

View full text Add to dashboard Cite

The genus Onosma belongs to the Boraginaceae family and contains over 230 species. The present review sheds light on the ethnopharmacology, phytoconstituents, bioactivity, and toxicology of the Onosma species from previous investigations. Furthermore, the paper also highlights the unresolved issues for the future investigations. The review included previous studies of the genus Onosma available from Google Scholar and Baidu Scholar, Science Direct, SciFinder, Wiley Online Library, and Web of Science. Until now, more than 200 chemical compounds have been detected from the genus Onosma, including naphthoquinone (33), flavonoids (30), hydrocarbon (23), phenolic (22), ester (17), alkaloids (20), aromatics (12), carboxylic acid (11), fatty acids (9), terpenoids (10), while the most important ones are rosmarinic, ferulic, protocatechuic, chlorogenic, caffeic, p-coumaric acids, and apigenin. The Onosma species are reported as traditional medicine for wound healing, heart disease, and kidney disorders, while the pharmacological investigations revealed that the extracts and the phytochemicals of Onosma species have different therapeutic properties including antioxidant, enzyme inhibitory, antitumor, hepatoprotective, antiviral, anti-inflammatory, and antimicrobial actions. The summarized knowledge in this review provides valuable ideas for the current and future drug discovery and a motivation for further investigation on the genus Onosma.
