Chemical Composition and Antioxidant Activities of Tunisian Thymus capitatus L. Methanolic Extract

Abstract

Thymus capitatus has traditionally been considered as an anthelmintic, antispasmodic, carminative, emmenagogue, expectorant, rubefactient, sedative, stimulant, and tonic. This work was carried out to determine total polyphenol and total flavonoids, chemical composition of phenolics and to evaluate the antioxidant activities of the methanolic extract. Total phenolic contents were assayed using the Folin-Ciocalteu reagent, total flavonoid content was measured

Phenolic compounds’ characterization of Artemisia rutifolia spreng from Pakistani flora and their relationships with antioxidant and antimicrobial attributes

“…They are extensively studied for their antioxidant, anticarcinogenic, and antimicrobial attributes. [23] We evaluated, in this study, the total phenolic and total flavonoid contents of A. rutifolia leaf extracts. The results are shown in Fig.…”

Phytochemical Composition, Antioxidant and Antifungal Activity of Thymus capitatus, a Medicinal Plant Collected from Northern Morocco

“…The TPC in our TcLME (73 mg GAE/g of DE = 8.18 mg GAE/g of DW) was significantly lower than the ones from the different bioclimatic zone (sub-humid, upper semi-arid, means semi-arid, lower semi-arid, upper arid and lower arid) in Tunisia with the values were ranged from 12.6 to 42.7 mg GAE/g of DW [60]. Using aerial parts of T. capitatus, Msaada et al [46] were found a lower amount of TPC in methanolic extract in four Tunisian regions, namely Kef, Grombelia, Bizerte, and Boukornine, with the values of 18. 40 To our knowledge, there has been no investigation on phenols contents of acetonic extract of T. capitatus, whereas TPC of EO was only reported in Morocco by Ouadan et al [61] using a mix of leaves and flowers, and the value (4.74 mg GAE/mL of EO) was close to the amount given in our TcLEO (5.18 mg GAE/mL of EO).…”

“…Nowadays, EOs and their components are gaining increasing interest because of their relatively safe status and exploitation for potential multi-purpose functional uses [37]; they can be (nano) encapsulated with zein to increase the shelf life of food by inhibiting fungus [38]. T. capitatus possess different biological effects such as antioxidant, antifungal, antibacterial, and antiviral [39][40][41][42][43][44][45][46].…”

Antibacterial effects of Thymus algeriensis extracts on some pathogenic bacteria

“…The phenolic content of plant extract depends on various parameters such as genetic and ecological factors, the part of the plant used, the extraction method employed and even plant age (Amarti et al 2010;Gharibi, Tabatabaei, & Saeidi, 2015). Msaada et al (2016), have revealed that both total phenols and flavonoids varied significantly among the region of collection, probably due to the dissimilarities in the soil, climate, solar lighting, humidity, and temperature, which could be affecting samples in each studied region.…”
