“…However, that other non-polyphenolic TVV compounds contribute to its actual fungistatic activity cannot be excluded. For example ubiquitous plant lipids have been reported to exert some antifungal activity [52]. To this purpose, since the lipid fraction of TVV has not been characterized here, it will be specifically and comparatively investigated in a future study.…”

The in vitro antifungal activity was determined of an ethanolic extract of Vitis vinifera L. tendrils (TVV) against ten plant pathogenic fungi, using the agar dilution method; activity was shown against all tested fungi. Fusarium species were the most sensitive with MIC values ranging from 250 to 300 ppm, while the basidiomycete fungus Rhizoctonia solani was the most resistant, with a MIC value of 500 ppm. Electrospray ionization tandem mass spectrometry (ESI-MS n) was used to obtain qualitative information on the main components of TVV. The high amount of polyphenolic compounds contained in TVV is likely to contribute significantly to its antifungal activity.

“…In addition, preliminary phytochemical screening of Thymus capitatus revealed the presence of saponins, resins, flavonoids, essential and fixed oils; compounds of profound inhibitory effect against several bacteria and fungi (Kandil et al, 1994). In addition, Tabti et al (2015) identified fifteen fatty acids accounting for 95% of the lipid content responsible for the in vitro antifungal activity of this species. The potency of the antifungal activity of plant extracts was estimated in terms of the relative inhibition of fungal growth below the control.…”

Fungi are the major disease-causing agents of fruits. They cause considerable losses to post harvest fruits during transportation and storage. Ten infected fruit species were collected from the local markets in Damietta Governorate, Egypt for surveying the fungal pathogens on these fruits. Ten fungal species were isolated and identified, among them, Alternaria alternata and Fusarium oxysporum exhibited the most prevalent fungal species isolated from mandarins and grapes, respectively. In this study, the aqueous and ethanolic extracts of eleven wild medicinal plants were tested against the two prevalent fungi at five concentrations (0, 1, 3, 5, 10%; w/v). The greater relative inhibition of fungal growth, along with the lower C50 values revealed that the ethanolic extract of the tested plants exhibited the stronger antifungal activity when compared to water extracts. Out of the eleven plant species investigated, Thymus capitatus and Eucalyptus citriodora were the most effective for fungal growth, while Nicotiana glauca was the least effective. Therefore, we recommend the using of Thymus capitatus and Eucalyptus citriodora extracts as potential antifungal preservatives for fruits against fungal spoilage.

“…As for the lipid composition, the hexane extract of Algerian T. capitatus was shown to contain α-linolenic (29.6%), palmitic (16.6%), linoleic (15.1%) and behenic acid (9.6%) [ 15 ]. In 2019, Zaïri and colleagues described the fatty acid content in essential oil from a Tunisian plant of the same species.…”

Chemical and Biological Profile and Allergenicity of Thymus baicalensis Plant of Mongolian Origin

Thymus baicalensis is a medicinal plant recognized as a traditional Mongolian therapeutic and health-promoting food supplement. The aim of the study was to check the suitability of the tested plant for supporting the treatment of certain diseases. The following study is the first one to showcase the versatile scope of characteristics of T. baicalensis, including its volatile oil composition, polyphenolic composition, lipid composition, phenolic and flavonoid contents, antioxidant activity, antimicrobial properties and ingestive allergenicity. Myrcene, at 26.15%, was shown to be the most abundant component of the volatile oil. Compounds known as inherent components of the Thymus genus: thymol and carvacrol made up only about 0.24% of the extracted oil. As much as 10.11 g kg−1 of polyphenol compounds were identified as derivatives of luteolin-7-O-glucuronide. The lipid extract was found to be rich in palmitic acid (31.05%), while unsaturated fatty acids were not reported. Spectrophotometric determination of the phenols and flavonoids indicated 7.541 mg of gallic acid g−1 and 4.345 mg of quercitin g−1, respectively. The free radical scavenging activity was determined by the 2,2-difenylo-1-pikrylohydrazyl method at IC50 = 206.97 µg mL−1. The extracts also had a strong inhibitory effect on M. flavus and P. fluorescenes bacteria, as well as S. cerevisiae yeasts. The Bet v 1 and profilin allergens in T. baicalensis were reported at 175.17 ng g−1 and 1.66 ng g−1, respectively.
