Antifungal activity from polar and non-polar extracts of some Chenopodiaceae wild species growing in Tunisia

Abstract

Nine plants belonging to Chenopodiaceae family were collected around salt marshes near Monastir, located in the east Mediterranean coast of Tunisia. They were tested for their antifungal activities against six plant pathogenic fungi: Botrytis cinerea, Fusarium oxysporum f. sp. niveum, F. solani f. sp. cucurbitae, Phytophthora cactorum, Rhizoctonia solani and Nattrassia mangiferae. Data of this study showed that the highest inhibition of Botrytis cinerea growth was observed with the petroleum ether extract of Atriplex inflata fruits (F) (24.5 mm). The in vitro growth of F. oxysporum f. sp. niveum was reduced only with A. inflata whole plant (WP) petroleum ether extract (32.3 mm). The most important inhibition zones were obtained against F. solani f. sp. cucurbitae with Atriplex semibaccata methanol and acetone extracts (34.7 and 31.0 mm, respectively). This work revealed that fungitoxic compounds were probably present in the petroleum ether extract obtained from A. portulacoides (WP), since it has suppressed the growth of F. s. cucurbitae. Our investigation proved that many Chenopodiaceae species adapted to saline soils may contain phytochemical compounds with fungicidal properties.

Halophytic herbs of the Mediterranean basin: An alternative approach to health

“…Also known as Mediterranean saltbush, Atriplex halimus L. is a euhalophyte native in the broad Mediterranean region usually used as a fodder or for medicinal purposes (Walker et al, 2014). According to Boughalleb et al (2009) and Bendaly et al (2016), low to moderate salinity had a stimulating effect on plant growth mainly due to promoting root and stem growth, while the salt tolerance could be attributed to compartmentalization of high amounts of Na + , the 2016a Total phenolic content is expressed as gallic acid (GAE) equivalents (mg gallic acid g −1 dry weight (DW)). b Total phenolic compounds as determined by LC-DAD-ESI/MS.…”

Bioactivities and Health Benefits of Wild Fruits

“…In addition, several water and methanol extracts of the 16 cultivars selected from Taiwanese indigenous wild bitter gourd ( Momordica charantia ) showed inhibitory activity against the growth of E. coli and Salmonella enterica [116]. Results of another study revealed that a petroleum ether extract of wild Atriplex inflata fruits possessed high inhibitory activity against Botrytis cinerea [117]. …”

Protective effect of Atriplex�suberecta extract against oxidative and apoptotic hepatotoxicty

“…Recently, triterpenoids isolated from A. laciniata demonstrated antibacterial, antioxidant and antiurease activities ( 15 ), including anticholinesterase effects against Alzheimer's and other neurological disorders ( 16 ). The fungicidal effects of A. semibaccata, A. portulacoides and A. infalata have been previously reported ( 17 ) and the molluscicidal and larvicidal activities of A. inflata have also been identified ( 18 ). Furthermore, Gođevac et al ( 19 ) revealed that flavonoid glycosides isolated from the aerial parts of A. littoralis exhibited protection against in vitro biochemical and cytogenetic damage to human lymphocytes ( 19 ).…”
