Tulbaghia violacea Harv. plant extract affects cell wall synthesis in Aspergillus flavus

Aims This study investigates the effect that aqueous extracts of Tulbaghia violacea Harv. harbouring plant saponins, phenolics and tannins have on Aspergillus flavus β‐(1,3) glucan and chitin synthesis. Methods and Results Aspergillus flavus was treated with various subinhibitory concentrations of a...

Zusammenfassung:	Aims This study investigates the effect that aqueous extracts of Tulbaghia violacea Harv. harbouring plant saponins, phenolics and tannins have on Aspergillus flavus β‐(1,3) glucan and chitin synthesis. Methods and Results Aspergillus flavus was treated with various subinhibitory concentrations of an aqueous T. violacea plant extract and the β‐(1,3) glucan and chitin content was determined together with glucan synthase and chitin synthase production respectively. Conclusions The aqueous extract caused a significant decline (P
