UPLC-QTOF-MS/MS and Antifungal Activity of a Fraction Enriched in Saponins From Sarcomphalus joazeiro Against Candida spp. [PDF]
Biomed ChromatogrABSTRACT The development of antifungal resistance is a complex process that involves the interaction between hosts, drugs, and microbial factors, all of which contribute to therapeutic ineffectiveness. For this reason, studies on natural products as possible therapeutic alternatives are increasingly necessary in order to gain a better understanding of ...
