Antimicrobial and anthelmintic activities of the ethanolic extract, fractions and isolated compounds from Manilkara zapota L. P. Royen (Sapotaceae)

Abstract

Objectives: To evaluate the antibacterial, antifungal and anthelmintic activities of the ethanolic extract (EEMz), fractions (LPFMz and HPFMz) and compounds isolated from the leaves of Manilkara zapota L. P. Royen. Methods: Extract and fractions were produced by turbolization. LPFMz fraction was analysed by gas chromatography-mass spectrometry. The isolated compounds from HPFMz were purified by flash and preparative chromatographic methods, and chemically characterised by UPLC-ESITOFMS, optical rotation, and one-and two-dimensional 1H and 13C NMR techniques. Anthelmintic against Strongyloides venezuelensis and antimicrobial activities against Candida albicans, Trichophyton rubrum and Staphylococcus aureus were evaluated. Key findings: EEMz showed mainly phenolic compounds and pentacyclic triterpenes from Δ12-oleane/Δ12-ursane series. Chlorogenic acid, myricetin-3-O-β-D-glucopyranoside, mearnsitrin, germanicol and germanicol acetate were reported to M. zapota leaves for the first time in this work. EEMz, HPFMz, LPFMz showed significative activity against C. albicans (16 μg/mL), while isolated flavonoids were active against S. aureus (<32 μg/mL). EEMz, phenolic-rich compounds (F2), and chlorogenic acid were potentially active against S. venezuelensis at 24 h. Conclusions: M. zapota and its bioactive compound can be eligible such as a potential phytomedicine for the treatment of microbial and strongyloidiasis drug-resistant infections.
