This study investigated the antimicrobial activity and chemical composition of Annona muricata leaf oleoresin extracted by supercritical CO2. The oleoresin showed high bactericidal activity against various bacteria, but low fungicidal activity. Promising applications in food, cosmetic, and pharmaceutical industries were suggested for the leaf oleoresin of A. muricata.
Bioactive compounds extracted from plants such as antimicrobials have attracted the attention of consumers and the food industry. This study aimed to determine the antimicrobial activity and chemical composition of Annona muricata leaf oleoresin obtained by supercritical CO2 extraction. The oleoresin was obtained by supercritical CO2 extraction and the chemical identification by gas chromatography coupled to mass spectrometry. Antimicrobial activity was evaluated by broth microdilution method against 14 foodborne fungi and bacteria. The oleoresin major chemical class was phytosterols (22.7%) and the major compounds were gamma-sitosterol (15.7%), alpha-tocopherol (13.7%), phytol (13.1%), and hexadecanoic acid (11.5%). Minimum inhibitory concentration against bacteria ranged from 0.0025 to 0.010 mg mL(-1). The oleoresin had high bactericidal activity against all bacteria, mainly Enterobacter cloacae and Pseudomonas aeruginosa with 0.005 mg mL(-1) minimum bactericidal concentration. However, it had low fungicidal activity. The leaf oleoresin of A. muricata has promising applications in food, cosmetic, and pharmaceutical industries.
