Summary
This study investigated plant extracts for antimicrobial properties. Psidium guajaba and Costus spicatus showed promising antimicrobial activity in specific extracts.
Area of Science:
- Phytochemistry
- Microbiology
- Pharmacognosy
Context:
- Antimicrobial resistance is a growing global health concern.
- Natural products offer a potential source for novel antimicrobial agents.
- Plant-derived compounds are increasingly explored for therapeutic applications.
Purpose:
- To evaluate the antimicrobial potential of various plant extracts.
- To identify specific plant parts and extraction methods yielding significant activity.
- To screen plants from Myrtaceae, Polypodiaceae, and Zingiberaceae families.
Summary:
- Aqueous, alcoholic, and ketonic extracts from five plant species were tested.
- Psidium guajaba leaf and stem ketonic extracts demonstrated notable antimicrobial effects.
- Costus spicatus leaf and root alcoholic extracts also exhibited significant antimicrobial activity.
Impact:
- Highlights effective plant-derived antimicrobials for further research.
- Provides a basis for developing new antimicrobial therapies from natural sources.
- Contributes to the understanding of ethnobotanical uses of selected plants.
