Invasive Plants: Turning Enemies into Value

Area of Science:

• Ecology
• Phytochemistry
• Pharmacology

Background:

• Invasive plant species disrupt ecosystems and pose significant environmental challenges.
• Understanding the secondary metabolites and biological activities of invasive plants is crucial.

Purpose of the Study:

• To review the ecological impact of invasive plants.
• To explore the chemical and pharmaceutical potential of five invasive plant species threatening Portugal.
• To highlight the positive attributes of invasive species for potential applications.

Main Methods:

• Literature review of invasive plant phenomena and their ecological consequences.
• Selection and description of five invasive plant species prevalent in Portugal.
• Detailed analysis of secondary metabolites and biological activities of selected species.
• Resume of the biological activity of plant extracts.

Main Results:

• Invasive plants have detrimental effects on native ecosystems.
• The selected invasive species possess diverse secondary metabolites.
• Extracts from these invasive plants exhibit various biological activities.
• Significant chemical and pharmaceutical potential was identified in invasive species.

Conclusions:

• Invasive plant species, despite their negative ecological impact, possess valuable chemical and pharmaceutical properties.
• Developing applications from these properties could provide economic benefits and aid in managing invasive species.
• This study acknowledges the dual nature of invasive species, presenting both challenges and opportunities.
