The study investigates the impact of drying Alpinia leaves on the properties of their essential oils, utilizing mathematical models to analyze the drying process. Results indicate significant variations in essential oil characteristics based on drying conditions, with 45 °C yielding optimal antimicrobial activity and lower toxicity. The findings highlight the importance of drying temperature in affecting the physicochemical and biological properties of essential oils, underscoring the need for further research to refine predictive models for drying processes.

The study focuses on the impact of drying Alpinia zerumbet leaves on the properties of their essential oils (EOs), utilizing mathematical models to analyze drying kinetics. Results indicated that drying at 45 °C yielded the most effective EOs, showcasing superior antimicrobial activity and low toxicity. The findings highlight the significance of drying temperature in affecting the physicochemical and biological characteristics of EOs, emphasizing the need for further research on optimal drying conditions and their influence on essential oil quality.

The study investigates the chemical profiles and antimicrobial properties of essential oils from C. citratus, O. basilicum, and A. rosaeodora. Utilizing hydrodistillation and gas chromatography-mass spectrometry, the research identifies key components such as linalool in A. rosaeodora and geranial in C. citratus. Antimicrobial tests reveal varying inhibition zones, with O. basilicum showing the strongest effect against S. aureus. The findings highlight the potential of these essential oils in controlling pathogenic microorganisms, supporting their application in health and safety contexts.
