研究目的
Investigating the therapeutic effects of flavonoid extracts from Aframomum alboviolaceum on water disinfection through photosensitization.
研究成果
The flavonoid extracts from Aframomum alboviolaceum roots demonstrated significant photosensitizing activity, leading to the complete inhibition of fecal coliforms in water after one hour of sunlight exposure. This suggests a potential application in water disinfection, especially in areas lacking access to conventional treatment methods.
研究不足
The study did not investigate the fixation of these products on a solid support such as a polymer or glass, nor the sensitivity of parasites and viruses to these products.
1：Experimental Design and Method Selection:
The study involved the extraction of flavonoid compounds from Aframomum alboviolaceum roots using ethyl acetate, followed by separation and characterization through chromatography and UV spectroscopy.
2：Sample Selection and Data Sources:
Water samples contaminated with fecal coliforms were collected from the University of Kinshasa.
3：List of Experimental Equipment and Materials:
Methanol, ethyl acetate, ether, chloroform, silica gel, UV spectrophotometer.
4：Experimental Procedures and Operational Workflow:
The extracted flavonoids were tested for their photosensitizing activity by exposing treated water samples to sunlight and comparing with samples kept in the dark.
5：Data Analysis Methods:
The inhibition of fecal coliforms was measured over time to assess the effectiveness of the photosensitization process.
