Identification by GC-MS of the components of oils of banana peels extract, phytochemical and antimicrobial analyses
Open accessAbstract
Banana is eaten all over the world by all sections of the population.A lectin, called BanLec, was isolated from banana fruit and found to possess anti-HIV-1 activity.However, the peels of banana are thrown away as rubbish although farmers are known to use them as feed for their animals.We thought that there might be some valuable chemicals in banana peels and therefore decided to extract the oils from their peels.Two varieties of Nigeria bananas were chosen for an initial study.The crude methanolic extract was subjected to phytochemical analysis, which revealed the presence of steroids, saponin, terpenoids, anthraquinones and tannins.Antimicrobial study of the methanolic extract showed that the oils were effective against some bacteria.The chemical constituents of the oils were identified and characterized by GC-MS.The fatty acids stearic, palmitic, oleic and linoleic acids and their methyl esters as well as 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-one, 5-(hydroxymethyl)-2-furancarboxyaldehyde, cyclododecane, dibutyl phthalate, b-sitosterol, sesamin and epi-sesamin were among the identified components.These constituents were found to be compounds with known biological and medicinal activity.

Ethanolic extracts of banana peels exhibit antimicrobial properties.
“Ethanolic extracts of banana peels exhibit antimicrobial properties.”
From Potential Valorization of Banana Production Waste in Developing Countries: Bio-Engineering Aspects (2024) · cites this paper as [114]
The Results and Discussion report antimicrobial activity in crude banana-peel extracts against several bacteria. However, the Materials and Methods specify that the peels were extracted and tested using methanol, not ethanol, so the paper does not establish the claim for ethanolic extracts. (LLM, conf=0.90)
Experimental — accuracy not yet measuredMany works have shown different results regarding the chemical compounds in bananas; thus, local research should be carried out to identify unique properties.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
