Item The GC–MS analysis of the diethylether and ethylacetate fraction of the peel of Solanum incanum and the study of their antibacterial activity(Institute of Korean Medicine, Kyung Hee University, 2022) Ravichandran,YetayihThe diethyl ether and ethyl acetate fractions of the peel of the fruit of Solanum incanum. (S. incanum) were analyzed using gas chromatography-mass spectrometry (GC–MS). 105 compounds were identified in the diethyl ether fraction and 75 compounds were identified in ethyl acetate fraction. Among them, 5 compounds were analyzed by fragmentation pattern,discussed, and compared with NIST database. The antibacterial screening was also conducted for bothdiethyl ether and ethylacetate fractions of the fruit peel of S.incanum using four pathogens, two Gram-positive bacteria Staphylococcus aureus(S. aureus) and Streptococcus pyogenes (S. pyogenes) and two Gram negative bacteria Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumonia), at various concentrations (250, 500, 750 and 1000 μg/ml). The diethyl ether and ethyl acetate fractions of the peel of S. incanum exhibited activity against E. coli and K. pneumonia at 1000 μg/ml concentration.
