“…In these studies, inhibition of the activity of selected bacterial taxa was demonstrated, and the results became the basis for further research on anti-bacterial activity. In recent years, ginkgetin [ 129 , 133 ], amentofavone [ 132 ], ginkgolic acid C15:1 monomer [ 134 ] and polyprenol [ 135 ] and the effectiveness of leaf extracts obtained with the use of various solvents (water, ethanol, chloroform and methanol) [ 136 , 137 , 138 , 139 ]. The group of microorganisms has been significantly expanded, including taxa of gram-positive and gram-negative bacteria [ 125 , 126 , 134 , 136 , 138 , 140 , 141 ], intestinal microflora typical of the tested mammalian organisms [ 137 , 139 ], as well as human pathogenic fungi (e.g., Candida albicans used in the study by) [ 141 ].…”
