“…Paulownia is one of the traditional Chinese medical ( 13 ), which contains a variety of active ingredients such as flavonoids, phenolic acids, saponins, phenylethanoid glycosides, lignans, and triterpenoids in its leaf, fruit, and flower ( 12 , 19 , 35 ), with multiple pharmacological and economical values ( 18 ). Our GC mass analysis demonstrated that the methanolic extract of P. tomentosa included large amounts of thymol, phytol, flavonoids, and other bioactive compounds, which indicates the great efficacy of methanol as an organic solvent in extracting the primary bioactive molecules found within leaves.…”

“…Paulownia ( P. tomentosa ) is one of the most exploited medicinal plants that grow natively in China, Japan and the Far East Asian countries ( 12 , 13 ). Besides, it has been used in traditional Chinese medicine to treat or prevent a wide range of infectious diseases ( 14 ).…”

“…In UV light (before derivatization), signals in the form of orange bands from chlorophylls were also visible, with Rf = 0.85 and 0.91), especially intense in the case of OX 3 and 4C S9 II clones. An interesting combination of HPTLC techniques with the analysis of antibacterial properties (bioautography) was applied to the studies of methanolic leaf extracts of P. tomentosa by Moricz et al [49]. They showed the presence of compounds such as p-coumaric acid and apigenin and their strong activity against Bacillus subtilis and Aliivibrio fischerii bacteria.…”

“…We can observe that clones with the lowest verbascoside content ('OX3' and' COT1') have the weakest antibacterial properties, while those with the highest verbascoside content show the strongest antibacterial properties. The possible mechanism of antibacterial action of verbascoside is correlated with its capability to modulate membrane-dependent cellular processes [49].…”
