Abstract

This study aimed to evaluate the antibacterial activity of ethanolic extracts obtained from the leaves of Aglaonema commutatum Schott and its cultivars («Malay Beauty», «Silver Queen», and «Silver King») against Escherichia coli (Migula) Castellani and Chalmers (ATCC® 25922™) strain. The leaves of Aglaonema commutatum plants and its cultivars, cultivated under glasshouse conditions, were sampled at M. M. Gryshko National Botanic Garden (NBG), National Academy of Science of Ukraine (Kyiv, Ukraine). The leaves were brought into the laboratory for antimicrobial studies. Freshly sampled leaves were washed, weighed, and homogenized in 96% ethanol (in proportion 1:19) at room temperature. The extracts were then filtered and investigated for their antimicrobial activity. Escherichia coli (Migula) Castellani and Chalmers (ATCC® 25922™) strain was used in our study. Antimicrobial activities of various ethanolic extracts obtained from leaves of Aglaonema commutatum plants and its cultivars («Malay Beauty», «Silver Queen», and «Silver King») against Escherichia coli (Migula) Castellani and Chalmers (ATCC® 25922™) strain was screened in the current study. The testing of the antibacterial activity of the plant extracts was carried out in vitro by the Kirby-Bauer disc diffusion technique. The leaf extracts from A. commutatum «Silver Queen» and A. commutatum 'Silver King' exhibited higher inhibitory activity than the extracts from A. commutatum and A. commutatum «Malay Beauty». Maximum in vitro inhibition was scored by A. commutatum «Silver Queen», followed by A. commutatum «Silver King», A. commutatum, and A. commutatum «Malay Beauty». In particular, the leaf extracts from A. commutatum «Silver Queen» and A. commutatum 'Silver King' exhibited higher inhibitory activity than the extracts from A. commutatum and A. commutatum «Malay Beauty». Maximum in vitro inhibition was scored by A. commutatum «Silver Queen», followed by A. commutatum «Silver King», A. commutatum, and A. commutatum «Malay Beauty», which presented inhibition zones of (18.6±1.2) mm, (16.1±0.9) mm, (15.7±1.1) mm, and (13.5±1.0) mm, respectively. In the case of the positive controls, 96% ethanol possesses a mild anti-E. coli effect, which presented inhibition zones of (9.5±1.2) mm. The inhibition zone diameters were increased by 96% (p<0.05) for A. commutatum «Silver Queen», by 69 % (p<0.05) for A. commutatum «Silver King», by 65 % (p<0.05) for A. commutatum, and by 42 % (p<0.05) for A. commutatum «Malay Beauty». Thus, the use of these plants in traditional medicine and veterinary medicine was experimentally confirmed as a potential source of raw materials for the development of medicines in the future, as well as for the development of innovative feed for farm animals.
