ABSTRACT:

The global burden of infectious illnesses and drug abuse necessitates the rapid discovery of novel medications derived from medicinal plants. The study’s goal was to analyze the antibacterial activity of ethno-medicinal plants. In the research region, medicinal plants Cassia fistula Linn. (Amaltas), Delonix regia (Hook.) Raf. (Gulmohar), and Albizia lebbeck (L.) Benth. (Siris) have been utilized to cure a range of ailments. According to this investigation, hexane and acetone extracts of all three plants had the highest MIC value against Sclerotinia sclerotiorum. All three plants’ ethanolic extracts have a considerable MIC against Aspergillus niger. Ethanolic extracts of Delonix regia (Hook.) Raf. (Gulmohar) and Albizia lebbeck (L.) Benth. (Siris) also have a large MIC against Pseudomonas syringae; however, acetone extracts of Cassia fistula Linn. (Amaltas) have an effective MIC against Pseudomonas syringae. Results against Erwinia carotovora are encouraging for the ethanolic extract of Delonix regia (Hook.) Raf. (Gulmohar), the acetone extract of Albizia lebbeck (L.) Benth. (Siris), and the ethanolic and acetone extracts of Cassia fistula Linn. (Amaltas). The outcome presented suggests prospective sources for the medicinal plants under investigation as antimicrobial agents; hence, more in vitro and in vivo antimicrobial activity investigations are advised.
