Biomass production and antibacterial activity of Justicia gendarussa Burm. f. - A valuable Medicinal plant

Abstract

Rooting and biomass production of Justicia gendarussa has been achieved through a hydroponic system of cultivation. The obtained biomass of leaves, stem and root were examined for antibacterial activity against various human pathogenic organisms such as Staphylococcus aureus, Escherichia coli, Shigella sp., Pseudomonas sp. and Klebsiella pneumoniae. Methanolic extract of J. gendarussa root responded against E. coli. The growth of Shigella sp., Pseudomonas sp. and K. pneumonia were inhibited by leaf extract. The maximum inhibition zone against S. aureus was observed in stem extract treatment.

Overview of the Justicia Genus: Insights into Its Chemical Diversity and Biological Potential

“…Justicia species are used in folk medicine for the treatment of numerous pathologies, such as depression, anemia, epilepsy, kidney infection, respiratory problems, gastrointestinal diseases, arthritis and fever [ 8 ]. Other biological activities have been determined from the plant extracts of Justicia , such as antioxidant [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], antimutagenic [ 18 , 19 ], anticancer [ 22 , 23 , 24 , 25 ], anti-HIV [ 26 , 27 , 28 , 29 , 30 , 31 ], antimicrobial [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ], antidiabetic [ 43 , 44 , 45 ], among others. It is worth mentioning that there is currently relevant interest among research groups in evaluating a possible analgesic, anti-inflammatory and antiulcerogenic activity.…”

“…It is worth mentioning that there is currently relevant interest among research groups in evaluating a possible analgesic, anti-inflammatory and antiulcerogenic activity. A diversity of special metabolites is found in Justicia , mainly alkaloids [ 46 , 47 , 48 , 49 , 50 , 51 ], steroids [ 52 , 53 , 54 ], tannins [ 32 , 41 , 46 , 51 ], terpenoids [ 47 , 48 , 51 , 54 , 55 , 56 , 57 , 58 ], lignans [ 59 , 60 , 61 , 62 , 63 , 64 ] and flavonoids [ 16 , 20 , 21 , 22 , 23 , 24 , 31 , 32 , 51 , 65 , 66 , 67 ].…”

Antimicrobial, Antifungal and HRBC Membrane Hemolysis and Membrane Stabilization Properties of Various Extracts of Justicia gendarussa

“…These antibacterial results collaborate with previous findings. 16 The plant extracts of the J. gendarussa caused the inhibition of Aspergillus niger, Fusarium, Nigrospora oryza, and Aspergillus flavus. The ethanol extract showed the highest inhibition as compared to water and petroleum ether extracts.…”

Hydrothermal liquefaction for biochar production from finger millet waste: its valorisation, process optimization, and characterization

“…With the abundance and accessibility of agricultural byproducts, they prove to be ideal raw materials for biochar manufacturing and waste management, as highlighted by Sugumaran and Seshadri. 12 Every year, the production of waste biomass reaches a staggering 220 billion dry tonnes worldwide, making it the most signicant and environmentally friendly source of biomass. 13 As the global demand for nutritious and sustainable crop options continues to rise due to increasing hunger, food insecurity, and challenges in our food systems, millets have become a top choice.…”
