“…Tannins may have contributed in part to the antimicrobial activities of the extracts against E. coli, Salmonella spp and Shigella spp. as noted in previous studies (Bamisaye et al, 2013;Chingwaru et al, 2020). Several compounds such as swartziadione, isolated from the root, showed good antimicrobial activity against Aspergillus and Staphylococcus (Hostettmann & Schaller, 1999).…”

“…The extraction of secondary metabolites can be done using cold or hot extraction method. Many researchers have been used cold or hot extraction method for successful expression of secondary metabolites (Yehiaetal,2020;Grigolettoetal,2019;Boghsanietal., 2020;Chingwaru et al, 2020). Dileep et al, (2013) have been used aqueous extract of leaf and pericarp of Polyalthia (gc-gt)/gc×100 longifolia to control Fusarium oxysporum fungus in zingiber crop and Pythium aphanidermatum.…”

Phytochemicals are chemical compounds which are also called as a secondary metabolite. Different types of secondary metabolites synthesized by plants which are play important role in biotechnological application and also in antimicrobial activity. In the present study were carried out to determine in vitro the antifungal activity of alcoholic, hydroalcoholic and aqueous crude extracts of Polyalthia longifolia leaf against Rhizoctonia solani fungus. All these extracts i.e., 100% aqueous, 100% alcohol and 50% hydro alcohol used as 10mg/ml concentration with acetone solvent to control of Rhizoctonia solani. The results revealed that the extract that most effectively inhibited growth was found to be 100% alcoholic leaf extract. Finding in this study confirmed that plant extracts can be used as to develop the plant extract-based bio-formulation to control plant pathogens to reduce the dependence on the synthetic fungicides which are ecological safe and cheap.

In this study antifungal activity of crude and partially purified extracts of Lawsonia inermis Leaf extract has been assayed against Alternaria alternata which is responsible for leaf spot disease of chilli. Cold and hot extraction of leaf extract was prepared in different organic solvents, which were subsequently recycled by rotary vacuum evaporator. Antifungal activity of prepared plant extracts were determined by poison food technique. In cold extraction highestpercent extractive value was obtained with 50% alcohol extract and in hot extraction highest percent extractive value was obtained with Methanol extract. In antifungal activity 100% alcohol crude extract and partial purified acetone extract was show Maximum inhibition of Alternaria alternata. Mancozeb and water were used as standards. Results suggest that Lawsonia inermis. Leaf extract can be used to develop a bio control agent against Alternaria alternata. Lawsonia inermis plant can be used to discover bioactive natural products that may serve as leads in the development of new pharmaceuticals research activities.
