abstract = "Within the project of bilateral cooperation between Montenegro and Serbia, a project
called ‘Biocontrol of phytopathogenic fungus by natural products from subtropical
plants order Rosales’ is being implemented. Natural plant extracts are an alternative
to synthetic fungicides or as an additional way to reduce their use. The choice and
application of plant extracts depends on their functional characteristics, availability,
cost-effectiveness and their impact on phyto-pathogens.
The project is focused on researching the biological properties of extracts of two
subtropical plants from Montenegro: Celtis australis and Ziziphus jujuba, that previously
were not recognised for this purpose.
Four extracts of Z. jujuba obtained from dried fruits (using various solvents: methanol,
water, dichloromethane and n-butanol), and methanolic extracts prepared from leaves
and unripe mesocarps of C. australis, were evaluated for their phenolic compounds
composition as well as antimicrobial and cytotoxic properties. Both species extracts
were rich in phenolic compounds.
Results showed that all of Z. jujuba extracts possess antibacterial/antifungal activity
against seven tested bacterial species (belonging to human infectious agents and
food contaminants) and fungi (four clinical isolates of dermatomycetes and six
phytopathogens). The extracts showed very high antimicrobial potential, slightly weaker
in the aqueous extract. No difference in antifungal potential according to the origin of
the extracts was shown.
Extracts of Celtis australis contain various bioactive constituents and possess higher
antifungal potential than ‘Previcur’, which is a commercial systemic fungicide used in
controling production of vegetable seedling.
Therefore, both species extracts represent potential, Z. jujuba as source of new
compounds with antimicrobial activity, while extracts of Celtis australiscan has a potential
for application in agriculture as an alternative to the syntethic fungicides.
Worth mentioning is that the examined extracts are natural biodegradable fungicides
which enable a more efficient control of pathogenic bacteria and fungi.",
