Objective: The aim of this study was to
screen various extracts of plant of Gentian (Gentiana pyrenaica L.),
Tarragon (Artemisia dracunculus
L.), Persimmon (Diospyros kaki), Raspberry (Rubus ideaus) to display potent
antimikrobial, antifungal and antioxidant activity in vitro, total phenolic
and flavonoid contents in order to find possible sources for future novel
antioxidants in food and pharmaceutical formulations.
Material and Methods: The antioxidant properties of 12 different samples of
medicinal and aromatic plants such as leaves, flowers and scapus were
investigated by DPPH, FRAP and CUPRAC assays. Total phenolic, total
flavonoid content and the antimicrobial properties of extracts from these
plants were also determined. Antibacterial and antifungal activities were
investigated by microdilution method and agar diffusion method respectively.
Results: According
to the determination of antioxidant results, dried leaves of Persimmon
(Diospyros kaki) (obtained from
Trabzon) plant had the best antioxidant
activity that was carried out in all analyzes (except the analysis of total
polyphenol). In accordance with analysis of total
polyphenol, activity of purple flower of Gentian (Gentiana pyrenaica L.)
plant was measured at
31,303±0,274 mg GAE /g dry sample and thus this plant had the highest total phenolic
content. Antimicrobial activity tests were carried out using disc diffusion
methods with 12 microbial species and most of them displayed good-moderate
antimicrobial activity.
Conclusion: Due to their antimicrobial, antifungal and
antioxidant properties, the extracts some of these plants might be used as
potential sources of natural
antioxidant and antimicrobial agents.
