This study aims to assess the GC-MS and FTIR profiles and secondary metabolites of Ipomoea asarifolia vis-a-vis its antibacterial action against bacteria, associated with wound infections. We conducted phytochemical screenings, GC-MS, and FTIR analyses on I. asarifolia.  The antibacterial effects of the extracts were tested against Staphylococ...

In the study, celery root and celeriac stalk and leaf extracts were prepared using heat-assisted extraction, and the total polyphenol concentration (TPC) and anti-DPPH radical potential of the obtained extracts were determined. The TPC values of the extracts were from 2.67 to 13.43 mg gallic acid equivalent/g, following the trend: ethanol celeriac ...

With the aim to examine the radical scavenging activity of smoke tree extract-loaded liposomal particles before and after ultrasound exposure (45 or 70% amplitude and 15 or 30 min), ABTS and DPPH tests were employed. The antioxidant activity of the pure extract was 11.37±0.52 µmol Trolox equivalent (TE)/mL and 79.7±0.5%. Multila...

Boswellia serrata Roxb. is a tree that is mainly found in the dry regions of India. Its oleoresin, known internationally as Indian frankincense, is used in Ayurvedic, traditional Arabic and Chinese medicine. This gum resin contains 15-20% of boswellic, lupeolic and other pentacyclic triterpenic acids, of which the boswellic acids (beta-boswellic ac...

In this study, the antioxidant, antimicrobial, and cytotoxic activities of Codium bursa, Codium effusum, Laurencia obtusa and Padina pavonica from the Adriatic Sea were investigated. The antioxidant activities were characterized by the DPPH (1,1-diphenyl-2-picrylhydrazyl) method and their total phenolic and flavonoid contents were quantified. The a...

Steppe peony (Paeonia tenuifolia L., Paeoniaceae) is a perennial, herbaceous plant species which has been widely known for its medicinal use. This study is aimed at the development of P. tenuifolia petal dry methanolic extract-loaded liposomes and the determination of their antioxidant activity. The liposomes were prepared with three different phos...

Relatively simple, but very reliable, one-step qualitative/quantitative HPLC analysis of four key flavonoids, and a phenolcarboxylic acid, has been introduced. For substrate/sample preparations, either triple percolations, using 70% ethanol-water (V/V), or/and ultrasonic bath methanol extractions, were carried out to obtain the desired isolates yi...

The microbiological stability of cosmetic products is crucial, especially in products with high water content, such as creams. Therefore, preservatives are used in order to protect consumers from harmful pathogens that would otherwise invade the cosmetics. Despite their function, the addition of preservatives can be considered controversial in the ...

In this study, antimicrobial activity of essential oils extracted from the aerial flowering parts (herbs) of Hyssopus officinalis subsp. aristatus (Godr.) Nyman (Lamiaceae) collected from five different locations in Montenegro, or purchased in Serbia, were investigated. In addition, their antibacterial activity in combination with antibiotics was s...

Paeonia peregrina Mill. and Paeonia tenuifolia L. are endangered species of herbaceous plants with high ornamental and medicinal values. There are a few natural habitats in Serbia where these plants spontaneously grow: Krivi Vir, Skrobnica, Golina, Pirot, Deliblato Sands, and Sokobanja, in the municipality of Knjaževac. In July 2021, the symp...
