Medicinal plants accumulate heavy metals from contaminated soil, and their consumption can cause poisoning. Our objective was to determine the levels of Pb, Cd, Zn, Cu, Fe, Mn in four medicinal plant species (Achillea millefolium, Hypericum perforatum, Plantago lanceolata, Urtica dioica) native all sampled at a former smelter. The highest soil Zn surpassed maximum allowed limit 75-fold, 48-fold, 14-fold, respectively. Their correlated with those plants, but this not case Mn. Heavy metal...
The use of green extraction methods that meet the criteria sustainable and environmentally friendly technologies has been increasing in recent decades due to their many benefits. In this respect, extracts obtained using subcritical water are also gaining increased attention because potential antioxidant antimicrobial properties. Their activity is mainly presence various polyphenolic compounds. Although exact mechanism antibacterial action compounds not yet fully investigated described,...
Fungal infections of cultivated food crops result in extensive losses at the global level, while resistance to antifungal agents continues grow. Supercritical fluid extraction using CO2 (SFE-CO2) has gained attention as an environmentally well-accepted method, is a non-toxic, inert and available solvent, extracts obtained are, chemically, greater or different complexities compared those conventional extracts. The SFE-CO2 Achillea millefolium, Calendula officinalis, Chamomilla recutita,...
Abstract Objective To investigate the efficacy of 13 antimicrobial substances (11 natural origin and two conventional preservatives as controls) at concentrations in an o/w cosmetic emulsion. Methods Cosmetic formulations were analysed for total aerobic bacterial count combined yeast according to European Pharmacopoeia 8.0. Challenge tests performed ISO 11930 standard. Results The count, mesophilic microorganisms below acceptable limit all formulations. test criterion A was fulfilled by...
(Chenopodiaceae) is an under-investigated annual plant that occurs in dry areas stretching from eastern and south-eastern Europe to East Asia. This article presents the botanical characterization examination of proximate parameters, minerals cytotoxic activity
Elderberry (Sambucus nigra L.) hydrolate, derived from domestic steam distillation, holds promise as a multifunctional ingredient for skincare and cosmetic applications. This study investigates the chemical composition biological activities of elderberry hydrolate obtained through distillation. Despite growing interest in there has been lack comprehensive studies elucidating its potential bioactive constituents. To address this gap, we conducted detailed analysis hydrolate’s composition,...
The chemical composition of essential oils and hydrosols immortelle (Helichrysum italicum) stems with leaves obtained by hydrodistillation was identified using gas chromatography coupled mass spectrometry (GC-MS). One-year-old two-year-old plants the same population, from three Croatian populations, all grown in Slovenia, were included study. main compounds one-year-old α-pinene, α-eudesmol, rosifoliol. Among dominant components found: geranyl acetate, 2-phenylethyl tiglate. Both more...
Research on new, untapped seed oil sources is receiving increased attention. In this study, 18 different samples of Tilia cordata and platyphyllos from various locations in Slovenia were collected was extracted. The compositions triglyceride fatty acids unsaponifiable compounds determined using GC-MS, while antioxidant activity evaluated the DPPH method. content seeds varied significantly, 9.1% to 21.7%. Linoleic acid (50–60%) found be predominant acid, followed by oleic (18–22%) palmitic...
Norway spruce (Picea abies) is one of the most important commercial conifer species naturally distributed in Europe. In this paper, composition and abundance essential oil hydrosol from needles branches P. abies were investigated with an additional evaluation changes related to different times year, annual shoots branches, differences under microenvironments. Essential oils hydrosols obtained via hydrodistillation analyzed using gas chromatography–mass spectrometry (GC-MS), where 246...
Novel CE and HPLC methods for the determination of ALP in pharmaceutical dosage forms were developed, validated according to ICH guidelines, applied real samples, cross-validated greenness assessment was performed.

Hydrosols have been increasingly used in the food industries as drinks and ingredients for seasoning flavoring. Research has shown they antimicrobial, antioxidative anti-inflammatory effects therefore potential preservative agents sanitizing tools industry. The composition analysis of hydrosols is commonly conducted using extraction with organic solvents. However, some hydrophilic compounds are lost this procedure, leading to issues identifying native adulteration. In paper, different...
Abstract Echinacea purpurea is one of the most widely used immunostimulant plants. Its main active compounds are polysaccharides, glycoproteins, caffeic acid derivatives, alkamides, and melanins. The article describes an optimized extraction procedure that enables spectrophotometric quantification polysaccharides from purpurea. can be applied as it demonstrated to useful for determining polysaccharide content in flowers leaves, summer autumn plants, plants with green red stem, two different...
