This study presents a comprehensive phyto- and histochemical analysis of three Colchicum species: autumnale L., the Balkan endemic bivonae Guss., Bulgarian diampolis Delip. et Česchm. Using gas chromatography-mass spectrometry (GC-MS), 66 metabolites were identified, encompassing free amino, organic, phenolic, fatty acids, sugars, alkaloids, which distributed among various plant parts. Organ-specific metabolic patterns revealed that corms seeds are particularly rich in supporting their roles...
Antioxidants from natural sources are essential for the development of new therapeutics to improve human health. The objects study aerial flowering parts Potentilla argentea, a plant species known in traditional medicine astringent, hemostatic, wound-healing, and anti-inflammatory effects its rhizomes. A Potentillae argenteae herba ethanol dry tincture was chromatographically analyzed (GC/MS, HPLC) antioxidant (ABTS, DPPH, CUPRAC, FRAP assays) DNA nicking protection potentials were...
This paper reviews the recent development of scientific, legislative, economic and environmental aspects plant organic farming. The impact farming on biodiversity soil fertility is discussed in comparison with conventional systems. A significant barrier for wide application future existing diversity national international policy instruments this sector. Special attention paid to up-to-date research techniques that could help solve a number problems typically faced It argued still not...
The objective of this study was to assess the biological activity essential oils (EOs) four
The volatile compounds of eight peach varieties (Prunus persica L.)-"Filina", "Gergana", "Ufo-4", "July lady", "Laskava", "Flat Queen", "Evmolpiya", and "Morsiani 90"-growing in Bulgaria were analyzed for the first time. Gas chromatography-mass spectrometry (GC-MS) analysis HS-SPME technique revealed presence 65 compounds; main identified components aldehydes, esters, fatty acids. According to provided principal component (PCA) hierarchical cluster (HCA), relative quantities depended on...
Hemp (Cannabis sativa L.) is currently one of the most controversial and promising crops. This study compared nine wild hemp (C. spp. spontanea V.) accessions with 13 registered cultivars, eight breeding lines, cannabidiol (CBD) strain belonging to C. L. The first three groups had similar main essential oil (EO) constituents, but in different concentrations; CBD a EO profile. concentration four major constituents industrial lines varied as follows: β-caryophyllene 11–22% 15.4–29.6%;...
Biotechnologies based on microbial species capable of destroying harmful pollutants are a successful way to solve some the most important problems associated with clean environment. The subject investigation is Antarctic fungal strain Aspergillus glaucus AL1. culturing examined was performed 70 mg wet mycelium being inoculated in Czapek Dox liquid medium containing naphthalene, anthracene, or phenanthrene (0.3 g/L) as sole carbon source. Progressively decreasing naphthalene and anthracene...
Sustainability, becoming essential for food processing and technology, sets goals the characterization of resources considered as waste. In this work, information about GC-MS metabolites peach peels was provided a tool that can shed more light on studied biological activities. addition, distribution patterns contribution chemical profile free bound phenolic compounds antioxidant, antimicrobial, enzymatic clusters in different varieties Bulgarian origin were studied. The two applied...
The hypothesis of this study was that we can modify the essential oil (EO) profile hemp (Cannabis sativa L.) and obtain fractions with differential composition antimicrobial activity. Therefore, objective to evaluate effects grinding biomass before EO extraction fractionation during distillation on generated a several diversity chemical highest concentrations β-pinene myrcene in be obtained 5–10 min time (DT) ground material or 80–120 DT nonground material. High δ-3-carene limonene from 0–5...
The inhibition of certain digestive enzymes by target food matrices represents a new approach in the treatment socially significant diseases. Proving ability fruits to inhibit such can support inclusion specific varieties daily diets patients with diabetes, obesity, Alzheimer’s disease, etc., providing them much more than just valuable micro- and macromolecules. current study aimed atidentifying comparing GC-MS metabolic profiles eight peach (“Filina”, “Ufo 4, “Gergana”, “Laskava”, “July...
Hypericum species and especially H. perforatum L. are well known for their therapeutic applications. The present study assessed the essential oil (EO) composition, antifungal aphid suppression activity of seven Bulgarian species. EOs were analyzed by GC-MS-FID. Two experiments conducted. In first experiment, perforatum, maculatum, hirsutum used. Additionally, EO composition extracted via hydrodistillation (ClevA) commercial steam distillation (Com) compared. second experiment compared...
The genus Nepeta, belonging to the family Lamiaceae, includes about 300 species, most of which are used in folk medicine due their pronounced biological properties. aim present study was evaluate agrobiological characteristics Nepeta transcaucasica (N. transcaucasica) Grossh. and cataria cataria) L., cultivated Bulgaria, obtain essential oils determine antimicrobial antioxidant activities. two species growing Kazanlak were analyzed; therefore, high variability population N. comparative...
Essential oils (EOs) extracted from aromatic and medicinal plants have the potential to inhibit growth of various pathogens and, thus, be useful in control dangerous diseases. The application environmentally friendly approaches protect agricultural forestry ecosystems invasive hazardous species has become more significant last decades. Therefore, identification characterization essential with a strong inhibitory activity against aggressive widespread are key importance plant protection...
Wild berry species are known to exhibit a wide range of pharmacological activities. They have long been traditionally applied for their antiseptic, antimicrobial, cardioprotective and antioxidant properties. The aim the present study is reveal potential selective antiviral activity total methanol extracts, as well that anthocyanins non-anthocyanins from following wild berries picked in Bulgaria: strawberry ( Fragaria vesca L.) raspberry Rubus idaeus Rosaceae plant family, bilberry Vaccinium...
Juniperus excelsa M. Bieb and J. sabina L. contain essential oil (EO), while also contains podophyllotoxin, which is used as a precursor for anti-cancer drugs. Two studies were conducted. The first assessed the variability in EO profile podophyllotoxin concentration of two junipers, depending on location tree gender. main constituents α-cedrol, α-limonene α-pinene, sabinene, terpinen-4-ol, myrtenyl acetate α-cadinol. yield 18 accessions was 0.07–0.32% (w/w), but this not found any...
The purpose of the current study was to identify and quantify triterpenoids other non-polar compounds in leaves three high bush blueberry cultivars (Vaccinium corymbosum L. var. Bluegold, Bluecrop Elliott) natural populations Vaccinium species uliginosum L., myrtillus vitis-idaea L.) by means gas chromatography mass spectrometry (GC-MS) high-performance liquid with diode array detector (HPLC-DAD). Metabolite profiles differed significantly among analyzed, as well same species. V....
Aronia melanocarpa L. (black chokeberry), belonging to the Rosaceae family, contains high amounts of polyphenolics and therefore exhibits one highest antioxidant anti-inflammatory activities among berry fruits. Chokeberries are used in food industry for juice, nectar, wine production as colorants. We aimed compare phytochemical composition three chokeberry juices commercially available local market sources beneficial phytochemicals. Using GC-MS LC-MS/MS, we performed identification...
Nowadays, interest in natural antioxidants (especially phenolics) for the prevention of oxidative stress-related diseases is increasing due to their fewer side effects and more potent activity than some synthetic analogues. New chemical pharmacological studies well-known herbal substances are among current trends medicinal plant research. Meadowsweet (
