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...
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 international tendency for growing and production of small fruits shows a permanent increasing. Bulgaria is traditional important producer berries in Europe. A large variety fruit products are wide spread typical Bulgarian nutriment. Aside with the demand fruit, there an obvious food quality, breeding technology requirements improvement. Breeding purposes comprise improvement many traits, but selection disease resistant cultivars, higher yield improved consumers properties such as color,...
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...
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...
Pistacia palaestina hosts several Fordini gall-forming aphid species, which manipulate its anatomy and metabolism, creating galls that provide nutrients protection. This study compared the extended metabolic profiles of P. leaves induced by Baizongia pistaciae, Paracletus cimiciformis, Geoica spp. GC–MS analysis ethyl acetate (EtOAc) methanol (MeOH) extracts revealed a high abundance shikimic acid quinic isomers, along with diverse hydrocarbons, lipids, terpenoids, phenolics, carbohydrates,...
This study explores the antiviral potential of Graptopetalum paraguayense (GP) against SARS‐CoV‐2 nonstructural proteins (NSPs). GP, a plant known for its health benefits, has previously shown strong activity HSV‐1, and although two viruses have different taxonomy, effectiveness new coronavirus was also examined. LC‐ESI‐QTOF‐MS/MS analysis identified fourteen polyphenolic metabolites in including procyanidins flavonol glucosides, compounds associated with anti‐coronavirus properties. These...
ABTRACTOver the past 10 years, researchers have become increasingly interested in polyphenols. The main reason for this interest is recognition of antioxidant properties polyphenols, their great abundance our diet, and probable role prevention various diseases associated with oxidative stress, such as cancer, cardiovascular neurodegenerative (51). Furthermore, which constitute active substances found many plants, modulate activity a wide range enzymes cell receptors (1). In way, addition to...

Sambucus ebulus L. (SE) fruits are used for their immunostimulation, hematopoietic and antiviral potential. Recently, we focused on analyzing the mechanism underlying SE fruit aqueous extract's (FAE) immunomodulation anti-inflammatory activities, with attention to its endoplasmic reticulum (ER) stress-reducing J774A.1 macrophages were treated FAE alone or in conditions of lipopolysaccharides (LPS) stimulation. Using GC-MS LC-MS/MS, phytochemical composition was analyzed. To measure...
A comparative investigation of n-hexane soluble compounds from aerial parts dandelion (Taraxacum officinale Weber ex F.H. Wigg.) collected during different vegetative stages was carried out. The GC-MS analysis the (unpolar) fraction showed presence 30 biologically active compounds. Phytol [14.7% total ion current (TIC)], lupeol (14.5% TIC), taraxasteryl acetate (11.4% β-sitosterol (10.3% α-amyrin (9.0% β-amyrin (8.3% and cycloartenol (5.8% TIC) were identified as major components in...
Plant tissue cultures have been widely used in both fundamental and applied types of research on various biological species, the scientific interest to transfer that technology industrial scale has rapidly growing. The use vitro for commercial propagation different plant species production bioactive compounds from them become profitable industry worldwide. In past decades, progress culture was directed towards introduction liquid medium cultivation under submerged conditions bioreactor...
Sambucus ebulus (SE) fruits are used for immune stimulation and amelioration of gastrointestinal inflammatory conditions. Currently, there is no scientific evidence their effects on various aspects the response mechanisms in humans. The purpose this study was to evaluate immunomodulatory potential SE fruit infusion intake healthy Anthocyanin content determined with UPLC-ESI-MS/MS. Fifty-three volunteers enrolled a 4-week intervention. Blood count, serum total protein, Interleukin 1 beta...
Essential oils and hydrosols of two cultivars muscadine grapes (Muscadinia rotundifolia (Michx.) Small.) were obtained by hydro-distillation flowers berry skins. Twenty-three volatile compounds identified in essential from the flowers, twenty volatiles their corresponding hydrosols. The composition skins differed significantly that vine flowers. antioxidant potential investigated was evaluated using five vitro assays: DPPH (2,2-diphenyl-1-picrylhydrazyl) method, TEAC (Trolox equivalent...
Augmented knowledge of plant responses upon application stress could help improve our understanding tolerance under abiotic conditions. Histone acetylation plays an important role in gene expression regulation during growth and development the response plants to stress. The current study examines level transcripts free metabolite content transgenic Arabidopsis thaliana expressing a encoding histone acetyltransferase from Medicago truncatula (MtHAC1) after its heterologous expression. Stable...
