In the last decade, special attention has been paid to Artemisia (L.) genus plants, possibilities of using their medicinal raw material for therapeutic purposes. The aim research was determine variability phenolic compounds in four introduced L. species and evaluate antioxidant activity extracts vitro. highest total amount (297.37±9.18 mg RE/g DW) flavonoids (77.73±7.40 evaluated via spe...

The use of poly(N-vinyl-2-pyrrolidone) (PVP) hydrogel-supported luminol chemiluminescence (CL) for the automatic determination of hydrogen peroxide and the quantification of the antiradical capacity of Trolox is described. The hydrogel containing luminol and hemin is prepared directly on a 96-well microplate and can be stored for up to 3 months without significant decrease in CL quantum yields....

Aromatic plants and essential oils have many applications in medicine, pharmaceuticals, cosmetics, the food industry. The oil of flowering aerial parts Achillea grandifolia, obtained by hydrodistillation, was analyzed for its constituents investigated antimicrobial radical scavenging activity. characterized a high amount oxygenated monoterpenes (72.7%) with 1,8-cineole (29.2%) camphor (23.4%) b...

In recent years, there has been an ever-increasing interest in the research of polyphenols obtained from dietary sources, and their antioxidative properties. The purpose of this study was to determine the effect of boiling buckwheat and barley groats on the antioxidant properties and dietary fiber composition. Antioxidative properties were investigated using methyl linoleate model system, by as...

The purpose of this work is the synthesis new isonicotinic acid hydrazones, study their structure, reactivity and biological screening some synthesized compounds. reactions leading to N-arylidene(alkylidene) hydrazones via condensation hydrazide with various derivatives aromatic aldehydes were studied. structure functionally substituted was established by FTIR, 1H 13C NMR, two-dimensional COSY ...

The present work deals with the research of chemical constituents and evaluation antioxidant properties Bebotho propolis. From ethyl acetate extract, we isolated, using various chromatographic techniques, a mixture two identical compounds (isomers) indexed PBy4a PByb. structures these were elucidated by means spectroscopic analysis techniques (MS, IR, 1H-NMR, 13C-NMR, HMBC HSQC) comparison spec...

In present study, the comparative in vitro free radical scavenging activities of methanol extracts from three indigenous medicinal plants viz. Amla, Bitter gourd and Neem were evaluated by 1, 1-diphenyl-2-picryl-hydrazil (DPPH) radical scavenging method. Ascorbic acid was used as the reference. All of the plant extracts exhibited promising antiradical effects in a concentration dependent manner...
