In order to investigate the mutation characteristics and to further examine the genetic variation of mutant sunflower (Helianthus annuus) obtained in plants grown from seeds exposed to space conditions, only the mature tissues such as leaf and flower could be used for DNA extraction after mutation characteristics were confirmed. The rich contents of polysaccharides, tannins, secondary metabolit...

Sweet cherries (Prunus avium L.) contain various phenolic compounds which contribute to total antioxidant activity. Total polyphenols, tannins, flavonoids and anthocyanins, and antioxidant capacity in a fruits of a number of selected sweet cherry genotypes were investigated. Total polyphenols content ranged from 4.12 to 8.34 mg gallic acid equivantents/g dry fruit weight and total tannins conte...

Th is work compares the polyphenolic compounds content in the in vitro shoot cultures of Hypericum rumeliacum, H. tetrapterum and in the hypericin non-producing H. calycinum, which are characteristic for the Balkan fl ora. In addition, the impact of diff erent vitamin supplementation to culture medium on secondary metabolites is discussed. Th ough Gamborg’s vitamins supplementation improved gro...

A variety of consumable plant-derived phytochemicals exhibit nutraceutical properties because they produce physiological benefits and combat disease processes. Emerging evidence suggests that widely accessible and safe organic polyphenolic phytochemicals, in particular, treat depression at much lower concentrations than clinical doses of classical drugs. Structurally similar polyphenolics such ...

CULINARY HERBS AND SPICES by REBECCA P. DEARLOVE (Under the Direction of James L. Hargrove, Ph.D.) ABSTRACT Diabetes mellitus is a metabolic disorder characterized by a deficiency and/or absence of insulin that is associated with chronic pathology including retinopathy, nephropathy, neuropathy and atherosclerosis. These diabetic complications are caused in part by the build-up of advanced glyca...

The changes in total polyphenolics in elderberry (Sambucus nigra) following treatment with various doses of pulsed ultraviolet rays (UV) were investigated. Four pulsed UV durations (5, 10, 20, 30 seconds) at three energy dosages (4500, 6000, 11,000 J/m/pulse) were considered for the research. All treated elderberry fruits were incubated for 24 h at room temperature (25 ̊C) following treatment to...
