In vitro antioxidant properties of 3 different extracts of black mulberry (Morus nigra L.) were investigated. Acidified methanol, acidified water, and non-acidified methanol/water solutions were used to prepare extracts. Different solvents caused different protonation on black mulberry anthocyanin structures, which were predicted according to their UV-VIS spectrum. Extracts indicated 2 main pea...

The Effects of Stone Fruit Extract on the Process of Platelet Aggregation in Vitro. (July 2011) Peter M. deLeeuw Department of Biomedical Sciences Texas A&M University Research Advisor: Dr. Luis Cisneros-Zevallos Department of Horticulture This project attempts to examine the impact stone fruits can have on the clotting of blood in the human body. Plum rich anthocyanin extract (RAE) was added i...

Anthocyanins are flavonoid compounds that protect plant tissues from many environmental stresses including high light irradiance, freezing temperatures, and pathogen infection. Regulation of anthocyanin biosynthesis is intimately associated with environmental changes to enhance plant survival under stressful environmental conditions. Various factors, such as UV, visible light, cold, osmotic str...

Production of anthocyanins is one of the adaptive responses employed by plants during stress conditions. During stress, anthocyanin biosynthesis is mainly regulated at the transcriptional level via a complex interplay between activators and repressors of anthocyanin biosynthesis genes. In this study, we investigated the role of a NAC transcription factor, ANAC032, in the regulation of anthocyan...

in order to optimize callus induction in pistacia atlantica desf. subsp. kurdica rech. f., the effect of different plant growth regulator (pgr) combinations were studied. inflorescence axis explants were cultured on wpm medium supplemented with 1, 2 and 3 mg/l of tdz or 1, 2 and 3 mg/l of ba, in combination with 1mg/l different auxins: 2, 4-d,  naa  and iba . callus initiation was observed in a...

Background & Aims: Plants contain high antioxidant activities due to their redox and the chemical properties are affluent in secondary metabolites such as phenols, flavonoids, and other components. Rheum turkestanicum Janisch is a plant from polygonaceae that is widely used for diabetes. At this project that is a part of national thesis, relative levels of antioxidant activity, total phenols, t...

Smart film from jackfruit seeds containing anthocyanin extract has potential application as a freshness indicator of fish they deteriorate, changing the color function product pH. The lower solubility percentage films was evidenced by volume. presented mean water vapour permeability values 3.034 g.mm/kPa.h.m2. starch/anthocyanin (ST4.0:AN5.0) showed higher tensile strength, while ST2.4:AN5.0 an...
