Antioxidant activity and phenolic compounds of 112 traditional Chinese medicinal plants associated with anticancer
TLDR
Traditional Chinese medicinal plants associated with anticancer might be potential sources of potent natural antioxidants and beneficial chemopreventive agents, and contain significantly higher levels of phenolics than common vegetables and fruits. Expand
Antioxidant capacity of 26 spice extracts and characterization of their phenolic constituents.
TLDR
This study provides direct comparative data on antioxidant capacity and total and individual phenolics contents of the 26 spice extracts and showed that phenolic compounds in the tested spices contributed significantly to their antioxidant capacity. Expand
Antioxidant activity of betalains from plants of the amaranthaceae.
TLDR
Antioxidant activity of betalain pigments from plants of the family Amaranthaceae was evaluated using the modified DPPH(*) (1,1-diphenyl-2-picrylhydrazyl) method and the relationship between the chemical structure and the activity of the betalains was investigated and discussed. Expand
Anthocyanins, flavonols, and free radical scavenging activity of Chinese bayberry (Myrica rubra) extracts and their color properties and stability.
TLDR
Both DPPH* and ABTS*(+) cation assays indicated that the black varieties (Biji and Hunan) demonstrated much higher radical scavenging activities than the pink (Fenhong) and yellow (Shuijing) varieties, which may be attributed to much higher levels of anthocyanins, flavonoids, and total phenolics in theblack varieties.

Hypoglycemic and hypolipidemic effects and antioxidant activity of fruit extracts from Lycium barbarum.
TLDR
It was found that the three Lycium barbarum fruit extracts/fractions could significantly reduce blood glucose levels and serum total cholesterol (TC) and triglyceride (TG) concentrations and at same time markedly increase high density lipoprotein cholesterol (HDL-c) levels after 10 days treatment in tested rabbits, indicating that there were substantial hypoglycemic and hypolipidemic effects. Expand
Extraction and purification of squalene from amaranthus grain.
TLDR
A method to isolate and purify the squalene from Amaranthus oil was developed, and the structure ofSqualene in the purified sample was confirmed by comparison of its ultraviolet spectrum with a standard and from its nuclear magnetic resonance spectra. Expand
Gallic acid suppresses cell viability, proliferation, invasion and angiogenesis in human glioma cells.
TLDR
Data suggest that suppression of ADAM17 and downregulation of PI3K/Akt and Ras/MAPK signaling pathways may contribute to gallic acid-induced decrease of invasiveness and may be a valuable candidate for treatment of brain tumor. Expand
Antioxidant phenolic constituents in roots of Rheum officinale and Rubia cordifolia: structure-radical scavenging activity relationships.
TLDR
The structure-radical scavenging activity relationships of the tested hydroxyanthraquinones were systematically demonstrated as follows: Hydroxy groups on one benzene ring of the anthraquinone structure were essential for hydroxyrthraquones to show activity, the ortho-dihydroxy structure in the hydroxianthra Quintone molecules could greatly enhance their radical scavenging effect, and glycosylation of the hydroxy groups reduced activity. Expand
Field evaluation of an Amaranthus genetic resource collection in China
A total of 229 genotypes of 20 Amaranthus species from the United States Department of Agriculture – Agricultural Research Service (USDA – ARS) National Plant Germplasm Amaranth Collection wasExpand
HPLC characterization of betalains from plants in the amaranthaceae.
TLDR
Three betxanthins were separated from Celosia species in the Amaranthaceae and identified to be immonium conjugates of betalamic acid with dopamine, 3-methoxytyramine, and (S)-tryptophan; the latter two are found to be new betaxanthins from plants. Expand
