Delimitation of Amaranthus cruentus L. and Amaranthus caudatus L. using micromorphology and AFLP analysis: an application in germplasm identification

open access: yesGenetic Resources and Crop Evolution, 2006
The ‘Morelos’ accessions of Amaranthus from Mexico demonstrate taxonomic ambiguity at the basic morphologic level. The main cause is the enormous morphological and genetic variation exhibited by the species in the genus.

PHYTO-REMEDIATION OF LEAD-CONTAMINATED SOIL USING AMARANTHUS CRUENTUS [PDF]

open access: yes, 2005
Previous studies have shown that some vegetables have the ability to absorb metals from soil. Since they are early maturity species, they possess the potential to be used as phytoremediating agents. Also, synthetic chelates have been found to induce lead desorption from soil matrix, thereby enhancing uptake into plant tissues.

Morphological Studies on Amaranthus cruentus

Journal of Food Science, 1981
ABSTRACT The morphology of Amaranthus cruentus was studied using scanning election and light microscopy. The A. cruentus seed consists of a single layer of cells which is intimately associated with the perispeim.

Triterpenoid saponins from the seeds of amaranthus cruentus

Phytochemistry, 1998
Abstract Four new saponins, 3-β-O-[α- l -rhamnopyranosyl(1 → 3)-β-glucuronopyranosyl]-2β,3β-dihydroxyolean-12-en-28-oic acid 28-O-[β- d -glucopyranosyl] ester, 3-β-O-[α- l -rhamnopyranosyl(1 → 3)-β-glucuronopyranosyl]-2β,3β,23-trihydroxyolean-12-en-28-oic acid 28-O-[β- d -glucopyranosyl] ester, 3-β-O-[α-rhamnopyranosyl(1 → 3)-β-glucuronopyranosyl]-2β,

Determination and Toxicity of Saponins from Amaranthus cruentus Seeds

Journal of Agricultural and Food Chemistry, 1999
The concentrations of four triterpene saponins present in amaranth seeds were determined with high-performance liquid chromatography. It was shown that the total concentration of saponins in seeds was 0. 09-0.1% of dry matter. In germinating seeds an increase in concentration to 0.18% was observed after 4 days of germination, which remained stable for ...

A trypsin inhibitor from amaranth (Amaranthus cruentus) leaves

Applied Biochemistry and Microbiology, 2000
A protein that inhibited the proteolytic activity of trypsin was isolated from amaranth leaves (Amaranthus cruentus) by affinity chromatography on trypsin-Sepharose. The inhibition was noncompetitive (withp-nitroanilide-N-α-benzoyl-DL-arginine as substrate) and had aK i, of 1.87 × 10−7 M.

Physicochemical Characterization of Starches from Amaranthus Cruentus Grains

Starch - Stärke, 1998
The physicochemical properties of starches isolated from three cultivars (Mexican, African and A200D) of Amaranth cruentus grains were studied. The yield of starch was in the range 29–38.3% on a whole grain basis. The starch granules were polygonal with smooth surfaces. The granule size was in the range 0.75–1.5 μm for all three cultivars.
