The vitamin compositions of fresh leaves of Cucurbital moschata and Amaranthus hybridus L. were determined through spectrophotometric and titrimetric methods. The investigation revealed that the fresh leaves of Cucurrbital moshcata contained higher amounts (mg/100g) of ascorbic acid (33.49±1.22), thiamine (17.38±2.06) and riboflavin (3.41±0.18) while Amaranthus hybridus contained higher amount ...

biology of amaranth stem-boring weevil, hypolixus pica (fabricius) on red root pigweed, amaranthus retroflexus l. was investigated under natural conditions in a citrus orchard in dezful. each red root pigweed was covered by a wooden cage of 50×50×100cm dimentions screened by muslin. three to four adult females and males were introduced into each cage. after 3-4 days past the weevils were remove...

The objective of this research was to evaluate the physicochemical characteristics Amaranthus spp. commonly happening in Brazil, besides defining efficiency different extraction processes phenolic compounds and antioxidant activity. Five species genus (A. spinosus, A. viridis, retroflexus, hybridus var. paniculatus e deflexus) were evaluated regard their such as vitamin C, soluble solids, pH, m...

Betalains in Amaranthus tricolor leaf were identified by means of reversed phase high-performance liquid chromatography (HPLC) and Liquid chromatography-Mass spectrometry (LC-MS). In addition to the known compound red-violet amaranthin, two yellow pigments were detected in Amaranthus tricolor. A novel betaxanthin, methyl derivative of arginine betaxanthin was identified on the basis of UV-Vis s...
