Comparative Study of Betacyanin Profile and Antimicrobial Activity of Red Pitahaya (Hylocereus polyrhizus) and Red Spinach (Amaranthus dubius)

, 2016
Betacyanins are reddish to violet pigments that can be found in red pitahaya (Hylocereus polyrhizus) and red spinach (Amaranthus dubius). This study investigated the impact of sub-fractionation (solvent partitioning) on betacyanin content in both plants.

Optimization of Bioactive Compound and Phytochemical Extraction From Prickly Pear (Opuntia ficus-indica) Fruit Through Ultrasound‐Assisted Extraction (UAE)

Journal of Food Processing and Preservation, Volume 2025, Issue 1, 2025.
Opuntia ficus-indica (prickly pear fruit, PPF) as a rich source of natural antioxidants and colorants was aimed to be extracted (PPFE) through optimization by response surface methodology and central composite design (CCD) using ultrasound‐assisted extraction (UAE). The effects of independent variables including ethanol concentration (0%, 24%, 48%, 72%,

In vitro, in vivo, and in silico evidence for the use of plant pigments betalains as potential nutraceuticals against Alzheimer's disease

Food Frontiers, Volume 5, Issue 5, Page 2137-2154, September 2024.
Abstract Anti‐amyloidogenic properties of plant pigments betalains as potential nutraceuticals against Alzheimer's disease have been screened using 24 pure molecules. Twenty‐two betalains reduced amyloid aggregation in vitro, eight of them up to 100%, with IC50 values in the micromolar range.
