Ethanol-Based Extraction of Annatto (Bixa Orellana L.) and Characterization of the Bixin and Norbixin [PDF]
ACS OmegaBixa orellana dye was extracted from the seeds by the method of Soxhlet extraction using ethanol where a percentage yield of 31.4 was obtained. Recrystallization of the dye was performed using chloroform and ethanol to increase the degree of purity. Thin layer chromatography was used to separate the dye into Bixin and Norbixin with Rf values of 0.56 ...

Third- and fifth-order optical nonlinearities of norbixin
Results in Optics, 2022 In this work, we investigated the nonlinear response of norbixin (C24H28O4) in acetone. The third- and fifth-order optical nonlinearities were measured using the conventional Z-scan technique, with 357 fs laser pulses at 1040 nm and low-repetition rate ...

Structural analysis of unstable norbixin isomers guided by pure shift nuclear magnetic resonance
Magnetic Resonance in Chemistry, 2022 Abstract We report the analysis of complex samples obtained during the microwave irradiation/heating of norbixin, which has been identified as a potential therapeutic target for age‐related macular degeneration (AMD). In this context, identifying the different isomers that are obtained during its degradation is of

Morphological, Structural, and Thermal Properties of Microbial Carotenoids Microencapsulated by Spray-Drying Using Different Combinations of Wall Materials. [PDF]
J Food SciABSTRACT This study evaluated the spray‐drying encapsulation of carotenoid‐rich extracts produced by Sporidiobolus salmonicolor, with the optimization of a ternary wall system of gum arabic (GA), inulin (IN), and corn starch (ST). Carotenoids were produced in a semi‐continuous bioreactor, extracted with organic solvents, and microencapsulated by spray ...

Bromoacetate Olefination Protocol for Norbixin and Julia–Kocienski Olefination for Its Ester Syntheses [PDF]
ACS Omega, 2019 A new olefination protocol utilizing ethyl bromoacetate was highlighted, in which magnesium enolate of the ester coupled with C20 dialdehyde 6, and double eliminations of the protected hydroxyl groups and bromine atoms of the coupling bromohydrin product, efficiently produced norbixin 1 after concomitant hydrolysis of the ester.

Beyond AREDS Formulations, What Is Next for Intermediate Age-Related Macular Degeneration (iAMD) Treatment? Potential Benefits of Antioxidant and Anti-inflammatory Apocarotenoids as Neuroprotectors. [PDF]
Oxid Med Cell Longev, 2020 Age‐related macular degeneration (AMD) is the commonest cause of severe visual loss and blindness in developed countries among individuals aged 60 and older. AMD slowly progresses from early AMD to intermediate AMD (iAMD) and ultimately late‐stage AMD. Late AMD encompasses either neovascular AMD (nAMD) or geographic atrophy (GA).
