Only registered users can translate articles

OBJECTIVE To determine the free radical scavenging potentials pytochemical constituents of ethanol leaves extracts of Allamanda cathartica (A. cathartica) and Bixa orellana (B. orellana) and thus their effects in antimalarial activities. METHODS Both ethanol extracted plant samples were administered

Implication of salt stress induces changes in pigment production, antioxidant enzyme activity, and qRT-PCR expression of genes involved in the biosynthetic pathway of Bixa orellana L.

Only registered users can translate articles

The effect of salt stress on pigment synthesis and antioxidant enzyme activity as well as in the genes involved in the biosynthetic pathway of bixin was studied. The 14-day germinated seedlings of Bixa orellana were induced into the various NaCl concentration (0, 25, 50, 75, 100 mM). After 45 days,

Mucilaginous polysaccharides from vegetative parts of Bixa orellana L.: Their characterization and antioxidant potential.

Only registered users can translate articles

The aim of this study was to extricate adhesive mucilaginous polysaccharides (MPS) from vegetative parts of Bixa orellana and furthermore to explore proximate analysis and antioxidant potentials. The ethanol precipitated mucilage concentrates of leaf holds 57.7% ± 3.2% moisture, 31.7 ± 1.61 g/100 g

Anti-oxidant and anti-inflammatory potential of aqueous extracts of leaves, barks and roots of Bixa orellana L. (Bixaceae) on acetaminophen-induced liver damage in mice

Only registered users can translate articles

Objective: Bixa orellana is a plant from the Bixaceae family, for which, limited information is available on hepatoprotective properties. This study aimed at evaluating the protective effects of this plant on sub-acute

Stability and Antioxidant Activity of Annatto (Bixa orellana L.) Tocotrienols During Frying and in Fried Tortilla Chips.

Only registered users can translate articles

Annatto tocotrienols (AnT3), which contain approximately 90% δ-tocotrienol (δ-T3), were added to mid-oleic sunflower oil used for frying tortilla chips over 3 d. The objectives were to evaluate their stability during frying, absorption by the fried food, and activity as antioxidants in frying oil

Annatto extract and β-carotene enhances antioxidant status and regulate gene expression in neutrophils of diabetic rats.

Only registered users can translate articles

Annatto (Bixa orellana L.) contains a mixture of orange-yellowish pigments due to the presence of various carotenoids that have antioxidant effect. The immune system is especially vulnerable to oxidative damage because many immune cells, such as neutrophils, produce reactive oxygen and nitrogen

Cosmetics, personal care and biomedical products obtained by bio-based polymers and natural bioactive compounds are a new growing market. The ecological awareness is changing consumers' demands, causing consumers to look for more sustainable options, with a reduced environmental impact. The

Effects of Annatto (Bixa orellana L.) Seeds Powder on Physicochemical Properties, Antioxidant and Antimicrobial Activities of Pork Patties during Refrigerated Storage.

Only registered users can translate articles

This study investigated the effect of the powder produced by ball-milling the outer layer of annatto (Bixa orellana L.) seeds on the physicochemical properties as well as the antioxidant and antimicrobial activities of pork patties over 14 d of refrigerated storage (4±1℃). Five pork patty treatments

Optimization of the Microwave-Assisted Extraction Process of Bioactive Compounds from Annatto Seeds (Bixa orellana L.).

Only registered users can translate articles

This study deals with the extraction, optimization, and evaluation of the antioxidant and antimicrobial activities of bioactive compounds obtained from the seeds of annatto using microwave-assisted extraction as compared to leaching. Annatto seeds were subjected to a microwave treatment of 2450 MHz

Safety and efficacy of Bixa orellana (achiote, annatto) leaf extracts.

Only registered users can translate articles

Bixa orellana leaf preparations have been used for many years by indigenous people for a variety of medicinal applications. Published research studies in animals indicate that various extracts of Bixa leaves exhibit antioxidant, broad antimicrobial (antibacterial and antifungal), anti-inflammatory,

Preliminary pharmacological screening of Bixa orellana L. leaves.

Only registered users can translate articles

Preliminary pharmacological studies were performed on the methanol extract of Bixa orellana L. (Bixaceae) leaves to investigate neuropharmacological, anticonvulsant, analgesic, antidiarrhoeal activity and effect on gastrointestinal motility. All studies were conducted in mice using doses of 125, 250

The biotechnology (genetic transformation and molecular biology) of Bixa orellana L. (achiote).

Only registered users can translate articles

UNASSIGNED Genetic transformation allows for greater bixin or norbixin production in achiote. Knowledge of genes that control the biosynthesis of these important secondary metabolites will allow for targeted amplification in transgenic plants. Annatto is a natural dye or coloring agent derived from

Targeting NRF2 for Improved Skin Barrier Function and Photoprotection: Focus on the Achiote-Derived Apocarotenoid Bixin.

Only registered users can translate articles

The transcription factor NRF2 (nuclear factor-E2-related factor 2) orchestrates major cellular defense mechanisms including phase-II detoxification, inflammatory signaling, DNA repair, and antioxidant response. Recent studies strongly suggest a protective role of NRF2-mediated gene expression in the

Effect of UV radiation and its implications on carotenoid pathway in Bixa orellana L.

Only registered users can translate articles

The current study was undertaken to analyse the effect of short-term UV-B and UV-C radiations in provoking carotenoid biosynthesis in Bixa orellana. Seeds of B. orellana were germinated and exposed to the short term UV pre-treatment under controlled environmental condition for 5days. The UV treated
