A sustainable extraction approach for recovery of Rhamnogalacturonan I enriched pectin from Amazonian cocoa pod husk.

Approximately 16,000 thousand tonnes of cocoa husk are produced annually worldwide during the chocolate production chain, representing considerable potential for pectin extraction. The aim of this study was to investigate a new extraction technique using a binary system composed of carbon dioxide and water (CO + HO) at high pressure and temperature, on cocoa sample from floodplain ecosystem. Temperatures of 393.

Elucidating the Mesocarp Drupe Transcriptome of Açai ( Mart.): An Amazonian Tree Palm Producer of Bioactive Compounds.

palm, endemic to the Amazon region, is well known for açai, a fruit violet beverage with nutritional and medicinal properties. During fruit ripening, anthocyanin accumulation is not related to sugar production, contrarily to grape and blueberry. Ripened fruits have a high content of anthocyanins, isoprenoids, fibers, and proteins, and are poor in sugars.

Discriminating Aroma Compounds in Five Cocoa Bean Genotypes from Two Brazilian States: White Kerosene-like Catongo, Red Whisky-like FL89 (Bahia), Forasteros IMC67, PA121 and P7 (Pará).

Fine-grade cocoa beans are characterized by their great organoleptic quality. Brazilian cocoa producers increasingly privilege organoleptic quality over yield. Catongo and FL89, fine Brazilian cocoa genotypes from Bahia, are characterized by particular flavors (respectively, kerosene and whisky).

Extract of Martius Stone Presents Anticonvulsive Activity the GABAA Receptor.

Epilepsy is one of the most common neurological diseases globally, resulting from a disorder in brain activity. This condition can be triggered by birth trauma, traumatic brain injury (TBI), infections of the brain and stroke. More than 70 million people suffer seizures caused by neurological abnormalities.

Myorelaxation, respiratory depression and electrocardiographic changes caused by the administration of extract of açai ( Mart.) stone in rats.

The biological and pharmacological properties of natural polyphenols of the extract of stone (EEOS) are associated with the central nervous system (CNS). To investigate the sedative and myorelaxant activity of EEOS , this study aimed to present the myorelaxant and sedative effects of EEOS in Wistar rats using spontaneous locomotor activity and motor electrophysiology. A total of 108 animals were used in the following experiments: a) behavioral tests (n = 27); b) electromyographic recordings of skeletal muscle (n = 27); c) respiratory muscle activity recordings (n = 27); d) cardiac muscle activity recordings (n = 27).

Isolation and Genetic Identification of Endophytic Lactic Acid Bacteria From the Amazonian Açai Fruits: Probiotics Features of Selected Strains and Their Potential to Inhibit Pathogens.

The açai palm () is native to the Amazon basin, a humid tropical forest. High levels of total mesophilic bacteria with high diversity have been consistently reported in açai fruits. As local consumers have few digestive problems, the results of the present study reveal the lactic acid bacteria (LAB) recovered from açai fruits with characteristics that suggest they are possible candidates for probiotics and antagonistic potential against pathogens for the first time.

Secure and Sustainable Sourcing of Plant Tissues for the Exhaustive Exploration of Their Chemodiversity.

The main challenge of plant chemical diversity exploration is how to develop tools to study exhaustively plant tissues. Their sustainable sourcing is a limitation as bioguided strategies and dereplication need quite large amounts of plant material. We examine if alternative solutions could overcome these difficulties by obtaining a secure, sustainable, and scalable source of tissues able to biosynthesize an array of metabolites.

Genipap (Genipa americana L.) juice intake biomarkers after medium-term consumption.

Genipap (Genipa americana L.) is an exotic fruit largely consumed and well known, in Amazonian pharmacopeia, to treat anemia, measles and uterine cancer. It is also used as a diuretic, digestive, healing, laxative and antiseptic.

Obtainment of an enriched fraction of : identification using UPLC-DAD-MS/MS and photochemopreventive screening.

is a fruit tree native from Central and South America. Different species of have demonstrated high polyphenolic content and high antioxidant capacity. The oxidative stress significantly contributes to the development of several chronicle diseases, particularly age-related diseases.

Cecropia obtusa extract and chlorogenic acid exhibit anti aging effect in human fibroblasts and keratinocytes cells exposed to UV radiation.

Cecropia obtusa is popularly used in the Amazonian region and exhibits antioxidant activity. Cosmetic formulations containing C. obtusa extract are commercially available for purchase; however, the chemical composition and the effects of the topical application of the extract are not described in the literature.

Main Human Urinary Metabolites after Genipap ( L.) Juice Intake.

Genipap ( L.) is a native fruit from Amazonia that contains bioactive compounds with a wide range of bioactivities. However, the response to genipap juice ingestion in the human exposome has never been studied.
