Cabralea canjerana and Cordia americana , two Brazilian tree species found across various states, serve a range of applications from sawmill products to folk medicine. The extractives, non-structural wood components, are utilized for diverse purposes, including natural dyes, preservatives, medicinal products. After comprehensive search the literature, no publications were characterizing chemical composition C. wood. This increases need research these learn more about their potential. vast diversity Brazil’s sometimes complicates selection process extraction highlighting importance anatomical identification. study evaluates presence fine molecules with important biological activity or industrial value in extractives proposing potential uses extracted lignocellulosic biomass providing identification support species. Characterization methods included analysis ash, hemicellulose, cellulose, lignin content. Extraction techniques employed ethanol, ethanol-toluene, hot water, 1% soda, followed by gas chromatography-mass spectrometry (GC-MS) analysis. Anatomical characteristics determined using histological slides. results show that displayed 53.61% holocellulose content relation dry mass, suitable paper production, while 55.92% content, was deemed even appropriate. GC-MS identified several significant Phenol, 2,4-bis(1-phenylethyl), which is potentially effective breast cancer drug development, Gestrinone, possible treatment endometriosis. examination samples confirmed identity, aligning study’s objectives.

The Amazonian region comprises a set of ecosystems that play an essential role in stabilizing global climate and regulating carbon water cycles. However, several environmental issues anthropogenic origin threaten stability this region: agribusiness, illegal mining, timber exports, pesticide use, biopiracy, among others. These actions lead to deforestation, soil erosion, fauna biodiversity loss, resource contamination, land conflicts, violence against indigenous peoples, epidemics. present study aims feature the current degradation process faced by biome identify strategic alternatives based on science inhibit minimize its resources. This applied research, systematic review, highlighted complexity, fragility, importance functioning ecosystem. Although activities such as mining agriculture notoriously cause degradation, research focused scenarios degradation. dynamics Amazon associated with human activity change advancement were also described. Ultimately, emphasizes that, given invaluable Amazon’s natural resources for balance food security, threats endanger sustainability. Beyond well-known human-induced impacts forest life, findings highlight need strategies integrate conservation, sustainable management, public policies region’s development. strategies, supported partnerships, include reducing deforestation burning, promoting education, engaging local communities, enforcing policies, conducting continuous monitoring using satellite remote sensing technology.

Food production’s environmental, economic, and social challenges should be demystified through quantitative data. Therefore, the objective of this paper was to investigate ecoregional sustainability Amazon biome from perspective environmental life cycle, economic feasibility, cycle analysis, emphasizing pillars in production three commodities: soybean, beef cattle, Brazil nuts. Carbon footprint, net present value, worker endpoint were metrics evaluated. According results found study, livestock presented greater burdens terms carbon balance when compared nuts soybean with balances order 4.75 tCO2eq/ha, −0.02 −1.20 respectively. From an viewpoint, extractive highest profit per hectare/year (USD 559.21), followed by agricultural system 533.94) 146.19).
