From Traditional Amazon Use to Food Applications: Tapirira guianensis Seed Extracts as a Triad of Antiproliferative Effect, Oxidative Defense, and Antimalarial Activity

Myuki Alfaia Esashika Crispim Thyele Chaves da Silva Amanda dos Santos Lima Laura da Silva Cruz Nathália Alves Bento

Tapirira guianensis is a tropical plant from South America widely used by indigenous communities due to its medicinal properties. The seeds are rich in phenolic compounds known for their anti-inflammatory, antioxidant, and antimicrobial properties. This study investigated the chemical composition, antioxidant potential, cytotoxic effects, and antimalarial properties of hydroethanolic, ethanolic, and aqueous seed extracts. The combination of water and ethanol (1:1) in the extraction proved to be efficient in obtaining bioactive compounds, resulting in the highest phenolic compound content and strong antioxidant activity. In addition, it reduced the viability of cancer cells, protected against damage caused by reactive oxygen species (ROS), decreased chromosomal aberrations, and proved to be highly effective against sensitive and resistant to chloroquine Plasmodium falciparum strains. These data indicate a promising profile of T. guianensis seed extracts in cytoprotective, antiproliferative, antioxidant, and antimalarial properties and point to the need for additional in vivo studies to better understand their mechanisms of action and safety.

Advances in Agricultural Technology: A Review of Slow-Release Nanofertilizers and Innovative Carriers

Communications in Soil Science and Plant Analysis (2024)

Helder Belato Espindola Sales Adriano de Souza Carolino Ronald Zico de Aguiar Nunes Célio Matias Airone Macalia Camila Macena Ruzo

Nanofertilizers represent a promising and innovative solution in modern agriculture, offering sustainability and efficiency to improve crop performance and optimize natural resource utilization. These fertilizers are distinguished by their nanometer-sized particles, facilitating better absorption and utilization by crops. A notable approach in nanofertilizer formulation is the controlled release of nutrients, ensuring a steady and gradual availability of essential elements to plants throughout their growth cycle. This approach curtails excessive fertilizer application, reduces leaching, minimizes negative environmental impact, and enhances nutrient utilization efficiency. Innovative carriers, in turn, play a fundamental role in the precise delivery of nutrients. Eco-friendly materials are being explored as sustainable alternatives to encapsulate the nutrients, ensuring they are available to plants when needed. This not only contributes to the preservation of natural resources but also reduces the negative environmental impacts associated with conventional agriculture. Therefore, this review article highlights promising advancements in agricultural technology, with a focus on the utilization of slow-release nanofertilizers and innovative carriers as sources of essential nutrients such as nitrogen, phosphorus, and potassium in agricultural practices, emphasizing the use of these technologies to promote environmental sustainability and agricultural efficiency.

Pedra-ume caá fruit: An Amazon cherry rich in phenolic compounds with antiglycant and antioxidant properties

Food Research International (2019)

Andrezza S. Ramos Josiana Moreira Mar Laiane Souza da Silva Leonard Domingo Rosales Acho Bárbara Janaína P. Silva

Species of Eugenia have been used as an antidiabetic natural source. Chemical, antioxidant and antiglycant screening of extracts from pedra-ume caá (Eugenia punicifolia) fruits were performed. 1H NMR assisted by non-supervised chemometric methods were employed for the evaluation of the chemical profiles which were distinguished according to the color of fruit maturation stages, as well as for pulp and seed fruit. Furthermore, 1H NMR fingerprint analysis of the crude extract allowed the identification of quercitrin and myricitrin, beside other nine compounds. The extracts of the yellow (YP) and green (GP) pulps presented higher antiglycant and antioxidant activities. Fresh juice from E. punicifolia was encapsulated in microcapsules produced with dextrose equivalent (DE) of 10, 20 or 30 as wall materials for the maintainment of their antioxidant and antiglycant properties. The more efficient retention of the bioactive compounds was found using the DE30. The Encapsulation Efficiency (EE) and the Retention Efficiency (RE) of this system was found around 89.7% and 97.6%, respectively. In addition, NMR spectra revealed the presence of flavonoids O-glycosylated (quercitrin and myricitrin) which might be related to the antiglycant and antioxidant activities. The YP presented larger content of quercitrin (117.6 ± 0.4 mg per each 100 g of fresh fruit). Therefore, pedra-ume caá should be employed as an alternative nutraceutical source, as well as intherapeutic pourposes.
