AI Article Synopsis
- Phenolic compounds significantly impact the quality of fruits and nuts, with almonds being particularly rich in these health beneficial compounds.
- The study aimed to optimize an extraction method to measure total polyphenols, flavonoids, and proanthocyanidins, while also assessing antioxidant capacity using HPLC for identification and quantification.
- Results indicated notable variations in antioxidant content among 11 Spanish almond genotypes, with the Belona, Guara, and Vialfas varieties showing the highest levels of beneficial compounds.
Article Abstract
Phenolic compounds have an important influence on fruit and nut quality. Almonds have been shown to be rich sources of phenolic compounds, which possess health-beneficial properties. The objectives of the study were to optimize an extraction method to determine the total amount of polyphenols, flavonoids and proanthocyanidins as well as the antioxidant capacity. In addition, the same extract was used for the identification and quantification of flavonoids by HPLC. The study was conducted on 11 Spanish almond genotypes. The results highlight the differences in the content of antioxidants, which add value to the quality of the fruit. It has been shown that genotype may strongly influence antioxidant capacity and total phenolic compounds. In this work, the almonds with higher results were (Belona, Guara and Vialfas) varieties.

Alzheimer's disease (AD) is a prevalent neurodegenerative disorder characterized by memory decline and cognitive impairments. The clinical treatments for AD have numerous adverse effects, hence the exploration of natural products for AD therapy is of significant importance. Protocatechuic acid (PA), a natural phenolic acid, has been shown to possess various pharmacological activities, including anti-inflammatory, antioxidant, and antitumor effects.

Obtaining gold nanorods (AuNRs) through biosynthesis is an alternative that replaces the traditional use of ascorbic acid with chemical compounds such as polyphenols, owing to their notable antioxidant properties. Therefore, we developed an AuNR biosynthesis method using an aqueous extract of sour guava (Psidium araca). Initially, a study was conducted to determine the antioxidant capacity of different parts of the fruit (pulp and peel) over 14 days.

Marine microbial communities colonizing the skin of invertebrates constitute the primary barrier between host and environment, potentially exerting beneficial, neutral, or detrimental effects on host fitness. To evaluate the potential contribution of epibiotic bacteria to the survival of early developmental stages of Octopus mimus, bacterial isolates were obtained from eggs, paralarvae, and adults. Their enzymatic activities were determined, and antibacterial properties were assessed against common marine pathogens.

The study addresses the utilization of food waste by-products from faba bean (Vicia faba L.) pods (FBP) as an alternative feed supplement to promote sustainable piglet growth by reducing antimicrobial use. Objectives include evaluation of FBP in terms of nutritional components (proximate composition, fibres, minerals), phytochemical composition (total phenols, HPLC-MS profiling), and in vitro biological activities.
