Summary: In this study, we assessed the morphological variation of Devaleraea mollis from the Northwest Pacific and found that it actually includes two species. The alga previously identified as 'Palmaria palmata' is now described as a new species, D. inkyuleei, which is morphologically similar to D. mollis but has a more southern range.

Summary: A separation process was developed to fractionate and recover three anti-inflammatory components from the red alga P. palmata, including sugars, phycobiliprotein, and chlorophyll. The process involved three steps without the use of organic solvents. The extracts obtained from each step, rich in sugars (E1), phycobiliprotein-derived peptides (E2), and chlorophyll-related components (E3), showed anti-inflammatory activity without any negative effects.

Summary: We report a rare larva of the family Bathysaurus mollis that was collected off the coast of New Caledonia on November 30, 2014. Larval stages of the family Bathysauridae are uncommon, and only 11 specimens have been reported for both species, including our own. Our larva is in exceptional condition, measuring 98.6 mm in standard length, which is on the larger side of the larval phase. Additionally, we summarize previous literature and provide commentary on the reduction of the maxilla in bathysaurids.

Summary: Propolis, a honeybee product, contains bioactive compounds with antioxidant, anti-inflammatory, anticancer, and antimicrobial effects. Studies have shown that representative polyphenols and extracts of propolis exhibit pharmacological effects by targeting similar pathways related to inflammation, proliferation, and antioxidant mechanisms.

Summary: Enhanced solvent extraction (ESE) and pressurized liquid extraction (PLE) were used for the first time to extract antioxidant compounds from Prestonia mollis leaves. PLE showed higher extraction yields and was more sensitive to operating conditions. The highest total phenolic content was obtained through ESE with a hydroalcoholic mixture at 100 bar and 75 C-degrees. The extract demonstrated potential suitability for the impregnation of polylactic acid (PLA) for biomedical applications.

Summary: This study optimized the extraction conditions of polyphenols, flavonoids, and chlorophyll from peppermint and common nettle leaves using green chemistry. The use of glycerol-water systems resulted in higher concentrations of these active compounds compared to traditional solvents like water and ethanol. Extraction temperature was found to significantly influence the concentration of the components in the extracts.

Summary: This study investigated the extraction and isolation of protein concentrates from different parts of coffee beans and analyzed their amino acid composition, caffeine content, protein nutritional quality, polyphenol content, and antioxidant activity. The results showed that coffee protein concentrates did not have high levels of branched-chain amino acids, but they had high levels of polyphenols and strong antioxidant activity.

Summary: Carrageenan, a polysaccharide derived from red algae, has significant economic potential in various industries. The most common source of carrageenan is Kappaphycus alvarezii, which is primarily farmed in Asian countries such as Indonesia, the Philippines, Vietnam, and Malaysia. Carrageenan extracted from K. alvarezii has received attention due to its economic potential and wide range of applications.

Summary: This study aimed to investigate the optimum conditions for ultrasonic-assisted pressurized liquid extraction of anthocyanins from Aronia melanocarpa pomace. Through optimization of pressure, temperature, ultrasound intensity, and solvent concentration, the total anthocyanin content extracted was increased by 19% at 80 degrees Celsius.

Summary: This study optimized the ultrasound-assisted extraction of bioactive compounds from Amaranthus hypochondriacus var. Nutrisol using response surface methodology. The results showed that temperature and ultrasonic power densities significantly affected the extraction of betalains, polyphenols, and other bioactive compounds. The optimal extraction conditions were found to be at 41.80 degrees C and 188.84 mW/mL.
