An attempt has been made to assess the α-amylase inhibitory activity of a phytochemical compound extracted and purified from the leaf extract of . The total yield of the crude leaf extract was 11.42% and among the different solvents involved in this study, hexane and ethyl acetate at 7:3 was effective in the separation of phytochemical compounds. Hexane and ethyl acetate at 25:75% ratios (elution S4) were found greater in inhibiting α-amylase enzyme (83%). The most abundant compound found was Phytol (3,7,11,15-tetramethyl-2-hexadecen-1-ol) and its derivatives. It resulted that the binding energy for acarbose and phytol were -8.1 kcal/mol and -5.9 kcal/mol respectively. However, the binding affinity was greater in the case of acarbose than phytol and the binding sites are different for both the ligands. Therefore, this study adds scientific evidence of the α-amylase inhibitory activity of phytol derived from the leaf extract of .

α-Terpineol and 1,8-cineole are two important compounds in essential oils. This study developed an efficient method to recover α-terpineol from model oil (MO) based on association extraction by in situ formations of deep eutectic solvent (DES) between α-terpineol and some quaternary ammonium salts (QASs) by hydrogen-bond (HB) interaction. Such interaction could be broken almost completely by the introduction of water, due to the stronger HB interaction between water and QASs, which could release α-terpineol by liquid-liquid separation and save the organic solvents consumption.

Wheat viruses are major yield-reducing factors, with mixed infections causing substantial economic losses. Determining field virus populations is crucial for effective management and developing virus-resistant cultivars. This study utilized the high-throughput Oxford Nanopore sequencing technique (ONT) to characterize wheat viral populations in major wheat-growing counties of Kansas from 2019 to 2021.
