The toxicity of the contaminated powder contributed to toxic aflatoxins has been well-known in the literature. However, before this study, the specific fungal strain behind aflatoxin production remained unidentified. Our research aimed to isolate and identify fungi from the tainted sandwiches while also assessing the preservation of sandwiches in ambient conditions.

This comprised one novel component, ecurvoside, and six well-studied compounds, namely astragalin, isoquercitrin, nicotiflorin, rutin, hesperidin, and neohesperidin. The chemical structures of compounds were identified using spectroscopic techniques and a comparison with previously published studies.

The inhibitory capability of active compounds in the from Thua Thien Hue, Vietnam over the Angiotensin-Converting Enzyme 2 (ACE2) protein in human body - the host receptor for SARS-CoV-2 and the main protease (PDB6LU7) of the SARS-CoV-2 using docking simulation has been studied herein. The results indicate that the ACE2 and PDB6LU7 proteins were strongly inhibited by 10 out of 24 compounds accounting for 70.

Samples of chicken and pig muscles previously dosed with OTC residues were subjected to boiling or microwave treatment, and the residues were extracted in a mixture of citrate buffer-MeOH (75:25 v/v), and then analyzed by high performance liquid chromatography with photodiode array detection using a XBridgeTM C18 reverse-phase chromatographic column. Thermal treatment resulted in the degradation of OTC and the concentrations of the degradation products α-apo-oxytetracycline (α-apo-OTC) and β-apo-oxytetracycline (β-apo-OTC) in muscle samples amounted to 0.
