This work describes a novel approach for the analysis of 11 phenolic compounds (naringenin, hesperetin, kaempferol, quercetin, epicatechin, epicatechin gallate, epigallocatechin gallate, genistein, daidzein, caffeic acid, gallic acid) in human milk. Clean-up of the sample and extraction of 11 analytes from milk was performed by dispersive liquid-liquid microextraction (DLLME). Under the optimal conditions, the extraction recoveries of 11 analytes were in a range from 94.3% to 108%. For determination of phenolic compounds in extracts, LC-ESI-MS/MS method was used. The calibration curves showed linearity in the concentration ranges from 0.01 to 1500 ng mL and the limits of detection were in a range from 0.18 ng L to 74 ng mL. The repeatability and intermediate precision expressed as the relative standard deviations were below 7.6% and 9.9%, respectively. The DLLME-LC-ESI-MS/MS method was successfully applied to the determination of phenolic compounds present in breast milk.

Objective: To detect phenolic acid compounds in various fruits and explore the differences in phenolic acids among different types of fruits.
Methods: The collected 75 types of fruits were classified into 6 categories: citrus、melon、drupe、berry、tropical fruit and pome fruits. The phenolic acid compounds were detected by high performance liquid chromatography-mass spectrometry.

Abnormal proliferation and migration of pulmonary artery smooth muscle cells (PASMCs) leading to pulmonary vascular remodeling are critical factors in the development of pulmonary hypertension (pH). Dehydrodiisoeugenol (DEH), a natural phenolic compound, is renowned for its antioxidant and anti-inflammatory properties. However, the precise role and mechanisms of DEH in PH remain unclear.

Stingless bee honey is a natural product consisting of sugars, organic acids, proteins, minerals, vitamins, phenolic compounds, and flavonoids. Due to its healing properties, honey is often used in phytotherapy and for homemade syrups. The search for natural therapeutic alternatives has been an increasing trend in recent years, mainly due to the side effects of artificial drugs and increasing antibiotic resistance.

Wound healing is a dynamic and complex process involving hemostasis, inflammation, fibroblast proliferation, and tissue remodeling. This process is highly susceptible to bacterial infection, which often leads to impaired and delayed wound repair. While antibiotic therapy remains the primary clinical approach for treating bacteria-infected wounds, its widespread use poses a significant risk of developing bacterial resistance.
