Department of Pathobiology and Biomedical Sciences, Muhammad Nawaz Sharif University of Agriculture, Multan, Pakistan/Ali-Ul-Murtaza Department of Rehabilitation Sciences, Muhammad Institute of Medical and Allied Sciences, Multan, Pakistan.

This study aimed to evaluate the efficacy of vinegar-soaked Ficus carica fruits (VSFCF) for managing cholelithiasis in adults. A parallel-group, single-blinded, randomized controlled trial at Noreen Nishat Welfare Hospital, Khanewal, Pakistan, was conducted from December 2023 to February 2024. Fifty adults with ultrasound-confirmed cholelithiasis were randomly assigned to receive either VSFCF (1 g/kg/day) or ursodiol (600 mg/day).

College of Pharmacy, Liaoning University of Traditional Chinese Medicine, Dalian, China/Province Multi-Component Chinese Medicine Engineering Technology Research Center of Liaoning, Dalian, China/Modern Traditional Chinese Medicine Research and Engineering Laboratory of Liaoning, Dalian, China.

Chebulagic acid and chebulinic acid are the two tannin compounds with the highest content in Terminalia chebula, they were separated by ODS column eluted with 20% methanol and 35% methanol, respectively. The compounds were identified by comparing the data of H NMR and C NMR with the literature; HPLC method was used to investigate the stable storage conditions of chebulagic acid and chebulinic acid; lipopolysaccharide (LPS) induced in vivo inflammation model and RAW264.7 macrophage in vitro inflammatory model to evaluate the anti-inflammatory activities of chebulagic acid and chebulinic acid.

The microbiota of cork and yellow stain as a model for a new route for the synthesis of chlorophenols and chloroanisoles from the microbial degradation of suberin and/or lignin.

Article Synopsis
  • Cork is primarily used for wine bottle stoppers, but it can contain 2,4,6-trichloroanisole, which causes a musty odor that negatively affects wine quality and leads to financial losses.
  • The presence of yellow stain in cork indicates a degradation linked to higher microbial populations, particularly filamentous fungi that break down lignin, and this microbiota contributes to the formation of chlorophenols and chloroanisoles.
  • Research identified specific fungal and bacterial species associated with yellow stain and demonstrated that certain strains can convert p-hydroxybenzoate into phenol, which can then be chlorinated, potentially leading to the development of 2,4,6-trichlorophenol.
