Efficient Synthesis of Apigenin
An efficient synthesis of apigenin using 1,3,5-trimethoxybenzene and anisaldehyde as starting materials is described, involving Friedel–Crafts acylation, selective demethylation, cyclisation, and demethylation. This transformation features a new method for the deprotection of methyl ethers. The overall yields reached approximately 55%.

Camomile autofermentation in polyethylene glycol/dextran two-phase system [PDF]
The objective of this study was the investigation of the extractive bioconversion of apigenin-7-O-β-glucoside in camomile ligulate flowers into apigenin by autofermentation in polyethylene glycol 6000/dextran 200000 two-phase system.

An efficient method for the synthesis of apigenin (4’,5,7-trihydroxyflavone, a traditional medicine) from phloroglucinol and anisaldehyde has been developed. This transformation features a green method for hydroxyl protection as methyl ethers and a different way for cyclisation using iodine in DMSO. The overall yield of 40% is satisfactory.

Introduction: CD26/dipeptidyl peptidase IV (DPP4) is a cell-surface glycoprotein present on most epithelial cells that modulates the local response to external signals. We have previously shown that the dietary flavone apigenin (4′,5,7-trihydroxyflavone)

Oral leukoplakia, which presents as white lesions in the oral cavity, including on the tongue, is precancerous in nature. Conservative treatment is preferable, since surgical removal can markedly reduce the patient’s quality of life. In the present study,

The authors employed widely targeted metabolomics, microbial amplicon sequencing, and fermentation assays to investigate the microbiome 's influence on PCRC 's (pericarp of Citrus reticulata ' Chachi ') flavonoid profile over 0–19 years of storage. Based on the correlation analysis, solid‐state and liquid‐state fermentation, and catalytic activity ...
