Sustainable Iron Catalysis for Chemodivergent Oxidation of Lignin‐Based Vanillyl Alcohol: Selective Access to Vanillin and Vanillic Acid

European Journal of Organic Chemistry, EarlyView.
Green reaction media enable chemodivergent oxidation of vanillyl alcohol, selectively affording vanillin or its fully oxidized counterpart, vanillic acid. The use of an earth‐abundant, inexpensive, and nontoxic iron catalyst for the transformation of lignin‐derived alcohol to fine chemicals underscores the sustainability of the process. A low E‐factor (

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

Food Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Determination of Vanillin and Ethyl Vanillin by Gas-Liquid Chromatography

Journal of AOAC INTERNATIONAL, 1964
Abstract A rapid method has been developed in which gas-liquid chromatography is used to separate vanillin and ethyl vanillin in vanilla samples and determine them quantitatively. A flame ionization detector is used for the vanillin determination. 2-Phenoxyethanol is used as internal standard.
