Nine phenolic compounds were metabolized by the soft rot fungus Lecythophora hoffmannii via protocatechuic acid and subsequently cleaved by protocatechuate 3,4-dioxygenase as determined by oxygen uptake, substrate depletion, and ring cleavage analysis. Catechol was metabolized by catechol 1,2-dioxygenase. Fungal utilization of these aromatic compounds may be important in the metabolism of wood ...

The influence of addition 2,4,6,8, and 10 microM of benzoic and cinnamic acids and selected phenolic acids (salicylic, p-hydroxybenzoic, gentisic, protocatechuic, vanillic, syringic, o-coumaric, p-coumaric, caffeic, ferulic, sinapic) on the activity of pancreatic lipase was examined in vitro. The strongest inhibition activities were observed with caffeic, ferulic and benzoic acid, while sinapic...

The enzyme, pyrocatechase, isolated and partially purified from anthranilate-adapted cells of a pseudomonad, was shown to catalyze the oxidative cleavage of the aromatic ring of catechol to cis, cis-muconic acid (1). Subsequently, through the use of 0218 and HsO~~, the two oxygen atoms incorporated across the double bond between the two hydroxyl groups were shown to be derived from atmospheric ...

Nardostachys jatamansi DC. and Selinum vaginatum (Edgew) Cl. are two endemic high altitude Indian medicinal plants that have been traditionally known as "Jatamansi" and "Bhootkeshi," respectively. These are used in various traditional herbal formulations and nutraceuticals, as well as to treat neurological disorders like epilepsy, hysteria, syncope, convulsions, and mental weakness. They resemb...
