Application

Indole-3-butyric acid (IBA) has been used as a standard to monitor IBA in urine samples by tandem mass spectrometry-selected reaction monitoring (SRM) and Ultra-high performance liquid chromatography (UHPLC)[1], as a standard for high performance liquid chromatography (HPLC) for the quantification of IBA in foliar tissues of Coffea canephora seedlings[2].

Biochem/physiol Actions

Indole-3-butyric acid (IBA) is a naturally occurring phytohormone auxin (plant growth regulator). It promotes root formation in cuttings but does not affect ethylene levels. IBA might be a precursor for indole-3-acetic acid (IAA) through β oxidation pathway. IBA is present in plant species like Zea mays, Pisum sativum and Arabidopsis. IBA is more potent than IAA for inducing root formation.[3]

    Abscisic acid (ABA) is a ubiquitous phytohormone involved in many developmental processes and stress responses of plants. ABA moves within the plant, and intracellular receptors for ABA have been recently identified; however, no ABA transporter has been described to date.

    While over 10% of the human metabolome is directly associated with the gut microbial metabolism, specific metabolites are largely uncharacterized. Therefore, methods for the identification and quantification of microbiota-associated metabolites in biological fluids such as urine or plasma are necessary
