Synephrine – A potential biomarker for orange honey authenticity [PDF]

Food Chemistry, 2017
A LC-MS/MS method for synephrine as a biomarker for orange honey authenticity was developed and validated. The sample was extracted with 5% TCA and cleaned up with Florisil providing 83.7% recoveries. Ions transitions for quantification and identification were 168→135.0 and 168→107.0, respectively.

Synephrine as a Specific Marker for Orange Consumption

Journal of Agricultural and Food Chemistry, 2017
To validate the suitability of synephrine, known to be a highly abundant alkaloid in oranges, as a dietary biomarker for orange consumption, a highly sensitive and robust stable isotope dilution analysis (SIDA) as well as an ECHO method, using the analyte itself as a pseudointernal standard injected into the analysis run to provide an "echo peak" of ...

Theoretical spectroscopic signature of synephrine using DFT and the effect of hydrogen removal

Phase Transitions, 2022
The present work deals with the vibrational spectroscopic signature of the synephrine molecule and its radical in the gas phase. We have optimized synephrine and synephrine- in the ground state.

Review of Case Reports on Adverse Events Related to Pre-workout Supplements Containing Synephrine [PDF]

Cardiovascular Toxicology, 2023
The use of pre-workout supplements has become increasingly popular, including the use of supplements containing synephrine. Synephrine might stimulate weight loss and improve sports performance by its proposed adrenergic properties.

Stereochemical and pharmacological differences between naturally occurring p-synephrine and synthetic p-synephrine

Journal of Functional Foods, 2012
p-Synephrine, the primary protoalkaloid in Citrus aurantium (bitter orange) and some other Citrus species, exists in nature in the l- or [R-(−)]-enantiomeric form, whereas synthetic p-synephrine is a racemic mixture of the l- and d-enantiomeric forms.

Determination of Synephrine Enantiomers in Food and Conjugated Synephrine in Urine by High-Performance Liquid Chromatography with Electrochemical Detection

Analytical Biochemistry, 1996
Determination of synephrine enantiomers was made with HPLC with electrochemical detection using a chiral ligand-exchange column (Sumichiral OA-6000). The calibration curve for each enantiomer showed good linearity (r = 0.999) at 1.0-500 pmol injected with a detection limit of 1.0 pmol (signal-to-noise ratio (S/N) = 3). Relative standard deviation (RSD)
