Tryptamine, β-phenylethylamine hydrochloride, putrescine dihydrochloride, cadaverine dihydrochloride, histamine dihydrochloride, tyramine hydrochloride, spermidine trihydrochloride, and spermine tetrahydrochloride (all Sigma-Aldrich) were used for standard solutions, and 1,7-diaminoheptane (Sigma-Aldrich) was applied for an internal standard. The concentrations of all standard solutions were adjusted to 0, 10, 50, 100, and 1000 ppm.

Stock standard solutions of BA, including tryptamine, β-phenylethylamine hydrochloride, putrescine dihydrochloride, cadaverine dihydrochloride, histamine dihydrochloride, tyramine hydrochloride, spermidine trihydrochloride, and spermine tetrahydrochloride (all from Sigma-Aldrich), were separately prepared at 10,000 mg/L concentration in deionized water. Working solutions at 1000 mg/L concentration were prepared by diluting 1 mL of each stock solution in deionized water to bring to a final volume of 10 mL. The concentrations of all standard solutions used were 0, 10, 50, 100, and 1000 mg/L. In addition, 1,7-diaminoheptane (Sigma-Aldrich) served as an internal standard.

BA analyses in Baechu kimchi samples and assay menstrua were conducted according to protocols described in a previous study [34 (link)]. For an internal standard, 1,7-Diaminoheptane (1 mg/mL; Sigma) was used. Tyramine hydrochloride, histamine dihydrochloride, cadaverine dihydrochloride, putrescine dihydrochloride, spermine tetrahydrochloride, spermidine trihydrochloride, tryptamine, and β-phenylethylamine hydrochloride were used to prepare standard solutions (all from Sigma). The analysis procedures included extraction of BAs, preparation of BA standard solutions, derivatization of BAs, and chromatographic separation of BAs. Both limits of detection and limits of quantification for all BAs were about 0.10 µg/mL in standard solutions and 0.01–0.10 mg/kg and 0.02–0.31 mg/kg, respectively, in food matrices [47 (link)].
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
