TLDR The method effectively measures spermidine in hair lotions.
The study focused on developing a capillary gas chromatographic method to quantitatively determine spermidine (SPD) in hair lotions. Spermidine, a biogenic polyamine, was noted for its role in promoting hair growth. The method involved using 1,6-diaminohexane as an internal standard, a methyl silicone capillary column, and a flame ionization detector. Hair lotion samples were treated with an alkaline solution, extracted with diethyl ether containing ethyl chloroformate, and analyzed. The method was validated for specificity, linearity, precision, and accuracy, confirming its effectiveness for measuring SPD in hair lotions.
