Psoralen and angelicin are organic, natural chemical compounds, belonging to the furanocoumarin group, which are quite common in nature. Among others, these compounds are present in plants of the celery, rutaceae, mulberry and bean families, such as celery, carrot, lemon and fig. Interestingly, they exhibit a variety of biological activities, for instance insecticidal, anticonvulsant, anticancer, and antioxidant properties. For this reason, they are commonly used in different area of life. For example, psoralen is used in photochemotherapy as a photosensitizer in the treatment of psoriasis or acquired vitiligo (PUVA therapy). However, there is evidence that overexposure to psoralen and angelicin can also cause adverse effects. For these reasons, a number of analytical methods have been developed for their determination in environmental samples, while the vast majority of them are based on separation techniques. This paper discusses issues related to psoralen and angelicin and their analytics.

A quantitative method using precoated silica gel-60 Lichrosphere high-performance thin-layer chromatography (HPTLC) plates, automated band wise sample application, and n-hexane:acetone:formic acid (2:1:0.025 υ/υ/υ) as mobile phase, has been developed and validated for the analysis of psoralen in marketed formulations and novel solid lipid nanoparticles (SLNs). Densitometric analysis was performed at 250 nm in absorbance mode. Compact bands of psoralen were obtained at Rf 0.32 ± 0.02. The method was validated for linearity, precision, robustness, sensitivity, specificity, and recovery. Linearity (r2 = 0.995), limit of detection (8.0 ng band-1), limit of quantification (18.1 ng band) -1, recovery (98.06–99.64%), and precision (≤0.74) were satisfactory. Statistical analysis established that the developed method for quantification of psoralen in marketed formulation and from solid lipid nanoparticles is reproducible and selective.
