Selective determination of aloin in different matrices by HPTLC densitometry in fluorescence mode.
    Journal of pharmaceutical and biomedical analysis, 2011, Jan-25, Volume: 54, Issue:2

    A novel method based on the fluorescence excited solely on aloin by a H₃BO₃ derivatizing procedure, allowed its rapid and selective determination among the co-occurring components in a variety of complex matrices as several Aloes dried extracts and related commercial products. HPTLC LiChrospher silica gel 60 F254S, 20 cm x 10 cm, plates with ethyl formate: CH₃OH:H₂O (100:14.5:10, v/v) as the mobile phase were used. Densitometric determinations were performed in fluorescence mode, exciting wavelength 365 nm, optical filter K540 after derivatization with H₃BO₃. The method was validated giving rise to a dependable and high throughput procedure well suited to routine application. Aloin was quantified in the range of 110-330 ng with RSD of repeatability and intermediate precision not exceeding 2.3% and accuracy inside the acceptance limits.
