J. Liq. Chrom. Rel. Technol. 27, 2087-2100 (2004). HPTLC of tetrandrine on silica gel with toluene - ethyl acetate - methanol - 28 % ammonia 100:100:50:3. Detection under UV light at 366 nm, and under white light after reaction with iodine (yellowish zones). If the plate is subsequently derivatized with anisaldehyde solution, the alkaloids show a strong blue fluorescence under UV light at 366 nm. Quantitative determination at 210 nm. The calibration curve is linear for 50 - 112.5 ng tetrandine per zone.
