CBS 107, 11-12 (2011) HPTLC of tiliroside (a cosmetic active obtained by extraction from a plant of the family Sterculiaceae) and side components kaempferol-3-glucoside, kaempferol-3-rutinoside, kaempferol, and coumaric acid on silica gel with ethyl acetate - formic acid - acetic acid- water 100:11:11:27 + 1% heptane. Detection under UV 366 nm after spraying with natural products reagent (1 % diphenylborinic acid 2-aminoethylester in methanol) and under white light after spraying with anisaldehyde sulfuric acid reagent (0.5 mL anisaldehyde in 85 mL methanol with 10 mL acetic acid and 8 mL conc. sulfuric acid) and heating at 90-125 °C for 15 min. Quantitative absorption measurement of tiliroside at 315 nm using a 4-point calibration via peak area. The tiliroside contents in the sample extracts were determined as: 1 = 1.09 µg (RSD = 0.4 %), 2 = 0.93 µg (RSD = 0.8 %), 3 = 1.19 µg (RSD = 1.2 %) and 4 = 3.32 µg (RSD = 0.3 %). During the side component analysis no kaempferol, coumaric acid, and glucose were detected in the tiliroside samples. Small amounts of kaempferol-3-glucoside and kaempferol-3-rutinoside were found. HPTLC covers several tasks: quantification of the active ingredient in a complex plant matrix for determining the quality of the raw material, in-process control for monitoring the impurity profile during the manufacturing process and the quantification of the active ingredient in the final product.
