Figure 1From: A validated stability-indicating TLC-densitometric method for the determination of stanozolol in pharmaceutical formulations HPTLC chromatogram of standard stanozolol (800 ng/spot) and acid treated (1N HCl, reflux for 2 hr at 80°C; 1000 ng/spot) after staining with phosphomolybdic acid (PMA), stanozolol peak has R f = 0.46 ± 0.02 (a) and degradant has R f = 0.55 (b): mobile phase; petroleum ether: acetone (6:4, v/v).
