Figure 3From: Stress degradation studies and stability-indicating TLC-densitometric method of glycyrrhetic acid HPTLC Chromatogram (A) and UPLC chromatogram (B) of photo-degraded standard glycyrrhetic acid kept in sunlight for 24hr (1000 ng/spot): peak 1, degradant ( R f = 0.35 and R t = 1.687); peak 2, degradant ( R f = 0.38 and R t = 2.142); peak 3, glycyrrhetic acid ( R f = 0.42 and R t = 2.531); peak 4, degradant ( R f = 0.49 and R t = 2.916).
