Fig. 1From: Luo Tong formula attenuates retinal inflammation in diabetic rats via inhibition of the p38MAPK/NF-κB pathwayChemical standardization of LTF by high performance liquid chromatography (HPLC) fingerprint analysis (254 nm and 210 nm). In the HPLC fingerprint at an absorbance of 254 nm, the peaks corresponding to Calycosin-7-O-β-d-glucoside (1); Notoginsenoside R1 (4); Ginsenoside Rb1(6); Aloe-emodin (7); Rhein (8); Emodin (9); Chrysophanol (10); Physcion and Tanshinone II A (11). In the HPLC fingerprint at an absorbance of 210 nm, the peaks corresponding to (2) Ginsenoside Rg1; (3) Salvianolic acid B and (5) Aloe-emodinBack to article page
