      J. Anhui Med. & Pharm. 17 (2), 202-203 (2013). Banlangen granule, processed of Radix Isatidis, is a traditional Chinese herbal medicine prescribed clinically to treat sore throat, cheek swelling, acute and chronic tonsillitis and mumps. For quality control a method for the determination of leucine, a main antiviral effective component, is presented. TLC on silica gel with n-butanol – glacial acetic acid – water 19:5:5, detection by spraying with 0.1 % ninhydrin in acetone, heating at 105 °C and viewing in daylight. Quantification by densitometry at 509 nm. Validation of the method by investigation of the linearity range (0.10-0.90 µg/zone, r = 0.998, n=5), precision (%RSD = 2.8 %, n=6), stability (%RSD = 0.8 %, n=6, towards single lane within one hour), and reproducibility (%RSD = 2.0 %, n=6, within plate). The recovery (by standard addition) was 98.8 % (%RSD = 1.1 %, n=6).
