 Chemical Identification,TLC:

 1. Powder (60 mesh) 50 mg, 10 ml methanol soaking overnight, ultrasonic oscillation 30 minutes, will be concentrated extract of 1 ml for the sample used. Another glycosides from the leaves madder C, madder glycosides, large-Madder glycosides B, a large-Madder glycosides as reference substance. Separate kind in the silica gel G plate, ethyl acetate - methanol - formic acid (4:1:0.1, and water saturation), the sunlight with yellow or orange spots. Ammonia vapor smoked, the red dot significantly. (Check anthraquinone glycosides)

 2. Powder (60 mesh) 100 mg, 10 ml methanol soaking overnight, ultrasonic oscillation 30 minutes, extracts slightly condensed, through small silica gel column, petroleum ether - ethyl acetate (4:1) cleared a free anthraquinones quinone composition, concentration to 1 ml for the sample used. Another take-hydroxy madder, madder of the reference substance. Points respectively in the silica-6 plate with benzene - of ethyl - methanol - formic acid (3:1:0.2:0.1, and water saturation).Purpurin color orange,Alizarin color purple red.
