Identification : 1.To 0.5g of the powder add 10 ml of water, shake vigorously, a persistent foam is produced.2.To 0.5g of the powder add 20 ml of methanol, heat at 80ºC under reflux for 1 hour, cool down and filter. Evaporate the filtrate to about 5 ml and used it as the test solution. Dissolve saikosaponin, a saikoponin in methanol to produce a solution containing each of 0.5 mg per ml as the reference solution. Carry out the method for thin layer chromatography (Appendix Vl B), using silica gel G as the coating substance and ethyl acetate-ethanol-water (8;2:1) as the mobile phase. Apply separately to the plate 5µl of each of the two solutions. After developing and removal of the plate, dry it in the air, spray with 5% solution of dimethylaminobenzaldehyde in 40% sulfuric acid, heat at 60ºC until the spots appear. Examine under sunlight and ultra violet light (365 nm) separately. The spots or the yellow fluorescent spot in the chromatogram obtained with the test solution correspond in position and colour to the spot in the chromatogram obtained with the reference solution.Total ash: Not more than 8.0% (Appendix lX K)Extractives: Carry out the hot extractions method described under the determination of ethanol-soluble extractive (Appendix X A), using ethanol as solvent, not less then 11.0%
