Abstract:
Objective To establish the quality standard for Tibetan medicine MNXT granule.Methods Inula racemosa,Tinospora sinensis were identified by TLC; Isoalantolactone and alantolactone were determined by HPLC.Results Inula racemosa,Tinospora sinensis could be identified by TLC.The concentration of isoalantolactone was linear in the range of 0.281～0.842 μg,r=0.9998,with the average recovery rate being 98.5％,RSD being1.14％.The concentration of alantolactone was linear in the range of 0.232～0.696 μg,r=0.9999,with the average recovery rate being 97.4％,RSD being 1.10％.Conclusion The method was simple,accurate,repeatable and able to control the quality of preparation effectively.
