Abstract��
OBJECTIVE: To estiblish quality control method for Liuwei Muxiang capsule. METHODS: Its ingredients,geniposide,Radix Aucklandiae,Flos Rhododendri Mollis,Fructus Piperis Longi,were identified by TLC.A thin-layer densitometry for determining geniposide,the main effective component from Fructus Gardeniae in the capsule was investigated. RESULTS: The identified characteristics of the chromatography were distinct and easily distinguished;The determining method was linear over the range of 15g with the average recovery 95.3% and the RSD 4.8% ��-sitosterol and rhodojaponin-��,were isolated from the flowers of Rhododendron molle G.Don (Flos Rhododendri Mollis) for the first time. CONCLUSION:BZThe quality standard of the capsule was provided.The method for identification and determination is simple,reproducible and practical.The rhodojaponin-�� from the flowers and the rhometoxin from the fruits are the same compound.Its content of the flowers is 0.3 g��g-1 only,much lower than that of the fruits.
