Quality tests were made on a Chinese medicine preparation “Unseiin” extract containing 8 crude drugs. The principal components were separated and determined by high performance liquid chromatography, gas chromatography and thin-layer chromatography-densitometry system. Composition of 6 commercial prescription products was as follows (in mg/g): ligustilide 0.01-1.30, paeoniflorin 0.10-4.63, berberine 1.25-4.35, palmatine 0.41-2.65, coptisine 0.36-2.29, woogonin 2.30-5.16, geniposide 1.53-6.12. The content variations among the products of manufacturer A in 4 different lots were comparatively small.
The stability of the extracts on storage was examined in use of several pakaging materials in hospital pharmacy. The extracts are highly hygroscopic, and a special attention should be paid to packaging materials, storage conditions and other factors.
