Abstract:
OBJECTIVE: To compare TLC fingerprints between different batches of compound Herba taraxaci enemas (CHTE) ant to lay a foundation for establishing a more stable preparation technics and quality standards for CHTE. METHODS: The chloroform extract of 2 batches of CHTE were chromatographed by TLC and the samples were scanned by TLC scanner at a single wavelength of 280nm,the difference between different batches was compared. RESULTS: The TLC of chloroform extracts was well-separated,there were 6 common peaks and 2 non-common peaks in the TLC of 2 batches of samples, with some of the peaks identified in terms of the medicinal material categories, but there was a significant difference in contents among the common peaks. CONCLUSIONS: It was hard to guarantee the relative conformity in numbers of components and the contents between different batches of preparations,the preparation technics and quality standard of raw materials remain to be further optimized and the quality standard for Chinese herb medicinal preparations in hospital should be improved further.
