ABSTRACT
AIM:To determine the content of the trace arsenic and mercury in Fructus Mume and Fructus Mume charcoal. METHODS:Atomic fluorescence spectrometry was used. RESULTS:The content of arsenic in Fructus Mume is 0.0597～1.0001 mg?g -1, that of mercury is 0.0198～0.0300 mg?g -1. CONCLUSION:This method is simple to handle, the quantitative analysis is accurate.
ABSTRACT
AIM: To study the DNA fingerprinting of crude and processed Atractylodes lancea. METHODS: DNA fingerprinting of samples of crude and processed Atractylodes lancea were examined by RAPD. RESULTS: All crude Atractylodes lancea showed similar fingerprinting characteristics,while the processed Atractylodes lancea products indicated considerable different results. CONCLUSION: DNA fingerprinting is a reliable method for di-(fferentiating) crude Atractylodes lancea.
