ABSTRACT
In recent years, with the price rise of Amomum villosum, the quality of A. villosum in the market has been in disorder. To understand the quality status of A. villosum in the market and provide reference for the commercial size fifty-seven samples were collected from different producing areas or markets from August 2013. The samples were detected with evaluation on appearance quality, determination of the contents of bornyl acetate, determination of pesticide residues and heavy metals residues based on Chinese Pharmacopoeia 2015. The results showed that the pesticide residues and heavy metals residues met the requirments, all the samples from different producing areas were qualified except one sample from Fujian province. The qualified rate of native products and imports products samples from market were 43.75% and 14.29%, respectively, the qualified rate of the samples of Yunnan province from producing areas was higher than that from the market. There are two ports at the national level in Yunnan province, where the southern herbs from. A. villosumis one of import medicines from Southeast Asia, and lots of A. villosum samples import to China from Yunnan ports. Most of pharmacists believed that all of the samples from Yunnan province produced in Yunnan. The great majority of commercial species was A. villosum, but A. longiliglare was scarce. Through the survey, it isfound that the main factors affecting the quality of Amomi Fructus was source, lots of A. villosum samples have been replaced by the Amomi Fructus, so the source of imports Amomi Fructus was not clear, which was also more difficult to identify. The quality of A. villosum needs to protect, optimize germplasm, strict control of medicinal sources, specification for medicinal harvesting and processing technology.
