Barberry is a well known medicinal plant in Iran and has been widely used as food additive. The comprehensive survey of fungal contamination of barberry was undertaken in the market of Birjand, during March to June at 2012. Fungal infections of barberry were studied in thirty samples. Among these, Aspergillus spp., Penicillium spp. and Mucor spp. were major contaminants also the results showed that 57% of barberry was infected and most fungal species related to Aspergillus spp. and penicillium spp. Therefore it needs to undertake the management practices.展开更多

[Methods] Microscopic identification and thin layer identification were used to qualitatively identify barberry branches. Berberine content was determined by HPLC method, and the content of water, total ash, acid insoluble ash and extract was detected according to the method of the Chinese Pharmacopoeia (2020 edition). [Results] The microscopic identification showed that the features were obvious, and stone cells, cork cells, epidermal cells, stomata, fibers and catheter with reticulated pores could be found. Berberine was detected in barberry branches by thin layer chromatography, and the characteristic spots were separated clearly. Moisture, total ash, and acid insoluble ash content shall not exceed 13%, 6%, and 3%, respectively, and extract content shall not be less than 10%. Berberine hydrochloride (C_(20)H_(18)ClNO_(4)) should be calculated in the branches of Berberis wilsonae Hemsley and Berberis aggregata C. K. Schneid., and berberine (C_(20)H_(17)NO_(4)) content should not be less than 0.05%. The linear relationship was good in the range of 0.002-0.240 mg/mL ( R^(2)=0.999 5). The average recovery was 89.63%, and RSD was 5.28%. [Conclusions] The method was simple, accurate and reproducible, and can be used for the quality control of barberry branches.展开更多
