生态技术栽培黄连的质量评价

目的评价生态栽连与搭棚栽连的质量差异.方法选取经果林下、杉树林下,马桑林下、玉米套作、五倍子林下、厚朴林下、遮阳网下7种生态栽培与搭棚栽培的黄连样品,采用紫外-可见分光光度法、醇溶性浸出物测定法、水分及灰分测定法分别测定其总生物碱、醇浸出物、水分和灰分的含量.结果生态栽连中总生物碱及醇浸出物含量多数高于搭棚栽连;水分均小于12%,灰分均小于5%,二者含量均符合规定.结论生态栽连与搭棚栽连质量相当,技术成熟,方法可行,值得推广.

Quality assessment for Coptis chinensis planted with ecological techniques

OBJECTIVE: To evaluate the quality difference between Coptis chinensis planted with ecological techniques and shelf planted Coptis chinensis. METHODS: Ultraviolet-visible spectrophotometry, alcohol extract mensuration, moisture mensuration, and ash mensuration were used to determine the contents of total alkaloids, alcohol extract, water, and total ash of Coptis chinensis, which were planted in shelf, Rhus chinensis wood, M mulbery wood, corn wood, Magnolia officinalis wood, fruiter wood, shading net, and firry wood, respectively. RESULTS: The contents of total alkaloids and alcohol extract of Coptis chinensis Table planted with ecological techniques were higher than those of Coptis chinensis planted in shelf. The contents of water and total ash were less than 12% and 5%, respectively, which met the provisions of the pharmacopoeia. CONCLUSION: The quality of Coptis chinensis planted with ecological techniques is similar to that of Coptis chinensis planted in shelf. These ecological techniques for Coptis chinensis have become mature and practical.
