OBJECTIVETo evaluate the quality difference between Coptis chinensis planted with ecological techniques and shelf planted Coptis chinensis.

METHODSUltraviolet-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.

RESULTSThe 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.

CONCLUSIONThe 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.
