[Analysis and characterization of fingerprint infrared spectra for ecology-planted Coptis chinensis].

The fingerprint features of infrared spectra for Coptis chinensis in different shading conditions (shelf, firry wood, corn wood) and with different ages (one year to five years) were studied. According to the ratio of characteristic peaks, the rules of the influence of shadings and ages on Coptis chinensis growth were illustrated, which confirms the feasibility of ecological planting technique for Coptis chinensis. Fourier transform infrared (FTIR) spectroscopy was used to analyze the influence of growing conditions on the growth of Coptis chinensis.

[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.
