Abstract:
OBJECTIVE: To screen the habitat processing technology of Isatis tinctoria slices, and provide basis for its quality.METHODS: Appearance score, the contents of moisture, ash, extract and main component (R, S) -goitrin in I. tinctoria slices prepared by 4 kinds of dried degree [A. 60 ℃ drying after cutting; B. cutting after natural drying; C. cutting after natural drying (13-15 d), drying at 60 ℃ again; D. cutting after natural drying (30-50 d), drying at 60 ℃ again]from fresh harvested sample. RESULTS: Appearance score was in descending order with C>D>A>B; the content of moisture was in descending order with B>A>D>C. There was little difference in the content of ash among different methods. The contents of extract and (R, S)-goitrin were in descending order with C>A>B>D. CONCLUSIONS: The quality of I. tinctoria slices prepared by 4 processing technologies are different, and the quality of I. tinctoria slices prepared by cutting after natural drying (about 15 d)and drying at 60 ℃ again is relatively best.
