TITLE:
摘要: 目的:筛选板蓝根饮片产地加工炮制技术,为保证板蓝根饮片质量提供依据。方法:对新鲜采收的板蓝根药材在4种不同干燥程度下切制后所得饮片[A.切片后60 ℃干燥;B.切片后自然干燥;C.自然干燥(13~15 d)后切片,再60 ℃干燥;D.自然干燥(30~50 d)后切片,再60 ℃干燥],从外观评分及水分、灰分、浸出物、主要成分(R,S)-告依春的含量方面进行比较。结果:各饮片外观性状评分从高到低为C>D>A>B,水分从高到低为B>A>D>C;灰分各法差别不大;浸出物和(R,S)-告依春含量从高到低均为C>A>B>D。结论:4种加工炮制技术所得板蓝根饮片质量不同,将鲜品自然干燥(约15 d)到一定程度后再切制及干燥后所得板蓝根饮片的质量相对最好。
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.
