摘 要:比較鹽杜仲不同溫度下炮制前后主要化學(xué)成分松脂醇二葡萄糖苷的變化,推測其適宜炮制溫度并優(yōu)化炮制工藝參數。依據《中華人民共和國藥典》(2020年版)中的“斷絲”指標,考察不同炮制溫度對杜仲“斷絲”程度的影響,優(yōu)化杜仲炮制工藝參數。采用高效液相色譜(HPLC)分析杜仲生品和鹽炙品主要化學(xué)成分的差異,研究炮制工藝對杜仲質(zhì)量的影響。結合實(shí)驗數據確定杜仲炮制溫度為110 ℃,時(shí)間控制在8 min左右。高溫炮制后杜仲化學(xué)成分含量明顯降低,其主要有效成分松脂醇二葡萄糖苷(PDG)也大幅減少。采用HPLC方法,分析炮制前后杜仲主要化學(xué)成分的變化,為杜仲鹽炙工藝和鹽杜仲的質(zhì)量控制提供了更可行的參數依據。 |

Abstract:Based on the changes of the main chemical contents in pinoresinol diglucoside (PDG) before and after processing at different temperatures of Salt Eucommia the optimum processing parameters were determined. According to the "broken silk" index in "Pharmacopoeia of the People's Republic of China" (2020 edition), the effect of different processing temperatures on the degree of "broken silk" of Eucommia was investigated. Using High performance liquid chromatography (HPLC) to analyze the difference of main chemical contents between raw Eucommia ulmoides and salted products the effect of processing technology on the quality of Eucommia ulmoides was studied. Based on the experimental data it was determined that the optimum temperature for Eucommia ulmoides processing was 110 ℃, and the time was controlled at about 8 min. After high temperature processing, the contents of chemical components of Eucommia ulmoides was significantly reduced, and the main active ingredient pinoresinol diglucoside was also greatly reduced. |
Key words:Salt Eucommia; processing temperature; HPLC analysis; pinoresinol diglucoside |
