摘要: 采用微波辅助技术提取烟草多酚,利用高效液相色谱-光电二级管阵列检测器-质谱联用技术(HPLC-PDA-MS)对烟草多酚主要组分进行定性分析.研究了微波功率、甲醇用量、提取时间和料液比对烟草多酚得率的影响.经响应面优化确定烟草多酚的微波提取条件为:53%甲醇,料液比为1:11,微波功率为560W,提取时间为70s,在此条件下总多酚得率为22.38mg/g(干重).HPLC-PDA-MS测定表明,烟草多酚的主要组分为绿原酸和芸香苷.

Abstract:

In this paper, tobacco polyphenols were extracted through microwave-assisted technology, and their main components were identified by the combination of hgh-performance liquid chromatography, photodiode array detector and mass spectrography. Moreover, the effects of microwave power, methanol content, extraction time and material-to-liquid ratio on the polyphenols yield were investigated. It is seen from the response surface analysis (RSA) that, in the optimum extraction conditions for tobacco polyphenols, that is, With 53 % methanol as the solvent, a material-to-solvent ratio of 1:11, a microwave power of 560 W and an extraction time of 70 s, the yield of total to- bacco polyphenols reaches 22.38 mg/g (dry weight). HPLC-PDA-MS results demonstrate that the main components in tobacco polyphenols are chlorogenic acid and rutin.
