    • Abstract
  • A method of extraction and assay for the pectinesterase were investigated and proposed as follows: the best concentration of NaCl in extracting mixtrure is 5%,the best extracting temperature is 30℃,the best extracting time is 24 hours,the best conservating time is 24 hours,the best concentration of NaCl in mixture is 0.6% to 1.0%,and maintain the pH on 7.0.Between 30-50℃,the pectinesterase in achenes of Ficus awkeotsang has a good thermal stability.
