Optimization of salt-processing technology for Phyllanthus emblica by comprehensive score method / 中草药

ABSTRACT

Objective: To choose the optimal salt-processing technology for Phyllanthus emblica. Methods: Taking the contents of gallic acid, querectin, ethanol soluble extraction, and water-soluble extract as the indexes, the factors of brine concentration, watering multiple, soaking time, and drying temperature were investigated. L9(34) orthogonal design and comprehensive score were used to optimize the salt-processing technology for P. emblica. Results: The optimal salt-processing technology was: 3% salt, adding 1.2-fold water, soaking for 10 d, and drying under 90°C. Conclusion: The optimal salt-processing technology is stable, reasonable, and feasible, and could be used to guide the standardization production.
