| Abstract: | The acid-heating extraction conditions of LPC from fresh leaves of Stellaria media were optimized in this study. The effects of solid-liquid ratio, layer number of filter cloth, temperature and time on extraction rate of LPC were investigated. Based on the results of single factor tests, orthogonal test was designed to optimize the extraction conditions of LPC. The results showed that the optimal extraction conditions are as follows: solid-liquid ratio 1:5, layer number of filter cloth 5 and heating temperature 75 ℃ and heating time 11 min. Under these conditions, the extraction rate of LPC reaches 52.08% and the yield rate is 27.17%. |
