Abstract
The present disclosure provides a method for extracting(L.)R.Br., which includes the following steps: (1) the root tuber of(L.)R.Br. is soaked in water so that it can be fully infiltrated until having been taken as a sample, no white core is observed; (2) the root tuber of(L.)R.Br. is ultrafinely comminuted by wet method to obtain a dispersion slurry; (3) additional water is supplemented into the dispersion slurry to obtain diluted dispersion followed by heating and adding neutral protease, and then extraction is carried out through circulation and homogenization by the homogenization pump to obtain extracted material fluid; (4) heat preservation and enzyme inactivation; (5) coarse filtration to obtain a coarse filtrate; and (6) fine filtration to obtain a fine filtrate. The disclosure also provides a related extract of(L)R.Br.
