Embodiment 1
[0019] (1) Weigh 50kg of Andrographis paniculata, put it into 400kg of purified water and decoct, keep boiling for 90 minutes, and filter. Add 300kg of purified water to the filtered medicinal dregs, decoct for the second time, keep boiling for 90 minutes, and filter. The combined two decoctions were concentrated to 50 L, added 100 kg of 95% ethanol, stirred evenly, precipitated for 24 hours, filtered, and collected the filtrate. Recover the ethanol in the filtrate until the filtrate has no alcohol smell, then concentrate the filtrate after recovering ethanol to 30L.
