NOVELTY - Separation and enrichment of total flavone and total alkaloid of lotus plumule comprises heating, reflowing and extracting lotus plumule by 50-80 mass% ethanol; filtering to obtain extracted lotus plumule liquid; decompressing and concentrating until mass is 3-5 times of raw drug mass; adsorbing and clearing extracted liquid; filtering to obtain liquid; performing ion exchange using macropore weak acid cation exchange resin on liquid; eluting with pure water to remove foreign matters; and separating total flavone using 50-95 mass% ethanol as eluting agent.    USE - Separation and enrichment of total flavone and total alkaloid of lotus plumule.    ADVANTAGE - The method is simple and easy to carry out. It has low cost and environment friendly. It produces high yields of total flavone and total alkaloid of lotus plumule.    DETAILED DESCRIPTION - Separation and enrichment of total flavone and total alkaloid of lotus plumule comprises heating, reflowing and extracting lotus plumule by 50-80 mass% ethanol at amount of 6-12 times by mass of raw drug, in which extraction is performed for 1-3 times; filtering to obtain extracted lotus plumule liquid; decompressing and concentrating until mass is 3-5 times of raw drug mass; adsorbing and clearing extracted liquid; filtering to obtain liquid without foreign matters; performing ion exchange using macropore weak acid cation exchange resin on liquid without foreign matters; eluting with pure water to remove foreign matters and taking 50-95 mass% ethanol as eluting agent to separate total flavone; concentrating and drying eluted liquid to obtain enriched substance of total flavone; taking 50-95 mass% ethanol containing sodium chloride (NaCl) as alkaloid eluting agent; separating total alkaloid; concentrating eluting liquid to dry it; washing with hot ethanol for several times to remove NaCl; combining washing liquid; refrigerating; filtering; recovering ethanol; and drying to obtain enriched component of total alkaloid.
