| titleOfInvention | A kind of preparation method of campanulaceae general flavone |
| abstract | The invention discloses a kind of extracting methods of campanulaceae general flavone, this method comprises the following steps that: commercially available fresh campanulaceae being cleaned, slice, drying, grinding and sieving, take 80 mesh oversize under 60 meshes, the ethyl alcohol that volume fraction is 70~75%, 70 DEG C of 3~4h of extraction on thermostat water bath is added by solid-liquid ratio 1: 25~30.Leaching liquor is collected, filtrate is concentrated in filtering, removes fat using Soxhlet extraction method.Purified with macroreticular resin, repeat the above steps enriching and purifying object, then uses ethyl acetate backflow 4h, obtains finished product after concentration, dry, crushing.The present invention has the advantages that at low cost, impurity content is few, production process no pollution to the environment after realizing compared with prior art. |
