Embodiment 1

[0012] The freshly collected paulownia flower medicinal materials are cleaned, washed with water to remove the sediment, and squeezed with a press to extract the juice while it is fresh. Add 3 times the amount of tap water to the obtained dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned 3 concoctions were combined and filtered with a 100-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 65°C. When the relative density of the concentrated extract was 1.15, the extract was frozen in a -80°C refrigerator for 6 hours. Take out the east knot, freeze-dry, the pressure is 0.09Mpa, the temperature is -20 ℃, dry for 24 hours. Take out the freeze-dried product, crush it at low temperature, pass through an 80-mesh sieve, the moisture content is not higher than 12%, pack it into a bag, 1kg / bag, add...

Embodiment 2

[0014] The freshly collected paulownia flower medicinal materials are cleaned, washed with water to remove the sediment, and squeezed with a press to extract the juice while it is fresh. Add 5 times the amount of tap water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract the juice. The remaining medicinal dregs are squeezed with a press to extract the juice. The above-mentioned 3 concoctions were combined and filtered with an 80-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 70 °C. When the relative density of the concentrated extract was 1.10, the extract was frozen in a -80°C refrigerator for 8 hours. Take out the east knot, freeze-dry, the pressure is 0.08Mpa, the temperature is -40 ℃, dry for 48 hours. Take out the freeze-dried product, crush it at low temperature, pass through a 60-mesh sieve, the moisture content is not higher than 12%, bag it, 1kg / bag, add the bagged ...

Abstract

The invention discloses a freshly-squeezed paulownia flower freeze-dried powdery decoction piece and a preparation technology thereof. The preparation technology comprises the following steps: after the paulownia flowers are harvested, picking qualified paulownia flowers, washing selected paulownia flowers, squeezing the fresh paulownia flowers, filtering the juice, adding water into the residues, filtering, squeezing; merging the juice, carrying out reduced pressured concentration, freeze-drying the liquid, collecting the freeze-drying products, grinding the obtained solids, and packaging the powder into vacuum bags. The provided preparation method maximally preserves the polar and non-polar effective components in paulownia flowers. The decoction piece is convenient for transportation, storage, and blending, the quality is controllable, and the curative effect is reliable. The preparation technology has an important meaning for ensuring the clinical curative effect of traditional Chinese medicine. The provided decoction piece can generate prominent social benefits and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing traditional Chinese medicinal materials, and in particular relates to a processing technology of decoction pieces of paulownia flower of traditional Chinese medicine. Background technique [0002] The traditional Chinese medicine Paulownia Paulowniatomentosa (Thunb.) Steud.'s flower. This taste is bitter and cold, and has the effect of clearing away heat and detoxification. It is mainly used for the treatment of cough due to lung heat, bacillary dysentery, and bronchitis. [0003] The commonly used processing method of paulownia flower decoction pieces is: harvest when the flowers bloom in summer, dry, and pack for storage and transportation. Such decoction pieces are bulky, have poor hygienic indicators, are prone to pollution and mildew, and are difficult to guarantee quality, which is not conducive to formula adjustment and clinical efficacy, and even brings hidden harm to patients. [0004] At pre...
