Problems solved by technology

The preparation process of granular decoction pieces, the extraction is not only time-consuming and energy-consuming, but also because a large amount of water is often used as a solvent, it is difficult to extract the non-polar active ingredients in the medicinal materials
In addition, since the paulownia flower medicinal material used for extraction is also dried and stored for a long time, the loss of active ingredients is also great

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 drinking water to the obtained dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract 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 is 1.15, transfer it to a vacuum drying oven, dry at 60°C for 8 hours, pass through a 60-mesh sieve after crushing, pack into bags, 1kg / bag, add antioxidants and desiccants in bags, and vacuum seal That's it.

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 drinking water to the obtained dregs, stir for 30 minutes, and press with a plate-and-frame filter press to extract 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 is 1.10, transfer it to a vacuum drying oven, dry at 65°C for 6 hours, pass through a 60-mesh sieve after crushing, pack into bags, 1kg / bag, add antioxidants and desiccants in bags, and vacuum seal That's it.

Abstract

The invention discloses a freshly-squeezed paulownia flower vacuum-dried powdery decoction piece and a preparation method 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, drying the liquid in vacuum, grinding the obtained solid, 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...
