Problems solved by technology

Due to the time-consuming and energy-consuming extraction during the preparation of granule decoction pieces, and because 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 Patrinia herb used for extraction is also dried and stored for a long time, the loss of active ingredients is also great

Embodiment 1

[0012] Wash the freshly collected Patillaria herb, cut into 1cm-wide slices, add water 0.5 times the weight of the medicinal material, stir for 15 minutes, and squeeze the juice while it is fresh. Add 2 times the amount of tap water to the obtained medicinal dregs, stir for 20 minutes, and press with a plate-and-frame filter press to extract the juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above-mentioned 3 times of Patonia herb juice, filter through a 60-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 60°C. When the relative density of the concentrated extract was 1.10, it was transferred to a -20°C refrigerator and frozen for 12 hours. Freeze drying was carried out after taking out the frozen material, the temperature was set at -18°C, the pressure was 0.09Mpa, and the time was 24 hours. Collect the freeze-dried product, pulverize it, pass through a 60-mesh sieve,...

Embodiment 2

[0014] Wash the freshly collected Patonia herb, cut into 2cm wide slices, add 1 times the weight of the medicinal material in water, stir for 30 minutes, and squeeze 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 obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the above-mentioned 3 times Patonia herbal juice, filter with a 100-mesh sieve, concentrate the filtrate under reduced pressure, and set the temperature at 70°C. When the relative density of the obtained concentrated extract was 1.05, it was transferred to a -20°C refrigerator and frozen for 8 hours. Freeze-dry after taking out the frozen material, the temperature is set at -40°C, the pressure is 0.09Mpa, and the time is 48 hours. Collect the freeze-dried product, pulverize it, pass through a 100-mesh sieve, pack it into bags, 1kg / bag,...

Abstract

The invention discloses a preparation process of a herba patriniae freshly-squeezed freeze-drying powder decoction piece. The process comprises the steps of after herba patriniae harvest, selecting, drip washing, freshly squeezing, and filtering the herb juice; adding water into herb residues, filtrating and squeezing. The obtained herb juice is combined, then concentrated under reduced pressure, and freeze-dried. The herba patriniae powder decoction piece prepared by the method simultaneously retains the polar and non-polar active ingredients in the herba patriniae to the maximum extent. The decoction piece is convenient to store and transport, easy to adjust, controllable in quality, and reliable in efficacy, and is of great significance to protect the clinical efficacy of traditional Chinese medicine. The promotion and implementation of the method has notable social significance 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 Patrinia chinensis. Background technique [0002] Patrinia, a traditional Chinese medicine, is the rooted whole plant of Patrinaceae herb, Huanghua and Baihua. It has the functions of clearing away heat and detoxifying, removing blood stasis and draining pus. Clinically, it is commonly used in the treatment of diseases such as appendicitis, dysentery, enteritis, hepatitis, conjunctivitis, postpartum blood stasis and abdominal pain, carbuncle and furuncle. [0003] Commonly used Patrinia decoction pieces are processed as follows: after harvesting, impurities are removed, dried in the sun, and directly packaged for storage and transportation. The hygienic indicators of these dried Patrinia can not reach the standard, and the medicinal material is prone to mildew, which leads to the decline...
