Abstract

The invention discloses a preparation method of a phoenix-tail fern fresh-squeezed freeze-dried powdery decoction piece. The preparation method comprises phoenix-tail fern harvest, cleaning and selection, leaching, fresh-squeezing, drug juice filtration, mixing of drug dregs and water, drug dreg filtration and squeezing, drug juice mixing, reduced pressure concentration, and freeze drying. The phoenix-tail fern fresh-squeezed freeze-dried powdery decoction piece maximally retains polar and non-polar active ingredients of drugs, is easy to store, transport and blend, has controllable quality and reliable effects and has a significant meaning for guaranteeing the clinical efficacy of traditional Chinese medicine. The promotion and implementation of the preparation method produce prominent social significance and economic benefits.

Example Embodiment

[0011] Example 1
[0012] Wash the freshly collected phoenix tail herbs and cut them into 1cm-long sections. Add 0.5 times the weight of the herbs and stir for 15 minutes to extract the juice. Add 2 times the amount of tap water to the obtained medicine residue, stir for 20 minutes, and squeeze the juice with a plate and frame filter press. The obtained medicinal residue is squeezed by a squeezer, and the medicinal juice is filtered out. Combine the above three phoenix tail herbal juices, filter with a 60-mesh sieve, and concentrate the filtrate under reduced pressure, and set the temperature to 60°C. When the relative density of the concentrated extract is 1.10, it is transferred to the refrigerator at -20°C and frozen for 12 hours. After taking out the frozen material, it is freeze-dried, the temperature is set to -18°C, the pressure is 0.09Mpa, and the time is 24 hours. Collect the lyophilized material, crush, pass through a 60-mesh sieve, bag it, 1kg/bag, add the bagged antioxidant and desiccant, vacuum package, and label it.

Example Embodiment

[0013] Example 2
[0014] Wash the freshly collected phoenix tail herbs, cut them into 2cm-long sections, add water equal to 1 times the weight of the herbs, stir for 30 minutes, and squeeze the juice while it is fresh. Add 5 times the amount of tap water to the obtained medicine residue, stir for 30 minutes, and squeeze the juice with a plate and frame filter press. The obtained medicinal residue is squeezed by a squeezer, and the medicinal juice is filtered out. Combine the above three phoenix tail herbal juices, filter with a 100-mesh sieve, and concentrate the filtrate under reduced pressure, and set the temperature to 70°C. When the relative density of the concentrated extract is 1.05, it is transferred to the refrigerator at -20°C and frozen for 8 hours. After taking out the frozen material, it is freeze-dried, the temperature is set to -40°C, the pressure is 0.09Mpa, and the time is 48 hours. Collect the lyophilized material, crush, pass through a 100-mesh sieve, bag it, 1kg/bag, add the bag antioxidant and desiccant, vacuum package, and label it.
