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 Eclipta medicinal material used for extraction is also dried and stored for a long time, the loss of active ingredients is also very large

Embodiment 1

[0013] Wash the freshly collected Eclipta medicinal material, cut it into 1cm segments, add 0.5 times the weight of the medicinal material in water, stir for 15 minutes, squeeze it while it is fresh, and reserve 0.1% of the virgin medicinal juice for later use. Add 2 times the amount of tap water to the obtained medicinal dregs, stir for 20 minutes, and press a plate-and-frame filter press to extract the medicinal juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the Eclipta medicinal juice obtained by pressing for the above 3 times, and pass through a 100-mesh sieve. The filtrate was concentrated under reduced pressure and the temperature was set at 60 °C. When the relative density of the concentrated solution obtained by concentration is 1.02, spray drying is carried out, the temperature of the air inlet is 140° C., and the temperature of the air outlet is 110° C. Collect the spray-dried product, pulverize it, a...

Embodiment 2

[0015] Wash the freshly collected Eclipta medicinal material, cut it into 2cm sections, add 1 times the weight of the medicinal material in water, stir for 30 minutes, squeeze it while it is fresh, and reserve 0.5% of the virgin medicinal juice for later use. Add 5 times the amount of tap water to the obtained medicinal dregs, stir for 30 minutes, and press the plate and frame filter press to extract the medicinal juice. The obtained medicinal dregs are squeezed with an extruder, and the medicinal juice is filtered. Combine the Eclipta medicinal juice obtained by pressing for the above three times, and pass through 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 solution obtained by concentration is 1.05, spray drying is carried out, the temperature of the air inlet is 120° C., and the temperature of the air outlet is 90° C. Collect the spray-dried product, pulverize it...

Abstract

The invention discloses a preparation process of freshly squeezed spray-dried granule decoction pieces of Eclipta chinensis. In this process, after the Eclipta medicinal material is harvested, it is cleaned, rinsed, squeezed while it is fresh, and the medicinal juice is filtered. The dregs are added with water, stirred, filtered and pressed. The obtained medicinal juices are combined, concentrated under reduced pressure, spray-dried and granulated. The Eclipta granules decoction pieces prepared by this method retain the polar and non-polar active ingredients in the medicinal materials to the greatest extent. The decoction pieces are convenient for storage and transportation, convenient for dispensing, controllable in quality, and reliable in curative effect, which is of great significance to guarantee the clinical curative effect of traditional Chinese medicine. The popularization and implementation of this Law will have significant social and economic benefits.

Description

technical field [0001] The invention belongs to the field of processing Chinese medicinal materials, and in particular relates to a processing technology of decoction pieces of the traditional Chinese medicine Eclipta chinensis. Background technique [0002] The traditional Chinese medicine Eclipta chinensis is a plant of the Compositae family. Eclipta prostrata The dry aerial part of L. Harvested when the flowers bloom, dried in the sun. [0003] This taste is sweet, sour, cold in nature, and returns to the kidney and liver channels. It has the functions of nourishing liver and kidney, cooling blood and stopping bleeding. Mainly used for liver and kidney yin deficiency, loose teeth, premature graying of beard and hair, dizziness and tinnitus, soreness of waist and knees, yin deficiency and blood heat, vomiting blood, epistaxis, hematuria, bloody dysentery, uterine bleeding, traumatic bleeding. [0004] The commonly used processing methods of Eclipta decoction pieces are...
