Embodiment 1

[0016] The preparation of embodiment 1 Hainan Jiujieye extract

[0017] Hainan Jiujie leaves are crushed, passed through a 60-mesh sieve, and stored for later use.

[0018] (1) Extraction test of Hainan Jiujieye with distilled water

[0019] 1. Screening of extraction times: set the material ratio (mL / g) of the extraction solvent to the medicinal material to 15:1, extract 2.5 hours each time, and extract 1, 2, 3, 4, 5 times respectively to determine the appropriate extraction frequency.

[0020] 2. Screening of extraction time: Set the number of extractions to 3 times, and the material ratio (mL / g) of the extraction solvent to the medicinal material is 15:1. Under this condition, extract 0.5h, 2.5h, 3.5h, 5h, 7.5h, 10h, to determine the appropriate extraction time each time.

[0021] 3. Screening of the material ratio (mL / g) between the extraction solvent and the medicinal material: set the number of extractions to 3 times, and the extraction time is 2.0h, 1.5h, and 1.0h re...

Embodiment 2

[0033] The preparation of embodiment two Pittosporum extract

[0034] Weigh 100g of Pittonia chinensis medicinal material, pulverize it, pass through a 60-mesh sieve, add 1500mL of distilled water to soak for 1 hour, and then carry out the first water extraction. The water extraction time is 2 hours. After the extraction is completed, filter the medicinal residues and collect the filtrate. Add 1500mL of distilled water to the dregs for the second water extraction. The extraction time is 1.5 hours. After the extraction is complete, filter the dregs and collect the filtrate. Then add 1500mL of distilled water to the dregs to continue the third water extraction. The extraction time is 1 hour. After the extraction is completed, the dregs are filtered and the filtrate is collected. The three water extracts were combined and concentrated to obtain a water extract concentrate. After the water-extracted concentrated solution was vacuum freeze-dried for 24 hours, the freeze-dried powd...

Embodiment 3

[0035] The preparation of the root extract of embodiment three

[0036]Weigh 100g of the ground root medicinal material, pulverize it, pass through a 60-mesh sieve, add 1500mL of distilled water to soak for 1 hour, and then perform the first water extraction. The water extraction time is 2 hours. After the extraction is completed, filter the medicinal residues and collect the filtrate. Add 1500mL of distilled water to the dregs for the second water extraction. The extraction time is 1.5 hours. After the extraction is complete, filter the dregs and collect the filtrate. Then add 1500mL of distilled water to the dregs to continue the third water extraction. The extraction time is 1 hour. After the extraction is completed, the dregs are filtered and the filtrate is collected. The three water extracts were combined and concentrated to obtain a water extract concentrate. After the water-extracted concentrated solution was vacuum freeze-dried for 24 hours, the freeze-dried powder w...

Abstract

The invention discloses a preparation method of a traditional Chinese medicinal extract with the effect of enhancing fracture healing. The preparation method is characterized by comprising the following steps of: after crushing of Hainan nine-section leaves, scaevola sericea and kalanchoe pinnata medicines, firstly applying distilled water for extraction with the material ratio of an extraction solvent and the medicines being 15:1, extracting for three times totally, adopting equivalent decreasing mode for each extraction time being 2 hours, 1.5 hours and 1 hour respectively; after extractionis finished, filtering medicine dregs, collecting and combining filtrate, concentrating and obtaining concentrated liquor extracted by the distilled water of the medicines; after the medicine dregs are dried, applying 95% alcohol to carry out backflow extraction, extracting for two times totally with the extraction time being 2 hours and 1.5 hours; after extraction is finished, filtering medicinedregs, collecting and combining filtrate, recovering the solvent, obtaining concentrated liquor extracted by the 95% alcohol of the medicines; and after the two types of concentrated liquor extractedare vacuum-frozen and dried for 24 hours, obtaining dry medicine powder, carrying out vacuum drying on the medicines, then weighing the obtained dry powder, and respectively calculating the extraction rate of the distilled water and the alcohol.

Description

technical field [0001] The invention relates to a preparation method of a group of traditional Chinese medicine extracts, in particular to a preparation method of a group of traditional Chinese medicine extracts capable of promoting fracture healing. Background technique [0002] Psychotria hainanensis is a Rubiaceae plant, also known as Shandao and Qinglongtuzhu. It is an evergreen shrub with strong resistance to shade and likes a warm, humid and sunny environment. The roots and leaves are bitter, astringent, and cool in nature. They have the effects of clearing heat and detoxification, reducing swelling and pulling out toxins, expelling wind and dampness, promoting blood circulation and relieving pain. Foreign scholars isolated polyindolenine alkaloids from PsyehotriaforstcrianaA.Gray. in Rubiaceae (the interaction between polyindolenine alkaloids and nucleotides in the genus Psyehotriaforstcriana[J] .Foreign Medicine and Plant Drugs Volume, 1990, 5(5): 230-231.). In Hai...
