Embodiment 1

[0016] Example 1 Preparation of Hainan Jiujie Leaf Extract

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

[0018] (1) Distilled water extraction test of Hainan Jiujie leaves

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

[0020] 2. Screening of extraction time: set the extraction times as 3 times, and the material ratio (mL / g) of extraction solvent and medicinal materials as 15:1. 5h, 7.5h, 10h to determine the appropriate extraction time for each time.

[0021] 3. Screening of the material ratio (mL / g) of the extraction solvent to the medicinal material: set the extraction times as 3 times and the extraction time as 2.0h, 1.5h and 1.0h respectively. The material ratios of 1:1, 5:1, 10:1, 15:1, 20:1, 30:1 were tested to determine...

Embodiment 2

[0033] Example 2 Preparation of Pittosporum chinensis extract

[0034] Weigh 100 g of Pittosporum chinensis medicinal materials, pulverize, pass through a 60-mesh sieve, add 1500 mL 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. 1500 mL of distilled water was added to the medicinal residues for the second water extraction, and the extraction time was 1.5 hours. After the extraction was completed, the medicinal residues were filtered and the filtrate was collected. 1500 mL of distilled water was added to the medicinal residues to continue the third water extraction. The extraction time was 1 hour. After the extraction was completed, the medicinal residues were filtered and the filtrate was collected. The three aqueous extracts were combined and concentrated to obtain an aqueous extract concentrate. After the water...

[0035] Example 3 Preparation of Rooting Root Extract

[0036]Weigh 100 g of the medicinal materials for rooting, pulverize, pass through a 60-mesh sieve, add 1500 mL 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. 1500 mL of distilled water was added to the medicinal residues for the second water extraction, and the extraction time was 1.5 hours. After the extraction was completed, the medicinal residues were filtered and the filtrate was collected. 1500 mL of distilled water was added to the medicinal residues to continue the third water extraction. The extraction time was 1 hour. After the extraction was completed, the medicinal residues were filtered and the filtrate was collected. The three aqueous extracts were combined and concentrated to obtain an aqueous extract concentrate. After the water-extracted conce...

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 extraction is 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 medicine dregs, 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 extracted are 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 with the effect of promoting fracture healing. Background technique [0002] Hainan Jiujie Psychotria hainanensis is a Rubiaceae plant, also known as Shan Da Dao and Qinglong Tuzhu. Root and leaf medicine, bitter in taste, astringent, cool in nature, has the effects of clearing away heat and detoxification, reducing swelling and removing toxins, dispelling wind and dampness, promoting blood circulation and relieving pain, and is mainly used for colds, diphtheria, dysentery, traumatic injury, and unknown swelling and pain. Foreign scholars have isolated polyindolenine alkaloids from the plant of Rubiaceae, Psyehotriaforstcriana A.Gray. . Foreign Medicinal Botanicals, 1990, 5(5): 230-231.). In Hainan Island, my country, the Li people use their stems and leaves to tre...
