Problems solved by technology

There are many disadvantages in this traditional planting and harvesting: 1. The planting cycle is too long, generally more than 15 years; 2. Too long time and capital investment seriously affect the enthusiasm of farmers; 3. It takes 15 years to cut down The bark of the growing yellow bark is used as medicine. Even girdling and other methods will increase the cost and cause the death of the yellow bark tree, which is a great damage to wild resources.
Traditional planting methods cannot achieve the goal of increasing farmers’ income as soon as possible, which affects the enthusiasm of the majority of drug farmers, resulting in a shortage of medicinal resources on the market and rising prices of medicinal materials, especially the extraction of berberine based on Cortex Phellodendri. pressure

Embodiment 1

[0044] Except that the planting spacing is changed to 20cm×60cm, and the planting density is changed to 5500 plants / acre, the same method of comparative example 1 is used to plant the yellow bark tree, and the yellow bark tree stem is picked and weighed.

[0045] Results: The average single plant produces 63g of stem bark, and the bark berberine content is 4.58% (dry basis), 350kg of stem bark per mu, 117kg of stem bark per mu per mu, 16kg of berberine per mu, and 16kg of berberine per mu. The yield per mu of berberine is 5.3kg.

Embodiment 2

[0047] Except that the planting distance is changed to 15cm×60cm, and the planting density is changed to 7400 plants / acre, the same method is used to plant the yellow bark tree, pick the yellow bark tree stem and weigh it.

[0048] Results: The average single plant produces 57g of dry stem bark, the bark berberine content is 4.34% (dry basis), the yield of stem bark per mu is 420kg, the average annual yield of stem bark is 140kg, and the berberine per mu is 18kg. The yield per mu of berberine is 6kg.

Embodiment 3

[0050] Except that the planting distance is changed to 15cm×55cm, and the planting density is changed to 8000 plants / acre, the same method of comparative example 1 is used to plant the yellow bark tree, pick the yellow bark tree stem and weigh it.

[0051] Result: The average single plant produces 55g of dry stem bark, the bark berberine content is 4.29% (dry basis), the yield of stem bark per mu is 440kg, the annual average yield of stem bark per mu is 147kg, and the berberine per mu is 18.9kg. The average yield per mu of berberine is 6.3kg.

Abstract

The invention discloses a preparation method of a berberine raw material, which is particularly comprises the following steps of: picking bark of phellodendron Chinense schneid with planting years of 3 to 5 years and using the bark of the phellodendron Chinense schneid as the raw material to prepare berberine, wherein the planting density of the phellodendron Chinense schneid is 5,500 to 8,000 plants per mu and the planting spacing is 15cm*50cm to 20cm*60cm. The method has the advantages of high land utilization rate, cycled production, high effect yielding speed, high investment response speed, high planting enthusiasm of farmers, benefits for scale and standardization production, promotion for sustainable utilization of phellodendron Chinense schneid resources and the like.

Description

technical field [0001] The invention relates to a method for obtaining a raw material of traditional Chinese medicine, in particular to a method for obtaining a raw material of berberine. Background technique [0002] Phellodendron chinense is the dry bark of Phellodendron chinense Schneid., a plant of the genus Phellodendron in Rutaceae, and is commonly called "Phellodendron chinense Schneid." Wampbark often grows by rivers and deep mountains, and is widely distributed in my country. It is produced in Hunan, Hubei, Sichuan, the three northeastern provinces, Hebei, Inner Mongolia, Yunnan, Guizhou, Guangxi, Shandong, Gansu, and Zhejiang. [0003] Phellodendron Phellodendron, as a traditional Chinese medicine, has shown high clinical application value and development potential. It has a wide range of pharmacological activities, such as antibacterial, antiviral, antitussive, antihypertensive, and immune enhancement. Phellodendron Phellodendri has been widely used in the devel...
