GPA planting method of Lycoris aurea

Abstract

The invention discloses a GPA planting method of Lycoris aurea. Harvested flowers of the Lycoris aurea can be used as raw medicinal materials for extracting galanthamine. The method includes the six main steps of plantation building, propagation method implementation, planting, field management, pest control, and harvesting, processing and storage. By replacing wild resources with artificially-cultivated Lycoris aurea resources, the ecological environment can be effectively projected, water and soil loss can be prevented, and market supply of raw medicinal materials of the galanthamine and clinical medication safety of the galanthamine can be guaranteed as well. Because the overground flowers of the Lycoris aurea are used as the raw medicinal materials for extracting the galanthamine, labor intensity is small, the proportion of labor cost is small, and production cost is low. The standard operating procedure of each production link is worked out for the first time. The content of the galanthamine in the dried flowers, used as the raw medicinal materials, of the Lycoris aurea produced through the method is much higher than that in bulbs used as raw medicinal materials for producing galanthamine in a pharmaceutical factory in the prior art. Lycoris aurea industrialization and GAP standardized artificial cultivation are achieved through the method.

Description

technical field [0001] The invention relates to a GAP planting method and a standard operating procedure of Lycoris chrysalis. Harvested flowers of Lycoris chrysalis are used as raw materials for extracting galantamine. Background technique [0002] GAP of Chinese herbal medicines: Good Agricultural Practices (GAP for short) of Chinese herbal medicines. Galantamine chemical name: 11-methyl-3-methoxy-4α,5,9,10,11,12-hexahydro-6H-benzofuro[3α,2-ef]benzazepine Ezol-6-ol hydrobromide. The English name galantamine, Reminy1, is a phenanthridine alkaloid derived from Amaryllis genus. It is a reversible cholinesterase inhibitor, which can pass through the blood-brain barrier, restore the hindered neuromuscular conduction, and improve various diseases. A paralyzed state of peripheral neuromuscular disorders. In the 1960s, Galantamine (trade name: Qiangji Tablets, Nivalin, tablets) was mainly used to treat sequelae of poliomyelitis (poliomyelitis), muscle atrophy, postoperative par...

Problems solved by technology

In the past, the traditional raw material for extracting galantamine was to dig the underground bulbs of Amaryllis chrysanthemum. It takes 3-4 years to dig out after planting a crop. The growth cycle is long and the investment is large, and only one-time income is obtained. Planting and digging medicinal bulbs The labor intensity is high, the labor cost ratio is large, and the production cost is high
