Abstract

The invention discloses a method for preparing medicinal material gastrodia elata. The method includes the following steps that 1, tubers of gastrodia elata are taken and washed to remove soil; 2, the tubers, processed in the step 1, of the gastrodia elata are soaked in a NaCl water solution; 3, the tubers, processed in the step 2, of gastrodia elata are cleaned and naturally dried to obtain the medicinal material gastrodia elata. According to the medicinal material gastrodia elata prepared through the method, the medicine yield is 30-38%, measurements of the shape, properties, thin-layer chromatography identification, water content, alcohol extract and gastrodin content all meet quality standards of the astrodia elata item in Pharmacopoeia of the People's Republic of China, generally, the medicinal material gastrodia elata does not fade or is damaged by worms after being placed for one year, and the nitrite content meets related standards. The provided method solves the problem that the tubers of the gastrodia elata rot or mildew in large quantities in a natural drying method, can replace a sulfur fumigation method and a drying method and has high application value.

Description

technical field [0001] The invention relates to a method for preparing rhizome Chinese medicinal materials, in particular to a method for preparing medicinal gastrodia elata. Background technique [0002] The medicinal material Gastrodia elata is the dry tuber of the orchid plant Gastrodia elata Bl. It is a commonly used precious Chinese medicinal material. It is excavated from the beginning of winter to before the Qingming Festival of the following year. General requirements, wash immediately, steam thoroughly, and dry at low temperature in the open. [0003] Gastrodia elata tubers are relatively thick, and the whole tuber is processed as a medicinal material. After steaming, it needs a long time of low-temperature drying. In case of rainy days, the low-temperature drying time is longer, and often rots, resulting in a large loss of medicinal materials. economic loss. Especially in the main production areas in the southwest of Yunnan, Guizhou and Sichuan, where the relati...
