Abstract

The invention belongs to the technical field of extraction of plants, in particular to an extraction method of gastrodin in wild rhizoma gastrodiae. The extraction method disclosed by the invention has the advantages that extraction of the gastrodin in the wild rhizoma gastrodiae with high content of the gastrodin is carried out, and because the wild rhizoma gastrodiae contains more medicinal ingredients, that is, gastrodin and gastrodioside citronellol, a flavor of the rhizoma gastrodiae planted through artificial cultivation cannot be compatible with the special flavor of the wild rhizoma gastrodiae; specially on the long lasting of the smell, after common rhizoma gastrodiae is put on a counter, people basically cannot smell the scent, on the contrary, the wild rhizoma gastrodiae is different, even the wild rhizoma gastrodiae is dried for a period of time, the smell can keep lasting for long time and cannot fade away, so the the extraction quantity of the gastrodin ensured; and meanwhile, through proportioning of ethanol solutions with appropriate concentration, the gastrodin is dissolved under an appropriate environment, and spray drying is carried out under a high vacuum environment, so that paste forming ratios of the gastrodin can be increased, the overall operation difficulty is lower, and the extraction efficiency is higher.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a method for extracting gastrodin in wild gastrodia elata. Background technique [0002] Gastrodin This product is extracted from the dried root of the orchid plant Gastrodia elata, and the raw material is produced in Yunnan. Gastrodin has good sedative and hypnotic effects, and can relieve neurasthenia, insomnia, and headache symptoms. The traditional Chinese medicine Gastrodia elata can treat dizziness, numbness, and convulsions. Clinical application: treatment of vertebral-basilar artery insufficiency; treatment of vestibular neuronitis; treatment of vertigo. Wild Gastrodia elata is a rare and precious medicinal plant, which is used to treat high blood pressure, headache, dizziness, crooked mouth and eyes, numbness of limbs, and convulsions in children. Its tubers are good medicine for calming liver and wind. Wild Gastrodia elata contains more medicinal...
