Dioscorea panthaica product and processing method thereof

Abstract

The invention discloses a dioscorea panthaica product and a processing method thereof. The processing method comprises the following steps that S1, dioscorea panthaica is washed for removal of dirt and impurities and then drained; S2, after draining, the dioscorea panthaica is cut into slices; and S3, the obtained dioscorea panthaica slices are dried at 60-100 DEG C until the water content is 10 wt% or less. By changing a traditional drying method, the content of pseudoprotodioscin in the dioscorea panthaica is raised, being at least three times of the pharmacopoeia standard. Compared with a traditional processing method of the dioscorea panthaica, the work efficiency is improved, the mildew risk is reduced, and processing quality control is achieved.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine processing, in particular to a yellow yam medicinal product and a processing method thereof. Background technique [0002] Yellow yam is the dry rhizome of yellow yam, a plant of Dioscoreaceae. Oblong or irregular thick slices with irregular edges, 1-5mm thick. The outer skin is yellow-brown, with longitudinal wrinkles, and sparse fibrous root residues can be seen. Hard. The cut surface is white or yellowish white, with scattered yellow dot-like vascular bundles, and the section is fibrous. Slight gas, slightly bitter taste. [0003] Yellow yam is distributed in Enshi, Hubei, northwestern Hunan, western Sichuan, western Guizhou, and Yunnan. It often grows under shrubs on hillsides at an altitude of 1000-3500 meters, or is only found on forest edges of dense forests or beside roadsides on hillsides. The rhizome contains diosgenin, which is the raw material for the synthes...

AI Technical Summary

Problems solved by technology

There are no clear regulations on the washing method, cutting method, and drying time of medicinal materials, making it difficult to guarantee the quality, especially the washing method and drying method. The selection of drying method and drying time have a great impact on its active ingredients. According to the traditional processing method, the content of the active ingredient pseudoprotodioscin is relatively low. During the drying process, the pharmacopoeia describes drying in the sun. Due to the humid climate in Hunan, Guizhou, Yunnan and other places, drying in the sun is not easy to dry out, and often occurs Mildew, deterioration and other phenomena
