Abstract

The invention relates to a low temperature and atmospheric pressure plasma extraction technology of rhodioloside, and belongs to the technical field of extraction of effective components in traditional Chinese medicines. Boiling extraction is adopted and assisted with low temperature and atmospheric pressure plasma extraction, coarse separation of macroporous adsorption resin and silicone rectification, so that the problem that the high-purity rhodioloside cannot be efficiently extracted by the prior art is solved. By adopting control parameters disclosed by the invention, the low temperature and atmospheric pressure plasma treatment technology can be led to traditional Chinese medicine extraction, so that the high-purity rhodioloside can be efficiently extracted.

Description

technical field [0001] The invention relates to a method for extracting effective components in traditional Chinese medicine, more specifically, the invention relates to a low-temperature and atmospheric-pressure plasma extraction process for salidroside, which belongs to the technical field of extracting effective components in traditional Chinese medicine. Background technique [0002] Rhodiola rosea, perennial herb, 10-20 cm high. The roots are thick, conical, fleshy, brownish yellow, with many fibrous roots at the root neck. Rhizome short, stout, terete, covered by numerous imbricate scale-like leaves. Several flower stems are extracted from the leaf axils at the top of the stem. The upper and lower parts of the flower stems have fleshy leaves, the leaves are elliptic, with serrated edges, sharp apex, cuneate base, almost sessile. Cymes terminal, flowers red. Harvest from July to September. [0003] Rhodiola contains salidroside, herbalin-7-rhamnoside, herbalanin-7-g...
