Abstract

The invention relates to a detection method for a Gymnadenia conopsea medicinal material. The Gymnadenia conopsea medicinal material is detected by one or more of thin layer chromatographic identification, polysaccharide content detection, feature spectrum peak and gastrodin content detection methods; the thin layer chromatographic identification method has high specificity and high sensitivity; the internal quality of the Gymnadenia conopsea medicinal material can be further measured by performing content detection on polysaccharide and gastrodin; feature spectrum with pertinence and the detection method thereof are selected through tests, so that the Gymnadenia conopsea can be detected accurately.

Description

technical field [0001] The invention relates to a detection method of medicinal materials, in particular to a detection method of hand ginseng medicinal materials, and belongs to the technical field of medicine. Background technique [0002] Ginseng, Tibetan name "Wangla", is the tuber root of Gymnadenia conopsea (L.) R.Br., a plant of the genus Gymnadenia conopsea (L.) R.Br., which has a good effect of replenishing essence and marrow, enhancing physical fitness, promoting body fluid and quenching thirst, and calming nerves. It is commonly used in Tibetan and Mongolian medicine prescriptions for invigorating the kidney. [0003] At present, there are few researches on the detection methods of hand ginseng, and the foundation is weak. The literature "HPLC Determination of the Contents of 4 Active Components in Tibetan Medicine Ginseng Wangla" (Chinese Journal of Traditional Chinese Medicine, Issue 14, 2009, referred to as "Document 1") introduced a method for the simultaneou...
