Abstract

The present application discloses noble dendrobium powder having a particle size of 150 to 180 mu m. The content of dendrine selected as a detection object in rat plasma is determined by an ultra performance liquid chromatography-mass spectrometry (UPLC-MS) technique, and the absorption of the noble dendrobium powder of different particle sizes in vivo can be quantitatively evaluated. By combination of the pharmacokinetic study method of noble dendrobium in a rat body, the content of the dendrine in the rat plasma can be determined by the ultra performance liquid chromatography-mass spectrometry (UPLC-MS) technique, experiments find that compared with the SD rat orally administered with 0.8g/kg of noble dendrobium ultrafine powder (45mu m), the SD rat orally administered with 0.8g/kg of noble dendrobium fine powder (150-180mu m) has high noble dendrobium fine powder absorption rate, good noble dendrobium fine powder absorption effect and short noble dendrobium fine powder absorption time. Experiment results indicate that unlike other traditional Chinese medicines, the crushed particle size of the noble dendrobium powder is not the smaller, the better, the absorption effect of the noble dendrobium fine powder (150 mu m to 180 mu m) in the body is much stronger than that of the noble dendrobium ultrafine powder (45 mu m).

Description

technical field [0001] The invention belongs to the technical field of preparation of traditional Chinese medicinal materials, in particular to a kind of Dendrobium chinensis and application thereof. Background technique [0002] The traditional Chinese medicine Dendrobium has the functions of nourishing yin and clearing heat, invigorating the stomach and promoting body fluid, moistening the lungs and relieving cough, improving eyesight and strengthening the body. It is clearly stipulated in the 2015 edition of the Chinese Pharmacopoeia that one of the medicinal plant sources of Dendrobium is Dendrobium nobile Lindl. Due to its medicinal effect, its market demand is expanding day by day. How to better develop and utilize the medicinal resource of Dendrobium candidum is one of the focuses of current pharmaceutical research. Dendrobium dendrobium on the existing market is mainly sold as primary products in fresh strips and Fengdou. In the processing of secondary products, the...
