Abstract
This application discloses a kind of HERBA DENDROBII powder, the grain size of the HERBA DENDROBII powder is 150~180 μm.It selects dendrobine as detection object, the content of dendrobine in rat plasma is detected using ultra performance liquid chromatography mass spectrometry (UPLC MS) technology, quantitatively evaluate the absorbing state of the HERBA DENDROBII powder of different-grain diameter in vivo.In conjunction with pharmacokinetic methods of the HERBA DENDROBII in rat body, the content of dendrobine in the blood plasma measured by UPLC MS, experiment finds that SD Oral Administration in Rats administration HERBA DENDROBII fine powder (150~180 μm) 0.8g/kg is compared with HERBA DENDROBII Ultramicro-powder (45 μm) 0.8g/kg, absorptivity of the HERBA DENDROBII fine powder in rat body is high, good absorption effect, soak time are short.It follows that different with other Chinese medicines, the powder particle diameter of HERBA DENDROBII powder is not the smaller the better, and the assimilation effect of fine powder (150 μm~180 μm) in vivo is much better than Ultramicro-powder (45 μm).
Description
Technical field
The invention belongs to Chinese medicine preparing technical fields, and in particular to a kind of HERBA DENDROBII and its application.
Background technology
The Chinese medicine stem of noble dendrobium has the effects that nourishing Yin and clearing heat, reinforcing stomach reg fluid, moistens the lung and relieve the cough, improving eyesight salubrity, the traditional Chinese medicines in 2015 editions
Clearly stipulate that one of the Source of Drug Plants of the stem of noble dendrobium is HERBA DENDROBII (DendrobiumnobileLindl.) in allusion quotation, it is based on stone
The drug action of dry measure used in former times, market demand are growing, and it is existing for how preferably developing and using HERBA DENDROBII this medicine resource
In one of study of pharmacy emphasis.HERBA DENDROBII on existing market mainly carries out primary product sale with fresh item, maple bucket.Secondary production
In the processing of product, the powder particle diameter degree of HERBA DENDROBII dry product does not provide explicitly, and the powder of what specific grain size can be preferably
In absorption of human body and distribution, also there are no relevant reported literatures.
In the production and preparation process of Chinese medicine preparation, it is necessary to carry out Crushing of Ultrafine to raw medicinal material, can be only achieved preparation work
Skill requirement.In general, in the preparation containing micro-powder of Chinese herbs, micro mist is thinner, and quality is higher.Micro mist generally refers to grain size 1
The powder of~75 μ ms, micro mist average grain diameter are generally less than 75 μm (traditional Chinese medicine beats powder at 100 μm or more).In this fineness
Under, 90% or more plant cell is broken, and is conducive to the absorption of drug and the raising of curative effect, is conducive to the release and suction of drug
Receipts drug-eluting rate is directly proportional to surface area (S) of drug, and the drug of equivalent, particle is smaller, and S is bigger, is more conducive to drug
Dissolution and absorption.The powder very little of micron Chinese medicine, cell-wall breaking ratio is high, active ingredient just exposure before not entering into body
Out, into after in vivo, soluble component dissolves rapidly, because of powder very little solubility low ingredient, has larger
Adhesive force and be firmly adhered on mucous membrane, thus be conducive to the absorption of drug.However, for HERBA DENDROBII, if crush journey
Degree is higher, and the bioavilability of drug is higherThe present invention is ground from the pharmacokinetics of the HERBA DENDROBII powder of different-grain diameter
Study carefully and set out, it was demonstrated that the absorbing state of the powder of clear grain size determines the powder diameter of optimum utilization.
Invention content
Smaller for the Chinese medicine grain size of the prior art, the better technology prejudice of assimilation effect, the present invention proposes one kind
HERBA DENDROBII fine powder more better than HERBA DENDROBII Ultramicro-powder assimilation effect.
