Description
Technical field
The present invention relates to a kind of method of mineral Chinese medicine being carried out to quality judging, the true and false quality evaluation of Chinese medicine calamine,The particularly optical characteristics to Chinese medicine calamine stone end and the discriminating of microscopic features.
Background technology
Calamine (Galamina) is external application mineral drug, has removing toxic substances removing nebula, effect of the antipruritic sore of hygroscopic, curative effectSignificantly, successive dynasties medical book is all on the books. China's pharmacopeia regulation[1], the source of calamine is carbonate mineral calcite family smithsonite(smithsonite, main containing ZnCO3). But nearly two, 30 years, on medicinal material market, the calamine in smithsonite source is in great shortage, severalDo not sell, on market, occurred in a large number with marionite (hydrozincite, the main Zn that contains5(CO3)2(OH)6) be Ji YuanCalamine, and in a large number with calcite (calcite, the main CaCO that contains3) be the adulterant calamine of Ji Yuan, cause base source confusion, puppetProduct spread unchecked.
On mineralogy, smithsonite is trigonal system, is the secondary mineral in lead-zinc deposit oxidized zone[2]. Marionite is singleOblique system, is also mineral distributed more widely in lead-zinc deposit oxidized zone, is formed by zincblende oxidization enrichment[3]. Marionite and water chestnutZinc ore is containing zinc carbonate mineral, both secondary minerals of lead-zinc deposit oxidized zone, Chang Gongsheng[4]. Calcite is alsoTrigonal system. Also be carbonate mineral, cleavage, is the planar crystal of water chestnut more completely, also has the column of being and tabular person. Color mostlyFor colourless or milky, extensively distribute at nature.
As carbonate mineral, marionite, smithsonite, calcite etc. also can carry out qualitative discriminating by mineral thin slice,But traditional mineral thin slice requires to use relatively large mineral could prepare through process consuming time, effort such as cut into slices, boil glue, abrasive disc etc.,And mineral Chinese medicine is often to appear at medical market with the form of powder, there is larger variation in its form, traditional dependencePrepare the method that mineral thin slice identifies mineral and be very limited, and very long thin slice preparation process is also unfavorable for medicineThing carries out quick, instant inspection and judgement.
The present invention, by preparing fast particle slide glass, particle oil sheet, can effectively realize the instant of the sweet stone powder of Chinese medicine furnaceDifferentiate.
Summary of the invention
The present invention is directed to the blank that current mineral Chinese medicine powder is differentiated, proposed a set of method of discrimination and index.
The technical problem that the present invention solves is achieved through the following technical solutions, the micro-and light of the sweet stone powder of Chinese medicine furnaceProperty discrimination method, its feature is as follows:
(1) preparation of sample: by calamine powder granulation slide glass, and/or make oily sheet and normalized optical thin slice.
(2) test is used instrument: polarised light light microscope.
(3) testing procedure:
A, utilize morphological feature, the grain structure feature of microscopic particle slide glass in air dielectric, as: form classType, homogenieity, color, pleochroism etc., judge the fundamental type of mineral assemblage.
The features such as b, the projection of utilizing microscopic oil sheet (or standard mating plate), exasperate, Becke line, judge variable grainRefractive index, extinction. Determine its mineral assemblage characteristics.
C, with class gel mineral difference. Utilize the optical characteristics difference of different minerals to distinguish.
D, with the difference of adulterant. Utilize special optical characteristic and the adulterant of calamine to distinguish.
(4) set up discrimination standard
The microoptic feature of a, the sweet stone powder of confirmation Chinese medicine furnace.
Existence form and the kind of major impurity mineral in b, qualification calamine.
C, identify the optical microphotograph feature of common calamine adulterant.

Specific embodiments
Diagnostic feature is: the microoptic feature of calamine powder, the microoptic feature of impure mineral, common adulterantDistinguish.
(1) preparation of sample: by direct calamine powder granulation slide glass, and/or particle slide glass is dripped to medium oilMake oily sheet, in time, prepares, immediately observes.
(2) test is used instrument: polarised light light microscope.
(3) testing procedure:
A, utilize morphological feature, the grain structure feature of microscopic particle slide glass in air dielectric, as: transmitted lightThe morphotype of particle, homogenieity, the grain color etc. of particle in lower sample, under single polarisation, observe sample in particle pleochroismDeng, under cross-polarized light, observe the light transmission of sample etc., judge the fundamental type of mineral assemblage.
B, utilize the features such as the projection of microscopic sample particle in oily sheet, exasperate, Becke line, judge variable grainRefractive index, extinction. Determine its mineral assemblage characteristics. The refractive index of oil sheet used oil, 1.46～1.55, most preferably is foldingPenetrate rate 1.52～1.54.
C, with class gel mineral difference. Utilize the optical characteristics difference of different minerals to distinguish smithsonite and marionite.
D, with the difference of adulterant. Distinguish with common adulterant calcite.
(4) set up discrimination standard
The microoptic feature of a, the sweet stone powder of confirmation Chinese medicine furnace.
Existence form and the kind of major impurity mineral in b, qualification calamine.
C, identify the optical microphotograph feature of common calamine adulterant.
