Abstract
The present invention provides a kind of Radix Astragali using growth year as foundation and graded method.The growth ring of Milkvetch Root upper-lower section diverse location is obtained by free-hand section and phloroglucin concentrated hydrochloric acid staining technique, Radix Astragali upper-lower section growth year is determined according to growth ring.Milkvetch Root is divided into different Radix Astragali sections according to this method, growth ring number it is consistent be classified as respective level, the wherein more growth year of growth ring number is longer, and respective level is higher.The present invention is simple and easy to operate, solves the problems, such as that current Radix Astragali commercial grade can not react growth year, is laid a good foundation for the classifying rationally of Milkvetch Root commercial specification grade.
Description
Technical field
The present invention relates to Chinese medicine technical field of quality identification, particularly belongs to a kind of Huang for differentiating growth year with growth ring
Stilbene medicinal material grading method.
Background technology
Certified products Milkvetch Root as defined in Chinese Pharmacopoeia 2015 editions is leguminous herbaceous plant's Astragalus astragalus mongolicus
Astragalus membranaceus (Fisch.) Bge.var.mongholicus (Bge.) Hsiao or Astragalus membranacus
A.membranaceus (Fisch.) Bge. dry root.The imitative wild Mongolia of Shanxi Hengshan Mountain mountain range (Huiyuan, Ying County etc.) production is yellow
Stilbene, have main root slightly grow, branch is few, mealiness foot, beany flavor is dense, it is sweet the features such as, be generally acknowledged genunie medicinal materials.
Radix Astragali commodity transaction at present is carried out by grade, and Radix Astragali manufacturing enterprise Main Basiss diameter establishes specification grade standard,
Differentiate Radix Astragali quality height.During each Habitat producing, crop truncates to cut lateral root and is blended in main root root bar first, then by thickness
Root bar is divided into different grades of root segment, diameter is big, grade is high, price is also high." the different commercial grade Radix Astragali quality such as Li Zhenyu
Evaluation study " [J] Chinese medicines, 2015,38 (6):1186-1190. has found current commercial specification classification standard (diameter) and quality
Comment control index can not embody the quality good or not of Milkvetch Root.
As Chinese medicine commercial specification classification standard, not only different size grade medicinal material can be distinguished from appearance features, together
When can also reflect growth year.Wang Wen congruences " influence that growth year accumulates to flavones in the Radix Astragali and saponin component content "
[J] Chinese medicines, 2015,7 (7):1366-1369. researchs are found with the increase of growth year, flavones and soap in Milkvetch Root
Methods of glycosides content is in elevated trend, and accumulation of the growth year to this two constituents has a great influence year by year, it is seen that Radix Astragali medicine
The quality of material and growth year are closely related.However, the Radix Astragali is different from ginseng, still can not be from the outward appearance such as aerial part and root, stem
Morphological Identification growth year.The present invention is based on this characteristic of growth ring, free-hand section technology and phloroglucin-dense salt in astragalus root
Sour staining technique is studied the growth ring phenomenon in astragalus root, upper in analysis different years astragalus root and same astragalus root,
Hypomere growth ring number difference, the correlation of growth ring and actual growth year is summarized, established a kind of fast and convenient with growth
Take turns the Radix Astragali growth year authentication method that number is foundation.Milkvetch Root is divided into different Radix Astragali sections according to this method simultaneously, it is raw
Long wheel number it is consistent be classified as respective level, the wherein more growth year of growth ring number is longer, and respective level is higher.Establish
Radix Astragali segmentation method using growth year as foundation, and then realize the classifying rationally of the method graded to Radix Astragali commercial specification grade
Significant, this method is there is not yet document report.
The typically growth of the wild Radix Astragali to be imitated to excavate within 4 years or more than 4 years, same root Radix Astragali upper and lower side growth ring number is inconsistent,
Upper end diameter is thick, growth ring number is more, and the small growth ring number of lower end diameter is few.But current grade separation standard not with definitely
Growth year it is completely corresponding.Same astragalus root different-diameter section, growth ring number is inconsistent, and growth year is different, ought to draw
Assign to different grades；Growth ring number it is consistent be divided into same grade.
The content of the invention
Grade method it is an object of the invention to provide a kind of Radix Astragali using growth year as foundation.
A kind of Radix Astragali using growth year as foundation provided by the invention grades method, comprises the following steps：
1) finished product bar, is taken, removes hollow part, with cold water flush to no-sundries, is placed in 50~60 DEG C of baking oven, 24 is small
When after check its pliability, be adapted to cut with single-edge blade, it is standby；
2) Radix Astragali finished product bar, is cut into Radix Astragali root segment using dichotomy, takes each section of upper end and distal portion respectively
Flakiness is cut, section is dyed with phloroglucin-concentrated hydrochloric acid, the number of growth ring is observed, it is determined that actual growth year；
Wherein：The collocation method of phloroglucin is：Weigh 0.1g phloroglucin powder to be placed in drop bottle, add 10mL distillations
Water；Concentrated hydrochloric acid concentration is 37%；
3), the consistent root segment of step 2) upper and lower side growth ring number is no longer cut, is divided into respective level；Up and down
Hold growth ring number inconsistent, recycle dichotomy to be cut, untill growth ring number is consistent；
4) the consistent root segment of actual growth year, is classified as same grade, the wherein more growth year of growth ring number
Longer, respective level is higher.
Milkvetch Root is divided into different Radix Astragali root segments by method provided by the invention of grading, growth ring number it is consistent be classified as phase
Grade is answered, the wherein more growth year of growth ring number is longer, and respective level is higher.The inventive method is simple and easy to operate, solution
The problem of current Radix Astragali commercial grade of having determined can not react growth year, the scientific evaluation of Milkvetch Root resource quality is realized,
Classifying rationally for Milkvetch Root commercial specification grade is laid a good foundation.
