Description
Technical field
The present invention relates to the discrimination methods of the sharp leaf roxburgh anoectochilus terminal bud of different planting.
Background technology
Roxburgh anoectochilus terminal bud (Anoectochilus roxburghii) is the plant of orchid family Anoectochilus Blume, is mainly distributed on China Fujian
Tai Area is perennial Precious, Rare, Endangered medicinal material.Roxburgh anoectochilus terminal bud has effects that clearing heat and cooling blood, expelling wind and removing dampness, cures mainly ephritis, bladder
The illnesss such as inflammation, diabetes, bronchitis, pediatric acute convulsion.Roxburgh anoectochilus terminal bud has higher medicinal health value, but wild resource is dilute
It lacks, currently on the market based on cultivation product, the strain of circulation mainly includes sharp leaf, big roundleaf, small roundleaf, red rosy clouds and TaiWan, China
Roxburgh anoectochilus terminal bud.Planting type is broadly divided into tissue cultures and plantation of burying, and tissue culture product are mostly the tissue-culture container seedling of 3~5 months, enter soil species
Plant product are mostly that the bottle seedling of 3~5 months is transplanted to the kind of regrowth 3~6 months in soil environment and plants seedlings.Different planting types pair
Active ingredient-polysaccharide of roxburgh anoectochilus terminal bud, the content of flavonoids are affected, and the planting type of tissue culture+plantation of burying is than simple tissue culture
Polysaccharide, flavones content higher, the implantation time that buries is longer, and the residual quantity of heavy metal, hormone and antibiotic is lower, but dead
Rate is also constantly soaring；Therefore not only quality is different for the roxburgh anoectochilus terminal bud of different planting, price also differs greatly.
At present, the research of China's roxburgh anoectochilus terminal bud quality standard is relatively weak, lacks unified product quality inspection standard.
Differentiate that the roxburgh anoectochilus terminal bud of different planting is limited only to judge by rule of thumb in the market, however 3 months bottle seedlings, 4 months bottle seedlings or 6
Difference between a monthly income soil species plants seedlings is not notable, the illegal businessman in part is caused directly to launch tissue-culture container seedling, with secondary
It substitutes the bad for the good, causes selling market chaotic, seriously hinder sound development and the popularization of roxburgh anoectochilus terminal bud industry.
Near-infrared spectrum technique (NIRS) is used as a kind of high-new analytical technology, with finding speed is fast, sample is lossless, does not disappear
The advantages that consuming chemical reagent.In recent years, near-infrared spectrum technique is gradually widely used in Chinese traditional medicine identification field, can quickly reflect
The kind of other Chinese medicine, mixes puppet, place of production etc. at the true and false.
A kind of easy, green, the method for the sharp leaf roxburgh anoectochilus terminal bud for accurately differentiating different planting need to be found.
Invention content
