Abstract
A method for preparing raw medicinal material by culturing the stem apexes of Dendrobium officinale in large scale includes obtaining aseptic culture line of said stem apex, and induced culture. Its product can improve non-specific immunity and cell immunity.
Description
Technical field
The invention belongs to technical field of bioengineering.Be specifically related to a kind of method that the dendrobium candidum Shoot Tip Culture is produced medicinal material of using.
Background technology
Dendrobium (Dendrobium) is the big genus of of the orchid family, comprises kind more than 1600
[1]Plant, China has 63 kinds approximately, wherein hyoscine has a kind more than 30, mainly contain dendrobium loddigesii Rolfe (D.loddigesii), stem of Eyeshaped Dendrobium (D.fiubriatum), dendrobium candidum (D.officinale), HERBA DENDROBII (D.chrysanthum) and HERBA DENDROBII (D.nobile), dendrobium candidum is the most precious person wherein.The traditional Chinese medical science is thought the effect that the stem of noble dendrobium has replenishing the vital essence and removing heat, promotes the production of body fluid to quench thirst and makes eye bright and keeps fit, and modern medicine finds that the stem of noble dendrobium contains multiple alkaloid, polysaccharide and amino acid, has the immunity of raising, suppresses thrombosis, suppresses tumour and function in delaying senility.
Dendrobium plant natural propagation rate is very low, and people excessively excavate in addition, and its resource is day by day exhausted.As nourishing Yin and clearing heat simply rare Chinese medicine, increasing to the demand of the stem of noble dendrobium especially dendrobium candidum both at home and abroad in recent years, though the cultivation of stem of noble dendrobium research is a lot, because stem of noble dendrobium growth is very slow, present cultivation far can not be satisfied the demand in market.Therefore, the tissue culture paid more and more attention of relevant Dendrobium plant, the research of relevant this respect increases gradually, these researchs mainly concentrate on from different explants---test-tube plantlet---and cultivate this approach, though the research of some ball stems cultivations and callus culture is arranged, and large-scale production is report not.
Summary of the invention
Technical problem to be solved by this invention is to be to utilize plant tissue culture technique at the problems referred to above, by preparation, screening and the cultivation of dendrobium candidum hormone autotrophic type stem apex, thus the medicinal part of this rare medicinal herbs of large-scale production---stem apex.
Main contents of the present invention are as follows:
A kind of dendrobium candidum Shoot Tip Culture is, it is characterized in that:
1. be material with wild dendrobium candidum (Dendrobium officinale) terminal bud, medical ethanol with 70% soaks 1min, be transferred to subsequently and carry out surface sterilization in 10% aqueous sodium hypochlorite solution, be seeded on the MS+NAA 1.5mg/L+KT 0.2mg/L solid culture medium that high-temperature sterilization crosses, in temperature is 25 ± 1 ℃ of following illumination cultivation, the pH value is to get the dendrobium candidum stem apex after 5.8,60 days.
With resulting stem apex cultivate on the same medium stable after, reduce hormone dosage gradually, continue to cultivate, per 4～5 months subcultures once, reduce to zero until hormone, the screening of inducing through about 3 years obtains stable dendrobium candidum Shoot Tip Culture system, and profile is between ball stem and seedling.
3. more different carbon sources, nitrogenous source and phosphorus source be to the result of stem apex growth and polysaccharide, total alkaloid content influence, and simultaneously in order to reduce cost, our screening has also designed the N of improvement
6Medium is a minimal medium, and its composition sees Table 1.
4. on this medium, our research and design best condition of culture, illumination 1500-2500lux, 20～28 ℃ of temperature.

EmbodimentEmbodiment 1: be used for the cultivation of large-scale culture seed stem apex
(1) forms (seeing Table 1) by culture medium prescription of the present invention, the preparation medium.Measure the pH value with pH meter, and regulate the medium pH value in the 5.6-5.8 scope with the HCl of 1N and the NaOH of 1N, seed culture medium must add 0.8% agar.Be sub-packed in then in the blake bottle, every bottle of 50～60ml carries out autoclaving, and pressure is 1.0-1.2Kg/cm
2, the time is 15-25 minute.
(2) selecting well-grown, color and luster stem apex dark green, that be of moderate size is provenance, is inoculated in superclean bench in the above ready solid culture medium and cultivates, and inoculum concentration (in fresh weight) is every bottle of 3g.Postvaccinal blake bottle is put into the cultivation of culturing room, and condition of culture is: illumination 1500-2500lux, 20～28 ℃ of temperature, per February subculture once.
(3) during successive transfer culture, select excellently, dispel the color jaundice, dysgonic stem apex selects good stem apex to continue to cultivate, in case find whole delayed growth, active constituent content reduces, then from wild dendrobium candidum seed selection again.Embodiment 2: the large-scale culture of dendrobium candidum stem apex
(1) forms (seeing Table 1) by culture medium prescription of the present invention, the preparation medium.Measure pH value with pH meter, and with the NaOH adjusting medium pH value of the HCl of 1N and 1N in the 5.6-5.8 scope, pack in the homemade blake bottle that has an absorbent cotton, every bottle of 50～60ml carries out autoclaving, pressure is 1.0-1.2Kg/cm
2, the time is 15-25 minute.
(2) select well-grown seed stem apex, by every bottle of 4g (in fresh weight) inoculation, the inoculation back moves into to cultivate in the greenhouse and cultivates, and uses natural lighting, when light is too strong, shelters from heat or light the employing measure of heating during 20 ℃ of temperature less thaies with the sunshade net.When treating that culture fluid uses up, stop cultivating or fluid infusion continuation cultivation according to growing way.Be one-period general March, and every bottle can be produced dried dendrobium candidum stem apex 2g, and a greenhouse of 500 square metres can be produced per year more than the dendrobium candidum stem apex dry weight 400Kg.Embodiment 3: the main active ingredient of dendrobium candidum stem apex and the comparison of wild dendrobium candidum
(1) after measured, the total alkaloid content that dendrobium candidum is cultivated stem apex reaches 261.3 μ g/gD.W. (this chamber is measured), far above wild dendrobium candidum 160.0 μ g/gD.W. (this chamber is measured).
(2) total polysaccharides (this chamber is measured) content is suitable with wild dendrobium candidum, is respectively 119.9mg/gD.W. and 122.4mg/gD.W..
(3) the main amino acid content of stem apex (Shanghai Organic Chemistry Institute, Chinese Academy of Sciences's mensuration) all be wild dendrobium candidum (Shanghai Organic Chemistry Institute, Chinese Academy of Sciences's mensuration) 2-5 doubly.
(4) essential element content (being measured by Institute of Analysis of Shanghai Communications University) is except that the macroelement stem apex is higher, the no significant difference of trace element.
(5) we have done the sequence comparison of matK gene in addition, find that cultivation stem apex and this dna homolog of wild dendrobium candidum are 99%, and the stem apex in 5 years of successive transfer culture is 100% with the autoploidy of the stem apex of newly inducing.Embodiment 4: cultivate stem apex and wild dendrobium candidum immunization relatively 1. experiment materials, 1.1 medicines and reagent
