Technical field
The present invention relates to the technical fields of Chinese medicine processing, and in particular to a kind of processing method of Herba Dendrobii and is promoted folded
The technology of the method for sheath dendrobium nobile ethanol soluble extractives content and dendrobium polysaccharide content.
Background technique
Herba Dendrobii is the stem of the plant Herba Dendrobii Dendrobium denneanum Kerr. of orchid family Dendrobium, mainly
It is distributed in the ground such as Sichuan Province, China west and south, Guangxi southwest to the northwestward, South of Guizhou, southeastern Yunnan.At present in Sichuan Province
Leshan Jiajiang County is widely cultivated and hyoscine." Sichuan Province's prepared slices of Chinese crude drugs concocted specification " version (P375-376) in 2015 records it
It is used as medicine as dendrobium nobile, there is the effect of " reinforcing stomach reg fluid, nourishing Yin and clearing heat ".The main component of Herba Dendrobii is dendrobium polysaccharide, dendrophnol
Deng having the effects that reduce blood glucose, antitumor, anti-oxidant, clinic is mainly used for type-2 diabetes mellitus, diabetic eye diseases, chronic shallow
Table gastritis and the adjuvant treatment of kinds of tumors etc..
Processing method is the Herba Dendrobii inherent quality of different processing method production an important factor for influencing prepared slice quality
There were significant differences with mouthfeel is taken.Common processing method has infusion method, slice method of making herbs dry gradually in the shade, slice oven drying method, Dan to shine method, Dan system
The problem of comminuting method etc., these methods cut both ways in practical applications, can not be fully solved Herba Dendrobii processing:
Infusion method: being traditional habitat processing method, acquires fresh Herba Dendrobii, root, leaf is removed, with clear water or plant ash water logging
It steeps 2-3 months, changes within during which every 2-3 days a water, leaf sheath gradually can slowly fall off in soaking process.It is complete to Herba Dendrobii leaf sheath
It after falling off, pulls out, dry, as net Herba Dendrobii medicinal material.This method advantage be Herba Dendrobii be difficult to the leaf sheath eliminated can be natural
It falls off, compares less manpower.But process time is too long, and water resource waste is serious, and Herba Dendrobii is impregnated with a large amount of water for a long time, medicinal material
In water soluble ingredient loss it is serious, the Herba Dendrobii being processed into is second-rate.
Slice method of making herbs dry gradually in the shade: taking Herba Dendrobii fresh goods, removes root, leaf and leaf sheath, cuts inclined tab after cleaning, and sets at shady and cool ventilation certainly
So dry.This method advantage be it is easy to operate, required equipment is simple.But leaf sheath can not be eliminated, in the film quality leaf sheath of Herba Dendrobii
Wax component can hinder the evolution of moisture in stem, and the process time that dries in the shade is long, generally require 5-7 days, because in Herba Dendrobii
Plant enzyme do not inactivate, plant cell will continue to breathe, lead to the loss of Herba Dendrobii sugar, the extract of Herba Dendrobii and
Dendrobium polysaccharide reduces.
Dan shines method: being the processing method that " Guizhou Province's prepared slices of Chinese crude drugs concocted specification " records.The dendrobium nobile adopted back is removed into impurity,
It is put into 85 DEG C of hot water and scalds 1-2min, pick up, be exposed to the sun, when shining to soft body, with the hands rubbed when shining, it will leaf of the packet on stem branch
Sheath is cleared, 1 time a day, until foot is dry.This method advantage is the plant enzyme scalded in inactivation Herba Dendrobii by water, can reduce sugar
Consumption, is conducive to the reservation of effective component.But it is relatively high to weather requirement, it can not such as be exposed to the sun in time, medicinal material is easily rotten.And it is logical
The mode drying time for crossing solarization is also required to 2-3 days, and sugar can ferment point in the Herba Dendrobii in half dry and wet state for a long time
It solves and rancid, the pharmaceutical activity of Herba Dendrobii is caused to decline, clinical effect reduces.
Slice oven drying method: taking Herba Dendrobii fresh goods, removes root, leaf and leaf sheath, and inclined tab, 60 DEG C of drying are cut after cleaning.This method
Advantage be it is simple and efficient, drying time can be reduced to 8-10h.But the non-medicinal effects such as can not eliminate leaf sheath, Herba Dendrobii
Wax component in film quality leaf sheath can hinder the evolution of moisture in stem, cause drying time longer.And the plant in Herba Dendrobii
Enzyme does not inactivate, and plant cell will continue to breathe, and leads to the loss of Herba Dendrobii sugar.
Dan fine powder method: being the method that " Sichuan Province's prepared slices of Chinese crude drugs concocted specification " version in 2015 is recorded.Annual November is to secondary
The stem of 2 months years harvesting, 3 years leaf abscissions of growth.Root, residual leaf, leaf sheath, the impurity such as silt are removed, with 10 times of amount water Dan 5min,
It dries, is baked when rubbing with the hands, until rubbing net leaf sheath with the hands, be drying to obtain Herba Dendrobii medicinal material, by medicinal material cleaning, drying, be ground into fine powder.This
Method process can will foreshorten to 3-5 days, obtained Herba Dendrobii quality is more steady process time with respect to traditional processing
It is fixed, but rub the processing link of net leaf sheath with the hands, it takes a long time, and can only be by manual operations, labor intensity is larger, and is difficult leaf sheath
Removal is clean.Dan system can make the plant enzyme-deactivating in Herba Dendrobii, during Dan system, Herba Dendrobii water soluble ingredient part ease
It loses, causes the pharmacological action and bioactivity decline of Herba Dendrobii.

There were significant differences for extract.Processing recovery rate and finished product extract content is comprehensively compared, acquisition in annual November to next year 2 months is most
The season of the excellent fresh Herba Dendrobii of harvesting.
Analysis: Herba Dendrobii belongs to herbaceos perennial, starts annual March that axillary bud will be sprouted on stem, and grow
Aerial root becomes seedling.It germinates and takes root and cauline leaf offer nutrient is provided, the nutrition of Herba Dendrobii medicinal effects stem can be consumed,
So the Herba Dendrobii of acquisition in March, after being processed into finished product, recovery rate and extract content are substantially lower than the harvesting of 2 months
's.Annual November starts Herba Dendrobii old leaf and starts shedding off, and nutritional ingredient starts to accumulate in stem, until 2 month of next year, is
The peak of extract content and recovery rate, therefore annual 2 months November to next years acquisition is the season of the optimal fresh Herba Dendrobii of harvesting,
This winter traditional with the place of production adopts habit and is consistent.
3) the preferred of process time is steamed
Method: the net Herba Dendrobii stem of blanking decontamination is divided into 6 groups, and every group of 1kg is steamed with electric heating steaming tank respectively

Conclusion: steaming time is advisable with 15-20min.Water consumption for immersion is advisable with 20kg.
Analysis: steaming time is directly related with the qualitative character of Herba Dendrobii and stranding net leaf sheath time.Steaming time is too short,
Herba Dendrobii stem fails to steam thoroughly completely, then can not rub net core with the hands, and steaming time is too long, and Herba Dendrobii stem is soft rotten, and leaf sheath dissipates
It falls and is mixed with stem, can not also eliminate leaf sheath, and qualitative character is also poor, therefore steaming time is advisable with 15-20min, skill
Herba Dendrobii stem can be made to steam completely thoroughly, and will not be steamed soft rotten.To make stem and leaf sheath while quenching and shrinkage amplitude is different, from
And the purpose of energy delamination, it should ensure that soaking time as short as possible, soaking time are advisable in 1min, this just needs bigger
Cold water usage.In order to avoid impregnating the loss for the extract that cold water generates, it is also desirable to soaking time as short as possible, and reach
Cold water usage as few as possible under the premise of quenching effect.According to experimental result, water consumption for immersion is with 20 times of fresh Herba Dendrobii weight
It is advisable, can achievees the purpose that be Herba Dendrobii quenching in 1min.
4) drying time and temperature is preferred
Method: removing 4 groups of Herba Dendrobii of decontamination, and every group of 1kg steams 15min with electric heating steaming tank, be then immersed in 20kg
In cold water, surface moisture is dried in taking-up, with the net leaf sheath of hand rubbing, is layered in pallet, sets respectively dry in heated-air circulation oven.It is dry
Temperature is respectively set as 50 DEG C, 60 DEG C, 70 DEG C, 80 DEG C, and oven temperature reaches set temperature and starts timing, and every 15min, which is opened, to be taken out

| Dry 60min- water content | 51.4% | 39.7% | 33.4% | 30.6% |
| Dry 90min- water content | 44.6% | 27.2% | 18.6% | 16.5% |
| Dry 120min- water content | 37.3% | 19.8% | 9.2% | 11.8% |
| Dry 150min- water content | 30.5% | 12.5% | - | - |
| Dry 180min- water content | 24.7% | 9.6% | - | |
| Dry 210min- water content | 19.5% | - | ||
| Dry 240min- water content | 14.8% | |||
| Dry 270min- water content | 11.9% |
Conclusion: drying temperature is set as 60-70 DEG C, and drying time is advisable for 2-3h.
Analysis: it in order to reduce the influence that sugar caused by half dry and wet state of Herba Dendrobii ferments to Herba Dendrobii quality, answers
Herba Dendrobii is set to reach safety moisture content in the time as short as possible, Herba Dendrobii drying time and temperature are directly related, therefore answer
Higher temperature is set to shorten drying time.The excessively high gelatinization that can cause polysaccharide and amylum body in Herba Dendrobii of temperature, causes medicine
The loss of active constituent is managed, Herba Dendrobii starch gelatinization temperature is at 85 DEG C or more, therefore drying temperature is usually no more than 80 DEG C.50℃
Temperature condition, Herba Dendrobii can be uniformly dehydrated, but drying time is longer.80 DEG C of temperature condition, Herba Dendrobii can be rapidly
Dehydration, but after the rapid draing of surface, the evolution of central part moisture has been obstructed instead, to keep drying time further
Shorten.Therefore 60-70 DEG C is the reasonable drying temperature of comparison, Herba Dendrobii can be dried to safety moisture content by 2-3h.
In conclusion " step 3) steam in steaming time be 15-20min, the water temperature of cold water is 2-10 DEG C, when immersion
Between be 1-2min, water is 15-25 times of Herba Dendrobii weight, dry in 60-70 DEG C of drying temperature, drying time 2-4h "
