Abstract
The invention relates to a preparation method for the extract of Folium Dendrobium officinale. The preparation method comprises the following steps: subjecting fresh roots of Dendrobium officinale to preliminary screening for impurity removal and then cleaning the roots; soaking the cleaned fresh roots of Dendrobium officinale for 8 to 10 d; subjecting a soaking solution of the roots of Dendrobium officinale to high-temperature steaming for 24 to 48 h so as to obtain a concentrate; and adding ethanol into Dendrobium officinale having undergone high-temperature steaming and the concentrate, carrying out extraction at 100 DEG C and concentrating a filtrate so as to obtain the extract of the roots of Dendrobium officinale, wherein a weight ratio of the steamed Dendrobium officinale and the concentrate to ethanol is 1: 2 to 1: 5.
Description
Technical field
The present invention relates to a kind of preparation method of Herba Dendrobii leaf extract.
Background technology
Herba Dendrobii stem, sweet in the mouth are dried, be slightly cold.Return stomach, kidney channel, there is reinforcing stomach reg fluid, nourishing YIN and clearing away heat.Herba Dendrobii root,
It is not belonging to medicinal part at present, nor use as bread and cheese although yield is very big, but the huge iron sheet stone of current production rate
Dry measure used in former times root can only be made waste and process.
Inventor's research finds, Herba Dendrobii root and Herba Dendrobii medical material (stem), containing the same chemical composition of multiple types, also have portion
Function as classification.
Patent 103690795A discloses a kind of Herba Dendrobii root extract with hypotensive effect and purposes it is indicated that Herba Dendrobii root
Also there is Herba Dendrobii stem identical effectiveness, but in this patent documentation, extraction process mainly utilizes alcohol reflux, and at this
In technical scheme, mainly pass through to soak and high temperature steaming extracts, can get extract through ethanol concentration.
Content of the invention
Present invention aim at providing a kind of Traditional Chinese medicine fertilizer, soil quality can be improved, reducing the drug residue of soil.
In order to realize foregoing invention purpose, the present invention adopts technical scheme as follows：
A kind of preparation method of Herba Dendrobii root extract, comprises the steps of：
(1) fresh Herba Dendrobii root is cleaned after preliminary screening goes the removal of impurity；
(2) clean Herba Dendrobii root is soaked, the time is 8-10 days；
(3) soak of Herba Dendrobii root is carried out high temperature steaming 24-48 hour, obtain concentrated solution；
(4) Herba Dendrobii after high temperature steaming and concentrated solution add ethanol weight ratio for 1:2-1:Extract at 5,100 DEG C,
Filtrate is concentrated to give the extract of Herba Dendrobii root.
Herba Dendrobii and concentrated solution add ethanol weight ratio for 1:3.
The soak of Herba Dendrobii root carried out the high temperature steaming time for 48 hours.
The present invention compared with prior art has the advantages that：Mainly pass through to soak and high temperature steaming extracts, through ethanol concentration
Can get extract, whole operation process relatively simple it is easy to operation, and decrease the usage amount of solvent.
