Description
Technical field
The present invention relates to borneol camphor tree technical field more particularly to a kind of extraction methods of borneol camphor tree leaf crab apple tablet crude extract.
Background technique
Borneol camphor tree is both rare rare medicinal material and fine perfumery, is also important industrial chemicals, there is plant gold
Good reputation, borneol camphor tree originates in Indonesia Sumatra island, and the natural borneol perfume (or spice) tree tree root on Indonesia Sumatra island is once borneol
Main source, but due to long-term transition fell closely exhaustion.Borneol is recorded in the Northern and Southern Dynasties earliest, has nearly bimillennium to go through away from the present
History, borneol is referred to as natural borneol in the classic of TCM, because of great transdermal function, is attributed to aromatic and inducing resuscitation medicinal material.For mentioning
It taking in borneol camphor tree leaf piece for crude extract, existing extractive technique is typically all to carry out what purification used to substance in blade, and one
As complicated operation, be not suitable for the extraction of crude extract in borneol camphor tree leaf piece, it is therefore desirable to a kind of borneol camphor tree leaf crab apple tablet crude extract
Extraction method carrys out meet demand.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of borneol camphor tree leaf piece proposed slightly mentions
The extraction method of object.
To achieve the goals above, present invention employs following technical solutions:
The extraction method for designing a kind of borneol camphor tree leaf crab apple tablet crude extract, includes the following steps:

S2, the borneol camphor tree leaf piece after cleaning is spread out in great circle dustpan, and placed in the cool, naturally dry borneol
Moisture on camphor tree blade surface, and during drying, it needs to stir borneol camphor tree leaf piece 2-5 times；
S3, it borneol camphor tree leaf piece after natural drying is placed in disintegrating apparatus crushes 3-5 minutes, then take out spare；
S4, smashed borneol camphor tree leaf piece is placed in a reservoir, and petroleum ether solvent is added into container, it is to be ensured that stone
Oily ether solvents can completely flood borneol camphor tree leaf piece, and container is placed in water-bath and carries out heating water bath, allow in container
Constant temperature be maintained at 40-80 degree, impregnate 24-48 hours, then pull borneol camphor tree leaf piece out, petroleum ether solvent remains in
In container；
S5, a new container is separately taken again, new petroleum ether solvent is poured into new container, then will pull out in step S4
Borneol camphor tree leaf piece be put into new container, continuation is impregnated according to the method in step S4, and repetitive operation 3-6 times；
After S6, last time are impregnated, remaining borneol camphor tree leaf piece impurity is pulled out, and drain borneol camphor tree leaf completely
Petroleum ether solvent on piece impurity, will impregnate the petroleum ether solvent used every time and merge can be obtained borneol camphor tree leaf piece
Crude extract.
Preferably, in step sl, the place of production of the borneol camphor tree of picking is in Hunan Province's Huaihua City, the borneol camphor tree leaf of picking
Piece will guarantee the case where blade is not damaged by worms it has to be ensured that bright-colored, the blade not turned to be yellow.
Preferably, in step sl, the specific steps of borneol camphor tree leaf cleaning are as follows: clear water is poured into container first,
Borneol camphor tree leaf piece is poured into clear water again, and is divided with clean stirring rod according to the 5-10 that is stirred of a direction gently
Then clock pulls borneol camphor tree leaf piece out, replace clear water, then repeat the above steps and clean 3-6 times to borneol camphor tree leaf piece.
Preferably, in step s3, after borneol camphor tree leaf piece crushes, it is to be ensured that the borneol camphor tree leaf piece whole quilt in disintegrating apparatus
It takes out, avoids the waste of borneol camphor tree leaf piece.
Preferably, in step s 4, during immersion, using clean stirring rod in container petroleum ether solvent and dragon
Brain camphor tree leaf piece stirs 4-7 times, and stirring continues 3-8 minutes every time.
A kind of extraction method of borneol camphor tree leaf crab apple tablet crude extract proposed by the present invention, beneficial effect are: the present invention passes through dipping
