Abstract
The present invention provides a kind of purification process that tigogenin is extracted from sisal dregs, is the tigogenin crude product that will be extracted from sisal dregs, is recrystallized with hexamethylene and alcohol mixed solvent, centrifuges, obtains tigogenin sterling.The present invention changes traditional method recrystallized with modes such as ethanol, and uses hexamethylene and alcohol mixed solvent to recrystallize, and product purity can reach more than 93%.
Description
Technical field
The present invention relates to tigogenin, more particularly to a kind of purification process that tigogenin is extracted from sisal dregs.
Background technology
Tigogenin, also referred to as Tigogenin, sisalagenin etc., are the base stocks of synthesizing steroid hormone medicine, plain
There are " medical gold " and the title of " hormone is female ".The downstream product monoene produced using tigogenin, can synthesize his rice again
More than the 120 kinds of hormone medicines such as pine.Tigogenin is also widely used for the industries such as food, cosmetics and animal husbandry, is biological doctor
Medicine chemical field is most universal, most important basic material.It is more universal using sisal dregs extraction tigogenin.But the prior art
Mostly isolated and purified with ethyl alcohol recrystallization, generally require three times more than recrystallize, but product purity be extremely difficult to 90% with
On.As disclosed in Chinese patent " a kind of method for extraction tigogenin of squeezing the juice from sisal dregs "(CN103087143A), it is purified
Tigogenin in thick saponin is extracted using hot ethanol, filtering, through being concentrated in vacuo, standing, is collected by centrifugation saponin crystal, heated
Tigogenin finished product is obtained after drying.Its tigogenin extracted has good quality, less energy consumption, technique is simple, the rate of recovery is high, section
Can be environmentally friendly the advantages that, but do not refer to product purity is how many.
The content of the invention
It is an object of the invention to provide a kind of purification process that tigogenin is extracted from sisal dregs, it can be effectively improved
Product purity.
Embodiment of the present invention is:A kind of purification process that tigogenin is extracted from sisal dregs, is by from sisal dregs
The tigogenin crude product of middle extraction, is recrystallized with hexamethylene and alcohol mixed solvent, is centrifuged, is obtained tigogenin sterling.
Embodiment as an optimization, the matter of tigogenin crude product and hexamethylene and alcohol mixed solvent during the recrystallization
Amount proportioning is 1:8~12;More optimize, tigogenin crude product is 1 with the quality proportioning of hexamethylene and alcohol mixed solvent:
1。
Embodiment as an optimization, the temperature of the recrystallization is 70-80 DEG C.The temperature of the recrystallization more optimized is
75℃。
Embodiment as an optimization, the quality proportioning of the hexamethylene and ethanol is 1:0.5~1.5.More optimize
It is that the quality proportioning of the hexamethylene and ethanol is 1:1.
The present invention changes traditional method recrystallized with modes such as ethanol, and uses hexamethylene and ethanol to mix
Solvent recrystallization, product purity can reach more than 93%.
Embodiment
The embodiment of the present invention is given below, the present invention will be described in detail.
Embodiment 1:A kind of extraction of tigogenin and purification process, specific method and step are as follows:
(1)The sisal dregs for removing fiber are added into water, are fermented 10~20 days, it is dry;
(2)Dry sisal dregs are put into concentration as in 15~25% aqueous hydrochloric acid solutions, with being steam heated to temperature 150~200
DEG C, and in 2.5~3.5kg/cm2When hydrolysis 2.5~3.5 is small under pressure;
(3)Press filtration, filter residue add lime calcification, then press filtration, filter residue are dried, obtains hydrolysate;
(4)It is 95% alcohol steep by hydrolysate purity, 60~100 DEG C, 50~80min of time of extraction temperature, feed liquid weight ratio
1:15~25;
(5)Leaching liquor is concentrated into postcooling to room temperature, crystal centrifugation is dried, obtains tigogenin crude product;
(6)By tigogenin crude product hexamethylene and alcohol mixed solvent recrystallization purification, centrifuge, it is pure to obtain tigogenin
Product.75 DEG C of recrystallization temperature, tigogenin crude product are 1 with the quality proportioning of hexamethylene and alcohol mixed solvent:10, hexamethylene and
The quality proportioning of ethanol is 1:1.Second alcohol concentration≤95% used.
Tigogenin product purity 95.16% obtained by the above method.
Embodiment 2:A kind of tigogenin purification process, by 1 step of embodiment(5)The tigogenin crude product hexamethylene of gained
Alkane and alcohol mixed solvent recrystallization purification, centrifuge, obtain tigogenin sterling.80 DEG C of recrystallization temperature, tigogenin is thick
Product are 1 with the quality proportioning of hexamethylene and alcohol mixed solvent:8, the quality proportioning of hexamethylene and ethanol is 1:0.5.
Tigogenin product purity 93.08% obtained by the above method.
Embodiment 3:A kind of tigogenin purification process, by 1 step of embodiment(5)The tigogenin crude product hexamethylene of gained
Alkane and alcohol mixed solvent recrystallization purification, centrifuge, obtain tigogenin sterling.Recrystallization temperature:70 DEG C, tigogenin is thick
Product are 1 with the quality proportioning of hexamethylene and alcohol mixed solvent:12, the quality proportioning of hexamethylene and ethanol is 1:1.5.
Tigogenin product purity 93.32% obtained by the above method.
Embodiment 4:A kind of tigogenin purification process, by 1 step of embodiment(5)The tigogenin crude product ethanol of gained
Recrystallization purification, centrifuges, obtains tigogenin sterling.75 DEG C of recrystallization temperature, tigogenin crude product and ethanol quality proportioning
For 1:10, second alcohol concentration≤95%.
Tigogenin product purity 89.86% obtained by the above method.
From above-described embodiment as can be seen that the present invention is recrystallized using hexamethylene and alcohol mixed solution, product is pure
Degree can reach more than 93%, and be recrystallized using ethanol under the conditions of same as Example 1, and product purity is only
