With Rhizoma Kaempferiae glycosides for reference substance, adopt aluminum chloride determination of color total flavones, and with the extraction ratio of total flavones for performance assessment criteria, optimal screening total flavones extraction purification condition, and carried out effect experiment.
1. optimization for extracting condition
(1) amount of water is investigated
Take Asplenium trchomanes L. 111.1g and Radix cynanchi wilfordii 111.1g respectively, totally 3 parts, add various dose soak by water respectively 3 times, each 2 hours, with the extraction ratio of total flavones for operation index amount of water is on the impact of total flavones stripping.
As can be seen from the above results, adopt 8 times amount and 10 times of water gagings all can obtain good result, but in conjunction with manufacturing cost and energy consumption, let us preferably add 8 times of water gagings.
(2) extraction time is investigated
Take Asplenium trchomanes L. 111.1g and Radix cynanchi wilfordii 111.1g respectively, totally 3 parts, add 8 times amount soak by water respectively, each 2 hours, with the extraction ratio of total flavones for operation index extraction time is on the impact of total flavones stripping.
As can be seen from the above results, the extraction ratio of total flavones raises along with the increase of extraction time, but extract 4 times with extract the effect of 3 times without marked difference, for saving, we adopt 3 extractions man-hour.
(3) extraction time is investigated
Take Asplenium trchomanes L. 111.1g and Radix cynanchi wilfordii 111.1g respectively, totally 3 parts, add 8 times of soak by water respectively 3 times, with the extraction ratio of total flavones for operation index extraction time is on the impact of total flavones stripping.
As can be seen from the above results, the extraction ratio of different ageings to total flavones has a certain impact, in conjunction with the extraction ratio of man-hour and total flavones, we determine the combination that No. 2, employing is tested, and namely extract 3 times, 2 hours first times, second time 1.5 hours, 1 hour third time.
2. purification condition optimization
Prepared by extract: take each medical material, add 8 times of soak by water 3 times, 2 hours first times, second time 1.5 hours, 1 hour third time, collecting decoction, filter, filtrate is concentrated into the clear paste that relative density is 1.20 (80 DEG C), is divided into 2 parts, carry out purification in different ways respectively, investigate purification condition to the impact of the total flavones rate of transform.
Method one: clear paste is cooled to 40 DEG C, adds 2 times amount ethanol, and mixing, places 24 hours, get supernatant, filters, and reclaim ethanol, being concentrated into relative density is 1.25 (80 DEG C), drying under reduced pressure, measures content.
Method two: treat that cream is chilled to 40 DEG C, adds equivalent n-butanol extraction 3 times, and merge n-butyl alcohol liquid, decompression and solvent recovery to relative density is the clear paste of 1.25 (80 DEG C), drying under reduced pressure, measures content.
As can be seen from the total flavones rate of transform above, the purification effect of purification process two ratio method one is good, and it is good that effective ingredient retains comparatively first method, still selected purification process be: add equivalent n-butanol extraction 3 times.
3. preparation technology's checking
Take Asplenium trchomanes L. and each 222.2g of Radix cynanchi wilfordii, mixing, totally 3 parts.Add 8 times of soak by water 3 times, 2 hours first times, second time 1.5 hours, 1 hour third time, collecting decoction, filters, filtrate is concentrated into the clear paste that relative density is 1.20 (80 DEG C), treat that cream is chilled to 40 DEG C, add equivalent n-butanol extraction 3 times, merge n-butyl alcohol liquid, decompression and solvent recovery to relative density is the clear paste of 1.25 (80 DEG C), drying under reduced pressure, pulverizes, and measures general flavone content and Rhizoma Kaempferiae glycosides content.
