Abstract
The invention discloses a flavone extracting technology of plant effective component based on discarded bamboo, which comprises the following steps: predisposing bamboo leaf; extracting through heating in the water; condensing; extracting through positive butanol liquid; recycling solvent; removing metal through flocculation; spraying; drying.
Description
Technical field
The present invention relates to a kind of extraction process of effective ingredients in plant, relate in particular to a kind of peasant of utilization and cut down the leaf of bamboo that the bamboo wood process abandons method for the raw material production Folium Bambosae flavone.
Background technology
The leaf of bamboo has long edible and medicinal history in China, is the famous heat-clearing and detoxicating drug of the traditional Chinese medical science, also be the 3rd batch of (1998) promulgation of China be food be again the natural phant of medicine.Contained functional factor mainly is a flavone glycoside in the leaf of bamboo; a large amount of scientific research and experimental results show that: Folium Bambosae flavone has good Green Tea Extract; anti-oxidant and activity of fighting against senium; can significantly strengthen the immunity function of human body; regulate lipid metabolism; the protection cardiovascular and cerebrovascular; antifatigue; antibiotic; antiviral; skin care; whiten; and do not contain any objectionable constituent and antinutritional factor; be a kind of very good natural biological flavones new resources; disclosed application number is 98104564.2 Chinese invention patent applications---the production method of extracting flavonoid compound extract or pulvis from the leaf of bamboo provides a kind of method of producing Folium Bambosae flavone; this method is used a large amount of ethanol in extraction; and can't remove some beavy metal impurities in the extract, can't solve the difficult problem of heavy metals exceeding standard in the plant milk extract.
Summary of the invention
The object of the present invention is to provide a kind of production method of from the leaf of bamboo, extracting Folium Bambosae flavone, overcome the deficiencies in the prior art, require to have the advantage that technology is simple, easy to operate, facility investment is few, extract yield height, good product purity, non-environmental-pollution.
The objective of the invention is to realize by following technical scheme:
A kind of production method of extracting Folium Bambosae flavone from the leaf of bamboo comprises the steps:
1 with stand-by after the fresh leaf of bamboo collection clean dry;
2 put into tank with the leaf of bamboo, add 6～10 times water of leaf of bamboo weight, are heated to 80 ℃～100 ℃, and the time length is 0.5---1.5 hour, and the effective constituent in the leaf of bamboo fully is dissolved in the water, leaches solution for later use;
3 become medicinal extract with above-mentioned solution concentration, and thickening temperature is 50 ℃～80 ℃, concentrate back medicinal extract and heavily be the leaf of bamboo heavy 20%～40%;
4 further purify above-mentioned medicinal extract by the propyl carbinol liquid-liquid extraction, and extraction agent is a propyl carbinol, water and organicly be in a ratio of 1: 2～4, stirred about 0.5-1.5 hour, abundant mixing, static more than 4 hours after, separating and extracting liquid, stripped residue for the first time, again add propyl carbinol and stir extraction, static more than 4 hours after, separating and extracting liquid, it is stand-by to merge twice extraction liquid, adopts concentrating under reduced pressure to reclaim the solvent recycling;
5 extracts become Folium Bambosae flavone medicinal extract with an amount of water dissolution, add flocculation agents such as albumen (gelatin, whey, egg white), alcohol and fully stir, and leave standstill 2-8 hour, and it is stand-by to get supernatant Folium Bambosae flavone medicinal extract liquid;
6 are spray dried to powdery with above-mentioned feed liquid in spray tower, 160～180 ℃ of control inlet temperature, 85～95 ℃ of air outlet temperatures.
Adopting the present invention to produce its advantage of Folium Bambosae flavone is:
1, Folium Bambosae flavone of the present invention is not to be raw material with the leaf of bamboo of direct harvesting, but with the agricultural Litter of cutting down the bamboo wood process of bamboo, sort out collection, drying treatment, can improve the comprehensive utilization ratio of bamboo grove greatly like this, increase bamboo farming income, the dry leaf of bamboo is convenient to the transportation preservation simultaneously, and enterprise can be produced throughout the year, reduces the raw materials cost of enterprise.
2, Folium Bambosae flavone production method of the present invention, the extraction solvent that is adopted is a water, does not add any other auxiliary material, can at utmost keep the security of the finished product like this, also can reduce the solvent use cost of enterprise simultaneously greatly, reduces the pollution to environment.
3, the extractant of Folium Bambosae flavone production method use of the present invention, this is as foodstuff additive, and safety performance is good, improves the concentration of aqueous phase solution simultaneously, has reduced the loss of extractant, has improved plant factor.
4, flocculent precipitation of the present invention can effectively solve the difficult problem of heavy metals exceeding standard in the plant extract, according to mensuration, the Folium Bambosae flavone that obtains 〉=24%, lead≤2mg/kg, arsenic≤1mg/kg, product meet the requirement of GB16740-1997 health care (function) food universal standard fully.
5, spray-drying process of the present invention can further be removed the dissolvent residual in the product, detects propyl carbinol by the GB/T5009.48-2003 method and remains in below the inspection limit.
Therefore, a kind of production method of extracting Folium Bambosae flavone from the leaf of bamboo of the present invention has the advantage that technology is simple, easy to operate, facility investment is few, extract yield height, good product purity, non-environmental-pollution.
