Abstract
The present invention relates to crop extractive technique fields, extracting method and its extract and application more particularly, to flavonols component in a kind of roundpod jute leaf.The extracting method of flavonols component in the roundpod jute leaf includes the following steps: to carry out refluxing extraction to roundpod jute leaf using the solution of alcohol-containing as extracting solution.Extracting method of the present invention, can isoquercitin, Quercetin and Kaempferol of the depth extraction into roundpod jute leaf, high income, simple process, mild condition;Also, the extract extracted using extracting method of the present invention is acted synergistically by the isoquercitin of specific quantity, Quercetin and Kaempferol three, ability and tyrosinase activity inhibiting effect with excellent removing free radical.

The ability of free radical all has preferable elimination effect to hydroxy radical, DPPH free radical and ultra-oxygen anion free radical, is function
It can property food, beauty product offer basis.
In order to realize above-mentioned purpose of the invention, the following technical scheme is adopted:
The extracting method of flavonols component, includes the following steps: in roundpod jute leaf
Refluxing extraction is carried out to roundpod jute leaf using the solution of alcohol-containing as extracting solution.
The present invention extracts roundpod jute leaf using the solution of alcohol-containing as extracting solution, mainly in alcohol dissolution roundpod jute leaf
Isoquercitin, Quercetin and Kaempferol, when avoiding extracting using pure water, water-soluble substances are largely dissolved out, caused by extract
Object complicated component, purification difficult, and the problem that activity is relatively low.
Preferably, in the extracting solution, the volume fraction of alcohol is 60-90%.
In the present invention, in extracting solution, the volume fraction of alcohol is particularly significant for extraction process.When the volume fraction of alcohol is upper
It states in range, dissolution can be avoided water-soluble while guaranteeing to extract isoquercitin in roundpod jute leaf, Quercetin and Kaempferol
Substance keeps activity relatively low and increases purification difficulty.If the volume fraction of alcohol is too low, water-soluble substances are dissolved out in extract
Excessively, extract activity is relatively low, and causes difficulty to purification;Substance if the volume fraction of alcohol is excessively high, in extract
Structure is more easily damaged, so that active material is reduced.
Also, said extracted liquid is used, the isoquercitin, Quercetin and Kaempferol of specific quantity, three association can be extracted
There is different effects with cooperation.
Preferably, the solution of the alcohol-containing is the aqueous solution of alcohol-containing.
Preferably, the alcohol includes methanol and ethyl alcohol.It is furthermore preferred that the alcohol is methanol.
Dissolution isoquercitin, Quercetin and Kaempferol can be taken into account using methanol and ethyl alcohol, dissolve out a certain amount of isoquercitrin
After element, Quercetin and Kaempferol, triple interaction, the inhibition for maximizing the effect and tyrosinase of removing free radical is made
With.
Wherein, using the aqueous solution of the methanol of the score containing certain volume as extracting solution, the extract extracted is to certainly
It is excellent by the Scavenging activity of base and significant to the inhibiting effect of tyrosinase.
Preferably, the extracting solution is the aqueous solution for the methanol that volume fraction is 70%.
Using said extracted liquid, roundpod jute leaf is extracted, can extract to obtain the isoquercitin of specific quantity, Quercetin and
Kaempferol, three's synergistic effect, so that reachable to the Scavenging activity of hydroxy radical, ultra-oxygen anion free radical and DPPH free radical
To 97.61%, 62.66% and 88.15%.
Preferably, the extracting solution is the aqueous solution for the methanol that volume fraction is 90%.
Using said extracted liquid, roundpod jute leaf is extracted, the isoquercitin, the quercitrin that obtain specific matching amount can be extracted
Element and Kaempferol, three's synergistic effect is best to the inhibiting effect of tyrosinase activity, can reach 85.56%.
Preferably, the ratio of the roundpod jute leaf and extracting solution be 1g ﹕ (20-40) mL, preferably 1g ﹕ (25-35) mL, it is more excellent
It is selected as 1 ﹕ 30mL.
Preferably, the temperature of the refluxing extraction is 70-90 DEG C, preferably 75-85 DEG C, more preferably 80 DEG C.
The temperature of the refluxing extraction influences entire extraction process, comprehensively considers dissolution object, and avoid the molten of impurity
Equal many factors out;By cooperation said extracted temperature and extracting solution ingredient, can take into account specific in extraction dissolution roundpod jute leaf
Ingredient isoquercitin, Quercetin and Kaempferol, and avoid dissolving out other water-soluble substances, reduce activity.
Preferably, the time of the refluxing extraction is 1-3h, preferably 1.5-2.5h, more preferably 2h.
Preferably, after extraction, it is centrifuged off precipitating, collects liquid.It is furthermore preferred that the revolving speed of the centrifugation is 6000-
10000rpm/min, preferably 8000rpm/min;The time of the centrifugation is 5-15min, preferably 10min.
The present invention synchronizes by the way that specific testing conditions are arranged and detects isoquercitin in extract, Quercetin and kaempferia galamga
The content of phenol.Specifically, the phosphoric acid that mobile phase is the methanol that volume ratio is 55 ﹕ 45 and mass fraction is 0.5%;Flow velocity is
0.8mL/min, column temperature: 25 DEG C;Ultraviolet detection wavelength: 360nm;Sample volume: 20 μ L.
By external standard method, the isoquercitin of certain proportion and concentration, the hybrid standard liquid of Quercetin and Kaempferol are prepared, is adopted
It is measured with identical HPLC testing conditions, calculates the content of isoquercitin in extract, Quercetin and Kaempferol.
The present invention also provides what a kind of extracting method using flavonols component in the roundpod jute leaf was extracted to mention
Take object.
It include isoquercitin, Quercetin and Kaempferol in the extract.
Wherein, the concentration of the isoquercitin is 30-93 μ g/mL, and the concentration of the Quercetin is 1-5 μ g/mL, the mountain
How the concentration of phenol is 0.1-4 μ g/mL.
Said extracted object, for tyrosinase activity inhibiting rate up to 85.56%, to hydroxy radical, superoxide anion
The Scavenging activity of free radical and DPPH free radical can reach 97.61%, 62.66% and 88.15%, have excellent inhibition junket ammonia
