Abstract
The invention relates to the field of processing of subsidiary agricultural products, and particularly discloses a peony polyphenol extraction process. The peony polyphenol extraction process adopts peony petals as a raw material and is characterized in that the peony petals are put into a narrow-mouth flask, an ethanol solution of which the volume fraction is 10-70 percent is added according to a material/liquid ratio of (1:50)-(1:600), the narrow-mouth flask is put into a water bath kettle, and then an ultrasonic probe is arranged in the middle of the solution to carry out ultrasonic extraction. The peony polyphenol extraction process disclosed by the invention is short in extraction time and high in efficiency, and the peony petals which are generally agricultural wastes are taken as the raw material for extracting an active substance, thus the production value of the peony is increased, wastes are changed into valuable substances, and resource utilization of agricultural production wastes is realized.
Description
(1) technical field
The present invention relates to agricultural byproducts processing field, particularly a kind of extraction process of Flos Moutan polyphenol.
(2) background technology
Flos Moutan is the traditional medicine of heat-clearing and toxic substances removing, and its bitter in the mouth, property are flat, has and effect of blood, hemopoietic, removing heat from blood, cures mainly the blood fire second of the three ten-day periods of the hot season, heat clearing away and restlessness relieving.Modern analysis shows, the polyphenols in Flos Moutan is the material base of its Mars.At present, Flos Moutan is except the ornamental flower as important, mainly utilize its root bark (being Cortex Moutan) as Chinese crude drug, owing to being subject to the restriction of florescence and weather conditions, economy and trade while causing that the flowers are in blossom, tourist activity prosperity, the bad situation of keeping going by painstaking effort when flower falls, and be limited by deeply add backward in technique, there is every year a large amount of Flos Moutaies to slattern in vain, directly lose as garbage.In recent years, in order to change this phenomenon, many experts and scholars successively composition and the application to Flos Moutan have launched omnibearing research, to Flos Moutan being carried out to the exploitation of the degree of depth, changed into the available important resource of a kind of mankind, to promote the added value of Paeonia suffruticosa industry.
Mainly anthocyanin type, antioxidant activity and the volatile oil component etc. of Flos Moutan are studied at present, in addition, only have take methanol as solvent, the Flos Moutan extract polyphenol that adopts ultrasonic method to extract, the method methanol used has certain toxicity, and yield lower (content is 0.146%), and adopt conventional water-bath extracting method, has long, the shortcoming (0.192%) such as extraction ratio is low of extraction time.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, and the extraction process of a kind of handling safety, short, Flos Moutan polyphenol that yield is high consuming time is provided.
The present invention is achieved through the following technical solutions:
A kind of extraction process of Flos Moutan polyphenol, take peony petal as raw material, it is characterized in that: peony petal is placed in to narrow-mouthed flash, and adding volume fraction according to solid-liquid ratio 1:50-1:600 is the alcoholic solution of 10-70%, and narrow-mouthed flash is placed in to water-bath, then ultrasonic probe is placed in to liquid centre position, carry out ultrasonic extraction, extraction time is 10-40min, and temperature is 30 ℃, power is 1000w, finally obtains product.
The present invention adopts ethanol extraction polyphenol, accurate adjustment solid-liquid ratio, and this common water-bath is extracted as ultrasonic extraction, and improved efficiency is more than 1 times.
More excellent scheme of the present invention is:
The solid-liquid ratio of described peony petal and alcoholic solution is 1:500, and the volume fraction of alcoholic solution is 50%, and extraction time is 20min.
Extraction time of the present invention is short, efficiency is high, and selecting is generally that raw material extracts active substance as the peony petal of agricultural wastes, has promoted the output value of peony petal, turns waste into wealth, and has realized the recycling of agricultural production garbage.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 is the affect figure of solid-liquid ratio of the present invention on polyphenol extraction ratio;
Fig. 2 is the affect figure of extraction time on polyphenol extraction ratio;
Fig. 3 is the affect figure of volume fraction of ethanol on polyphenol extraction ratio.
(5) specific embodiment
Embodiment:
The present invention utilizes impulse ultrasound technology to extract the aldehydes matter in peony petal, its processing step is: take 1.0g peony petal powder and be placed in narrow-mouthed flash, add the alcoholic solution (volume fraction of ethanol is 10 ~ 70%) of variable concentrations according to solid-liquid ratio 1:50 ~ 1:600, a thin mouthful beaker is placed in to water-bath, then ultrasonic probe is placed in to liquid centre position, extraction time is 10 ~ 40min, carries out ultrasonic extraction, extracting temperature is 30 ℃, and power is 1000w.
It is single factor that the present invention chooses solid-liquid ratio, extraction time, volume fraction of ethanol, and they see Fig. 1, Fig. 2 and Fig. 3 to the extraction ratio of polyphenol.
As a kind of preferred version, technological parameter of the present invention is: solid-liquid ratio is 1:500, and volume fraction of ethanol is 50%, and extraction time is 20min, and extracting temperature is 30 ℃, and power is 1000w.With this understanding, the extraction ratio of peony petal polyphenol can reach 0.393%.
Claims (2)
1. the extraction process of a Flos Moutan polyphenol, take peony petal as raw material, it is characterized in that: peony petal is placed in to narrow-mouthed flash, and adding volume fraction according to solid-liquid ratio 1:50-1:600 is the alcoholic solution of 10-70%, and narrow-mouthed flash is placed in to water-bath, then ultrasonic probe is placed in to liquid centre position, carry out ultrasonic extraction, extraction time is 10-40min, and temperature is 30 ℃, power is 1000w, finally obtains product.
2. the extraction process of Flos Moutan polyphenol according to claim 1, is characterized in that: the solid-liquid ratio of described peony petal and alcoholic solution is 1:500, and the volume fraction of alcoholic solution is 50%, and extraction time is 20min.
