Abstract
The invention discloses a preparation method of a Chinese wampee leaf extract. The preparation method comprises the steps of cleaning the raw material, drying, extracting by taking a low carbon alcohol as an extracting agent, carrying out ultrasonic treatment, concentrating and drying to obtain the Chinese wampee leaf extract. The Chinese wampee leaves are taken as the raw material, the active ingredients of the Chinese wampee leaves are extracted by use of an ultrasonic assisted organic solvent method, alkaloids having a relatively high content in the Chinese wampee leaves are taken as an index, and the content of alkaloids in the prepared Chinese wampee leaf extract is high; the preparation method is simple and short in period, and makes a significant contribution to the development of food fresh keeping, natural preservatives and comprehensive utilization of the Chinese wampee leaves.
Description
Technical field
The present invention relates to extraction field, specifically, relate to a kind of preparation method of Folium clausenae lansii extract.
Background technology
At present, both at home and abroad all, low toxicity efficient at Devoting Major Efforts To Developing, wide spectrum and economical and practical antiseptic are found and are had the important channel that sterilization or biocidal property material become exploitation natural antiseptic agent from plant.Clausena lansium (Lour.) Skeels [Clause na
Lansium (Lour.) Skeels] belong to rutaceae, yellow weasel, originates in south China, mainly to be distributed in south China each province, especially with Guangdong, Guangxi, Fujian etc., economizing cultivated area larger, is one of famous " the good fruit in the south of the Five Ridges ", have the title of " treasured in fruit ".Its fruit is rich in sugar, organic acid, pectin, Vc, volatile oil, flavone etc., has higher nutritive value and important medical value.The leaf of Clausena lansium (Lour.) Skeels, bark, sarcocarp etc. also have application on Chinese medicine, and Folium clausenae lansii is bitter, pungent, property flat, has the heat radiation of inducing sweat, the pleasant function of reducing phlegm, be mainly used in influenza, cerebrospinal meningitis and malaria etc., visible it there is good medical value, but it is developed, current domestic research is few.
Summary of the invention
The object of this invention is to provide and a kind ofly take low-carbon alcohols as extractant, ultrasonic echography is prepared Folium clausenae lansii extract.
For achieving the above object, the present invention adopts following technical scheme:
A kind of preparation method of Folium clausenae lansii extract: comprise the following steps:
Step 1: Folium clausenae lansii is cleaned to oven drying at low temperature at 45-55 ℃;
Step 2: dry Folium clausenae lansii is pulverized, crossed 40-50 mesh sieve;
Step 3: take low-carbon alcohols as extractant, the Folium clausenae lansii after sieving is ultrasonic in ultrasound wave, twice of supersound extraction;
Step 4: by the extracting liquid filtering of twice, merging filtrate, vacuum concentration obtains the Folium clausenae lansii extract of paste;
Step 5: the Folium clausenae lansii extract of paste is dried, obtain pulverous Folium clausenae lansii extract.
Further, described low-carbon alcohols is methanol, ethanol, propanol, isopropyl alcohol or butanols.
Further, the solid-liquid ratio of Folium clausenae lansii and extractant is: 1:(10-15).
Further, described ultrasonic condition is: supersonic frequency 35-40Hz, ultrasonic power 250W-300W, ultrasonic time 20-30 minute.
Further, the condition that the Folium clausenae lansii of described paste is dried is: temperature 40-50 ℃, time 2-3 hour.
Further, the condition of described vacuum concentration is temperature 50-65 ℃, and vacuum is 0.05MPa-0.1 MPa, is concentrated into the 1/4-1/3 of original extracting liquid volume.
Further, the alkaloidal content in the Folium clausenae lansii extract of preparation is more than 55%.
Beneficial effect: the present invention be take Folium clausenae lansii as raw material, adopts ultrasonic auxiliary organic solvent method to extract Folium clausenae lansii active component, and the more alkaloid of content in Folium clausenae lansii of take is index, and the alkaloidal content in the Folium clausenae lansii extract of preparing is high; Preparation method of the present invention is simple, the cycle is short, for huge contribution is made in the exploitation of food fresh keeping, natural antiseptic agent and the comprehensive utilization of Folium clausenae lansii.
The specific embodiment
Below in conjunction with embodiment, the present invention is further detailed explanation.
