(1) Leaching tank: two flower columns are arranged in the device and are used for extracting effective ingredients in the raw materials;
(2) a solvent storage tank: for storing the solvent;
(3) circulating pump: for solvent circulation;
(4) a head tank: for storing the leach liquor;
(5) a falling film evaporator: evaporating the solvent and concentrating the extract;
(6) a condenser: for condensation of the solvent;
(7) receiving a bottle: a concentrate is received.
Second, the experimental contents

(1) Purpose of the experiment: the best recovery time is determined through experiments, and the highest extract extraction yield is obtained.
(2) The experimental method comprises the following steps: three growth stages are designed, and extract extraction is respectively carried out.
(3) The experimental contents are as follows: the growth stages are divided as follows: early flowering, flowering and fruit stage.
(4) The results are shown in Table 1.
TABLE 1 Effect of harvest time on extract yield
As can be seen from the table above, the yield of the extract extracted in the flowering phase is highest in the harvesting time, and the yield in the fruit phase is only second, so that the fluid can be harvested in both the flowering phase and the fruit phase. According to experimental data, the harvest season of the Filipendula esculenta is preferably arranged from 7 to august.
2. Determination of extract content of different parts
(1) Purpose of the experiment: the content of the extractum at different parts is determined by tests.
(2) The experimental method comprises the following steps: four growth stages are designed, and the extractum is extracted respectively.
(3) The experimental contents are as follows: selecting the leaves, flowers, stems and whole plants of the Filipendula ulmaria to extract the extractum respectively.
(4) The results are shown in Table 2.
TABLE 2 determination of extract content at different sites
Leaf of Chinese character | Stem of a tree | Flower (A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A. B. A | Whole plant | |
Weight (kg) | 30 | 25 | 40 | 60 |
De oil (g) | 180 | 20 | 320 | 246 |
Yield (%) | 0.6 | 0.08 | 0.8 | 0.41 |
As can be seen from the comparison of the data in Table 2, the extract content is highest in flower, lowest in leaf and lowest in stem. Therefore, during extraction, part of thick stems can be removed, so that the content of the extract is improved, and the economic benefit is improved.
3. Influence of extraction time and extraction mode on extract
Fresh Filipendula ulmaria raw material is put into three leaching tanks respectively, each 100kg, and petroleum ether is added to make the raw material submerged (the dosage is about 500L).
The test scheme is as follows: tank I: the solution is statically immersed for 24 hours. Tank II: and (5) carrying out dynamic immersion for 3 hours. Tank No. iii: the immersion was carried out for 2 hours and then cycled every 1 hour for 30 minutes for a total of six hours (three cycles for 1.5 hours). And (4) after the completion, cleaning the leaching liquor, washing the residual residues with new petroleum ether twice respectively, and pumping the washing liquor into respective leaching liquor for concentration and refining to obtain extract. The test was repeated twice, and the results are shown in Table 3.
TABLE 3 comparative table of leaching mode
From the data in table 3, it can be seen that: the static leaching yield is higher, but the leaching time is too long, which is not beneficial to the industrialized production. The dynamic leaching time is shorter, but the yield is low and uneconomical. The dynamic and static combination has obvious advantages in yield and time, is economical and time-saving, and therefore, the dynamic and static combination in the production is better. That is, the immersion is performed for 2 hours, and then the immersion is performed every 1 hour for 30 minutes for a total of six hours (the total time of the three times of immersion is 1.5 hours).
