Embodiment 1

[0046] The determination of embodiment 1 optimum test condition

[0047] 1. Production equipment

[0048] (1) Extraction tank: There are two flower bars inside, which are used to extract the active ingredients in the raw materials;

[0049] (2) Solvent storage tank: used to store solvents;

[0050] (3) Circulation pump: used for solvent circulation;

[0051] (4) High level tank: used to store the leachate;

[0052] (5) Falling film evaporator: used to evaporate solvent and concentrate immersion liquid;

[0053] (6) Condenser: used for condensation of solvent;

[0054] (7) Receiving bottle: to receive the concentrate.

[0055] 2. Experimental content

[0056] 1. The influence of harvesting time on the yield of extract

[0057] (1) The purpose of the experiment: to determine the best harvesting time through the experiment, and obtain the highest extraction yield of the extract.

[0058] (2) Experimental method: Three growth stages were designed, and extracts were extract...

Embodiment 2

[0080] The extraction of embodiment 2 mosquito grass extract

[0081] Step 1. Raw material pretreatment

[0082] From June to July, when 70% of the flowers of Mosquito grass are open, the raw materials of Mosquito grass are harvested, and the lower withered leaves and thick stems are removed.

[0083] Step 2. Put the raw materials into the flower fence. It is required that the filling is uniform and weighed. The upper and lower flower fences are one can, and each can is filled with 300 kg.

[0084] Step 3: Put the fence into the extraction tank with an electric hoist.

[0085] Step 4: Inject petroleum ether with a boiling range of 60° C. into the storage tank, and add 900 liters of petroleum ether.

[0086] Step 5. First soak for 2.5 hours, then open the valve of the circulation system, start the circulation pump to circulate for 30 minutes, and then circulate once every hour for a total of six hours, and circulate three times.

[0087] Step 6: After the leaching is complet...

Abstract

The invention discloses a method for extracting mosquito grass extract, which relates to the field of mosquito grass processing and solves the problem of low extraction rate existing in the existing extraction methods of mosquito grass extract. The invention includes: pretreatment of mosquito grass raw materials, extraction, concentration, decompression concentration, recovery of solvent, and mosquito grass extract products. The present invention mainly adopts dynamic and static immersion and flower bed fixed solvent circulation leaching extraction process to prepare the extract of Mosquito, researches the extraction process of the extract of Mosquito, studies the harvesting time of Mosquito and the determination of the extract content in different parts , Extraction time, extraction methods and other aspects of the influence on the yield of the extract, the obtained product was evaluated and tested for aroma evaluation and application, which provided a scientific basis for guiding production. The invention has simple process and equipment, less investment, no waste of raw materials, low cost, good quality and high yield of the extract, which can reach 0.48%.

Description

technical field [0001] The invention relates to the technical field of mosquito grass processing, in particular to a method for extracting mosquito grass extract. Background technique [0002] Mosquito is a perennial herb of the genus Filipendula in the Rosaceae family. It mostly grows on hillsides, riverside wetlands, meadows and forest margins. 1 to 1.4 meters high. The rhizome is stout, runs horizontally, and has many fibrous roots. The diameter is erect, stout, finely ribbed, smooth, and brown. Leaves alternate, pinnately compound or interrupted pinnately compound; basal leaves and lower cauline leaves have long stalks; leaves are thick; apical leaflets are extra large, palmately 7-9 deeply lobed, 8-13 cm long. 12-15 cm wide, lobes broadly lanceolate or oblong-lanceolate, apex acuminate or long acuminate, leaf margins with irregular coarse serrations. Green above, densely white hairs below, with raised veins; a pair of lateral leaflets, often 3-lobed; stipules large,...
