Embodiment 1

[0015] Example 1: Preparation of Rabbit Ear Grass Extract

[0016] (a) Mix 5 kg of dried rabies ear grass and bindweed (accounting for 10% of the total weight), grind them, and extract them under reflux with 70% ethanol solution (20 L x 3 times), combine the extracts, concentrate until there is no alcohol smell to obtain ethanol Extract the concentrated solution; (b) dilute the ethanol extracted concentrated solution obtained in step (a) with water (3L), and successively use petroleum ether (3L×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol Extract (3L×3 times), concentrate under reduced pressure to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (c) n-butanol extract is dissolved in water, filtered, and filtered with AB-8 To enrich the active ingredient in the resin, first wash 8 column volumes with 8% ethanol to remove large polar components, then elute 15 column volumes with 75% ethanol, collect the 75% ethanol e...

[0017] Example 2: Preparation of Rabbit Ear Grass Extract

[0018] (a) Mix 5kg of dried Rabbit's Ear Grass and Convolvulus convolvulus (accounting for 5% of the total weight), pulverize, extract with 65% ethanol solution under heat reflux (20L x 3 times), combine the extracts, concentrate until there is no alcohol smell to obtain ethanol Extract the concentrated solution; (b) dilute the ethanol extracted concentrated solution obtained in step (a) with water (3L), and successively use petroleum ether (3L×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol Extract (3L×3 times), concentrate under reduced pressure to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (c) n-butanol extract is dissolved in water, filtered, and filtered with AB-8 To enrich the active ingredient in the resin, wash 9 column volumes with 6% ethanol to remove large polar components, then elute 17 column volumes with 70% ethanol, collect the 70% ethano...

Embodiment 3

[0019] Example 3: Preparation of Rabbit Ear Grass Extract

[0020] (a) Mix 5kg of dried rabies ear grass and bindweed (accounting for 15% of the total weight), pulverize, extract with 75% ethanol solution under heat reflux, combine the extracts (20L×3 times), concentrate until there is no alcohol smell to obtain ethanol Extract the concentrated solution; (b) dilute the ethanol extracted concentrated solution obtained in step (a) with water (3L), and successively use petroleum ether (3L×3 times), ethyl acetate (3L×3 times) and water-saturated n-butanol (3L×3 times) extraction, concentration under reduced pressure to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; To enrich the active ingredients in the resin, wash 7 column volumes with 10% ethanol to remove large polar components, then elute 13 column volumes with 80% ethanol, collect the 80% ethanol eluate, and concentrate under reduced pressure.

Abstract

The invention discloses a traditional Chinese medicine common pecteilis root extract capable of improving production performance of cattle. The common pecteilis root extract is prepared by the following method: (a) mixing dried common pecteilis roots with field bindweeds, performing crushing, performing hot reflux extraction with an ethanol solution of 65-75%, merging extracting solutions, and performing concentration until alcohol taste does not exist so as to obtain an alcohol extract concentrated solution; (b) diluting the alcohol extract concentrated solution obtained in the step (a) with water, performing extraction by sequentially using petroleum ether, ethyl acetate and water-saturated n-butanol, and performing decompression concentration so as to obtain a petroleum ether extract, an ethyl acetate extract and an n-butanol extract; (c) dissolving the n-butanol extract with water, performing filtration, enriching active components with AB-8 type macroporous resins, flushing 7-9 column volumes with ethanol of 6-10% so as to remove large polarity components, eluting 13-17 column volumes with ethanol of 70-80%, collecting an ethanol eluent of 70-80%, and performing decompression concentration, wherein the convolvulus arvensis accounts for 5-15% of the total weight of the common pecteilis roots and the convolvulus arvensis.

Description

technical field [0001] The invention belongs to animal husbandry and relates to veterinary medicines, in particular to a traditional Chinese medicine Largoscarina extract for improving the production performance of cattle. The extract can significantly improve the production performance of cattle. Background technique [0002] Rabbit Ear Grass is the root tuber of orchidaceae. The roots are collected in autumn, washed and dried in the sun or used fresh. The original plant dragon head orchid is an annual herb with a height of 45-120 cm. There are 2 tuberous roots, narrowly spindle-shaped. Leaves alternate, covering directly to the bottom of the flower; leaves lanceolate, 7-10 cm long, 1.5-3 cm wide, apex long and acuminate, base broadly cuneate, sheath-shaped, clasping stems, parallel veins near ribs, slightly covered on both sides ancestral hair. Racemes with 3-5 flowers; bracts leaf-like; flowers large, white; sepals broadly ovate, spreading, blunt, slightly oblique on ...
