Embodiment 1

[0013] Embodiment 1: chop 10Kg of maple gum raw material into pieces of 6cm × 4cm × 1cm with a knife, pour the block body balsam raw materials into a dissolving tank, add concentration until immersion in 95% ethanol, and stir in an extractor Dissolve; then filter and precipitate the maple gum ethanol solution, put the filtrate into a vacuum concentration tank for concentration, heat in a water bath, keep the temperature in the concentration tank between 45 and 50°C, condense, and collect distillate ethanol in a vacuum. When the recovery of ethanol is almost finished, stop heating and cooling. Turn on the switch, put the concentrated liquid into the container, and obtain the required rue extract. The product is brownish-yellow to tan paste, with sweetgum resin aroma, relative density (20°C) of 0.960-1.060, insolubles in alcohol ≤ 2.0%, loss on drying ≤ 27.0%. Wherein the relative density can be measured by the method specified in Chinese Pharmacopoeia (version one in 2000) app...

Embodiment 2

[0016] Use a knife to chop 10Kg of the maple resin raw material into blocks of 3cm×3cm×2cm, pour the block body balsam raw materials into a dissolving tank, add a concentration of 82% ethanol to immerse, and dissolve; then filter the maple resin ethanol solution, The filtrate is concentrated in a vacuum concentration tank, heated in a water bath, and the temperature in the concentration tank is kept at 55-60°C, condensed, and the distillate ethanol is collected in a vacuum. When ethanol is recovered to a certain amount, stop heating and cool down. Turn on the switch, put the concentrated liquid into the container, and then dry the concentrated liquid product (rue extract) through drying (air drying) to obtain a brownish-yellow to tan solid, which is the dry product of pure maple gum. This product has sweetgum resin Aroma, insolubles in alcohol ≤ 2.0%, loss on drying ≤ 5.0%.

Embodiment 3

[0018] Use a knife to chop 10Kg of maple gum raw material into blocks of 5cm×4.5cm×1.5cm, pour the blocky balsam raw materials into a dissolving tank, add ethanol with a concentration of 90% to immerse, stir and dissolve in a closed extractor; Then filter and precipitate the maple gum ethanol solution, put the filtrate into a vacuum concentration tank to concentrate, heat in a water bath, keep the temperature in the concentration tank at 40-45°C, condense, and collect distillate ethanol in a vacuum. When ethanol is recovered to a certain amount, stop heating and cool down. Turn on the switch and put the concentrated liquid into the container. The concentrated liquid product is brownish-yellow to tan paste, with the aroma of liquidambar resin. The relative density (20°C) is 0.960-1.060, and the insoluble matter in alcohol is ≤2.0%. Loss on drying ≤ 27%.

Abstract

A process for preparing the rue extract from liquidambar resin through cutting off, dissolving in alcohol, filtering, depositing, concentrating the filtrate, heating in water bath, condensing, and recovering alcohol. Its advantages are high purity and low cost.

Description

(1) Technical field [0001] The invention relates to a method for making maple gum into rue extract. (2) Background technology [0002] Liquidambar Formesana Llance is a resin secreted from Liquidambar Formesana Llance, a plant of the family Hamamelis, and belongs to the natural fragrance of plants. Liquidambar is also a well-known traditional Chinese medicine. It was first recorded in "Xinxiu Materia Medica" (AD 659) in the Tang Dynasty. , traumatic bleeding, etc. The existing production process has not formed an effective method, resulting in low purity and many impurities in the obtained product, which affects the application of this product. So far, there is no corresponding national standard or industry standard. (3) Contents of the invention [0003] The object of the present invention is to provide a kind of method that sweetgum resin is prepared into a kind of extract-rue extract (has another name called sweetgum extract), and the prepared rue extract can be mainl...
