Abstract
The invention discloses an extraction method of dogwood volatile oil, which comprises the following steps: drying and crushing the cornus officinalis, and sieving the crushed cornus officinalis with a 40-mesh sieve; adding 60-70% ethanol solution 5-6 times of the weight of the raw materials, extracting by adopting ultrasonic wave with the frequency of 60KHz, filtering, and concentrating the filtrate until no alcohol smell exists; and (3) loading the obtained concentrated solution to a column through macroporous adsorption resin, eluting with chloroform with the volume of 4-6 times of that of the column and being 60-70%, collecting eluent, concentrating and drying. The extraction method of the invention is simple and easy to implement, has high yield, does not need a large amount of organic solvents, is safe and nontoxic, and is suitable for industrial production.
Description
The technical field is as follows:
the invention relates to the technical field of traditional Chinese medicines, and in particular relates to a method for extracting dogwood volatile oil.
Background art:
dogwood pulp contains 16 kinds of amino acids and, in addition, contains a large amount of elements essential to the human body. In addition, the composition contains physiologically active sapogenin sugar, polysaccharide, malic acid, tartaric acid, phenols, resin, tannin, vitamin A, C, etc. It has sour and astringent taste, and has effects of nourishing, invigorating stomach, promoting urination, nourishing liver and kidney, and invigorating qi and blood. It can be used for treating hypertension, soreness of waist and knees, vertigo, tinnitus, sexual impotence, spermatorrhea, and menorrhagia.
Ripening and drying fruits of the dogwood, and removing kernels to obtain the rare medicinal material namely the sweet potato meat. The fruit drugs are used as astringent hematinic and tonic; it has effects in invigorating stomach, nourishing liver and kidney, and treating anemia, lumbago, neurasthenia, and heart failure. It is sour and astringent in nature and flavor, entering liver and kidney meridians. Astringing and astringing, has effects of nourishing liver and kidney, and invigorating kidney and arresting seminal emission, and is suitable for treating soreness of waist and knees, spermatorrhea, giddiness and tinnitus caused by liver and kidney deficiency.
Cornel meat contains rich nutrient substances and functional components, and the cornel is listed as a medicine for enriching blood and securing essence, tonifying liver and kidney, regulating qi, tonifying deficiency, improving eyesight and strengthening body, which is collected from the compendium of materia Medica of the entire generations of medical generations in the Ming Dynasty Li Shizhen.
Cornus officinalis is mature fruit of Cornaceae plant with seed removed, and has effects of invigorating liver and kidney, and arresting seminal emission.
The existing method for extracting volatile oil from cornus officinalis comprises a steam distillation method, a solvent extraction method and the like, and has a plurality of defects: the effective components of the steam distillation method are easy to damage and volatilize, and the time is consumed; the solvent extraction method is not suitable for industrial production, although the biological activity is not easily destroyed.
The invention content is as follows:
the invention aims to provide the extraction method of the dogwood volatile oil, which has the advantages of safety, no toxicity, short time consumption, high extraction rate, simple process and continuous operation.
The invention comprises the following steps:
a. drying and crushing the cornus officinalis, and sieving the crushed cornus officinalis with a 40-mesh sieve;
b. adding 60-70% ethanol solution 5-6 times of the weight of the raw materials, extracting by adopting ultrasonic wave with the frequency of 60KHz, filtering, and concentrating the filtrate until no alcohol smell exists;
c. and (3) loading the obtained concentrated solution to a column through macroporous adsorption resin, eluting with chloroform with the volume of 4-6 times of that of the column and being 60-70%, collecting eluent, concentrating and drying.
The types of the macroporous absorption resin in the step c are XDA-1, HPD-400 and AB-8.
The extraction method of the invention is simple and easy, does not need a large amount of organic solvent, is safe and nontoxic, and is suitable for industrial production.
The specific implementation mode is as follows:
the invention is illustrated below by way of example, without the protection of the invention being restricted thereto.
Example 1:
drying and crushing the cornus officinalis, and sieving the crushed cornus officinalis with a 40-mesh sieve; adding 60% ethanol solution 5 times the weight of the raw materials, extracting with 60KHz ultrasonic wave, filtering, and concentrating the filtrate until no alcohol smell is present; loading the obtained concentrated solution on macroporous adsorbent resin XDA-1, eluting with 4 times of 60% chloroform, collecting eluate, concentrating, and drying.
Example 2:
drying and crushing the cornus officinalis, and sieving the crushed cornus officinalis with a 40-mesh sieve; adding 70% ethanol solution 6 times the weight of the raw materials, extracting with 60KHz ultrasonic wave, filtering, and concentrating the filtrate until no alcohol smell is present; loading the obtained concentrated solution on macroporous adsorbent resin HPD-400, eluting with 70% chloroform 6 times the column volume, collecting eluate, concentrating, and drying.
Example 3:
drying and crushing the cornus officinalis, and sieving the crushed cornus officinalis with a 40-mesh sieve; adding 60% ethanol solution 5 times the weight of the raw materials, extracting with 60KHz ultrasonic wave, filtering, and concentrating the filtrate until no alcohol smell is present; loading the obtained concentrated solution on macroporous adsorbent resin AB-8, eluting with 5 times of 60% chloroform, collecting eluate, concentrating, and drying.
