Embodiment 1

[0019] Put 1000g of Caulis chinensis in the homogenizer, mix and homogenize with 60% ethanol solution of 1 times the weight of medicinal materials, and extract for 10min under the conditions of 185W and 8000r / min; add 3 times of 60% ethanol after homogenization , using dual-frequency ultrasonic for extraction, the ultrasonic frequency is 20KHz, 40KHz, the power is 400W, continuous extraction at 60°C for 90min, filtered, the filtrate is concentrated until no alcohol smell; the concentrated solution is extracted twice with petroleum ether, combined extracts, anhydrous Dry over sodium sulfate, and concentrate under reduced pressure to obtain 5.93 g of volatile oil of P. chinensis.

Embodiment 2

[0021] Put 1000g of Caulis chinensis in the homogenizer, mix and homogenize it with 65% ethanol solution which is 2 times the weight of the medicinal material, and extract it for 15min under the conditions of 185W and 10000r / min; add 4 times the 65% ethanol after homogenization , using dual-frequency ultrasonic for extraction, ultrasonic frequency is 20KHz, 40KHz, power is 600W, continuous extraction at 70°C for 120min, filtered, the filtrate is concentrated to no alcohol smell; the concentrated solution is extracted 3 times with ether, combined extracts, anhydrous sulfuric acid Sodium-dried, concentrated under reduced pressure to obtain 7.01 g of volatile oil of Gallus chinensis.

Embodiment 3

[0023] Put 1000g of Caulis chinensis in the homogenizer, mix and homogenize with 70% ethanol solution of 1 times the weight of the medicinal material, extract for 12min under the conditions of 185W and 9000r / min; add 3 times of 70% ethanol after homogenization , using dual-frequency ultrasonic for extraction, the ultrasonic frequency is 20KHz, 40KHz, the power is 500W, continuous extraction at 65°C for 100min, filtered, the filtrate is concentrated until no alcohol smell; the concentrated solution is extracted twice with petroleum ether, combined extracts, anhydrous Dry over sodium sulfate, and concentrate under reduced pressure to obtain 6.39 g of volatile oil of P. chinensis.

Abstract

The invention relates to a method for extracting Chinese fevervine herb volatile oil. The method is characterized by comprising the following steps: uniformly mixing and homogenizing rhizome of Chinese fevervine herb and a 60-70 percent ethanol solution of which the weight is 1-2 times that of medicinal materials in a homogenizer, and extracting for 10-15 minutes; adding 3-4 times of 60-70 percent ethanol after homogenizing, extracting by adopting dual-frequency ultrasonic waves at the ultrasonic power of 400-600W, continuously extracting at the temperature of 60-70 DEG C for 90-120 minutes, filtering, and concentrating the filtrate until alcohol taste is eliminated; and extracting the concentrated solution for 2-3 times by using an organic solvent, merging the extracting solutions, drying through anhydrous sodium sulfate, performing vacuum concentration, and obtaining the Chinese fevervine herb volatile oil. The method is simple in operation, short in extraction time and high in yield and is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for extracting the volatile oil of chrysanthemum cactus, belonging to the field of extraction and separation of effective components of natural plants. Background technique [0002] Chicken dung vine is a Rubiaceae plant, a perennial herbaceous vine, which has the functions of dispelling wind and dampness, relieving pain and detoxification, digestion and accumulation, promoting blood circulation and reducing swelling. Pain, dyspepsia, malnutrition in children, bronchitis, radiation-induced leukopenia; topical dermatitis, eczema, and sore swelling. [0003] The chemical constituents of the volatile oil of C. chinensis are esters, hydrocarbons, ketones, aldehydes, carboxylic acids and sulfur-containing organic compounds. Among these components, dimethyl disulfide has a peripheral nerve blocking effect, which may become one of the peripheral nerve mechanisms of the analgesic, anticonvulsant, and antitussive effects of ch...
