Problems solved by technology

The steam distillation method has a high temperature and takes a long time, which is easy to change the unstable and easily oxidized components to humidity and heat; while the supercritical CO 2 Although the extraction method has the advantages of high yield, high product concentration and no solvent residue, its equipment is expensive and maintenance is difficult, so it is not suitable for industrial production

Embodiment 1

[0013] Dry the fresh leaves of Eagle's Claw flower in the shade, crush them, pass through a 40-mesh sieve, take 1000g, add 50% ethanol solution 3 times the weight of the raw material, and place it in an ultrasonic-microwave extractor for extraction. Control the ultrasonic wave to 600W and the microwave power to 500W Continuously extract for 1 hour, filter, and extract the filtrate twice with petroleum ether, combine the extracts, dry over anhydrous sodium sulfate, and concentrate under reduced pressure to obtain 14.5 mL of light yellow volatile oil of Eagle Claw Flower.

Embodiment 2

[0015] Dry the fresh leaves of Eagle's Claw flower in the shade, crush them, pass through a 40-mesh sieve, take 1000g, add 60% ethanol solution 5 times the weight of the raw material, and place it in an ultrasonic-microwave extractor for extraction. Control the ultrasonic wave to 600W and the microwave power to 600W Extract continuously for 2 hours, filter, and extract the filtrate twice with ether, combine the extracts, dry over anhydrous sodium sulfate, and concentrate under reduced pressure to obtain 16.3 mL of light yellow volatile oil of Eagle Claw Flower.

Embodiment 3

[0017] Dry the fresh leaves of Eagle's Claw flower in the shade, crush them, pass through a 40-mesh sieve, take 1000g, add 55% ethanol solution 4 times the weight of the raw material, and place it in an ultrasonic-microwave extractor for extraction. Control the ultrasonic wave to 600W and the microwave power to 800W Continuously extract for 3 hours, filter, and extract the filtrate with petroleum ether three times, combine the extracts, dry over anhydrous sodium sulfate, and concentrate under reduced pressure to obtain 15.1 mL of yellow volatile oil of Eagle Claw Flower.

Abstract

The invention relates to an extraction method of artabotrys hexapetalus volatile oil, and more specifically relates to an ultrasonic-microwave method used for extracting artabotrys hexapetalus volatile oil. The extraction method comprises following steps: artabotrys hexapetalus fresh leaves are dried in the shade, smashed, and sieved using a sieve of 40 meshes; an ethanol solution with a concentration of 50 to 60% is added, wherein the weight amount of the ethanol solution accounts for 3 to 5 times of that of the raw material; an obtained mixture is delivered into an ultrasonic-microwave extractor for extraction; filtering is carried out, an obtained filtrate is subjected to organic solvent extraction for 2 to 3 times, and extraction liquid obtained via the 2 to 3 times of extraction is collected and mixed; anhydrous sodium sulfate is used for drying; and vacuum concentration is carried out so as to obtain artabotrys hexapetalus volatile oil. Operation of the extraction method is simple; solvent using amount is less; reaction conditions are mild; and destroy of the volatile oil component structure is minimized.

Description

technical field [0001] The invention relates to a method for extracting volatile oil from hawk's claw flower, and belongs to the technical field of extracting effective components of natural products. Background technique [0002] Accordia stenosa is a plant of the genus Accordiaceae of tomato litchi. There are more than 100 species of this genus in the world, and they are mainly distributed in tropical and subtropical regions. In the folk, the stenotic eagle claw flower has been used as a medicinal plant for a long time. It has the functions of clearing away heat and detoxification, reducing inflammation and relieving pain, and can also be used to treat lymphatic tuberculosis of the head and neck. There are many reports on the plants of the genus Eagle's claw at home and abroad, but the research on the extraction method of the volatile oil of the genus Eagle's claw has not been reported so far. Volatile oil is one of the active ingredients of plants. Studies have shown tha...
