Embodiment 1
[0013] Grind the dried fruit of Yizhi, take 500g, put it in a glass container, add 3 times the weight of distilled water, use ultrasonic-microwave to extract, control ultrasonic 600W (normally on), and microwave power 500W to extract continuously for 4h, filter, and use the filtrate Extracted three times with ether, combined the extracts, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain an orange-yellow volatile oil with a strong fragrance, with a yield of 2.0%.
Embodiment 2
[0015] Grind the dried fruit of Yizhi, take 500g, put it in a glass container, add 5 times the weight of distilled water, use ultrasonic-microwave to extract, control ultrasonic 600W (normally on), and microwave power 800W to extract continuously for 3h, filter, and use the filtrate Extracted three times with n-hexane, combined the extracts, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain an orange-yellow volatile oil with a strong fragrance, with a yield of 2.3%.
Embodiment 3
[0017] Grind the dried fruit of Yizhi, take 500g, put it in a glass container, add 8 times the weight of distilled water, use ultrasonic-microwave to extract, control ultrasonic 600W (normally on), and microwave power 1000W to extract continuously for 2h, filter, and use the filtrate Cyclohexane extracted twice, combined the extracts, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to obtain an orange-yellow volatile oil with a strong fragrance, with a yield of 2.5%.

Abstract
The invention relates to a method for extracting alpinia oxyphylla volatile oil, in particular relates to a method for extracting alpinia oxyphylla volatile oil by adopting ultrasonic and microwave, and belongs to the technical field of natural plant extraction products. The method comprises the treatment steps of pulverizing dry alpinia oxyphylla fruits, putting into a glass vessel, adding distilled water in an amount which is 3-8 times weight of the alpinia oxyphylla, continuously extracting for 1-4 hours with ultrasonic and microwave by controlling the ultrasonic at 600W (normally open) and controlling the microwave power at 500-1,000W, filtering, extracting the filtrate with an organic solvent for 1-3 times, combining the extracts, drying with anhydrous sodium sulfate, and concentrating under reduced pressure, thus obtaining the alpinia oxyphylla volatile oil. The alpinia oxyphylla volatile oil is extracted through ultrasonic and microwave synergy by adopting a modern extraction technology, so that the method is simple, short in extraction time and high in selectivity, the yield of the volatile oil is significantly higher than that of the traditional extraction method, and the method is suitable for industrialized production.
Description
Technical field [0001] The invention involves a method of extracting oil from puzzle volatile oil, which specifically involves a method of using ultrasonic-microwave collaborative extraction puzzle volatile oil, which belongs to the field of natural plant extraction products. Background technique [0002] Puzzle, the dry fruits of the puzzle of the ginger family, aliases, puzzles and puzzles, are one of the four major southern medicines in Hainan.The theory of traditional Chinese medicine believes that it has the effect of "warm the spleen, warming the kidneys, solidifying qi, and astringent essence".Modern pharmacological research shows that puzzle has anti -cancer, strong heart, antibacterial, anti -inflammatory, and analgesic effects.Puzzle contains a variety of chemical ingredients, and its main component is volatile oil. The main components in the oil are eucalyptus oil, gingernne, gingerol, etc. [0003] The water vapor distillation method is the most commonly used method f...
