Problems solved by technology

[0008] In order to solve the current ginkgo essential oil only use supercritical CO 2 Fluid extraction cannot simultaneously enrich unsaturated fatty acids, ginkgo terpenoid lactones, flavonoids, lutein, β- and α-carotene carotenoids, the purpose of the present invention is to provide a method for extracting ginkgo essential oil, In the ginkgo essential oil obtained by this method, the unsaturated fatty acid accounts for more than 92% of the total fatty acid, the total flavonoid is more than 0.10%, contains bilobalide and ginkgolide A, B, C, and the total terpene lactone is more than 0.02%. Carotene, β- and α-carotene, the total amount of carotenoids > 1㎎ / 100g

Embodiment 1

[0108] Take 4 tons of ginkgo fruit, wash and drain. Put it into the crusher at a suitable speed, adjust the crusher 2900 / min, control the crushing particle size at 10 mesh, mix the crushed ginkgo nuts with purified water at a ratio of 1:15, and put it into an ultrasonic oscillator for vibration , oscillating at a frequency of 70-80HZ for 30 minutes, put the crushed ginkgo nuts that have been ultrasonically oscillated into a 5-stage cyclone separator at 0.1Mpa, and adjust the pressure to 0.3Mpa to separate the germ. The heavy ginkgo nuts are collected at the discharge port at the lower end of the cyclone, drained of purified water, and vacuum-dried until the water content is less than 5%. Put the dried ginkgo nuts into a pulverizer for crushing, and then sieve in a 200-mesh sieve. Put the sifted ginkgo nut powder into an airflow mill for wall-breaking crushing, and the crushing particle size is 1250 mesh. , add an appropriate amount of binder and mix evenly, put it into a gran...

Embodiment 2

[0110] Take 2 tons of ginkgo fruit, wash and drain. Put it into the crusher at a suitable speed, adjust the crusher 3200 / min, control the crushing particle size at 10 mesh, mix the crushed ginkgo nuts with purified water at a ratio of 1 to 9, and put it into an ultrasonic oscillator for vibration , oscillating at a frequency of 60HZ for 30 minutes, putting the crushed ginkgo nuts oscillated by ultrasonic at 0.1Mpa into a 4-stage cyclone separator, and adjusting the pressure to 0.8Mpa to separate the germ. The heavy ginkgo nuts are collected at the discharge port at the lower end of the cyclone, drained of purified water, and vacuum-dried until the water content is less than 5%. Put the dried ginkgo nuts into a pulverizer for crushing, and then sieve in a 200-mesh sieve, put the sifted ginkgo nut powder into a jet mill for wall-breaking crushing, and the crushing particle size is 2000 mesh , add an appropriate amount of binder and mix evenly, put it into a granulator for granu...

Embodiment 3

[0112] Take 5 tons of ginkgo fruit, wash and drain. Put it into the crusher at a suitable speed, adjust the crusher 3500 / min, control the crushing particle size at 30-40 mesh, mix the broken ginkgo nuts with purified water at a ratio of 1 to 6, and put it into the ultrasonic oscillator Vibrate at a frequency of 45-50HZ for 20 minutes, put the crushed ginkgo nuts that have been ultrasonically oscillated into a 6-stage cyclone separator at 0.1Mpa, and adjust the pressure to 1.0Mpa to separate the germ. The heavy ginkgo nuts are collected at the discharge port at the lower end of the cyclone, drained of purified water, and vacuum-dried until the water content is less than 5%. Put the dried ginkgo nuts into the pulverizer for crushing, and then sieve them in a 200-mesh sieve, put the sifted ginkgo nut powder into the jet mill for wall-breaking crushing, and the crushing particle size is 3000 mesh , add an appropriate amount of binder and mix evenly, put it into a granulator for g...

Abstract

The invention discloses a method for extracting ginkgo semen essential oil. On the basis of removing a germ by using an ultrasonic concussion-multistage cyclone separation technique, the ginkgo semenessential oil is obtained by adopting a supercritical CO2 extraction and molecular distillation integrated technology; the purposes of separating an impurity and enriching a functional substance are realized; a toxic component is decreased to an extremely low level, and the safe eating is ensured. The ginkgo semen essential oil extracted by using the extraction method provided by the invention hasunsaturated fatty acid accounting for more than 92% of total fatty acid and total flavone which is more than 0.10%, contains bilobalide, ginkgolide A, B and C, total terpene lactone which is more than 0.02%, xanthophyll, beta-carotene and alpha-carotene and carotenoid with a total amount more than 1 mg/100g. The functional substance has multiple biological functions of delaying senescence, lowering content of total cholesterol in blood, resisting oxidization, resisting a cancer, and the like, and has extremely good intervention effects on cardiovascular and cerebrovascular diseases and alleviating a neurodegenerative disease.

Description

technical field [0001] The invention relates to the technical field of plant essential oil extraction, in particular to a method for extracting ginkgo essential oil. Background technique [0002] Ginkgo fruit, commonly known as Ginkgo Semen, is the dry mature seed of Ginkgo biloba L. and is one of the famous nuts. [0003] Deng Qianchun, Zeng Changmin, Tian Binqiang, etc. in "Extraction of Ginkgo Oil and Analysis of Fatty Acid Composition" (Deng Qianchun, Zeng Changmin, Tian Binqiang, etc., Extraction of Ginkgo Oil and Analysis of Fatty Acid Composition, China Oils, 2007,32(10):76-79) The invention discloses that fresh ginkgo fruit is shelled, freeze-dried, pulverized, and extracted by supercritical fluid to obtain ginkgo oil. The obtained ginkgo oil contains 16 kinds of fatty acids, of which unsaturated fatty acids account for 91.4% of the total fatty acid content, while linoleic acid and oleic acid account for 75.4%.
