Embodiment 1

[0030] Ginkgo biloba extraction process:

[0031] (1) Take dried ginkgo leaves and grind them into 450 mesh fine powder; (2) Take 10 kg of ginkgo leaf fine powder and add 200 kg of ethanol with a concentration of 35%, stir and mix evenly, after soaking for 6 hours, heat at 65°C, set the speed at 45rpm , stirred and extracted twice, respectively, the first extraction was 3.5h, the second extraction was 2.5h, the combined extracts were filtered with 350 mesh industrial filter cloth, and the filtrate was centrifuged at 8000r / min for 15min to obtain the supernatant; (3) Take the supernatant and filter it with a 0.22 μm microporous membrane to obtain the fine filtrate; (4) Take the fine filtrate to recover ethanol under reduced pressure, concentrate to 10 g raw and dried ginkgo leaves / ml concentrated juice, and set aside.

Embodiment 2

[0033] (1) Take dried ginkgo leaves and crush them into 550 mesh fine powder; (2) Take 10 kg of ginkgo leaf fine powder and add 300 kg of ethanol with a concentration of 45%, stir and mix evenly, after soaking for 5 hours, heat at 55°C, set the speed at 35rpm, stirred and extracted twice, respectively, the first extraction was 3.5h, the second extraction was 2.5h, the combined extracts were filtered with 350 mesh industrial filter cloth, and the filtrate was centrifuged at 10000r / min for 15min to obtain the supernatant; (3 ) Take the supernatant and filter it with a 0.22 μm microporous membrane to obtain the fine filtrate; (4) Take the fine filtrate to recover ethanol under reduced pressure, concentrate to 10 g raw and dried ginkgo leaves / ml concentrated juice, and set aside.

Embodiment 3

[0035] (1) Take dried ginkgo leaves and crush them into 650-mesh fine powder; (2) Take 10 kg of ginkgo leaf fine powder and add 250 kg of ethanol with a concentration of 55%, stir and mix evenly, soak for 4 hours, heat at 45°C, and set the speed at 25rpm, stirred and extracted twice, respectively, the first extraction was 3.5h, the second extraction was 2.5h, the combined extracts were filtered with 350 mesh industrial filter cloth, and the filtrate was centrifuged at 9000r / min for 15min to obtain the supernatant; (3 ) Take the supernatant and filter it with a 0.22 μm microporous membrane to obtain the fine filtrate; (4) Take the fine filtrate to recover ethanol under reduced pressure, concentrate to 10 g raw and dried ginkgo leaves / ml concentrated juice, and set aside.

Abstract

The invention discloses a ginkgo leaf extraction process and a method for processing ginkgo broadleaf holly leaf tea, which are characterized in that the ginkgo broadleaf holly leaf tea is prepared by extracting ginkgo leaves to obtain concentrated juice and then preparing the concentrated juice together with the broadleaf holly leaf tea; and the mass ratio of the ginkgo leave concentrated juice to the broadleaf holly leaf tea is 1:(10-20). The method for processing the ginkgo broadleaf holly leaf tea comprises the following steps of: uniformly spraying the ginkgo leave juice on the broadleaf holly leaf tea according to a proportion, so that the ginkgo leave juice is sufficiently and uniformly adsorbed; drying at the constant temperature of 55+ / -2 DEG C, so that the water content is below 5%; and carrying out vacuum packaging to obtain the ginkgo broadleaf holly leaf tea. The method for processing the ginkgo broadleaf holly leaf tea further comprises the following steps of: grinding the broadleaf holly leaf tea into 10-30-mesh powder; matching the powder with the ginkgo leave juice according to a proportion, so that the ginkgo leave juice is sufficiently and uniformly adsorbed; drying at constant temperature of 50+ / -2 DEG C, so that the water content is below 4%; and packaging the mixture into ginkgo broadleaf holly leaf tea bags, each including 2.0-2.5g, by using tea bag packaging papers. The ginkgo broadleaf holly leaf tea disclosed by the invention has the functions of clearing heat and decreasing grease and is more suitable for people suffering from headache, hot eyes and fever polydipsia to select and use.

Description

technical field [0001] The invention relates to the extraction of ginkgo leaves and the processing method of ginkgo kudingcha, in particular to the extraction process of ginkgo leaves and the processing method of gingko kudingcha. Background technique [0002] The medical and health value of Ginkgo biloba has been revealed by scholars at home and abroad. Ginkgo biloba contains more than 20 kinds of flavonoids, the content of which is greater than 24% in the total extract, mainly including Ginkgodiketone (Cinkgetin), isoflavone (So ginkgetin), bilobetin. Ginkgo biloba also contains terpene lactones. Diterpene lactones mainly include ginkgolides (Ginkgolide) A, B, C, M, J, etc., and sesquiterpene lactones are bilobalide. In addition, it also contains phenols, 25 kinds of beneficial elements, 17 kinds of amino acids, alkaloids and so on. Modern research has the functions of improving cardiovascular and cerebrovascular functions, relieving asthma, dilating coronary arteries, a...
