[0022] The specific embodiments of the present invention will be described in detail below. In order to avoid too many unnecessary details, the well-known structures or functions will not be described in detail in the following embodiments. The approximate language used in the following embodiments can be used for quantitative expressions, indicating that a certain change in quantity is allowed without changing the basic function. Unless otherwise defined, the technical and scientific terms used in the following embodiments have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0023] A low-caffeine jasmine agarwood tea includes the following components by weight percentage: 5% of Aquilaria sinensis leaves, 5% of wild jujube seeds, 5% of rose petals, 10% of lilies, 25% of jasmine tea, 25% of wolfberry leaf tea, and 25% of decaffeinated green tea. The above components are brewed with 30 times the mass of drinking water at 80-90 °C for 10 minutes, and after cooling, a low-caffeine jasmine agarwood tea beverage is obtained.

[0024] Take 10 mL of this beverage, shake it well, add 0.5 g of magnesium oxide to it, and quickly shake it to make the magnesium oxide fully mixed with the tea beverage to be tested. Let it stand for a period of time until the upper layer solution becomes clear, and take 1 ml of the supernatant and filter it through a 0.22 μm microporous membrane.

[0025] Select a C18 chromatographic column with dimensions of 250 mm * 4.6 mm and a particle size of 5 μL. Mix methanol and water in a volume ratio of 30:70 as the mobile phase, and maintain a flow rate of 1.0 ml / min within 0 - 13 minutes; subsequently, within 13.1 - 15 minutes, the mobile phase gradually changes to methanol / pure water = 100 / 0, and the flow rate is increased to 1.2 ml / min; within 15.1 - 19 minutes, the mobile phase remains methanol / pure water = 100 / 0, and the flow rate is maintained at 1.2 ml / min; within 19.1 - 20 minutes, the mobile phase gradually changes back to methanol / pure water = 30 / 70, and the flow rate remains unchanged; within 20.1 - 25 minutes, the mobile phase remains methanol / pure water = 30 / 70, and the flow rate is reduced to 1.0 ml / min.

[0026] Set the monitoring wavelength to 272 nm, the injection volume to 10 μL, and maintain the column temperature at 35°C. Inject the caffeine standard at 5 μg / ml and the above-mentioned tea beverage respectively. The results show that the peak time of caffeine is 5.35 min. From this, the caffeine content of the above-mentioned tea beverage is calculated to be 0.23 μg / mL.

[0027] The following verifies the efficacy of the present invention through experimental methods.

[0028] Select 9 male rats at 6 weeks old of SPF grade with a body weight of 180 ± 15 g and 9 female rats at 6 weeks old with a body weight of 150 ± 12 g. After 1 week of adaptive feeding, start the experimental period after adapting to the environment.

[0029] Randomly divide the rats into a blank group, a conventional milk tea group, and a tea beverage group of the present invention (i.e., the above-mentioned low-caffeine content jasmine agarwood tea beverage), with 6 rats in each group.

[0030] The blank group is intragastrically administered with normal saline for 7 consecutive days; the conventional milk tea group is intragastrically administered with a beverage named "Assam Milk Tea" commercially available at a dose of 0.5 mL / 100g / d for 7 consecutive days; the tea beverage group of the present invention is intragastrically administered with the above-mentioned low-caffeine content jasmine agarwood tea beverage at a dose of 0.5 mL / 100g / d for 7 consecutive days.

[0031] 30 minutes after the last intragastric administration of the test sample, each group of animals is intraperitoneally injected with 10% chloral hydrate at a dose of 0.45 mL / 100g. Based on the disappearance of the righting reflex, observe and record the sleep latency of each group of rats. Take out the brain tissue and separate the cerebral cortex, hypothalamus, hippocampus, and brainstem. After rinsing with normal saline / PBS, weigh the mass and record respectively. Use the Elisa method to determine the content of 5-hydroxytryptamine and dopamine in the brain tissue. After anesthesia, open the abdominal cavity, collect blood from the abdominal aorta, centrifuge at 3000 r / min for 10 min at 4°C, take the supernatant, and use the Elisa method to determine the content of melatonin in the serum.

[0032] The experimental results show that the average sleep onset time of the mice in the blank group is 94.3 s, that in the conventional milk tea group is 127.2 s, and that in the tea drink group of the present invention is 73.1 s. The serotonin content in the hypothalamus of the mice in the blank group is 1.37 ng / mg, that in the conventional milk tea group is 1.88 ng / mg, and that in the tea drink group of the present invention is 1.30 ng / mg; the serotonin content in the hippocampus of the mice in the blank group is 1.29 ng / mg, that in the conventional milk tea group is 1.75 ng / mg, and that in the tea drink group of the present invention is 1.23 ng / mg; the serotonin content in the brainstem of the mice in the blank group is 1.24 ng / mg, that in the conventional milk tea group is 1.83 ng / mg, and that in the tea drink group of the present invention is 1.18 ng / mg; the serotonin content in the cerebral cortex of the mice in the blank group is 0.99 ng / mg, that in the conventional milk tea group is 1.47 ng / mg, and that in the tea drink group of the present invention is 1.02 ng / mg. The dopamine content in the hypothalamus of the mice in the blank group is 91 pg / mg, that in the conventional milk tea group is 120 pg / mg, and that in the tea drink group of the present invention is 91 pg / mg; the dopamine content in the hippocampus of the mice in the blank group is 80 pg / mg, that in the conventional milk tea group is 109 pg / mg, and that in the tea drink group of the present invention is 78 pg / mg; the dopamine content in the brainstem of the mice in the blank group is 96 pg / mg, that in the conventional milk tea group is 113 pg / mg, and that in the tea drink group of the present invention is 93 pg / mg; the dopamine content in the cerebral cortex of the mice in the blank group is 64 pg / mg, that in the conventional milk tea group is 87 pg / mg, and that in the tea drink group of the present invention is 58 pg / mg. The melatonin content in the serum of the mice in the blank group is 9.2 pg / mg, that in the conventional milk tea group is 8.8 pg / mg, and that in the tea drink group of the present invention is 9.1 pg / mg.

[0033] The above experimental results indicate that, compared with the blank group, the sleep onset time of the mice in the conventional milk tea group is significantly prolonged, while the tea drink group of the present invention shortens the sleep onset time to a certain extent. In addition, in the mice gavaged with conventional milk tea, the contents of serotonin and dopamine in the brain tissue increase to varying degrees, while the tea drink of the present invention does not affect the contents of serotonin and dopamine. In addition, the present invention does not affect the melatonin content in the serum, and thus has no potential impact on the biological rhythm.

[0034] The above has described the embodiments of the present invention in detail, but the described content is only the preferred embodiments of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the scope of the application of the present invention shall be included within the protection scope of the present invention.
