Embodiment 1

[0023] The preparation method of above-mentioned sandalwood leaf extract adopts supercritical CO 2 Extraction method, the specific steps are as follows: take the leaves of dalalbergia, crush them to 10 meshes, put them in the extraction kettle, cool the evaporator tank, set the temperature: the temperature of the extraction kettle is 25°C, the temperature of the first separation kettle is 25°C, the temperature of the first separation kettle The temperature of the second separation kettle is 25°C. Heat the extraction kettle, the first separation kettle and the second separation kettle. At the above set temperature, supercritical CO 2 extraction, open the CO 2 Gas cylinder, and open the high-pressure pump to pressurize the extraction kettle, the first separation kettle, and the second separation kettle. The extraction pressure is 20Kpa. After the pressure is stable, open the vent valve to discharge the residual air. The pump is used for circular extraction, and 0.5 times the a...

Embodiment 2

[0025] The preparation method of above-mentioned sandalwood leaf extract adopts supercritical CO 2 Extraction method, the specific steps are as follows: take the leaves of dalalbergia, crush them to 80 mesh, put them in the extraction kettle, cool the evaporator tank, set the temperature: the temperature of the extraction kettle is 40°C, the temperature of the first separation kettle is 40°C, and the temperature of the first separation kettle The temperature of the second separation kettle is 40°C. Heat the extraction kettle, the first separation kettle, and the second separation kettle. When the temperature of the refrigerator drops to 0-2°C, the temperatures of the extraction kettle, the first separation kettle, and the second separation kettle respectively reach the above-mentioned When pre-set value, perform supercritical CO 2 extraction, open the CO 2 Gas cylinder, and open the high-pressure pump to pressurize the extraction kettle, the first separation kettle, and the s...

Embodiment 3

[0027] Get 800 grams of sandalwood leaves, put them in the extraction kettle, and cool the evaporator tank. Set the temperature of the extraction kettle to 40°C, the temperature of the first separation kettle to 40°C, and the temperature of the second separation kettle to 40°C. To 0-2 ℃, when the temperature of the extraction tank, the first separation tank, and the second separation tank reach the preset value respectively, the supercritical CO 2 extraction, open the CO 2 Gas cylinder, and open the high-pressure pump to pressurize the extraction kettle, the first separation kettle, and the second separation kettle. The extraction pressure is 20-30Kpa. After the pressure is stable, open the vent valve to discharge the residual air. After reducing part of the pressure, close the vent Valve, start the pump to carry out circular extraction, and add 1 times the amount of absolute ethanol as an entrainer, extract at constant temperature and pressure for 2 hours, and you can get the...

Abstract

The present invention discloses applications of dalbergia odorifera t.chen leaves in prevention and treatment of high blood pressure. The present invention further provides a dalbergia odorifera t.chen leaf extract, a preparation method for the dalbergia odorifera t.chen leaf extract by using a supercritical CO2 extraction method or a steam distillation method, and applications of the dalbergia odorifera t.chen leaf extract. According to the present invention: the dalbergia odorifera t.chen leaves are adopted as raw materials, such that agriculture and forestry wastes are completely utilized, and comprehensive development and utilization values of the dalbergia odorifera t.chen are increased; ethanol and water are adopted as extraction solvents, and the obtained extract does not contain organic solvents harmful for human body, such that safety is high; when the extract is used for treatment of high blood pressure diseases, an advantage of rapid onset is provided, blood pressure can maintain stability after drug discontinuance 3 days, and no side effect is provided; and the dalbergia odorifera t.chen leaf extract of the present invention can be used for drugs for prevention and treatment of high blood pressure, health products and daily necessities.

Description

technical field [0001] The invention relates to an extract of sandalwood leaves for treating hypertension, in particular to an application of sandalwood leaves and a preparation method of the extract. Background technique [0002] Hypertension refers to increased arterial systolic and / or diastolic blood pressure (>=140 / 90mmHg) in a resting state, often accompanied by disorders of fat and glucose metabolism, as well as functional or organic diseases of the heart, brain, kidney, retina and other organs. sex change. Hypertension is a common cardiovascular and cerebrovascular disease in many countries in the world, especially among the middle-aged and elderly people. Arterial embolism can lead to serious consequences such as cardiac dysfunction, myocardial infarction, coronary heart disease, and cerebral thrombosis. The prevalence of hypertension in our country has risen significantly. According to the current epidemic trend survey, the form of control is not optimistic. my...
