Embodiment 1

[0050] Embodiment 1: Preparation of Agarwood extract of the present invention

[0051] (1) After pulverizing 500 g of agarwood, reflux extraction with 4 L of 95% by volume ethanol aqueous solution for 2 hours to obtain an extract; repeat the extraction twice in the same way, and combine the extracts.

[0052] (2) Concentrate and dry the extract obtained in step (1) under reduced pressure to obtain 93g of extract; dissolve the extract with 500ml of water, extract 3 times with petroleum ether (1000ml / time), and combine the extracts 3 times to obtain petroleum ether extract; and then extract the aqueous layer with ethyl acetate 3 times (1000ml / time), and combine the three extracts to obtain the ethyl acetate extract.

[0053] (3) The ethyl acetate extract obtained in step (2) was concentrated and dried under reduced pressure to obtain 46 g of ethyl acetate extract.

Abstract

The invention provides lignum aquilariae resinatum extract. The lignum aquilariae resinatum extract is characterized in that the lignum aquilariae resinatum extract is prepared by the aid of a method including steps of (1), smashing lignum aquilariae resinatum and extracting the lignum aquilariae resinatum by the aid of methanol or ethanol aqueous solution to obtain extract liquid; (2), concentrating and drying the extract liquid obtained in the step (1) under normal pressures or reduced pressures to obtain extract cream, or carrying out spray-drying on the extract liquid to obtain powder, then dissolving the extract cream or the powder in water to obtain solution, extracting the solution by the aid of petroleum ether to obtain petroleum ether extract liquid, and extracting aqueous layers by the aid of ethyl acetate to obtain ethyl acetate extract liquid; (3), concentrating and drying the ethyl acetate extract liquid obtained in the step (2) under reduced pressures to obtain extract cream, or carrying out spray-drying on the ethyl acetate extract liquid to obtain powder. The lignum aquilariae resinatum extract and the method have the advantage that the lignum aquilariae resinatum extract or a pharmaceutical composition with the lignum aquilariae resinatum extract can be used for preparing medicines for preventing and / or treating diseases due to glucose and lipid metabolism disorder.

Description

technical field [0001] The invention belongs to the technical field of pharmacy. Specifically, the present invention relates to the use of the plant extract extracted from the Agarwood plant in the preparation of medicines for diseases caused by glucose and lipid metabolism disorders. Background technique [0002] Insulin resistance (Insulin Resistance, IR) refers to the reduced responsiveness of the body to the physiological effects of insulin, which is manifested in the decreased sensitivity of peripheral tissues to insulin and the impairment of glucose utilization. The main reason is that due to the reduction of high-calorie diet or physical activity, as well as other aging factors, stress state, genetic factors, etc., the response of the target tissue of the body to insulin is weakened, and the ability of insulin to maintain blood sugar is reduced. Fat and protein and other substance metabolism disorders and energy metabolism disorders (Liu Liping. Establishment of insu...
