Embodiment 1
[0051] Example 1: Extraction, separation and structure confirmation of oleanol-type benzofuran and its glycosides A, B, C, D, E, F, G, H, I, J
[0052] Extraction and separation: Take 2.2kg (dry weight) of the fruit of Styrax perkinsiae (Styrax perkinsiae, collected from Yongde County, Yunnan Province), grind it, and extract it with 80-90% industrial alcohol 25L at room temperature for 3 times, each time for 7 days . The extract was concentrated in vacuo to obtain 550g of total extract, which was suspended in 5L of hot water, extracted 5 times with petroleum ether, chloroform and n-butanol in sequence, each time with 5L of solvent, and the extract was concentrated respectively to obtain extract: Petroleum The ether fraction was 16 g, the chloroform fraction was 200 g, and the n-butanol fraction was 120 g. Samples were taken for in vitro activity screening, and both the chloroform and n-butanol fractions showed estrogen-promoting activity. Put the chloroform part on a silica ...

Abstract
The invention discloses the application of egonol-type benzofuran and glycosides thereof in the preparation of an ACAT (Acyl-CoA:Cholesterol Acyltransferase) inhibitor, provides the application of egonol-type benzofuran as shown in general formula I and glycosides thereof in the preparation of the ACAT inhibitor, and further provides the drug combination of the ACAT inhibitor, which contains egonol-type benzofuran and glycosides thereof with the active component being shown in the general formula I. The egonol-type benzofuran and the glycosides thereof can be prepared into various forms of drug, such as tablets, capsules and the like, because of the significant effect of the ACAT inhibitor thereof. The invention is suitable for preventing and treating diseases, such as angina, myocardial infarction, cerebral infarction, Alzheimer's disease, acute coronary syndromes (ACS), percutaneous transluminal coronary angioplasty (PTCA) or post-stenting coronary restenosis; and the invention, as a therapeutic agent for regulating the sebaceous gland function and inhibiting the excessive production of sebum, is also suitable for curing diseases, such as oily skin, acne, seborrhea, acne-like lesion caused by corticosteroid and the like.
Description
technical field [0001] The present invention relates to a new application of a compound of general formula, specifically, the present invention relates to the preparation of oleanol-type benzofuran and its glycosides for the prevention and / or treatment of angina pectoris, myocardial infarction, cerebral infarction, cerebral apoplexy, and ear Use in drugs for Alzheimer's disease, acute coronary syndrome, coronary artery restenosis after PTCA or stent placement, and oily skin, acne, seborrhea, and acne-like lesions caused by corticosteroids. Background technique [0002] The accumulation of cholesteryl ester in a large area of blood vessels will cause atherosclerotic lesions and form fat-rich plaques. The destruction of fat-rich plaques will form thrombus and block the coronary lumen, which will lead to acute coronary syndrome, angina pectoris, and myocardial infarction. and other diseases. The formation of plaques formed by atherosclerotic lesions in the carotid arteries a...
