Embodiment 1

[0018] Example 1: Bukitschyl Alcohol Concentration-Dependent Diastolic Effects of Potassium Chloride Precontracted Endothelialized Vascular Rings

[0019] 1 Materials and Instruments

[0020] 1.1 Drugs and preparation

[0021] Patchouli medicinal material was collected from the patchouli planting base in Yangchun County, Guangdong Province in November 2012. It was identified as Pogostemon cablin (Blanco ) Benth.) whole plant.

[0022] Take 40Kg of the dried above-ground part of Patchouli medicinal material, use a large-scale improved steam distillation device to extract, dry and remove water through anhydrous sodium sulfate, and finally obtain 215g of Patchouli volatile oil. Use silica gel column chromatography (100-200 mesh, 5Kg, 20×150cm) to chromatographically separate the volatile oil, use petroleum ether-acetone (100:0-0:100) as the mobile phase for gradient elution, and the eluent passes through thin layer For chromatographic detection, fractions with similar composit...

Abstract

The invention discloses application of patchouli alcohol in preparation of an endothelium-independent vasodilator. The invention further discloses a medicine for treating cardiovascular and cerebrovascular diseases caused by endothelial injury. The medicine is a preparation prepared from patchouli alcohol serving as an active ingredient and pharmaceutically acceptable excipients or auxiliary components. The patchouli alcohol has an endothelium-independent vasodilation effect, and has clinical significances for treating the cardiovascular and cerebrovascular diseases.

Description

technical field [0001] The invention relates to a new application of buccal alcohol, in particular to an application in the preparation of an endothelium-independent vasodilator, which belongs to the field of medicines. Background technique [0002] Vasodilators are mainly used in the treatment of hypertension, congestive heart failure, myocardial ischemia, cerebral ischemia and peripheral vasospasm diseases. Vasodilators can be divided into two categories according to the vasodilation pathway: endothelium-dependent vasodilators, which refer to the synthesis and secretion of NO and PGI that rely on functional and structurally intact vascular endothelial cells 2 , EDHF and other vasodilation factors increase and / or ET-1 and other vasoconstriction factors caused by vasodilation drugs; release of NO, K + channel activation, and / or Ca 2 + Drugs that cause vasodilation, such as channel blockers. [0003] Studies have confirmed that the occurrence and development of cardiov...
