Abstract

The invention belongs to the technical field of medicine preparation, and particularly relates to a eucommia ulmoides extract composition and a preparation method and application thereof. The composition comprises the following components: geniposidic acid, chlorogenic acid, aucubin, and a mixture of pinoresinol diglucoside and dehydrodiconiferyl alcohol diglucoside. The extract composition can effectively treat primary hypertension or kidney deficiency syndrome, has no toxic or side effect, is small in dosage, and can effectively reduce the medication cost.

Description

technical field [0001] The invention belongs to the technical field of medicine preparation, and in particular relates to an extract composition of Eucommia ulmoides and its preparation method and application. Background technique [0002] Hypertension refers to an increase in systemic arterial blood pressure (systolic blood pressure and / or diastolic blood pressure) as the main feature (systolic blood pressure ≥ 140 mm Hg, diastolic blood pressure ≥ 90 mm Hg), which may be accompanied by heart, brain, kidney and other organ functions Or clinical syndrome of organic damage. When the exact cause of high blood pressure cannot be found, it is called essential hypertension. [0003] There are many methods for treating essential hypertension in the prior art. For example, Chinese patent application CN103127421A discloses a traditional Chinese medicine composition for treating essential hypertension. , Motherwort, Millet Spatholobus, Chinese Yam, Eucommia. [0004] Chinese paten...
