Embodiment 1

[0025] 50% ethanol preparation of kumquat extract

[0026] Kumquat: purchased from the Suichuan planting base in Jiangxi Province, identified as the fruit of Fortunella Crassifolia Swingle, a plant of the genus Kumquat in the family Rutaceae, identified by Mr. Liu Yong from the School of Pharmacy, Jiangxi University of Traditional Chinese Medicine.

[0027] 1) Pre-treatment: After cleaning the fresh kumquat, crush it;

[0028] 2) reflux extraction: take by weighing 1 kg of kumquat after step 1 pulverization, add 3 times the amount of 50% ethanol aqueous solution, reflux extraction twice, the time of each extraction is 1, combine the extracts, reclaim ethanol with a rotary evaporator, Get kumquat extract extract. The yield of kumquat extract is 0.8%.

Abstract

The invention discloses a kumquat extract, a preparation method and application thereof. Kumquat extract is a kind of pure natural substance extracted from kumquat fruit. The present invention obtains the kumquat extract by ethanol reflux extraction, utilizes GC-MS to measure the main active components and content in the kumquat extract, and then proves that the kumquat extract and its active components can Significantly reduce vasoconstrictive blood pressure, regulate vasodilator factors such as angiotensin II, and at the same time reduce target organ damage caused by high blood pressure; through cell experiments, it has been proved that it can regulate the viability of HUVEC cells induced by angiotensin II. Therefore, kumquat extract has a good preventive effect on renal hypertension.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine, and in particular relates to a kumquat extract and a preparation method and application thereof. Background technique [0002] Kumquat, also known as Luofu (Oujiang Yizhi), longevity kumquat, milk orange (flower mirror), Gongsun orange, kumquat, etc., is the fruit of the Rutaceae kumquat plant Kumquat Fortunella margarita (Lour) Swingle, and the kumquat fruit is rectangular. Round or oval, golden yellow when ripe, the peel and pulp are difficult to peel off. Kumquat contains a variety of chemical components, mainly including flavonoids, volatile oils, polysaccharides and other compounds. Among them, Chen Ping and others analyzed the volatile components of kumquat fruit and identified 39 components, including 24 terpenes, 8 lipids, 1 alcohol, and 5 alkanes. Kumquat has a variety of pharmacological effects, currently found to have anti-oxidation, immune function regulation, blood lipid...
