Embodiment 1
[0018] Example 1: Compound (I) Separation Preparation and Structure Confirmation
[0019] Sources of reagents: ethanol, petroleum ether, ethyl acetate, n-butanol, and dichloromethane were of analytical grade, purchased from Shanghai Lingfeng Chemical Reagent Co., Ltd. Methanol, of analytical grade, were purchased from Jiangsu Hanbang Chemical Reagent Co., Ltd.
[0020] Separation method: (a) Grind Houttuynia cordata (2kg), extract with 65% ethanol under heat reflux (20L×3 times), combine the extracts, concentrate until no alcohol smell (4L), and then use petroleum ether (4L×3 times), ethyl acetate (4L × 3 times) and water-saturated n-butanol (4L × 3 times) were extracted to obtain petroleum ether extract, ethyl acetate extract and n-butanol extract respectively; (b) step ( a) The n-butanol extract is removed with AB-8 macroporous resin, first eluted with 10% ethanol for 12 column volumes, then with 70% ethanol for 15 column volumes, collected 70% eluate, and reduced Concentra...
Embodiment 2
[0024] Embodiment 2: pharmacological action
[0025] In this example, nitroglycerin was used to prepare a rat model of migraine, and the anti-migraine effect of the drug on increasing 5-hydroxytryptamine (5-HT) and decreasing calcitonin gene-related peptide (CGRP) was observed.
[0026] 1. Materials and methods
