Pineapple weed DC.) is a widespread plant in Europe and North America. In ethnomedicine, it is well-known for its anti-inflammatory and spasmolytic activities. The aim of this research was to develop novel methods of processing to obtain essential oil and dry extracts and to investigate their phytochemical compositions. Moreover, the molecular docking of the main substances and the in vivo studies on their soporific and analgesic activities were conducted. The essential oil and two dry extracts from were prepared. A total of 16 phenolic compounds (seven flavonoids, seven hydroxycinnamic acids, and two phenolic acids) in the dry extracts were identified by means of UPLC-MS/MS. In the essential oil, nine main terpenoids were identified by gas chromatography (GC). It was shown that phenolic extraction from the herb was successful when using 70% ethanol in a triple extraction method and at a ratio of 1:14-1:16. The in vivo studies with rodents demonstrated the analgesic activity of the extracts and improvements in the sleep of animals. The dry extracts of did not show any toxicity. The molecular docking analysis showed a high probability of COX-1,2 inhibition and NMDA receptor antagonism by the extracts.
菠萝薄荷(Pineapple weed DC.)是一种广泛分布于欧洲和北美的植物。在民族医学中,它以其抗炎和抗痉挛活性而闻名。本研究旨在开发新的加工方法以获得精油和干提取物,并研究其植物化学成分。此外,还进行了主要物质的分子对接和体内催眠及镇痛活性研究。从菠萝薄荷中制备了精油和两种干提取物。通过 UPLC-MS/MS 鉴定出干提取物中总共 16 种酚类化合物(7 种类黄酮、7 种羟基肉桂酸和 2 种酚酸)。在精油中,通过气相色谱(GC)鉴定出 9 种主要萜烯。结果表明,当使用 70%乙醇进行三次提取,且料液比为 1:14-1:16 时,从草药中提取酚类物质是成功的。体内研究表明,菠萝薄荷的提取物具有镇痛活性,并改善了动物的睡眠。干提取物无毒性。分子对接分析表明,提取物极有可能抑制 COX-1、2 并拮抗 NMDA 受体。
