研究厄瓜多尔药用植物长萼爵床的化学成分。采用常用色谱分离手段(硅胶柱层析、Sephadex LH-20柱色谱、ODS柱色谱及制备型高效液相色谱)对长萼爵床的95%乙醇提取物进行分离纯化,通过对光谱数据(包括IR、UV、HRESIMS和1D NMR)和理化常数... 研究厄瓜多尔药用植物长萼爵床的化学成分。采用常用色谱分离手段(硅胶柱层析、Sephadex LH-20柱色谱、ODS柱色谱及制备型高效液相色谱)对长萼爵床的95%乙醇提取物进行分离纯化,通过对光谱数据(包括IR、UV、HRESIMS和1D NMR)和理化常数的广泛分析,对化合物进行结构鉴定。实验结果显示从长萼爵床中共分离得到15个化合物,分别鉴定为羽扇豆醇(1)、α-菠甾醇(2)、corchoionoside C(3)、1-(4-hydroxy-3-methoxyphenyl)-2-[4-(3-hydroxypropyl)-2-methoxyphenoxy]-1,3-propanediol(4)、4-(2,3-dihy-dro-3-hydroxymethyl-5-(3-hydroxypropyl)-7-methoxybenzofuran-2-yl)-2-methoxyphenol(5)、5-styrylfuran-2-carboxylic acid methyl ester(6)、ferulyl aldehyde(7)、亚油酸甲酯(8)、3,7,11,15-tetramethylhexadec-2-en-1-ol(9)、α-亚麻酸(10)、3,7,11,15-tetramethyl-n-octadac-13-en-3,4,6,7,8,11-hexol-12-one(11)、对羟基苯甲酸(12)、2,4-二羟基苯甲酸甲酯(13)、桂皮酸(14)和3,4-二羟基苯甲酸(15)。以上化合物均为首次从该植物中分离得到。经抗病毒活性筛选,以上化合物均未表现出抗RSV和HSV-1活性;抗炎活性筛选结果表明,化合物1~7、14对LPS诱导的RAW 264.7巨噬细胞NO释放有一定的抑制作用。 展开更多

Objective:To investigate traditional uses of medicinal plant Justicia adhatoda L.by Meitei community in Manipur.Methods:Surveys were carried out in four districts in Central Valley of Manipur viz.,Imphal East,Imphal West,Bishnupur and Thoubal between 2008-2013 to collect information on the ethnobotanical uses of the species.Local people and Maiba/maibis(men/women healers)in the study areas were interviewed and preparation techniques of medicine and cuisines from the plant parts were demonstrated and photographed.Results:It was found that Meitei community in the study area extensively used Justicia adhatoda L.as ethno-medicine as well as food.Young and mature green leaves were used as traditional medicine in different ways to cure many ailments like cough,fever,asthma and dysentery.The ethnic community used inflorescences and leaves of the plant to prepare different cuisines for good digestion and health.Conclusions:Documentation of detailed ethnobotanical uses of individual plant species is need of the hour and it will help in understanding the in-depth knowledge about the role of species in the society. 展开更多
