摘要
目的:研究淡竹叶(Lophatherum gracile Brongn.)的化学成分。方法:采用各种色谱技术分离纯化,通过理化常数和光谱数据鉴定化合物的结构。结果:从淡竹叶中分离得到14个化合物,其中包括2个黄酮木脂素类成分及7个黄酮类成分,结构分别鉴定为salcolin A(1a)、salcolin B(1b)、苜蓿素(2)、木犀草素(3)、阿福豆苷(4)、苜蓿素7-O-β-D-葡萄糖苷(5)、当药黄素(6)、异荭草苷(7)、苜蓿素7-O-新橙皮糖苷(8)、牡荆素(9)、异牡荆素(10)、对甲氧基肉桂酸(11)、β-谷甾醇(12)和胡萝卜苷(13)。结论:化合物1a,1b,3～4,6～8和10～13均为首次从该植物中分离得到。
AIM： To investigate the chemical constituents of the leaves of Lophatherum gracile. METHODS： Isolation and purification were carried out by several column chromatographic methods. Compounds were identified based on their physicochemical properties and spectral data. RESULTS： Fourteen compounds were isolated from the leaves of L. gracile. The structures were elucidated as salcolin A （1a）, salcolin B （1b）, tricin （2）, luteolin （3）, afzelin （4）, tricin 7-O-β-D-glucopyranoside （5）, swertiajaponin （6）, isoorientin （7）, tricin 7-O-neohesperidoside （8）, vitexin （9）, isovitexin （10）, β-（p-methoxyphenyl） acrylic acid （11）, β-sitosterol （12） and daucosterol （13）, respectively. CONCLUSION： Compounds 1a, 1b, 3-4, 6-8 and 10-13 were isolated from this plant for the first time.
