摘要
木茎蓼又名木藤蓼,为蓼科蓼属植物(Polygonum aubertii L. Henry)的藤茎。该植物的入药部位藏医中医各不相同。中药用其块根,称为酱头,为湖南常德地区常用草药,民间称之为雄黄连。另外尚有赤地胆、丛叶蓼等别名。中医认为有清热解毒、调经止血之效。藏医则取其茎入药。据藏药木草记载,其味微热、甘、苦、涩,主治清热解表,治痛风特效。
The chemical ingredients of a tibetan medicinal herb, collected from South Gansu Tibetan Autonomous Region in August 1986 and identified as polygo-num aubertii (L.Henry) , have boon studied. From the aerol part of this herb, seven crystalline compounds have been isolated by extraction, liquid chro-matography and fractional recrystallization. Based on the chemical and spectral (UV, IR, 1H NMR, 13CNMR and MS) evidences, they were identified as α-L-butyl sorbopyranoside, 2,4-diphenylpyrrole, stagmast-4-en-3-one, stagmast-5-en-3-01-7-one, syringic acid, β-sitosterol, and tetracosanoic acid. These compounds have not been found in this herb previously.
