【摘要】 从珍珠草根中分离得到三个化合物,经物理常数、化学反应及光谱分析测定为兰雪醌(5—Hydroxy—2—methyl 1,4—naphthoquinone)、茅膏菜醌(3,5—Dihydroxy—2—methyl 1,4—naphthoquinone)、羟基茅膏菜醌(3,5,8—Trihy-droxy—2—methyl 1.4-naphthoquinone)。 珍珠草[Drosera peltata Sm.Var Lunata(Buch—Ham)Clarke]为茅膏菜科植物茅膏菜,又名地珍珠、一粒金丹、捕虫草等。 珍珠草主治腰疼、偏头疼、疟疾、翳障等。用珍珠草水蒸馏液制成注射液可治疗结核病,其提取物有强的大解疼、止疼及抗菌作用。云南丽江地区珍珠草资源丰富,人们以其根入药,治疗风湿及跌打损伤,疗效显著,已列入云南民族药。我们从云南丽江地区的珍珠草根的乙醚提取物中,分离得到几个化合物,研究工作如下:更多还原

【Abstract】 Three Constituents have been isolated from the root of drosera peltata Sm. Var Lunata (Bnch-Ham) Clarke. By means of spectral analysis and physico-chemical constants. they are identified to be 5 Hydroxy-2-methyl 1,4-naphthoquinone, 3,5-Dihydroxy-2-methyl 1,4-naphthoquinone and 3,5,8-Trihy- droxy- 2-methyl 1,4-naph- thoquinone.更多还原
