HPLC法测定不同产地功劳木中3个有效成分

目的测定功劳木中3,4,5-三甲氧基苯酚-1-O-β-D-葡萄糖苷(1)e、rythro-syringoylglycerol-8-O-β-D-glucoside(2)、5,5'-二甲氧基落叶松脂醇-4'-O-β-D-葡萄糖苷(3),为功劳木质量控制提供科学依据。方法采用高效液相色谱法,依利特Hypersil-C18柱(4.6 mm×250 mm,5μm);流动相为乙腈-水(14∶86);检测波长280 nm;体积流量1 mL/min;柱温25℃。结果化合物12,,3分别在0.12～2.40μg(r=0.999 5),0.20～4.00μg(r=0.999 6),0.07～1.40μg(r=0.999 6)与峰面积Y线性关系良好,平均加样回收率依次为100.3%,98.8%,97.2%(n=6)。结论该方法快速,简单,重复性好,适用于同时测定功劳木中化合物12,3,。

Two New Sesquiterpenoid Glucosides from the Aerial Parts of Saussurea involucrate

Two new sesqulterpenoid glucosides, namely α-hydroxycostic acid 6-β-D-glucopyranoside （compound 1） and 11 βH-11,13-dlhydrodehydrocostuslactone 8α-O-（6＇-acetyl）-β-D-glucopyranoside （compound 2）, along with 11 known sesqulterpenoids （compounds 3-13） were isolated from the aerial parts of Saussurea involucrate （Kar. et Kir.） Sch.- BIp. The structures of the new sesquiterpenoid glucosides were established by one- and two-dimensional nuclear magnetic resonance and mass spectrometry analysis.
