  1. 新疆雪蓮與蕨化學成分之研究 • 本研究探討新疆雪蓮及蕨植物之化學成分，由新疆雪蓮70%丙酮的萃取物和蕨甲醇的萃取物藉由管柱層析分離純化出九個化合物，化合物之化學結構是以並藉由各種光譜(MS、旋光度、X-ray、1D和2D NMR)的數據解析所確立。新疆天山雪蓮部分的兩個化合物，分別為(－)-11βH-11,13-dihydrodeh-ydrocostus lactone-8-O-β-D-glucoside (SI-1)和quercetin(SI-2)，而SI-1為新疆雪蓮之特徵化合物。蕨部份則有七個化合物，分別為p-hydoxybenzoic acid (PA-1)、kaempferol-3 -O-β-D-glucopyranoside (PA-2)、3-(1-C-β-D-glucopyranosyl)- 2,6 -dihydroxy-5-methoxybenzoic acid) (PA-3)、(－)- (7S,8R)-Dihydrodehydrodiconiferyl Alcohol 4-O-β-D- glucopyranoside (PA-4)、(＋)-(7S,8S,7''S,8''S)-pinoresinol- 4-β-D-gluco-pyranoside (PA-5)、(－)-(2S,3S,7''R)-2-(4''-O-β-D-glucopyranosyl-7''- amino-3''-methoxybenzyl)-3-(6"-amino-4"-hydroxy-3"-methoxybenzyl)tetrahydrofuran(PA-6)、β-sitosterol galactopyranoside (PA-7)、(PA-8)，PA-1~PA-5以及PA-7為已知化合物，但PA-3、PA-4、PA-5、PA-7為首次在此植物中發現，而PA-6為一個新化合物。
