Phytochemical investigation of the aerial parts of Pourr. resulted in the isolation and characterization of a new isoflavan, ()-2',4'-dihydroxy-3'-methoxy-6,7-methylenedioxyisoflavan- 4-ol (), and a new monoterpene, ()-4-hydroxy-2,2,6-trimethyl-9-oxabicyclo [4.2.1] non-1(8)-en-7-one (), together with four known flavonoids: geinstein , chrysin , chrysin -7--β-D-glucopyranoside and 2″--α-L-rhamnosylorientin . The structures of the new compounds were elucidated on the basis of extensive spectroscopic analysis, including 1D, 2D NMR (H, C, COSY, TOCSY, HMBC and HSQC) and HRESIMS. The absolute configurations of and were established by the comparison of experimental and calculated electronic circular dichroism (ECD) spectra.
对Pourr.地上部分进行植物化学研究，结果分离并鉴定出一种新的异黄烷，即()-2',4'-二羟基-3'-甲氧基-6,7-亚甲基二氧基异黄烷-4-醇()，以及一种新的单萜，即()-4-羟基-2,2,6-三甲基-9-氧杂双环[4.2.1]壬-1(8)-烯-7-酮()，同时还有四种已知的黄酮类化合物：盖因斯坦、白杨素、白杨素-7--β-D-吡喃葡萄糖苷和2″--α-L-鼠李糖基荭草素。新化合物的结构通过广泛的光谱分析得以阐明，包括一维、二维核磁共振（氢谱、碳谱、COSY、TOCSY、HMBC和HSQC）以及高分辨电喷雾电离质谱。化合物和的绝对构型通过实验和计算的电子圆二色光谱（ECD）的比较得以确定。
