Three new cyclopentanoid monoterpenes, named piscrocins A , B and C, were isolated from the roots of Picrorhiza scrophulariiflora (Scrophulariaceae). The structures of these new compounds were established by 1D and 2D NMR spectroscopic techniques ( (1)H- (1)H COSY, HMQC, HMBC, and NOESY) in combination with X-ray crystallographic analysis.
从玄参科胡黄连（Picrorhiza scrophulariiflora）的根中分离出三种新的环戊烷类单萜，命名为胡黄连素A、B和C。这些新化合物的结构通过一维和二维核磁共振光谱技术（¹H-¹H COSY、HMQC、HMBC和NOESY）结合X射线晶体学分析得以确定。
