title: Three new cyclopentanoid monoterpenes from Picrorhiza scrophulariiflora.
abstract: 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.
