Three new cyclopentanoid monoterpenes from Picrorhiza scrophulariiflora

Abstract Three new cyclopentanoid monoterpenes, named piscrocins A (1), B (2) and C (3), 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...

Zusammenfassung:	Abstract Three new cyclopentanoid monoterpenes, named piscrocins A (1), B (2) and C (3), 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.
