title: A guanidine derivative from seeds of Plantago asiatica.
abstract: A new guanidine derivative named plantago-guanidinic acid was isolated from the seeds of Plantago asiatica. The structure was elucidated by two-dimensional (2D) nuclear magnetic resonance (NMR) spectral and other spectral methods.
