A method for the determination of the pyrrolizidine alkaloids from Seneciojucobueu (Compositae) by 'H and I3C NMR is presented. 'H NMR is a reliable method for the determination of the total alkaloid level. I3C NMR appears to be a suitable method for the determination of the individual alkaloids. Th

## Abstract Pyrrolizidine alkaloids (PAs) are common constituents of many plant species around the world. PA‐containing plants are probably the most common poisonous plants affecting livestock and wildlife. They can inflict harm to humans through contaminated food sources, herbal medicines and diet

In this study, a 267-Β΅m-diameter solenoid transceiver is used to acquire localized 1 H NMR spectra and the measured signal-to-noise ratio (SNR) at 500 MHz is shown to be within 20-30% of theoretical limits formulated by considering only its resistive losses. This is illustrated using a 100-Β΅m-diamet
