Abstract

Two rare alkaloids, 1-(2-,N-methylpiperidyl)-butan-2-one (1) and l-(2-N-methylpiperidyl)-pentan-2-one (2), were identified from the medicinal plant Pratia nummularia. The structure of 1 was elucidated by means of spectroscopic methods. Compound 2 was established by spectral comparison with synthetic material.
