Abstract: Three new C27-steroidal glycoalkaloids, spiralosides A-C (1-3), were obtained from the total alkaloids of Solanum spirale by chromatographic methods. On the basis of spectroscopic evidence, spiralosides A-C were elucidated as (22R,25S)-22,26-epiminocholest-5-ene-3β,16α-diol-N-acetyl-3-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl (1), (22R,25S)-22,26-epiminocholest-5-ene-3β,16α-diol-N-acetyl-3-O-β-D-glucopyranosyl (2), (22R,25S)-22,26-epiminocholest-3β,16α-diol-N-acetyl-3-O-β-D-glucopyranosyl (3), respectively. The total alkaloids of S. spirale have been screened for their antitussive and expectorant effects in intact animal model.
