To study the chemical constituents of the roots and rhizomes of Asarum longerhizomatosum. Chromatography and spectral analysis were used to isolate the constituents and elucidate their structures. Five compounds were isolated from the ethanol extracts of the roots and rhizomes, and identified as asarone(I), beta-sitosterol(II), 2,4,5-trimethoxybenzaldehyde(III), 4-(2,4,5-trimethoxyphenyl)-3-en-butylone(IV) and 3 beta-hydroxystigmast-5-en-7-one(V). All the compounds were isolated from the plant for the first time, and IV is a new natural product.
