Study on Chemical Components in Leaves of Amentotaxus argotaenia (Hance) Pilger Native to China

穗花杉叶化学成分的研究


Eight crystalline substances are isolated from leaves of Amentotaxus argotaenia na-
tive to China.  Five of them are identified as known A-homo-5-cholest-6-en-3-One,  cyclobala-
none, nonacosan-10-ol, r-sitosterol and β-sitosterol.  The others seem to be  new  components,
whose structures will be studied further.
