STUDIES ON THE CHEMICAL CONSTITUENTS OF ANNONA SQU AMOSA SEED

    摘要
  • 摘要: 从番荔枝Annona squamosa L.种子的乙醇提取物分得三个polyketide类化合物:squamostatin-8(Ⅰ),annonin-vl(Ⅱ)和desacetyluvaricin(Ⅲ)以及胡萝卜甙(daucosterol,IV)。其中Ⅰ是一种新的polyketide,经光谱解析方法,测定了Ⅰ的化学结构式和部分碳原子的立体化学.

     

    Abstract: A new polyketide,squamostatin-B(Ⅰ),two known polyketides, annonin-Ⅳ(Ⅱ)and desacetyluvaricin(Ⅲ),and daucosterol(Ⅳ)have been isolated from Annona squamosa L.(Annonaceae).The structure and relative stereochemistry of I were elucidated on the basis of spectralanalvsis of I and its acetate(Ia) and mesitoate(Ib)。
