粟米脂质的分离与鉴定(Ⅱ)

Isolation and identification of lipoidal constituents in Setaria italica (Ⅱ)

目的 对粟米脂质的化学成分进行研究。方法 用色谱方法分离 ,波谱等方法鉴定成分结构。结果 从粟米的浸提物中分离得到 2个化合物 ,分别为甘油 - α,β-二亚麻酸酯 - α′-鼠李 -鼠李糖苷 ( )和一油酸甘油酯 ( )。结论 均为首次从该植物中获得 ,其中 为新化合物。

Object To study the lipoidal constituents of Setaria italica Beauv Methods The constituents were isolated by chromatography and structurally elucidated on the basis of spectral analysis Results The three glycerides were isolated as dilinolein (Ⅰ), monolinolenin (Ⅱ), α, β digalactosyl α′ linolenic glyceride (Ⅲ) Conclusion These compounds were obtained from the plant for the first time Compound Ⅲ is a new glycolipin
