| 摘要: |
| 为了解沙棘压榨汁内漂浮物中脂溶性有色物质的成分,以黄龙沙棘鲜果为试样,用提取色素法;经溶剂提取和薄层色谱分离,得到8种有色物质,其中有一种对光比较稳定的黄色油状液体,经IR及H—NMR鉴定,谱图与有机物物理常数和光谱谱图册中油精的数据一致。又用UV测试,200～400nm无吸收峰;400～500nm有两处最大吸收峰。测定结果与相应谱图表明,经提纯的这种黄色油状液体是油精。 |

| Abstract: |
| In order to understand the compositions of coloured fat soluble substances in the floating matters in the pressed inice of Hippophae Rhamnoides, the fresh fruit of Hippophae Rhamnoides from Huang-Long was used as the materials to be extracted with solution using the pigment method, and with acetone , petroleum and then separated with thinlayer chromatography from which eight coloured substances were obtained, of which one yellowish oily liquid stable to light was identified using IR and H-NMR. The results were in agreement with the data of triolein with "Atlas of Spectral data and physical constant for organic compounds II" . Again, the substance was determined using UV, in 200-400 nm there were no absorbance peak values, but in 400-500 nm there were two highest absorbance peaks.The results and the corresponding spectral atlas showed that this yellowish oily liquid through purification was triolein. |
