目的:分析比较香樟树枝、树叶、树皮中脂溶性成分。方法:将香樟树枝、树叶、树皮3个不同部位分别用甲醇渗漉提取后再用石油醚萃取,采用GC-MS法分析和鉴定其脂溶性成分,并用峰面积归一化法计算各成分相对百分含量。结果:从香樟树枝中共分离鉴定出10种化学成分,主要为植醇(49.64%)、α-松油醇(7.86%)、橙花叔醇(7.50%);从香樟树叶中共分离鉴定出13种化学成分,主要为植醇(62.37%)、橙花叔醇(10.98%);从香樟树皮中共分离鉴定出19种化学成分,主要为α-松油醇(13.45%)、植醇(8.10%)、棕榈酸(7.75%)、丁香酚(6.82%)、(Z,Z,Z)-9,12,15-十八三烯酸甲酯(5.90%)、棕榈酸甲酯(5.41%)。结论:为进一步探讨香樟不同部位的药理作用及合理开发利用该植物资源提供一定的科学依据。
OBJECTIVE: To analyze and compare fat-soluble components in camphor branches, leaves and barks. Methods: Three different parts of camphor tree branches, leaves and bark were extracted with methanol percolation and then extracted with petroleum ether. The fat-soluble components were analyzed and identified by GC-MS method and calculated by peak area normalization Relative percentage of ingredients. Results: Ten chemical constituents were isolated and identified from camphor branches, including phytol (49.64%), α-terpineol (7.86%) and nerolidol (7.50%). Thirteen chemical constituents were isolated, mainly composed of phytol (62.37%) and nerolidol (10.98%). Nineteen chemical constituents were isolated and identified from camphor bark, mainly α-terpineol (13.45% (Z, Z, Z) -9,12,15-octadecadienoic acid methyl ester (5.90%), palmitic acid (7.75%), eugenol (6.82%), methyl palmitate (5.41%). Conclusion: This study provides a scientific basis for further exploring the pharmacological effects of different parts of Campanula and developing and utilizing the plant resources rationally.
