Abstract

OBJECTIVE

To extract and analyze fatty acids in leaves of L. chinense Oliver and L. chinense var. rubrum Yieh.

METHODS

The fatty acids were extracted with Soxhlet extractor and identified by the GC-MS method.

RESULTS

31, 26 and 30 components were identified from the leaves of L. chinense, the green leaves and red leaves of L. chinense var. rubrum. There were 19, 14 and 16 kinds of fatty acid in the respective leaves, which accounted for 99.09%, 95.31% and 98.83% of the total extraction, respectively. The main components in the extraction were oleic acid (30.77%, 47.01%, 75.28%), linoleic acid (48.49%, 29.26%, 0%), hexadecanoic acid (9.83%, 8.87%, 11.71%), octadecanoic acid (3.86%, 3.18%, 4.88%) and docosanoic acid (2.37%, 2.17%, 2.58%).

CONCLUSION

Many kinds of unsaturated fatty acids exist in leaves of L. chinense Oliver and L. chinense var. rubrum Yieh. The leaves of these two plants can be used as the traditional Chinese medicine.

摘要

目的

提取并分析华榛叶和红花榛叶中的脂肪酸。

方法

采用索氏提取器提取脂肪酸，并用气相色谱-质谱联用法进行鉴定。

结果

从华榛叶、红花榛绿叶和红叶中分别鉴定出31、26和30种成分。各叶片中分别含有19、14和16种脂肪酸，分别占总提取物的99.09%、95.31%和98.83%。提取物中的主要成分是油酸（30.77%、47.01%、75.28%）、亚油酸（48.49%、29.26%、0%）、十六烷酸（9.83%、8.87%、11.71%）、十八烷酸（3.86%、3.18%、4.88%）和二十二烷酸（2.37%、2.17%、2.58%）。
