Chemical Constituents of Litsea euosma
- 12 Downloads
The genus Litsea is one of the most diverse genera of evergreen trees or shrubs belonging to Lauraceae and comprises roughly 200–400 species that are distributed abundantly throughout tropical and subtropical Asia and North and South America. This genus is represented by 72 (47 endemic) species in China. Litsea euosma W. W. Sm. is mainly distributed in the subtropical regions of China, such as Guangdong, Guangxi, Hunan, Jiangxi, Sichuan, Guzhou, and Yunnan. Its fruits, roots, and leaves are frequently used in traditional Chinese medicine to treat stomachache, dyspepsia, and arthritis, and to tonify spleen dropsy [1, 2].
As part of an ongoing research on biologically active constituents from Litsea genus, which find use in ethnomedicine as a treatment for infectious diseases, we studied the chemical constituents of the leaves and twigs of L. euosmacollected from Yunnan in August 2013 and identified by Prof. Yu Chen of Kunming Institute of Botany, Chinese Academy of Sciences.
