Phytochemicals from Tripterygium Wilfordii Hook. F. and Their Taxonomic Significance

To investigate the chemical constituents of Tripterygium wilfordii Hook. f. and their chemotaxonomic significance, twelve compounds were isolated and identified from this plant, including nine sesquiterpenoids (1-6, 8, 11-12), two monoterpenoids (9-10), and one lignan (7). The occurrence of compounds 1, 3-12 in Tripterygium has been reported for the first time. By analyzing the distribution patterns of these compounds across different plant taxa, the chemotaxonomic significance of the isolated compounds was systematically elucidated.
