Dang, five triterpenoids, 24‐methylenecycloartanol (1), (23Z)‐cycloart‐23‐en‐3β,25‐diol (2), mollic acid (3), ursolic acid (4), 3β‐hydroxyurs‐11‐en‐28,13‐olide (5), together with two compounds, one C11‐norisoprenoid, loliolide (6), and one lignan, syringaresinol (7) were determined by using HR‐ESI‐MS, and NMR assignments. For the first time all compounds except 2were clarified from the genus Macrosolen, whereas, compound 2was verified from this species. |
