Abstract:
Objective: To investigate the chemical constituents from the aerial part of Rabdosia flexicaulis. Methods: Various column chromatography techniques were used to isolate and purify the compounds and their structures were identified by the spectral data. Results: Fifteen compounds were isolated and identified as rotundic acid (1), tormentic acid (2), corsolic acid (3), 23-hydroxyursolic acid (4), maslinic acid (5), teuclatriol (6), 3,6-dihydroxy-1-menthen (7), 1- hydroxypinoresinol (8), epipinoresinol (9), lariciresinol (10), caffeic acid (11), rosmarinic acid (12), 3'-O-methyl-rosmarinic acid (13), methyl 4'-O-methyl-rosmarinate (14), and methyl 3-dehydroxyl-rosmarinate (15). Conclusion: All the compounds are isolated from the species for the first time, among which compounds 1, 6, 7, 9, 13, and 14 are isolated from the plants in genus Rabdosia (Bl.) Hassk. for the first time.
