Objective: To investigate the chemical constituents of the aerial parts of Pogostemon cablin.
Methods: The constituents were isolated by column chromatography over silica gel, Sephadex LH-20 and C8. Structures were identified by spectroscopic data analysis.
Results: Thirteen compounds were obtained and elucidated as patchouli alcohol (1), pogostone (2), friedelin (3), epifriedelinol (4), oleanolic acid (5), methyl oleanolate (6), 5alpha-stigmast-3,6-dione (7), stigmast-4-ene-3-one (8), beta-sitosterol (9), pachypodol (10), retusin (11), (-)-guaiacylglycerol (12) and dibutyl phthalate (13).
Conclusion: Compounds 6, 7, 8, 12 and 13 are isolated from this genus for the first time.
