[Studies on the chemical constituents of Toricellia angulata var. intermedia].

Objective: To study the chemical constituents of Toricellia angulata var. intermedia.

Methods: The constituents were isolated and purified by repeated column chromatography and their structures were elucidated by spectroscopic analysis.

Results: Twelve compounds including beta-sitoterol (1), 7-hydroxy-3-ethylphthalide (2), 3beta-methoxy-stigmast-7-ene (3), stigmast-5-ene (4), trans-p-methylcinnamaldehyde (5), stigmate-7-en-3beta-ol (6), o. p-dimethoxybenzoicacid (7), beta-daucosterol (8), ursolicacid (9), stearic acid (10), docosanoic acid (11), palmitic acid (12) were isolated and identified from this plant.

Conclusion: All the compounds are isolated from the plant for the first time, compounds 3 -7, 10 -12 are isolated from this genus for the first time.
