Chemical constituents from twigs and leaves of Glycosmis montana / 中草药

ABSTRACT

Objective: To study the chemical constituents from the twigs and leaves of Glycosmis montana. Methods: The chemical constituents were isolated and purified by column chromatography on silica gel, MCI, and Sephadex LH-20 column, etc. The structures of compounds were elucidated by spectral analyses. Results: Twelve compounds were isolated and identified as hortiamide (1), dihydroalatamide (2), dictamnine (3), fagarine (4), glycofoline (5), isovanillin (6), N-p-coumaroyltyramine (7), epifriedelanol (8), friedelin (9), isoarborinol (10), vitexin (11), and kaempferol-3, 7-dirhamnoside (12). Conclusion: All the above compounds are obtained from G. montana for the first time, and compounds 1, 2, and 10-12 are obtained from the plants in genus Glycosmis Correa for the first time.
