Objective:
To investigate the anti-HIV constituents from the root of Mirabilis jalapa.
Method:
The compounds were isolated by column chromatography on silica gel, Sephadex LH - 20, MCI-gel CHP-20P and RP-18. The structure were identified by means of NMR and MS analyses (1H-NMR, 13C-NMR, MS).
Result:
Eleven compounds were isolated and identified as astragaloside II (1), astragaloside II (2), astragaloside IV (3), astragaloside VI (4), flazin (5), 4'-hydroxy-2, 3-dihydroflavone 7-beta-D-glucopyranoside (6), gingerglycolipid A (7), 3, 4-dihydroxybenzaldehyd (8), p-hydroxybenzaldehyde (9), beta-sitosterol (10) and daucosterol (11).
Conclusion:
Compounds 1-9 were obtained from this genus for the first time.
