Abstract:
OBJECTIVETo study the chemical constituents in the spikes of Schizonepeta tenuifolia.
METHODCompounds were isolated and purified with silica gel, ODS and Sephadex LH-20 gel column chromatography, and their structures were determined by using spectroscopic analysis including MS and NMR.
RESULTNine compounds were isolated and identified as 5, 7-dihydroxy-6, 4'-dimethoxyflavone (1), 5, 7-dihydroxy-6, 3', 4'-trimethoxyflavone (2), ursolic acid (3), 3-hydroxy-4(8)-ene-p-menthane-3(9)-lactone (4), 5, 7, 4'-trihydroxyflavone (5), 5, 4'-dihydroxy-7-methoxyflavone (6), hesperidin (7), luteolin (8) and daucesterol (9).
CONCLUSIONCompounds 1, 2, 6 were first obtained from the spikes of S. tenuifolia.
