Objective To study the chemical composition of the above-ground dried parts of Hyssopus cuspidatus Boriss. Methods The constituents were isolated and purified by silica gel column and high performance liquid chromatography techniques repeatedly, and the resulting compounds were structurally characterized by modern wave spectroscopy techniques to determine the structures of the compounds, and the isolated compounds were screened for in vitro inhibitory activity against human gastric cancer HGC-27 cell line using MTT colourimetric assay. Results A total of nine compounds were isolated from the 95% ethanol extract of H. cuspidatus. and were identified as: 4S-(2-hydroxyisopropyl)-cyclohexane-2-en-1-one (1), (3R,4aR,5R,6R)-6-hydroxy-4a,5-dimethyl- 3- (prop-1-en-2-yl)-3,4,4a,5,6,7-hexahydronaphthalen-1(2H)-one (2), p-anisic acid (3), salvigenin (4), 5-hydroxy-6,7,3',4'- tetramethoxy flavone (5), cirsimaritin (6), E-p-coumaryl alcohol ethyl ether (7), (E)-p-coumaryl alcohol γ-O-methyl ether (8), 4-hydroxy-3-methoxy ethyl cinnamate (9). Wherein, compound 1 is a new compound. The antitumor activity screening of compounds 1-9 showed that compounds 1, 3 and 8 had certain inhibitory effects on HGC-27 gastric cancer cells, and their IC50 values were 8.76, 16.34, 25.28 μmol/L, respectively. Conclusion Compound 1 is a new compound. Compounds 5-9 were first isolated from this genus.
