Abstract:
This study was performed to investigate the guaianolides from the aerial parts of Artemisia myriantha. The chemical constituents were isolated by chromatographic columns over silica gel, Sephadex LH-20, and ODS, as well as Semi-prep HPLC methods, and their structures were identified by NMR and MS data. Ten compounds were isolated and identified as follows: artemyriantholide E (1), tanaphillin (2), 1β, 10β-epoxydehydroleucodin (3), 5-hydroxyleucodin (4), dehydrocostuslactone (5), 3-O-methyl-iso-secotanapartholide (6), roxbughianin A (7), dehydroleucodin (8), arglabin (9), and 8α-acetoxyarglabin (10). Compound 1 was a new compound, and compounds 2-7 were isolated from this plant for the first time. Compound 3 exhibited selective cytotoxicity against human liver cancer (Bel-7402) with IC₅₀ value of 5.35 μmol·L⁻¹, and 6 against human gastric cancer (BGC-823) with IC₅₀ value of 2.68 μmol·L⁻¹, respectively.
