ABSTRACT
Two new compounds, namely integrin A (1) and integrin B (2), were isolated from the supercritical fluid extract (SFE) of Artemisia integrifolia L. Their structures were elucidated by spectroscopic methods, including UV, IR, HR-ESI-MS and extensive 1D and 2D NMR techniques.

Two new compounds, named ordosacid A (5) and ordosacid B (6), along with four known compounds: 3,4-dihydroxybenzaldehyde (1), p-hydroxybenzoic acid (2), p-hydroxycinnamic acid (3) and o-hydroxycinnamic acid (4), were isolated from the ethyl acetate extract of Artemisia ordosica Krasch. The structures of new compounds were elucidated on the basis of spectroscopic methods including UV, IR, ESI-MS, 1D NMR, 2D NMR, HR-ESI-MS and modified Mosher's method.

A new compound, integracid (1), together with four known compounds were isolated from the dichloromethane (CH2Cl2) extract from Artemisia integrifolia L. The structures of compounds (1-5) were elucidated by spectroscopic methods, including ultraviolet, infrared (IR), high resolution-electrospray ionization-mass spectrometry (HR-ESI-MS) and extensive one-dimensional (1D) and two-dimensional (2D) nuclear magnetic resonance (NMR) techniques, and by comparison with data reported in the references. Antibacterial activities of the compounds were evaluated against various bacteria.
