Abstract:Fractionation of an EtOAc-soluble fraction of the solid fermentate of an endophytic fungus, Lachnum abnorme Mont. BCRC 09F0006, derived from the endemic plant, Ardisia cornudentata Mez. (Myrsinaceae), resulted in the isolation of three new chromones, lachnochromonins D-F (1-3), one novel compound, lachabnormic acid (4), along with nine known compounds (5-13). Their structures were elucidated by spectroscopic analyses. Alternariol-3,9-dimethyl ether (6) was given the correct data as well as 2D spectral analyses for the first time. This is the first report of the isolation of one unprecedented compound 4 from Lachnum genus, while all known compounds were also found for the first time from Lachnum. The effects of some isolates (3, 4, 7-9, 10, and 13) on the inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-activated RAW 264.7 murine macrophages were also evaluated. Several compounds exhibited weak inhibitory activity on lipopolysaccharide (LPS)-stimulated NO production in RAW 264.7 macrophages.

Bioassay-guided fractionation of the active AcOEt-soluble layer from the whole plant of Amischotolype hispida resulted in the isolation of four new compounds, i.e., amisbenzoic acid (1), one butenolide derivative, amisnolide (2), one chlorin analog, amisphytin (3), one lignan, amislignol (4), and one metabolite isolated for the first time from nature, (À)-glaberide I (5), along with 20 known compounds, 6 -25. Their structures were elucidated on the basis of UV, IR, 1D-and 2D-NMR ( 1 H, 1 H-COSY, DEPT, HSQC, HMBC), as well as HR-ESI-MS, analyses. Among these isolates, palmitic acid (13) showed an antimycobacterial activity with an MIC value of 20.0 mg/ml against Mycobacterium tuberculosis H37Rv.
