Phytochemistry and antimycobacterial activity of Chlorophytum inornatum

Bioassay-guided isolation of a hexane extract of Chlorophytum inornatum (Liliaceae) led to the characterisation of a new homoisoflavanone (1) as the major antimycobacterial compound. Minimum inhibitory concentration (MIC) values were moderate and ranged from 16 to 256 μg/ml against fast-growing Mycobacterium species.
