Compounds from aerial parts of Isodon lophanthoides and their effects of cytotoxicity and LPS-induced IL-1β and IL-10 production in RAW 264.7 macrophages
The bioassay-guided isolation of compounds from the aerial parts of Isodon lophanthoides (IL) resulted in the identification of five compounds (1–5). The chemical structures of 1–5 were determined through spectral analyses and compared to those identified in the literature to be 4-hydroxybenzoic acid (1), protocatechuic acid (2), rosmarinic acid (3), coetsoidin B (4), and coetsoidin A (5).
