[Studies on chemical constituents of Isodon excisoides].

The chemical constituents of the water extraction of the aerial parts of Isodon excisoides were investigated by various chromatographic methods including D-101 macroporous adsorptive resins, silica gel, Sephadex LH-20, MCI and semi-preparative HPLC. As a result, six compounds were separated and purified.By analyses of the HR-ESI-MS, 1D and 2D NMR spectra, their structures were determined as 3-O-β-D-allopyranosyl-1-octen-3-ol(1), blumenolA (2), lumichrome (3), loliolide(4), cirsiliol(5) and pedalitin(6). Compound 1 was a new compound, and compounds 2-4 were isolated from this plant for the first time.
