A beta-Hydroxychalcone from Leptospermum scoparium.
A beta-hydroxychalcone 1, so far not reported as a natural compound, was separated from the diethyl ether extract of LEPTOSPERMUM SCOPARIUM (Myrtaceae). Furthermore, three known flavonoids 2-4 were isolated. The (13)C-NMR spectra of 2-4 are reported, since they have as yet not been reported in the literature.
