The methanol extract of Leontopodium haplophylloides which has been used as a folk remedy in Tibetan yielded four rare unsubstituted B-ring flavonoids. Their structures were established as pinocembrin(1), galangin (2), 5-methoxy-7-hydroxy flavonol (3) and 7-methoxy-5-hydroxy flavonol (4) on the basis of spectral method. Galangin (2) had high activity against human skin bacterium which cause acne vulgaris.
