title: A polyacetylene and flavonoids from Cirsium rhinoceros.
abstract: Cirsium rhinoceros Nakai (Compositae) is a herbaceous perennial native to Korea, whole plant of which has been used in folklore medicine. C. rhinoceros was extracted by a standard extraction procedure. Its n-hexane, CHCl3 and n-BuOH extracts were fractionated by column chromatography to provide a polyacetylene, a coumarin and five flavonoids. Ciryneol C, scopoletin, acacetin, cirsimarin were isolated for the first time from this plant.
