1-O-Acetylbritannilactone has anticancer activity, it suppresses angiogenesis and lung cancer cell growth possibly via regulating the VEGFR-Src-FAK signaling, it also can combine with gemcitabine elicits a potent apoptosis of lung cancer cell. 1-O-Acetylbritannilactone may serve as a novel therapeutic intervention for various cardiovascular diseases, including chronic ischemia, by regulating VEGF signaling and modulating angiogenesis; it is a potent inhibitor of LPS-stimulated VSMC inflammatory responses through blockade of NF-kappaB activity and inhibition of inflammatory gene COX-2 expression. 1-O-Acetylbritannilactone may act as potent natural skin-lightening agents, it exhibits anti-melanogenic activity by suppression of tyrosinase expression via ERK and Akt signaling.

Violanthin is a flavone C-glycoside that is flavone substituted by hydroxy groups at positions 5, 7 and 4', a beta-D-glucopyranosyl residue at position 6 and a 6-deoxy-alpha-L-mannopyranosyl residue at position 8. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor and a plant metabolite. It is a trihydroxyflavone and a flavone C-glycoside. It is functionally related to a flavone.
