An epimer of cleomiscosin A, it is isolated from the aerial parts of Rhododendron collettianum and exhibits inhibitory activity towards the enzyme tyrosinase. It has a role as a metabolite and an EC 1.14.18.1 (tyrosinase) inhibitor. It is a member of phenols, an aromatic ether, an organic heterotricyclic compound, a delta-lactone and a primary alcohol."}]
