Mearnsetin is an O-methylated flavonol. It can be found in Eucalyptus globulus and in Elaeocarpus lanceofolius.[1] The compound has antioxidative properties.[2]

Mearnsetin 3,7-dirhamnoside can be found in the fern Asplenium antiquum.[3]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
