Marsileagenin A (750) which is a hexahydroxylated oleanane type triterpene is a major sapogenol of the saponins obtained from Marsilea-minuata (Marsileaceae) 409), Such highly oxidized triterpenes are quite unusual in ferns though they occur frequently in seed plants. 

The fact that rutin occurs in Marsilea and Regnellidium (Marsileaceae), but not in the Pilularia suggests that Regnellidium is probably a derivative of Marsilea and not an intermediate in a complexion or reduction between Pilularia and Marsilea 200).
