TERPENOIDS, ALKALOIDS AND COUMARINS FROM BORONIA-INORNATA AND BORONIA-GRACILIPES

Aerial parts and roots of Boronia inornata yielded the sesquiterpenes spathulenol and 1 (10),5-germacradien-4-ol, the triterpenes moronic ac id, moronic aldehyde (novel), betulonic acid and lupeol, the alkaloids dictamnine, evolitrine, isodictamnine and hordenine, and 8-(3,7-dimet hyl-2, 6-octadienyl)-7-hydroxycoumarin. A second sample of B. inornata gave the protolimonoids niloticin and piscidinol-A in addition to all those compounds noted above. A sample B. gracilipes yielded spathulen ol, rutin and the triterpenes betulonic acid, betulonic aldehyde, olea nonic acid, 3-epioleanonic acid and oleanonic aldehyde. Results are no w available for investigations of species belonging to all three of th e sections of Boronia and the distribution of compounds is discussed.
