TRITERPENOIDS AND FLAVONOIDS FROM LEPTOSPERMUM-SCOPARIUM

An investigation of the dichloromethane extract of Leptospermum scoparium afforded seven 3-substituted triterpenoid acids, four of which were novel, and eight methylated flavonoids including one new flavone. The new compounds were identified by their spectroscopic data as 3 beta-O-trans-ferulyl-2 alpha-hydroxy-urs-12-en-28-oic acid, 3 beta-O-cis-ferulyl-2 alpha-hydroxy-urs-12-en-28-oic acid, 2 alpha-O-trans-ferulyl-3 beta-hydroxy-urs-12-en-28-oic acid, 3 beta-O-ciscoumaroyl-2 alpha-hydroxy-urs-12-en-28-oic acid and 5,7-dimethoxy-6-methylflavone.
