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 3β- O-trans-ferulyl-2α-hydr...

Summary: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 3β- O-trans-ferulyl-2α-hydroxy-urs-12-en-28-oic acid, 3β- O-cis-ferulyl-2α-hydroxy-urs-12-en-28-oic acid, 2α- O-trans-ferulyl-3β-hydroxy-urs-12-en-28-oic acid, 3β- O-cis-coumaroyl-2α-hydroxy-urs-12-en-28-oic acid and 5,7-dimethoxy-6-methylflavone.
